Generally speaking a house has 4 outside walls. The house has hot spots and cold spots. The coolest part of a home are the closets having an outside wall, better yet in a corner of a room having 2 outside walls. Our master bedroom closet is at least 6-7 degrees cooler than the bedroom itself as long as the doors are shut. Floors are another cool spot.
My bows and archery gear are in the basement.
