about 40 years ago , the houses that were built in tehran were all facing south, the south side of rosh hashir. they put it on the front side of the window so that the heat of the sun does not come in, but now no one cares because now there is an air conditioner, until 40 years ago, at night, everyone went to sleep behind the bowen because it was hot inside the room at night, but now you turn on the lights inside the house at night, so now that climate is no longer as important as it was in the past. the high level of building and the speed of construction without considering the basis of green architecture caused the identity of architectural sports to be ignored, including attention to the climate. i myself used to design the building in tehran for winter until 30-40 years ago, but now i want to i will design a building in tehran . i will design it for the summer. it has been 20 years since the cooler the water is slowly collecting and replacing it with a gas conditioner. now, a 100-meter apartment in semestan costs 80 tomans a month for gas. we have to pay 300,400,000 tomans because of that
