    Contrary to what I am seeing in comments on HN, this is not just for single family detached housing. If you go to the ZERH website, under Program Requirements it says:

    Versions 1 and 2, Single Family, Multifamily, and Manufactured Homes

    https://www.energy.gov/eere/buildings/zero-energy-ready-home...

    Additionally, one of the photos in the featured article has the following caption:

    Lopez Community Land Trust built this 561-square-foot affordable home on Lopez Island, Washington, to the high-performance criteria of DOE's Zero Energy Ready Home program that delivers a $20-per-month average monthly energy bill.

    I've said for years we need to go back to more passive solar design as our baseline standard because it is both more energy efficient and more comfortable for humans. It protects the environment while improving quality of life.

    It's a myth that you can't see gains in both areas.

    I'm also happy to see the caption because we need to do a better job of supporting high quality of life in small towns, not just big cities. Trends in recent decades mean small towns suck because they lack services and big cities suck if you aren't one of the wealthy.

    That wasn't always true and programs like this can improve and strengthen both small town and urban environments while mitigating the burden suburbs currently represent.

      What makes you think that project is relying on passive solar? In green building that concept has been largely superseded by newer standards like Passive House and Net Zero which generally rely more on air sealing and super-insulation with highly insulated windows.

        You are correct that they are viewed as different systems and tend to rely on different strategies:

        https://ecokit.us/passive-solar-design-vs-passive-house/#:~:....

        To me, it's almost a matter of semantics.

        In passive solar building design, windows, walls, and floors are made to collect, store, reflect, and distribute solar energy, in the form of heat in the winter and reject solar heat in the summer. This is called passive solar design because, unlike active solar heating systems, it does not involve the use of mechanical and electrical devices.[1]

        The key to designing a passive solar building is to best take advantage of the local climate performing an accurate site analysis.

        https://en.m.wikipedia.org/wiki/Passive_solar_building_desig...

        I think of passive solar as the umbrella term for such strategies. My understanding is passive house comes from a German project. It shouldn't surprise anyone that strategies which work well in Germany differ from strategies that work in warmer climates.

        There are also traditional building approaches in Middle Eastern deserts that keep the entire city at bearable temperatures. They historically built on a plateau, oriented streets to be cooled by prevailing winds etc.

        Both in Mexico and Iran, they have passive air exchange systems that help cool homes. Stairwells in Victorian American homes have similar features and likely served a similar purpose and were probably not merely ostentatious.

        If you know a better umbrella term for this approach, I'm open to suggestions.

          > My understanding is passive house comes from a German project. It shouldn't surprise anyone that strategies which work well in Germany differ from strategies that work in warmer climates.

          It actually started in North America around the time of the oil embargo as a mechanism to reduce energy costs. (See the history section of https://en.m.wikipedia.org/wiki/Passive_house). Once that shock passed, people went back to not caring.

          Even at the time, and still today, most write ups are focused on harsh climates like New England or Canada in Winter, because it's harder. It's also the case that in milder climates, the cost to make your home passive has historically been higher than just paying the subsidized bills (and/or requires capital). So most of the US hasn't cared (again) until recently.

          There is going to be a lot of health fallout though as people start having oxygen depletion from tightly-sealed houses.

          It's important that even well sealed homes have both A/C fresh air sources as well as ERV/HRV systems that can recapture the heat/cold the house has while replacing the CO2 with outside air.

          • schiffern 2 years ago
            >oxygen depletion

            I wish people would stop conflating low oxygen with high CO2.

            Even at 5000 ppm CO2 (which "significantly impair" attention, executive function, and risky decision-making[0]), the oxygen has only dropped from 20.95% to 20.45%. This ~2.5% difference is negligible, equivalent to natural variations in atmospheric pressure.

            The buildup of CO2 is the issue, not the depletion of O2.

              In addition to concerns relating to carbon dioxide levels, when I contemplate the push for ever-more-tightly-sealed homes and particularly smaller homes with lower ratios of internal air volume to internal surface area (of walls, built-ins like cabinetry, and furniture), the issues stemming from outgassing of volatile organics from the adhesives and sealants as well as from the materials (solid wood became plywood with wood veneering, became sawdust-and-binder with plastic faux-wood veneer, etc.) now composites made of multiple substances and multiple binders and glues.

              Some years back, "sick building syndrome" was a prominent topic of discussion and there was a push for fresh air, windows that opened, etc. but this seems to have largely dropped off the radar, afaict.

                ERVs and HRVs are generally part of these designs. Also, nothing stops people from cracking open their windows. The windows are meant to insulate well when closed.

                  I followed you up to the end when you say cities didn't always have more services than small towns and that life in a city wasn't that bad if you were poor. If I think of industrial era first bigger cities, this doesn't seem true? It was way bigger gap between rich and poor quality of life and I'm pretty sure cities always had more services, that's what makes them cities.
                  • DoreenMichele 2 years ago
                    I can see why you read it that way, but that's not the point I was trying to make.

                    These days, a lot of small towns don't even have a full-service grocery store and many people who want to live in a small town have to commute a long ways to get basic essential food they need.

                    Historically, they may also not have had a full-service grocery store, but a lot more people lived and/or worked on farms and a lot more food was sold locally, not far from where it was grown.

                    There are essential services that have been unraveling in recent years, making it really challenging to baseline survive in a small town in a way that wasn't always true. And it should not be true that you have a gun to your head to own a car in order to have any hope of having an adequate diet. That's just seriously problematic for individuals and even potentially threatens welfare or survival of the human race.

                    Something has gone very wrong that it's so hard for so many people to get a decent meal when we are awash in so much societal wealth, yet our systems for how it gets distributed and such have gotten so out of whack.

                    • pbhjpbhj 2 years ago
                      It doesn't negate your point, but here in the UK, in a village of <1000, mostly elderly people; with a couple of buses a day; nearest market town is several miles away .. people order shopping online, and some suppliers (eg fresh fish, local farm vegetable boxes) bring a van around.

                      Even in rural areas you can get supermarket home delivery, it costs a few quid for the delivery but is considerably cheaper than car ownership.

