Air Tightness and Its Impact on Star Ratings
NatHERS will change when improved building air tightness is treated as a valid energy savings strategy along with other envelope measures. A key distinction is that assumptions made in the assessment must be verified in real life by a blower door test. There are major opportunities here, but also risks. Learn more about how the process will work, what a test involves and how much it costs. Importantly, learn how to take reasonable projections and make them a reality. Hear a special perspective on the U.K.’s experience with the same transition – what worked for the industry and what didn’t.
