Below is a link to a podcast with Bryan Orr from HVAC School.
Bryan interviewed Steve Rogers and Gary Nelson from The Energy Conservatory discussing Blower Door ACH50 measurements vs. Natural Infiltration rates. It is a good talk – Bryan is a great host – and it is also a good opportunity to hear directly from some of The Energy Conservatory researchers – Steve (current President) and Gary (Founder of TEC, inventor of the Minneapolis Blower Door and Minneapolis DuctBlaster).
