I really wanted to thank everyone for participating in this discussion. It's a topic i am very interested in exploring.
Where I live in the desert Southwest, people have lived for thousands of years without AC. From studying their living choices, architectural features and chosen home locations, I don't think they suffered greatly from the heat. The peoples lived in river valleys, within shaded rock alcoves and within thick cool insulated adobe walls with excellent cross breeze placement.
They had water filled earthen pots places in hot doorways to make a swamp cooler effect. They cooked outside. They took cold dips in the streams. They would lie low in the hottest hours and work hard in the cool mornings and evenings. None of this sounds terrible to me.
In our society, every summer people die of hyperthermia in uncooled apartments. I can't help but think we are doing it wrong.
In any case, all this is my disclaimer about tomorrow. It's supposed to be 102. I really hope to NOT turn the AC on yet. I was thinking it wouldn't be that hot until late june. This has been a record setting heat month.
It seems to stay cool enough with my techniques until 2-5pm, when all the leftover night coolness seems to be totally replaced with hot air from outside.
I actually will be out of the house by 2:30pm, so this might work fine for me. I won't be back until 9pm or so. One of my techniques is avoiding the heat entirely. This isn't cheating. If it was good enough for the Anasazi and Sinagua peoples, it's good enough for me.
Anyway, here's the total plan - windows open all night with fans blowing cool air inside. Shades open. Door open. In the AM shut the door, shut all windows but the ones I crack with a fan to keep a cross breeze going. Shades shut.
Do not cook inside. The coffee pot and hot plate are on the patio.
Lights off unless I am doing something that requires task lighting. No incandescent (heat-making) bulbs ever.
No hot showers that will create indoor heat. A cool afternoon shower is always lovely when it gets warm. I can use cold washcloths from my freezer for my neck if i need to, and if i go outside. There is a fan at my desk that blows across my face.
Drink lots of cool water.
I am also thinking to wet down a sheet and hang it over the window i have my fan in, to create a free evaporative swamp cooler effect. I can try adding more wet towels to my desk area and see if that helps too.
Okay. This is my plan. I will report! Remember, I hate being hot and melty. I am not some special Amazon woman who shrugs off the heat!
