Hi all,

We are about to start a affordable housing passive house project in Boston and in a few presentations I've seen great signs that builders use to try to get the point across to subs as to how important air sealing is.

Hello, what acceptable levels of air quality are you using to evaluate natural ventilation strategies for your projects?  In our Living Building we only open windows when PM10, PM2.5, etc. are within LBC and WELL limits.  In a seasonally smoggy urban environment, this limits how often we can utilize natural ventilation even if the outside...

Hi SCL, 

Just thought I would share an interesting piece from Construction Dive about a lack of guidance on when to halt work due to bad air quality--from wildfires or otherwise. A few SCL companies are mentioned here as having their own policies, but I was pretty shocked to learn that this isn't required by OSHA.