                      Pretty much everyone has cars though.

                        “ a lot more people lived and/or worked on farms and a lot more food was sold locally, not far from where it was grown”

                        But they’re not living/working on farms, nor are they living near where the food is grown. Our agriculture system is capable of delivering huge amounts of food for people (including the people who live near fields), but it’s not exactly trying to do that as doing that is not economically efficient.

                        (Edit)

                        Maximum solar energy is on the equatorial side of the house.

                        Full-sun plants prefer maximum solar energy.

                        10ft (3m) underground it's about 75°F (24°C) all year. Geothermal systems leverage this. (Passive) Walipini greenhouses are partially or fully underground or in a hillside, but must also manage groundwater seepage and flooding; e.g. with a DC solar sump pump and/or drainage channels filled with rock.

                        Passive solar greenhouses (especially in China and now Canada) have a natural or mounded earthen wall thermal mass on one side, and they lower wool blankets over the upside-down wing airfoil -like transparent side at night and when it's too warm (with a ~4HP motor).

                        TIL an aquarium heater can heat a tank of water working as a thermal mass in a geodesic growing dome; which can be partially-buried or half-walled with preformed hempcrete block.

                        Round structures are typically more resilient to wind:

                        Round house: https://www.pinterest.com/search/pins/?q=round%20house

                        The shearing force due to wind on structures with corners (and passive rooflines) causes racking and compromise of structural integrity; round homes apparently fare best in hurricanes.

                        It seems unbelievably stupid to me to build solar panel based homes where I live: the northwest US.

                        Makes a heck of a bunch of sense in CA or TX though.

                        • DoreenMichele 2 years ago
                          Passive solar design is about creating a home which needs little energy to stay at a comfortable temperature. It's unrelated to generating electricity via solar power panels.
                          • Maakuth 2 years ago
                            The northwest US doesn't seem* to be worse than most of the Europe, where we have a veritable boom of solar power. Granted, it produces next to nothing during the winter, but the yearly production makes it profitable still. Even for well insulated house you need some heating in the north, but it can be surprisingly little. It's not like these houses are going to be built totally without network mains.

                              Solar is more effective in low temperatures than in high temperatures. Also northwest US is max around 49 degrees north, which is around Paris in Europe and it is normal to have solar much farther north in Europe

                                Solar panels are extremely popular in Stockholm, 59 degrees North and less than 1,000 km from the Artic Circle. During winter, they produce very little electricity, admitedly... but they work well in all the other seasons so they still significantly reduce electricity consumption.

                            I just see this as another subsidy for single family housing developments.

                            The home may be "zero energy ready" or whatever greenwashing term they want to use. But the fact is they are spending that energy in driving from the sticks (in some cases >20 miles away) and back, driving from their home to the grocery store and back, driving to areas of interest (ie, parks, restaurants, doctors appointments).

                            All of this is dependent on highways and new roads, new electrical, water, and sewage infrastructure. This is all very expensive to build and maintain, and the cities and municipalities are left to foot the bill.

                            American housing is a Ponzi scheme and this only helps perpetuate it. We need to reverse this trend with significant investments in public transportation and other alternative forms of transportation which can scale to meet the needs of the future. We need to build vertically and re-claim back the resources allocated for car centric design (ie, highways, parking lots, parking garages, roads, street parking) and re-allocate it for more housing, businesses, and public transportation. Entities that can generate new income for the municipality and city.

                            In parallel, can work to preserve our existing natural green spaces and hopefully over time expand those green spaces which give us breathable air, drinkable water, protection from natural elements (ie, floods or long periods of torrential rain), and help keep viruses and other bad elements out of human populations.

                              I'm no expert in this field, but I think that changing zoning in current suburbs to mixed use would go a long way towards fixing them. The central wards of Tokyo are surrounded by such mixed use residential areas and it works extremely well, with most necessities being within walking distance or at worst biking distance.

                              It wouldn't fix the suburbs' lack of density, but it'd still be a marked improvement. It'd theoretically lighten the burden suburbs place on cities too, since there'd be a lot more corner shops and the like paying taxes.

                              • twblalock 2 years ago
                                People keep bringing up Tokyo but it's not really relevant. Yes, Tokyo has mixed zoning. But it was developed the way it is because the people who live there want it to be that way. It's also only livable because the people there have a culture that makes it possible to live in high density without high levels of crime, noise, and filth.

                                Americans in the same situation would not have built something like Tokyo.

                                If you're going to bring up Tokyo you should also bring up Houston. Houston is what most American cities would look like if the people who lived there were able to build what they wanted. Most Americans want to live in detached homes that they own, and they prefer cars to public transit.

                                  Most people just want what they're already accustomed to.

                                  We quite literally have the power to influence that instead of just throwing our hands up and saying "well gosh Americans want terribly designed communities whose long-term costs are completely unsustainable, so I guess there's nothing we can do about it."

                                  This isn't some immutable law of the damned universe.

                                              Well in the city where I live (Minneapolis) they've been tearing down houses in several areas of the cities where post-world war II architecture was abundant. Small houses (under 1,500 sq ft) with a small front yard and back yard. The very typical "American Dream" kind of a starter house.

                                              Now they're getting bought up and the people are literally building houses from every end of the lot, often time getting variances for setbacks. They've decided that yards and green space are no longer important. They want wedge a three story 5K sq ft house on the same lot where a much smaller home fit.

                                              So, I would agree and say to an extent, people are already there in terms of dealing with no lawns, now its just getting them to accept several houses on the same lot instead of their massive mcmansion.

                                                I think we are on our way there, most new developments around here have houses that are nearly the size of the lot, with a tiny back yard and smaller front yard, and little room between houses. Developers get more money by making lots small and houses big, so there’s little incentive to have the large suburban d yards that wises to be common.

                                                Of course, the houses are much larger than their Japanese counterparts. My Japanese mother in law thinks we are wealthy based on the size of our house, but we’re one of the smallest homes in the neighborhood,

                                                    Generally speaking, people will always choose to spend money living as close to their ideal as they can, with the resources they are able to give toward it.

