humblebee hive – retrofit #7

Seal tight, Ventilate right It’s the retrofit mantra. And we did notice how quickly it got stuffy once the windows were in and the EWI was all but sealed. We were still getting chilly inside, in part because in order to have fresh air we had to have the windows open, while the rest of the...
