Passive House in the Woods, Smoke Test

Testing for leaks with smoke

With the help of Gary Nelson of the Energy Conservatory in Minneapolis, we were able to conduct a first series of blower door tests. We pressurized and depressurized the building, and used a smoke generator to identify leaks. This was an amazing process and helped us gain a great deal of understanding for the little details that make a building air-tight. In the end, the building delivered an average of 0.36 ACH50. We are excited to have surpassed the Passive House requirement of 0.6 ACH50 during this preliminary test.
