        My house was built with vents, un-closable, always venting vents. Inside temperature equals outside air temperature plus a little draft as the air moves from inside to outside and outside to inside

        Heating or cooling is economically impractical, except in two rooms, one with no vent and one with a vent blocked with foil

        I look forward to a knock down/rebuild where the future house will be will insulated and will exchange air with the outside in measured, heat exchanged doses and solar powered air con can heat or cool the house in peak solar generation and the house will be pleasant the rest of the day and night. I’m comfortable in 18°C to about 26° in winter and a little offset upwards in summer, and it’s pretty easy to build to not gain or lose more than 8° in 18 hours in my climate (lows in the single digit negatives Celcius; highs seldom more than 40°C)

        Not gonna do shit at night.

        I bought a battery for mine but you’re about to find how just how much power your AC system uses.

            In relation to how much power you’re going to make.

            Are you buying batteries? Unless you’re buying a whole lot of them ($$$) you’re not even making it one night running your AC like that.

            I spent $10k on a whole home battery and it got me 1/3 of my average daily power use.

            I stress average because summers were double that, sometimes 2.6x.

              I don’t know where you are from, but I’ve been to the US a couple of times and I can understand why the AC power bill can be absurd there. You cannot keep, in August, in the middle of the desert, AC at 18°C when outside there are 35-40°C. It’s criminal on so many levels.

              I had a layover in Atlanta last summer and I got home sick, so much was the air conditioning in the airport and in shops and restaurants. Outside it was proper sweating hot, inside I was freezing while wearing a hoodie. I’ve been on a bus where the driver was wearing a heavy jacket, in August, and all because the bus AC was set to something like 15°C. What is wrong with Americans?

              Keep AC at 25-27°C, remove all blankets and clothes when you go to sleep, and I bet you it will consume a lot less energy. Unless you live in the Death Valley, in which case, good luck.

                Yup, could do this. Have tried to do this. Slept like shit. Not worth it. I’ll spend the extra $50/mo on cranking the AC to wake up each day feeling decent.

                This was in west Texas so yeah, basically desert.

                I fully agree - every thread like this has people coming out of the woodwork claiming they’d simply die if their house isn’t =< 65f. Maybe it’s because we’re so fat?

                25c/77f is a perfectly reasonable temperature to have your house at. If I lived alone, it’d be 78 in the summer.

                  I live in a basement so it stays a little cooler but I was sitting at 77ish all summer last year with the Windows open and AC vents closed. I have never been so comfortable. Before I did that my housemates were freezing me out with the AC. I was walking around in a sweatshirt when it was 95 outside. Coincidentally both of them are overweight.

              Good thing you have a sun for most of the other 2/3.

                Have you even looked at the power curve of solar system output? You’re being obtuse.

                Plus you seem to have completely ignored the last portion of my comment.

                I rarely had months where I zeroed out my bill since I was in an area where credits weren’t a thing. My overproduction was sold back at ~$0.03 per kWh. I had to buy at ~$0.12.

                You can be snarky if you like. You’re still wrong if you think that’s enough to cover summer days.
