Hey! I realized that I pretty much only talked about the residential side of things and left some of the tactics commercial buildings use until the very end. Well, here’s me now saying that this is by no means something we can’t apply wherever it would work. In fact, many commercial buildings are doing pre-cooling already when it makes sense for them. None of the ideas presented here are new, exactly. But I do think there’s a lot of potential here specifically when it comes to getting use out of renewables. “Make hay while the sun is shining” is a perfect expression, here. In some areas we’re already running into issues where there’s so much solar capacity that we can’t use it all. Rather than wait until we have more electrochemical batteries at our disposal, perhaps we can use all this thermal mass we have. The key thing about insulation is that it slows the transfer of heat. That means it buys you time. The challenge of renewables has always been that the time of production doesn’t match the time of consumption, but with more intelligent control and awareness of a building’s thermal capacity, ability to pre-heat and pre-cool, and the tolerances of its occupants we have a pretty flexible tool for shifting consumption right now.

@mishaproduction 2 роки тому

@varno 2 роки тому

There is only one problem that I can see with this. That is that the rate of heat transfer is proportional to the difference between indoors and outdoors. This means that over cooling at night can make power consumption go up.

@TechnologyConnections 2 роки тому

@nebuchadnedzzar to be clear I do it at night because I don't have any solar output that I can take advantage of, and there's not much of it on our grid yet. Overcooling at night is what _I'm_ doing, but it's not where I'm suggesting we go with this. (edit to add): The other thing to consider is that if I run my air conditioner when it's really hot outside, the higher condensing temperature of the refrigerant makes it work harder. I'd need to do some experimenting to confirm this, but if the total amount of energy I'm pulling out with my cool-only-at-night strategy were equal to keeping the thermostat at a constant, say, 70 or 72, I think it would actually take more electrical energy. A larger load on an air conditioner makes its energy consumption go up, though not necessarily drastically.

@Tuskly 7 місяців тому

An example of how dramatically your house's insulation could affect how quickly your house keeps in the cold/heat is the work cup I used for work. I started out using a big 1 gallon plastic water bottle (good quality) and would prefill it with ice all the way to the top then top it off with ice cold water.... By lunch time 4 hours later my ice would all be melted and the water luke warm/barely cold. It was never in direct sunlight btw. THEN I upgraded and got a 1.5L metal water bottle (I think eddie bauer) good quality but still cheap. I would prefill with ice and then by lunch even in 100+ weather it would still be filled with ice... I'd drink all the water (2 bottles worth) then refill it multiple times (6 bottles worth after the original filling) and it would STILL have ice by the end of the 10 hour day. Just thought I'd rant about that to let people know how effective precooling could be on a well ventilated house vs one that's not. My house would literally take 3 hours to go from 90 to 76 but at the same time would go from 78 to 85 within an hour of turning off the air.

@conquerncam 5 місяців тому

We started doing this over a decade ago. As an 'adventurous' individual (and in the HVAC industry...) I was browsing through our utility providers website looking at rate plans. They never advertised it, but had time of use available for residential customers. The account rep told me that the people that would benefit from it usually are the ones that go looking for it to begin with. Our TOU is fixed in the afternoon. The thermostat runs at 72 most of the day but two hours before TOU, it drops to 67 and then to 80 once TOU kicks in. After ten plus years, it's just a way of life. Now, the concept has been marketed for a few years with utility tstats available to adjust automatically.

A friend was rebuilding a greenhouse that originally had a 2'6" brick wall with the glass structure built on top of the wall. He then bought a second hand aluminium frame greenhouse that fortuitously fitted over the brick wall, leaving a four inch gap between the wall and the glass. This wall made a great heat storage device. It made for a really good passive heater. At its location in the UK I estimate that my friend gained almost two months growing time in this greenhouse without any extra heating. The brick walls heated up in the day and radiated heat at night, it had automatically opening roof windows that used the expansion of wax in sealed tubes to open them. He was able to produce very good crops of tomatoes, chillis and other vegetables.