                                                    The fact that so many people choose to live in suburbs, or the "sticks", suggests that there is something desirable to _them_ about living there. I.e. the same spending power required to live in a house in the suburbs, or rurally, could usually be used to live in higher density living, closer to urban centers, but instead they choose to suffer long commutes and expensive transportation in order to enjoy a different lifestyle.

                                                    I think it's naive to suggest that "American housing" is a Ponzi scheme.

                                                      "Happy City" by Charles Montgomery brings an interesting angle on the typical urban planning story by focusing largely on how we can plan cities and communities to maximize happiness. In the book, he discusses that people have this "ideal" of moving to the suburbs, owning their own house, etc, but then the long commutes, isolation of living in a car-dependent neighborhood, dangers of living among high-speed cars, etc. all lead many people to actually be less happy overall after moving to the suburbs.

                                                      So I think that some of this fact that the suburbs are desirable is not necessarily completely rational, and may instead be heavily influenced by the idea that moving to suburbs is what they grew up seeing as their future (due, of course, to federal programs that incentivized suburbanization) and by auto-industry lobbying and marketing that idealizes a car-dependent lifestyle.

                                                      Obviously there will be variability and I'm sure many people enjoy a suburban/rural lifestyle more than they would a city lifestyle. But I don't know if a preference for suburban living is really part of our human nature, and I think assuming that it is can be detrimental as it can take effort away from recreating the peace and quiet and nature access in a way that is accessible to all in a more efficient urban setting.

                                                        Well said - I don't fully agree, but I agree that an automobile centered world is sub-optimal, and fuels our feelings of disconnection.

                                                        I'm fully on-board with working to make suburbs more self-contained and walkable. As others have said, the issue may be zoning and regulations.

                                                            I think your comment is a bit misleading.

                                                            Dumping sewage into a creek is an externality that is bad.

                                                            Someone preferring to live in a suburb does not mean they're generating externalities at that level.

                                                            The very reason I pushed back on the comment was because of this black and white thinking.

                                                            seems condescending to me. As though "those" people don't have the character or moral rectitude to live in the city. Maybe I'm reading in more than you intended.

Development spread out over a broad area is very expensive to maintain. Over a life cycle, a city frequently receives just a dime or two of revenue for each dollar of liability... Decades into this experiment, American cities have a ticking time bomb of unfunded liability for infrastructure maintenance. The American Society of Civil Engineers (ASCE) estimates deferred maintenance at multiple trillions of dollars, but that's just for major infrastructure, not the local streets, curbs, walks, and pipes that directly serve our homes. Every mature city has a backlog of deferred maintenance, a growing list of promises with no discernible path to make good on them."

We don't need perfectly smooth streets, so defer minor maintenance makes sense. Most unmeetable promisees are things they never intended to meet.

The only two that seem quite urban in the top 15 to me are New York County and San Francisco County.

They can't afford that much space in the city, which in turn is so expensive because the amount of high density housing is artificially limited by zoning.

                                                                          You have to let the market decide how much high density housing there should be before you can score "the market has decided" as a point.

                                                                                Instead, I have a 3400 sq ft house on 10,000 sq ft of land with giant trees everywhere. I'm within 2 miles of lightrail, that I will never use.

                                                                                I work from home, I have a home office with a indoor, led powered garden with fresh fruit and flowers year round.

                                                                                Again, why would I buy near or in any city? 15 minutes from downtown Denver is to close for my taste.

                                                                                I love theatre, I love restaurants but honestly, I hate driving in Denver. The traffic sucks. I love driving. I love craft coffee, my house is 1 mile from the coffee factory that makes the coffee whole foods uses; I enjoy a craft coffee from that place once in a while.

                                                                                Why is walkable so desired? When it's cold (like today) I don't want to leave my car. I'd drive through any day, I'd drive just to avoid walking half a mile.

                                                                                Denver banned the scooters and other options from lyft and bird, so I have to lug my giant body from location to location? No thanks, I'll take my 4000 pound car to the restaurant instead.

                                                                                Then I'll go home, enjoy my big beautiful yard and not worry about living in the city.

                                                                                I don't go to the gym, instead I have a treadmill and a bike in my basement.

I live in Denver and am currently staring at a dozen Lyft scooters and a few bikes parked on the corner next to my apartment. Lime also operates scooters and bikes, which I usually see parked across the street at the apartments next door.

In cities whose populations actually embrace their being cities (vs. centers of suburban agglomerations), you find destinations close enough to walk, safe and plowed bike paths, fast and frequent buses, and extensive train networks.

                                                                                            Clearly walkable neighbourhoods are highly desirable, and in the US people pay a massive premium to get them because they are so scarce. Yet, for some reason, new construction in the suburbs is all disconnected and almost never walkable.

                                                                                            There's a huge disconnect between what people want and what developers are actually building. The kind of density that leads to walkability seems to only occur in older and already expensive areas with infill development, never green field construction further from an existing city center.

                                                                                            Maybe it's impossible to build new walkable areas in the US.

For a childless couple, the cost of a 3 bedroom house in the suburbs might be the same as for a one room apartment in the city. If they choose the suburbs, maybe they're choosing more than location, they're also choosing quality of life.

For example, most would rather a personal car rather than the bus, but that makes bus stops less frequent due to less ridership which then makes cars even more desireable.

                                                                                              Or flight from urban crime to the suburbs then makes urban crime more likely for the remaining people, who then have more reasons to flee.

Rural communities receive a disproportionately large amount of federal aid per capita in order to build and maintain the infrastructure that makes that lifestyle possible.

                                                                                                    You could say similar things about LA, or the areas outside Chicago and NYC, etc. They are definitely suburban, and definitely not rural.

However, from what I've seen it is almost always monetarily cheaper to create your own services when possible - unless a neighbor has paid for services to get really close. It might make sense for neighbors to pool money for pulling services out. It all depends on the specifics, right?

In the suburbs, it's expected that you'll get to your local grocery store and find healthy foods available at reasonable prices. In a food dessert, your local 15 grocery stores/bodegas/whatever you all them, won't have access to healthy foods. You might see a banana, or something, and it'll cost 4x what it would cost at a regular grocey store, hence there's an affordability aspect, to it, too.

