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...

There are so many great contractor-related sessions at Greenbuild this year! I doubt I'm alone in trying to choose between sessions.  

Is there interest in debriefing with SCLers the week after (say Novemeber 9th at 2pm ET?). We could share the golden nuggets from the sessions we attended, saving everyone from wading through the session... Read more

Has anyone had any success with achieving the LEED Building Envelope commissioning points with an alternative compliance path using the requirements of the PHIUS verifier? It seems like an unnecessary duplication to ask the client to pay for a BECx agent and a Passive House verifier. Or am I missing something? I can't find any LEED... Read more