@stormthrush37 8 місяців тому

This is such a great idea and I love it. Personally the idea I've been playing around with that's very similar to ice storage air conditioning but takes advantage of close to effectively free energy is a big thermal mass likely in the form of a good sized well-insulated container of water and having the water cycle through a big exposed loop during the coolest hours of the night to cool the water down and then store that cool (negative) energy, and then cycling the water through a similar loop inside the house to cool and overcool the tank of water and house as needed. This could be done as a closed loop in more humid environments and/or where the water can't be replaced easily and cheaply and as evaporative cooling in dryer climates when the water can be easily replaced. This system could also probably be used in reverse to help keep a house warm in winter especially at night by heating the water up during the hottest parts of the day and having it cycle through the house as needed especially at night, heating and overheating the water tank and house a bit during the hottest part of the day. Like the recent return idea of putting sails on massive cargo ships this method wouldn't even have to provide all the heating and cooling for a house; simply offsetting the energy usage would be a big help especially since the materials costs of such a system would be so low and thus the length of time for the system to pay for itself would be so short. All you're really talking about materials wise is insulation, the water tank, the lengths of narrow copper or other piping, and some sort of pump to move to water. You could also power the pump with solar or another renewable if you wanted to reduce conventional energy usage to nothing. You could probably simplify this idea further by using a big water heater; it's already insulated and has the basic piping and thermometers and thermostats installed.

Great video. I learned that most water heaters have two thermostats with heating elements. One set is near the bottom where cold water enters and the other is near the top where hot water exits. They are usually set to the same temperature but I thought this could be manipulated to store solar hot water. The water heater would have the standard switch between grid power at night and solar power during daylight. The top thermostat would be set to 120 degrees and the bottom would be set to 140 This means when the bottom heating element is on, the upper element would not come on and the water in the tank would be superheated. The trick would be to put a timer on the bottom switch so it is only active during daylight hours This means that the water would be superheated to 140 degrees when the sun is up and only 120 degrees when using grid power. If the power company offers off-peak rates, the lower element could come on during off-peak hours to top off the water when power is relatively cheap There are problems such as intermittent low solar power availability during daylight hours and changes in sunrise and sunset times throughout the year. A simple system might have to brush over these issues and not be perfect but I could see a more complex programmed timer controlling the lower element that takes into account solar power availability

I'm in the PNW and we have a couple strategies in our very old house. 1. Over the biggest windows, there's an arbor with grape vines-- this means no leaves in the winter, and plenty of shade in the summer. 2. The temp differential here during the dry summer months is such that most of the summer, we can just open everything up at night, let the breeze cool the house, and close it up in the morning, keeping the heat out for the rest of the day. 3. During the winter, we never have the thermostat over 65, but use a lot of blankets and sweaters and hoodies. We don't have peak pricing for energy here, because it's mostly hydropower/wind/solar, so at night we turn it down to 60. 4. Rather than cooling the whole house, we air condition the south-west facing bedroom. I put it on eco when I leave the room, and it gets up to about 78, and then put it on auto cool at night as soon as I'm up there, The room stays tolerable, I can deal with the rest of the house being warm, and it doesn't usually get that warm. During massive heat waves, this means we have a comfortable place to take heat breaks, but are air conditioning a huge old house.

Another trick i use is this house had an attic fan installed (built in 1970) before the owner installed HVAC.

That was the concept of an electric heating accumulator too. More or less. An accumulator has some bricks in an insulated box. Through the bricks, there's an electrical heating element, capable of heating the bricks to 700ºC. Then there are vents (and a fan) you can open to dump that heat into your house. As the accumulator is insulated, it works a tad better on badly insulated houses than trying to store the energy directly in your house. But these things have many disadvantages: a suboptimal efficiency (some heat is lost when you don't need it), and the high temperature means heat pumps don't work. They're also bulky to install in your house, and when the fan comes on, they make a lot of noise. So they've generally fallen out of favor.

Running AC at night would also be more efficient in general too wouldn't it? With lower temps outside it would be easier for the condenser to reject heat.