                                                                                                                  If you're 20 miles outside a town, you almost certainly have electrical service, but are on a well and septic system. City water and sewer doesn't make sense at those sort of densities. You also probably have the land to easily put a nice ground mount PV array in, and grow a good bit of your own food, should you care to.

                                                                                                                  • rascul 2 years ago

You won't generally find septic systems on properties under about an acre. Not that it never happens, obviously, but a septic field has geographic requirements that means you won't often see it in a suburban neighborhood.

Taken to extreme, we could make sure a square kilometer is at least two stories tall, but we don't do that. We live mostly a in 2.5d environment.

                                                                                                                          The skyscrappers that we see in our skylines are not even the majority of what we see. A lot of place will benefit from being 3-4 stories tall.

                                                                                                                          A lot of space that is developed is hugely wasted, devoted to storing cars, or roads to facilitate car movement. Meanwhile, a human being is very compact in comparison.

                                                                                                                            Walmart and Kroger like having big operationally efficient stores that they can operate like all their other stores, and can’t scale their model well to oddball village locations. So they make or buy a big building with a giant parking lot and underprice all the local stores with their hyperoptimized business model until the village is dead.

                                                                                                                            At that point, there’s nothing left to do in your dense housing district and everybody needs a car anyway, so you may as well have some breathing room and a garage.

                                                                                                                            If people want suburban density, it won’t come from zoning changes (although that will help urban density) — it’ll come from somehow making village commerce more economical. But good luck getting that kind of effort past national-retail lobbyists!

                                                                                                                            Ultimately, again, the fact is that urban development issues are different than the issues in other areas and the solutions don’t need to come at the expense of each other or in competition with each other.

                                                                                                                        • danans 2 years ago

                                                                                                                                        First, you do know that when you get a house you actually get the house, right? That’s the value residents extract from the house. Whether my parents could resell their house was only relevant when they needed to, big shocker, move to a different house in another area. Apart from leaving something for inheritance the re-sale value was irrelevant to the utility. That’s antithetical to a Ponzi scheme.

                                                                                                                                        Second, anyone can build more housing and there is tons of land to keep building in 90% of the country. That doesn’t work in a Ponzi scheme if the real value that sets the price is margin that can be captured by builders.

                                                                                                                                        • throwaway894345 2 years ago

We need to be more flexible and realistic with our environmentalism--people just aren't going to give up meat, cars, or houses overnight so we need to allow progress where we can actually get it.

                                                                                                                                              There are many small towns in Europe surrounded by networks of even smaller towns and one or two house farms. There is nothing to claim back there: they've been like that since well before any European moved to the Americas. That was a way to be close to fields, when economy was mostly farmers and herders and people mostly walked or at best moved in animal powered carts.

                                                                                                                                              Some people move from there to big cities now, some people move from big cities to there. Everybody has a car, it can't be helped. I think that people in big cities will end up with public transport and few cars, but people in small towns and in the fields or in the hills or mountains will keep having a car, maybe just use it less if it costs too much.

It is honestly mind boggling how far some people drive to go to work here. I'm in The Netherlands around Eindhoven. We have colleagues in Den Bosch, Utrecht and Maastricht driving to work every week. Eindhoven is full of commuters.

                                                                                                                                                Some people take the train, but that isn't always convenient, especially with strikes! Your boss doesn't care that you were 3 hours late due to a bus skipping out on work. Your paycheck cares a lot though.

                                                                                                                                                Back in America, most people I knew lived and worked in the same general region/city. Perhaps this is a uniquely Dutch problem owing to the size of the country, but I don't see how they can reduce car usage without significantly more investment in public transportation. By the looks of the current state of the government, that's not going to happen anytime soon.

(The average times for transit are quite high in the US, but 90% of commutes are by car so a large portion of that 10% are by car).

                                                                                                                                                    Huh? Where did you get this nugget of wisdom from? We have great relationships with almost all of the neighbors I can see from my porch. It's called community. I've lived in urban high rises and known fewer neighbors.

Houses usually cost more than condos - so you're paying more property tax already by having a more expensive home...

And as gas taxes have remained fairly constant, while roads have become more expensive to repair as they get worse, I can only think that number has gone up since then.

                                                                                                                                                                          Do you have any sources for that? I'm in Australia, where fuel costs about twice what it does in the US. A decent portion of that is taxes/duties, but road spending is taken from consolidated revenue, and fuel taxes ultimately contribute a minority of the spending on roads. So unless the cost of fuel production is massively lower in the US, something doesn't add up.

                                                                                                                                                                        • ars 2 years ago

                                                                                                                                                                            I've got a large ground mount solar install I put in a few years ago (15.9kW nameplate, though mostly east-west facing panels so a bit less annual production than you'd expect, just more "sunup to sundown" production), and it's been a chilly winter, so with an air source heat pump and keeping the house fairly cool, I'm still net +4MWh from the grid in the last 4 months.

                                                                                                                                                                            Meanwhile, when it warms up a bit more, I'm generating 10x what the house uses during spring/fall mornings (10+ kW production on a sub-1kW house draw for long periods of the day). It's not a big deal with only a few people on the grid, but if every house were doing this, it would be a very big problem for grid stability.

                                                                                                                                                                            I've also got experience with the off-grid lifestyle, as my office is 100% off-grid/standalone, and I don't pretend that system is cheap. Just neat. And even with 5kW of solar hung for a ~100 sq ft shed, I still need propane or a generator in the winter every now and then to keep things sane in here.

                                                                                                                                                                            • londons_explore 2 years ago

                                                                                                                                                                              When the price of power is high in the winter, companies will swoop in with gas turbines, power cables from other places, and extra insulation to keep houses warm with lower energy costs. Entrepreneurs will see this coming, and will be there ready to provide power or power-saving measures to those who did not prepare.

                                                                                                                                                                              As long as the market can set a price, the market will solve each problem. The people to lose out will be customers who don't adapt to keep their costs down - for example those who heat their 1960's uninsulated home with electric baseboard heaters.

