- joezydeco 2y agoYou mean, like a greenhouse?
- tonyarkles 2y agoWe have an older mobile home on a rural lot in the middle of nowhere, and by far one of the best quality of life improvements we’ve made to it is awnings that were designed to let the sun in during the winter but not in the summer. In the winter we keep the furnace set at about 68F there during the day (65F at night) and on good sunny days it can be -20F outside and up to 73F or 74F in the living room! In the summer without running the AC it would get up to 85-90F in there while only 70F outside… with the awnings we barely need the air conditioner most of the time. Still do on days when the outside air temperate is oppressive, but the place isn’t a greenhouse all summer!