@joshmiller7870 2 роки тому

Yes. Only no answers would be if it were cold cold. In ambient temperatures drop to 40⁰ and lower most residential aircons run into problems (unless its a heat pump in heating mode ofcourse👍) and damage your compressor. Its called "slugging a compressor " funny name. Basically what happens is this: Compressor is made to pump gas/vapor, so, if temp drops low enough to cause the heat in the low pressure gas to leave fast it will condense into a liquid. This is bad news since liquid doesn't compress. When liquid enters the compression area (could be a piston, scroll, or rotary type), it damages the parts that do the compressing and eventually crumble those parts into chips and chunks. Fun fact. To get around this happening in Commercial applications they toggle the condenser fan via pressure switch in refrigerant line. Also the put this giant hose clamp around the bottom of the compressor that is a heating element that warms the compressor and oil to a good operating temperature in low ambient conditions.

Back in the 90’s (in Europe) my parents had a device which was basically an insulated box with around 300 kg of fire bricks inside. Those bricks were heated by a resistor over the night, when power was cheap. During the day, an air flow was created through this volume with a ventilator and vents in the box. We could heat our 90’s insulating standards house with this.

That's the joy of rammed earth houses. The fundamental idea is that you make your house such an enormous thermal battery that it cycles on a timescale of about a year. The most comfortable house I've ever worked on had an Ancient-Roman style open sky courtyard and garden, with passive rainwater collection due to the sloping of the roof, and the only offshoots that had any thermal management were the bedrooms with thermal pumps that tied into the garden rainwater resevoir. The kitchen just had a masive hood vent to dump the hot air, and would draw cool air from the rest of the house. I think the most they ever paid for electricity over a month was $60.

@alpacagurl92 Рік тому

Timescale of a year? that's literally one of the silliest things I've ever heard. Rule of thumb for earth insulation is that heat transmission is delayed by about 8-9 hours per foot thickness of earthen walls. How do you expect to get a year cycle? Even the great lakes in Michigan don't hold thermal energy that long. I think you're misremembering that earthen houses cycle on the timescale of day, which still greatly reduces cooling and heating costs without your house being freezing in the morning.

Our house was built in 1951. When we bought it 25 years ago it still had the original single pane wood windows that swelled/shrank, leaked air, sweat and frosted over in the winter. About 5 or 6 years after we bought it, we had all new double pane low E windows put in. Also about 6 or 7 years ago the air conditioner started having issues, so we had a new high efficiency furnace and AC unit installed. We have also put in all new entry doors (3) and insulated garage doors. We've spent well over $25,000 to save energy/money. Also, we had a new roof put on last year because our old one was worn out and needing replaced, but we spent extra money to put on a roof that is supposed to help with energy savings. It takes a long time to make that kind of money back in energy savings. I'm pretty sure that we may never break even. We could have spent more money, for even more "savings", but I don't know how much more "money" we can afford to save. A lot (I would bet that most) people living in older houses can't afford the expense of retrofitting their houses to bring them up to modern day energy standards.

61% of Americans live paycheck to paycheck, so yes, a majority of Americans don't have any capital for improvements. I kept thinking about my mom's single-wide trailer and that even if I had the money for improvements, it seems really silly to pull the whole thing apart to add insulation. Would probably be better to add a vertical wind turbine on top and call it a day. And my 7th-floor apartment with a wobbly sliding door to the balcony isn't doing me any favors. At least heat pumps are standard on the building.

I held on to my old faithful oil boiler (home heating) for years, and I love it...but the price of home heating oil keeps rising and the new bio diesels have not been cheaper or accessible. The extra yearly expense for oil means that I will see a return on my investment in a few years.

He buried it in his backyard and plumbed his house HVAC air ducts into it. At night, when the utility company incentivized peak demand at night with super low rates, he was freezing water in his buried freezer. During the day, when it was 115F outside, he was melting ice by cycling house air through it to that kept his house at 60F. It paid for itself in a year or two. All homes should have such a system.