                                                                                                                                                                              There are already plenty of seasonal industries - like tourism. Power hungry industries will become seasonal or migratory too.

After you've bought the building, the smelter, and the guy to operate it, the cost of electricity to smelt aluminum is negligible. Its never going to make sense to leave all that idle if the cost of electricity bumps up a few cents.

Cost of electric is a very large issue. We pay workers extra to work overnight shifts when electric is cheaper and shut down during the day. We also shutdown for annual maintenance in December when Christmas lights raise electric costs.. not one that melts metal, but I know one plant runs 5 months and does maintenance the other 7.

                                                                                                                                                                                  Note, the above is as of 10 years ago. Now wind provides most electric so hours may be different to account for that.

If you're not well situated for panels you can invest in batteries and sell at night what you bought during the day.

                                                                                                                                                                                    I don't have your faith in markets though. The invisible hand is a potent force indeed, but it's just as likely to flip you the bird as it is to solve a problem that you have. There's nothing about a market, for instance, that knows to keep prices high enough to prevent the wintertime aluminum smelters from burning all the stored energy and causing a humanitarian crisis a month later when there's not enough to weather a blizzard.

                                                                                                                                                                                      Imagine you see all the power being used up ahead of winter, and you predict this problem... Yet it seems like nobody else has noticed...

                                                                                                                                                                                      So you swoop in and, with profits in mind, you buy up some electricity futures contracts for December. They're quite cheap right now, and you suspect that when the blizzard hits they'll be really valuable. By doing so, you push the price of them up a bit.

                                                                                                                                                                                      Meanwhile, Fred over at the hydro plant sees that futures contracts for electricity are higher in December than now, so he'll make more money by switching off the generators now and using that water later in December when he'll get paid more for it.

                                                                                                                                                                                      Bob at the aluminium smelter sees that spot prices for power now are higher (because the hydro shut off), and futures prices suggest they'll be even higher in December too. So it's probably more profitable to shutdown the plant for repairs now, and restart production next year.

                                                                                                                                                                                      See how you noticing this problem started a chain of events that solved the problem? That's the power of markets - they can use the collective knowledge and intelligence of all the participants to solve a problem.

                                                                                                                                                                                    A passive house can have 10% the energy cost/use of a regular "code" house. Even off grid, this can immensely help in the size of your battery required.

                                                                                                                                                                                    • PaulDavisThe1st 2 years ago

                                                                                                                                                                                      As others have noted, passivhaus standards would help fix the "in the winter, homes use a lot more energy than they can generate" part of this. I've read of homes in Scandanavia that are heated by their inhabitants plus the output equivalent of a few candles. Not totally convinced by these stories, but they point the way: once you've got the carbon-reduced/free energy supply in place, work on massively (if possible) reducing how much of it you need.

                                                                                                                                                                                      We have an old adobe in the high desert, and it is so far from passivhaus as to be a joke. I'm fairly sure that if this was built to passivhaus standards, even our currently undersized array could handle the heating needs.

                                                                                                                                                                                      • twarge 2 years ago

That includes heating, cooling, hot water, and our two EVs. This is possible almost entirely because of the insulation.

                                                                                                                                                                                        We were generating a surplus, so we installed an electric clothes dryer, which seems to have balanced everything nicely.

                                                                                                                                                                                      • ajross 2 years ago

                                                                                                                                                                                        Is that the "fundamental" problem being solved, though? Or is it just an externality that needs to be addressed? It seems like the "fundamental" problem here is trying to maximize deployment of renewable generation, and that construction like this is a great step in that direction. (Not the least of which because it pushes the investment required onto consumers willing to bear the costs, and "generates jobs" in the process. Siting a new wind farm is a ton more complicated, and let's not even talk about the difficulty of installing a scratch-built reactor.)

                                                                                                                                                                                        I mean, it's true, that at the end of the day home energy generation is just PV solar, and PV solar doesn't behave like gas plants and that needs to be addressed at the grid level. But that's not an argument against PV solar, it's just an engineering problem.

                                                                                                                                                                                        • Syonyk 2 years ago

                                                                                                                                                                                          It can certainly be an argument against residential rooftop solar.

                                                                                                                                                                                          In general, "industrial solar" (ground mount, high voltage strings, single axis trackers) is sub-$1/W installed. Residential rooftop solar is still $2.50-$4/W depending on where you are, because it has quite a few additional requirements (per-panel rapid shutdown in NEC 2017, various other requirements on the panel and interconnects that add cost), and, often, poor siting from partial shading reasons (chimneys, vent stacks, trees, other bits of roof, etc).

                                                                                                                                                                                          I don't mind making homes more suited to solar (oversize the main busbar with a "solar ready" panel, route conduit up to the roof, require all vent stacks be on the north side of the roof), but it's a rather uncontrolled solution that's of limited "actually solving the problem" use. Low levels of penetration are easy to deal with, higher levels start to get really hard, when you've got whole subdivisions shifting from "lots of production" to "lots of consumption" as clouds go over.

                                                                                                                                                                                          Or, we get used to less reliable, more intermittent energy again, and a lot of the problems go away. Just, that generates other problems.

                                                                                                                                                                                          The power grid is a lot more fragile than most people assume.

So pick the low hanging fruit and sell it to the FAANG hippies. I still fail to see the problem here. No one is promoting rooftop solar as a one-stop-shop trip to renewable utopia, just as a effective and immediately deployable generation mechanism in a regulatory environment not well-suited to agile and rapid solutions of any kind.

                                                                                                                                                                                            If we get to the point where the hippies are buying up all the panels and the grid solutions can't get them cheap enough, that's the time to start complaining. Not now.

So long as this problem remains unsolved, no amount of supposedly zero energy homes will ever get the country as a whole to that goal because they're still reliant on selling excess energy to the remaining "non zero energy" parts of the country in the summer and buying energy back from fossil fuel plants in the winter.

Ergo... it shouldn't be deployed and we should whine about it on HN?

                                                                                                                                                                                                No, that's silly. Build the panels. Build the solar. Fix the externalities, but absolutely pick the low hanging fruit. Every panel on a hippie's home means less total joules needed elsewhere.

