Case study of an improperly designed energy retrofit project where airtight windows and other measures were taken without an integrated approach. The failure to upgrade the building envelope resulted in mold formation due to persistent condensation inside the building walls & ceilings.
An image is worth a thousand words.
In our previous articles, we have cautioned that an energy retrofit should be approached with an integrated, whole-building approach, and by a professional with experience in calculating and simulating thermal envelopes.
The photos below show what happened to one family’s home when they decided to do an independent partial energy retrofit, without consulting a qualified professional. In this case, they decided to replace the old windows of their house with newer, high performance windows, hoping that they would be able to reduce their energy consumption.
These photographs are courtesy of our friend and colleague Damiano Chiarini of Studio Rinnova, who joins us in emphasizing the importance of an integrated approach to energy retrofits in order to avoid disasters like this one. He was called in to consult the building owner on possible solutions after this attempt to upgrade the…
