Had a sun setter awning on my house in Becker, MN. It didn't do much to cool off the house, but it did make the deck very pleasant. I suppose that it would be a major factor of where the awning is, the relative position of the sun during the daytime, and how big your house is.
Small, very small but there is just the 2 of us and the pets.
Perhaps 1,200 sq foot, we have 2 unused bedrooms that we forget about, turned into junk rooms actually. Now that I have nerve problems and have a problem standing and walking I find we have too much house to care for, we still have 2 full baths, family room, laundry room, living and dining room and a good size kitchen and the master bedroom. Way too much space for just 2 people.
When we bought our home the seller was an American Indian ---Micmac I believe and the house faces the north west. Kind of strange as all others face west.
We have noticed that there is less storm damage due to high winds then our neighbors. We have lost a few shingles but not to the extent we see from the other homes.
Come summer the sun coming from the east moving into the south heats up the deck and as it[ the sun ] moves around to the front we get the full heat of the day on the front of half the house.
Really odd about our location, we had 3 years ago one of those so called Ionic Bursts, took down trees, sent them into neighbors windows and roofs. Heck of a storm, some homes were actually moved of their foundations. Homes on both sides of us had great damage, we had just one loose shingle, All houses that got the brunt of the storm faced west yet for some reason tracking the damage down the highway it ran in a East pattern.
Screwy if you ask me. They ruled out a tornado, so no one to this day really knows how or why this happend.
We had a cheapo awning on the deck for a few years, took down in the fall, put up in the spring and it did with the help of ceiling fans keep the house cool enough so we did not sweat allot. Before we could get it down last fall a big wind with mega-rain came up and tore the thing apart. We could not believe it, neighbors with the same awning had no problem with theirs so I have to put the fault on poor Hubby who did not install it correctly that year.
New homes built today in this area have overhangs from the body of the home over the windows, they block the sun in summer and when the sun is low in the sky in the winter allow light and heat in.