                                                                                                                                                                                                To be blunt: the kind of argumentation you engage in is absolutely toxic, and HN is awash in it. Engineers love to scream about perfect solutions, but real engineering is about tradeoffs. And folks here are absolutely terrible, just really, genuinely shit-tier, at discussing them rationally.

What kind of frame did you install to mount the panels? I have tons of room for ground mount and would love to do it diy as soon as the costs line up.

I have a solar power trailer for backup power.

                                                                                                                                                                                                https://www.sevarg.net/tag/solar2020/ documents the build. My frames are timber, though a neighbor built a very similar system with metal frames and 72 cell panels, and got his costs down quite a bit further - he's around $1/W installed, mine was somewhat higher at about $1.50/W (more expensive panels and a good bit more expensive frame setup).

                                                                                                                                                                                                If you can weld, and find used pipe to build your frames with, you should be able to do sub-$1/W for a DIY install.

I have my panels on metal structure with no welding, I used bolts for joins.

I'm assuming no one does this because batteries are likely cheaper than this type of setup.

Go do the math on it, but you'll find a 55 gallon drum of water, from "room temperature" to "really darn hot" holds 15-20kWh of energy. It's useful, but not a staggeringly large amount for a typical house, that can easily use more than that on a single day's heating.

                                                                                                                                                                                                        Thermal mass storage requires a lot of mass to do anything useful, or the ability to run exceedingly high temperatures. Or a phase change. Molten salt storage can store a lot of energy, but you're at "very hazardously hot" temperatures with "stuff that's mind-bogglingly corrosive when hazardously hot." It's not the sort of thing most people would want to mess with at home. Myself included, and my tolerance for experimentation is pretty darn high.

                                                                                                                                                                                                    • SamBam 2 years ago

It's fairly thin dirt on top of a lot of basalt. I've considered it, but the cost to install such a unit is quite staggering, before I buy a backhoe to install it.

                                                                                                                                                                                                            I'll consider one of those if I have to replace my unit at some point, but I'm far more interested in adding simple solar thermal collectors to directly add energy from the sun on the partly cloudy or clear days we have, vs ripping up half an acre of rock to put the loops in, or figuring out where I can punch another well for heat exchange.

                                                                                                                                                                                                          • G_z9 2 years ago

If your stacking up to 4mwh then your house is not really a good example.

There's plenty of wood waste floating around that could heat a small house/shed in the couple of winter months when the solar panels don't do the job.

The house has pulled an extra 4MWh from the grid during the winter months (and pushes more than that back during the rest of the year). I'm past net zero on an annual basis, but that doesn't mean that even a large array is able to cover my energy needs in the winter few months.

                                                                                                                                                                                                                  I'm grandfathered into an arrangement where I pay my $5/mo and get unlimited net metering, but it's not remotely reasonable to pretend that I'm not heavily using the grid overnight, in the winter, etc.

The maintenance costs of the grid are going no where but up. More usage, more right of way, more towers, more wire, more labor.

Obviously you can’t have an air-tight house for very long, you need fresh air. So you have explicit vents for incoming and outgoing air, and you run the incoming air (which is fresh, but not the temperature you want) through a heat exchanger with the outgoing air (which is stale, but is at the temperature you want). This recovers most of the heat you put into your inside air, so you need very little heating to maintain the desired temperature.

                                                                                                                                                                                                                    This is actually a really good thing, I think. The minimum airflow rating these houses have to meet is of course going to be suboptimal, but the hard part of airproofing is already done and it’s easy for the homeowner to simply beef up the heat exchanger and air pump to get ideal airflow. The homeowner can also install an air quality filter on the airpump and now their entire house has filtered air. Great way to get that PM2.5 level down to where it should be!

Many many places you can’t just have a sealed up system or you get mold immediately.

                                                                                                                                                                                                                    • s1artibartfast 2 years ago
                                                                                                                                                                                                                      This is a pet issue of mine, having lived in two off grid homes going back to the 80's.

                                                                                                                                                                                                                      The barriers are not materials, technology, or labor, but purely regulatory.

                                                                                                                                                                                                                      I could take my current home off permanently grid with solar today for less than 10k but to do so would be illegal.

                                                                                                                                                                                                                      Permitted grid connected solar costs 5x that and disconnecting from the grid is not permitted.

                                                                                                                                                                                                                      • aclatuts 2 years ago

What you get from paying the utilities is a team of people who will fix equipment issues due to failure or the environment. If your home battery system has issues, scheduling someone could take a day or more. Off grid electrical services isn't popular enough to be on call 24/7. And getting parts may get take even more time. Equipment failure could take your electricity out for days or weeks. Being fully off grind means over provisioning your electrical storage and production, adding to costs. You also would not be able to sell your excess electricity. Also, in terms of house value, I imagine more people value the peace of mind of a connected electrical grid over saving the small fixed monthly connection fee.

                                                                                                                                                                                                                          It's hard to get house insurance when you're not on the grid, and whenever they get asked about it, they ask the insurance person on the phone "When was the last time you had a power outage?" (inevitably the answer is sometime in the last month or three - the power grid in the Yukon is a fickle thing).

                                                                                                                                                                                                                          In 20 years, they've never had a single second of power outage in their very nice off grid house.

                                                                                                                                                                                                                          • s1artibartfast 2 years ago
                                                                                                                                                                                                                            I totally agree that it is not for everybody, but I think there is a place for it and think there should be fewer barriers .

                                                                                                                                                                                                                            I've seen a few people quoted more than 500K for PG&E to run power to their house. That can buy a lot of redundancy and peace of mind. Similarly, many cities have power outages longer than 24 hours on an annual basis in California. At this point most people in my neighborhood have gas generators for when the grid goes out.

I'm sure the local utility will stop service, which is what the home owner wants by going "off grid". But does it go beyond that? Will the local utility put a lien on the house? Will the local utility send any unpaid "fees" to collection? Does the local municipality condemn the property (or something similar)? Are there potential criminal charges?

