Double-hung virtues
So far this summer is STRICTLY AVERAGE, which is a good thing. Most days are 55/85 with a few 90s and a couple 100s. Average days allow me to minimize use of the air conditioner by opening windows during the 55 part and using the AC during the 85 part.
Last winter I had a new front door installed, which helped some in winter. Definitely better insulation than the old door. It's less advantageous in summer.
Picture I took in winter:
The old screen door opened from the bottom; new opens from the top. Doesn't matter in winter when it stays closed anyway, but it turns out to be a poor source of 55 air in the summer. The top opening lets out warm air but doesn't let in cool air.
I can tell the difference by opening the entire door. With the screen open the room doesn't cool much. When the entire door is open even a few inches, the room cools IMMEDIATELY.
The double-hung sash is nearly obsolete now, and its purpose is forgotten.
Forgot or not, the purpose is still valid. Cool comes in below, hot goes out above.
