Friends,

We put a lot of effort into air tightness design, detailing, and construction administration, often including 6-sided mockup and parital or whole-building blower-door testing.  For commercial buildings, these tests measure air leakage in cfm/sf at 1.57 psf (75pa).  

I came across this research paper several years ago, but... Read more

There has been some great press in the last couple of days related to Healthy Building Network's (HBN) newly released report "Chlorine & Building Materials Project".  That report is over 200 pages long, but there is some great commentary available that makes the top issues much quicker to grasp.

Chlorine is used to make PVC and PVC... Read more
