Last week our passive house colleague John Semmelhack of Think Little, who has been assisting us with our mechanical design and is performing the quality control testing, performed the pre-insulation blower door test. Thanks to both meticulous planning and excellent execution with an outstanding result of 0.34 ACH50 / 0.023 ELA50!
(For reference, the Passive House Certification threshold is 0.6 ACH50 or 0.05 ELA50).
