Summer is the "green" season. The days are long, with sunset well past 7pm. The nights cool off (most of the time). We start the day by closing windows to keep out the heat. We end the day opening windows and turning on fans to make it comfortable for sleeping. The earth part of the earth-sheltered house does it's job by insulating the living areas from the day's heat. The castle-tower part of the house - not so much. But where ever you are, oh the views.
