To freeze or not to freeze
I have a current client who wants to turn heat off to there summer lake house every year from November to April. The house is in the process of being built right now. It is a high efficiently Vermont certified house when completed. My question is whether the little bit of saved propane fuel is worth freezing the house or not? What long term impacts can happen with these types of homes with this much insulation and air tightness? My fear is that solar gain into the house could create dew moisture, and also further push the dew point into the interior leading to drywall mold over the next few years. It has 2 inches of continuous foam on the outside with r-40 walls and r-60 attic… with blown in for both. Are these homes resilient enough for this? Thanks you in advance for your thoughts.
