Mark Jansen, of Energy Efficient Homes Midwest EEHM, who rated our Bloomington, IN LEED Platinum home about two years ago, originally gave us a 200cfm / 50 Pa for air infiltration. Mark was convinced that the measurement was even tighter, but he didn't have a smaller reducer ring for the blower door. He showed up today, with blower door and more rings! Guess what? Our house tested at ~155 cfm / 50 Pa! A nice bit of news validating the conscientious construction of our SIPs panels house! The meter shows 155 cfm / 49.6 Pa. Close enough to 155...that's really TIGHT!
Big thanks to Marko Spiegel of Conservation Technologies International, CTI, for his detailed design, guidance, and creativity. His mastery of advanced energy conservation techniques used in our design allowed us to get to a pretty spectacular level!
