Air circulation in an old summer cottage
We have a 1899 summer cottage in New England. In our area it is cool at night outside but super hot inside particularly upstairs. We are so vexed by this. I am trying to figure out a way that we can avoid getting AC.
The cottage has a small foot print and 3 small bedrooms on the second floor. The bedrooms have small windows and surround a center stair. There is a 2-3 foot high attic with windows on either end. The bedrooms have sloped ceilings (eaves?) and the windows are nestled under the eaves . We have a hatch we can open to the attic over the stair well. It is not winterized.
What happens when we open the hatch and the attic windows is that the cool outside air is sucked in from the attic through the downstairs windows up the stairwell and out the attic. The bedrooms remain airless, hot, and stagnant. We also have an attic fan, but the problem remains. Arghhh!
Does anyone have any ideas for us. We have asked local professionals,, but nobody seems to get the nuance of the problems (ie. the center stair well directs the cool air out through the attic).
Some of our ideas include putting in bigger windows in the bedrooms (a big Reno project for us which we are reluctant to do right now for financial reasons). Cutting holes in the bedroom ceilings and adding a register to try to get the air flowing out of the rooms. Adding fans in those holes for each bedroom.
We are a little nervous to start cutting holes until we are sure we won't make things worse.
I would love any feed back,
