Forum Title: Blower Door Test On Additions
I'm a new builder in Michigan and I had a question about blower door tests. I know that additions must meet the energy code but unaltered portions generally do not. Are blower door tests then required on additions? If you take out a large section of external wall to build the addition is the blower door test possible and would it even make sense?