Utilities serve the whole city, if you don't connect you are violating the unwritten agreement to help the city exist. Even if you don't use power you need to pay your share of the power lines.

                                                                                                                                                                                                                                  Before home generation, everyone needed both. The cost of the infrastructure was amortized over all of the customers. As it turned out, rich people used more power, so by having a single charge just based on usage but that covered the cost of both usage and the grid, rich people subsidized poor people.

                                                                                                                                                                                                                                  But the home solar came along, and the rich people started getting it. So now the power companies have a problem. They still have to maintain all of that grid infrastructure, whether you're connected to it or not, and they need rich people to subsidize it.

You can certainly build houses in the US that aren't on the electrical grid, demonstrating that there's no federal prohibition against it.

If your home is already connected to the grid, then I would think the ongoing cost would be minimal and could be viewed as just another tax.

Everything still needs to be inspected and permitted to the same level of rigor because it is still technically wired to the grid and you just have more elements which could malfunction in a less standard configuration

Ignore the grid connection and just treat the monthly service charge as another tax.

                                                                                                                                                                                                                                      Or if you can get away with having a power inlet on your off grid system and powering that system from the grid with an extension cord during temporary backup/maintenance conditions only, go for that.

                                                                                                                                                                                                                                      For my own AHJ, grid interconnect has nothing to do with whether permits/licenses are required (and for homeowner work, they're not). So an off-grid system and grid-connected are under the same requirements there regardless. A grid-tie system that can feed back power to the grid requires additional signoff/agreement with the POCO though.

                                                                                                                                                                                                                                      (I'm very sympathetic to the situations where the utility will demand some stiff fee to build out a grid connection to a new residence, while local regulations require this connection for occupancy. But this isn't what you described)

The code changes over time and governs all kinds of mundane things that you as a homeowner don't pay attention to (and shouldn't be forced to). Not being compliant doesn't make a home illegal to live in.

Many municipalities specifically require all dwellings to have basic utilities (water, sewer, electricity, garbage service), even if you're not using them. Not having that will get you in trouble pretty quickly.

                                                                                                                                                                                                                                          Disconnecting from the grid - that sounds like there's some kind of clause in the area that you live that essentially ties you to the utility. You must live in on the pacific coast or SW.

                                                                                                                                                                                                                                          EDIT: To all the responses - I'm talking off grid as in all functionality. Sure you can add solar / solar thermal etc though in many places it isn't cost effective and doesn't make a lot of sense in a city where the alternative is that those costs are defrayed across a large base that provides reliability and service. I don't have much love for utilities but they do provide a valuable service.

It is a scam, considering most people did not have electricity even 100 years ago.

Sewer and water are the main problems in an urban environment. Rooftop solar on the other hand is dirt cheap and only slightly more complicated to install then plugging in a toaster.

And typically requires an electric service upgrade - you also need to make sure you aren't near the end of your roof life as you'll need to upgrade your roof as well.

You can get 10kwh of lead acid batteries for another 2 grand, a 10kw combo MPPT for ~1 grand or a 10KW charge controller + 5 KW AC inverter for the same.

Constant low humidity is really unhealthy. Without them these ultra insulated homes have major vapor and mold issues. Being highly insulated is good but at a point it's just silly. I'd rather see efforts to insulate old trailers, manufactured homes, etc. Rich people experimenting with zero energy homes don't need a credit.

I'm only familiar with cold climates, so perhaps I'm overlooking something, but mold needs moisture to grow, so it will appear where water condenses out of warm air on a cold surface. You can typically see this in windows.

                                                                                                                                                                                                                                                      So you need to prevent cold surfaces. The best way to do that is improving the insulation. The reason you can see water drops in the windows is precisely because they are inadequately insulated (e.g. only double paned).

                                                                                                                                                                                                                                                      Now, it's true that if you make an airtight home, then you need some kind of air exchange. And if it's really cold outside, then even if it's wet, once that air is warmed up, it ends up at a low relative humidity. In that case you need a humidifier. I guess depending on the outside air, you'd probably need both to stay in a comfortable range.

                                                                                                                                                                                                                                                      • paiute 2 years ago

Water vapor "wants" to equalize from a more humid to less humid environment. So when it's cold out - the humidity can drop rather low. Then you take a shower and create water vapor - which flows into the walls, through the insulation, and condenses against the colder exterior. Open a wall in any stick frame house in the rocky mountain region and mildew will be present. I am building a highly insulated house in a cold climate area and have blasted all the wood with copious amount of a silver based coating to inhibit mold growth.

The standard solution (for > 25 years) where I live is that you install a vapor barrier (plastic) to prevent the moisture from diffusing outwards. It needs to be on the interior side of the insulation in a cold climate.

                                                                                                                                                                                                                                                          Edit: Sorry, I can see that you're aware of these. Perhaps my point is just that all standard houses where I live in cold climate uses vapor barriers. Moisture control is part of the building code. Trying to solve the problem with overly dry air does not make sense to me - the whole point of a house is making a comfortable living space.

You can't just build a super insulated home without great ventilation. And obviously for energy efficiency you need heat exchangers between in/out air (Alternatively as a slightly cheaper and easier to retrofit option, a heat recovery in your heating system such as an exhaust air heat pump). Maintaining good humidity in any weather also isn't very difficult.

                                                                                                                                                                                                                                                            I agree subsidizing new homes doesn't seem necessary. This is simple to enforce in building codes. Defined efficiency limits for construction and building components (e.g. requiring triple glazing and 12in insulation in all walls) would be trivial to mandate and it's as reasonable in Florida as it is in Maine.

The student residence hall[0] there is built following Passive House standards and it is actually surprising how good it works. My one complaint is the heating and cooling systems in every apartment unit are very heavily regulated, so at times the inside feel and temperature aren't ideal. It's a minor thing though.

But not all Passiv Haus designs are necessarily Net Zero, and not all Net Zero designs necessarily use Passiv Haus to accomplish their rating.

But they're also tricky to operate properly.

There's a lot of energy upgrades that pay off well over a couple decades, but not when you move an average of every 7 years and the new homeowners don't know how or care to value your upgrades.

