Average quality built homes needing makeup air because they are airtight
I have a question in regards to homes being built (not necessarily green homes) that are subject to the new energy code with air sealing and blower door tests. These homes are being built with average, code minimum building materials and after a blower door test it is showing the house is tight enough to require make up air.
Seeing as these are not green homes, there was no plan in place ahead of time for a system to bring fresh air into the house. Are you seeing this as a problem in other states as well?
I am in CT and a friend of mine building a house just dealt with this issue with his local building official.
What is the option for bringing in fresh air when you learn you need it at the end of your build? As I am looking to build in the near future I assume I will be running into this as well. In the example of my friend’s house, it is constructed with 2×6 walls, 1/2″ zip system sheathing, roxul batts in the walls. It is a cape style home.