                                                                                                                                                                                                                                                                        I think the government could create regulation to fix the incentives here. Something like allowing enhanced energy efficiency to be paid over time by creating a lien on the house that a new homeowner has to continue to make payments towards.

                                                                                                                                                                                                                                                                        • la64710 2 years ago

Just from an incentive pov is it enough to swing the needle? Most probably I am glossing over something.

In theory, having this cert should raise the value of the house. I view the $5k as a way to offset the cost of applying.

You're probably already going to insulate because it pays for itself. The tax credit makes it possible to go the extra mile.

So I followed a link, that led me to this definition:

What is a 'high-performance home'? And what exactly is the criterium to decide if 'a renewable energy system could offset most or all the home's annual energy use'?

Double pane windows are well-surpassed by those with many panes and carefully designed frames with low thermal bridging. Aside from more insulation you need great air sealing, across every joint and in every window and door frame. Older construction had no explicit ventilation, just a lot of leaking such that the house "breathed". On modern, efficient homes, the air seal is very tight for efficiency reasons, so you need an ERV/HRV system to exhange air for you to keep the air healthy, while minimizing energy loss for that airflow. Insulating materials used inside the roof and sheathing are typically closed cell foam or rockwool, or in Europe they sometimes use a wood fiber based insulation. There are lots of caulks and adhesive tapes for getting a good air seal, and there's also a technique where one pumps the house frame full of a vapor that reacts across pressure drops and plugs any holes it flows through.

                                                                                                                                                                                                                                                                                    Last, well insulated homes can get cheap heating and cooling from modestly sized heat pumps which are very efficient. One zero energy home I saw has heat exchangers on the roof to capture energy from the sun for warm water as well, supplemented by heat pumps powered by photovoltaics.

Then the put 2 inches of foam under the siding so the thickness is equal to a 2x6. There is already on the market standard doors and windows that fit this. Though 4 inches of foam may make more sense yet, but there are no standard doors or windows for that thickness so costs go up.

Engineers started to factor in the insulation value of a 2x6 compared to the insulation it was next to and the heat loss in cold climates. Same applies for hot climates. Now these homes are being wrapped in insulation on the outside with all joints sealed, then insulated on the inside and essentially pressure tested for air leaks. The houses can be "tight" enough that you have to have a system to cycle in fresh air in a way that it heats/cools it with the air that is leaving. You also need a makeup air vent for things like a stove hood.

                                                                                                                                                                                                                                                                                      There is a new system that before drywall goes up, they pressurize the house and spray a caulk in the air that finds its way to all the pinhole leaks and seals them to further reduce air leaks during the building process.

Houses are unlikely to be so drafty that the air inside is always fresh, and a real ventilation system will deliver fresh, filtered air all the time.

Sadly, high end hoods seem to mostly have way too much airflow, and decent makeup air systems are rare and complex.

They are used to pre-heat the makeup air. I'm looking into one atm as part of a HVAC upgrade as currently running a bath fan with all the windows closed will draw air down the chimney.

You have to competently install sheets of rigid insulation, and then you need to competently install siding over it.

Or you can use some kind of blown in product, which takes very little labor. (I have never seen competently installed fiberglass batts. I’m not sure they really exist.)

Go around all over the house with a smoke gun?

You don't need to survey every inch though since leaks aren't present in the middle of walls, but typically at complex areas (around windows, roof penetrations, can lights, outlets, rim joists, etc) so a little smoke quickly IDs those issue areas. Another way way to find leaks is to run the blower door tests on a day where there's a large temperature differential (ideally when it's very cold outside). You can use a thermal camera before the test and then after you depressurize the house for a 10 or 15 minutes - the leaky areas are perfectly obvious on the thermal since the cold outdoor air is washing over the walls near the leaks. Taking the before/during thermal videos on a walkthrough lets you compare the side-by-side later on and ID which spots need attention.

It looks like the homeowner can get a $5000 tax credit for 10 years.

To that end there are requirements for the thermal integrity of the envelope and windows, there must be electric run for HVAC heat pumps, hot water heat pumps, and at least one EV parking space. Lighting must be modern high efficiency stuff. Ductwork must be inside the thermal envelope. There are indoor air quality standards to meet.

The 2015 ICC isn't a slouch either -- say you're in Chicagoland building a new home, this would mandate R49 in the attic, R20 in the walls (or R13 in the bays + R5 exterior), R15 on basement walls, R30 in the floors.

                                                                                                                                                                                                                                                                                                        It could of course be much more aggressive, and likely will be eventually, but if you had a ACH2 house with those insulation values, minimum U-0.3 windows, >0.94 efficient gas furnace / high quality heat pumps, it would be a very efficient house.

It's such a dumb unit of measurement. We already have a base unit of energy, which is Joules. Dividing J by seconds to get W and then multiplying that by hours to get franken-joules is so unnecessary and makes the math harder for no reason and it makes me mad every time I deal with it.

Wood is a very, very bad heat insulator.

Granted, you cannot build a macmansion-like house using only earth+some wood.

You have to be careful not to allow water infiltrations, but other than that those houses are pretty durable, even against earthquakes (my grandpa from my mother's side used to live in one).

Part of that is because it’s hard to learn news things. Part of it is because new things have lots of unknown and builders shoulder that risk.

It's better if houses were built to not depend on volatile energy prices. Net zero homes basically move the monthly utility cost from an ongoing variable bill and basically prepays it into the mortgage which would have more predicable pricing.

But this is similar to the gas -> electric car change. Yeah, it's a marginal improvement on what we're doing now, but its so far away from the kind of changes we need to make that it's almost dispiriting to see it presented as some kind of remarkable progress.

Blown-in cellulose is "advanced," huh?

                                                                                                                                                                                                                                                                                                                                                            It doesn't answer any of the specific questions about what's specifically different in a Zero Energy Ready Home from something Energy Star rated, and it's filled with weasel words and vague handwaving statements.

                                                                                                                                                                                                                                                                                                                                                            I could nitpick the response further against the actual PDF linked elsewhere in the thread, but there's no particular point.
