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. Some are even quite funny! The builder we are working with does not have a sign like this, but is open to ideas.... Read more

Has anyone here found an alternative to XPS for the void former?

Hello. Has anyone tackled "tracking emissions from all company-purchased cloud computing" yet? This is in the best category for CC 2.0 and wanted to ask.

We're looking to expand our design performance group - let Peter or me know if you have someone to recommend to us! Here's the description. 

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...

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

Hi, all.

Has anyone used Unicel's Timber Curtain Wall System? It uses engineered glulam wood mullions on the inside with aluminum mullion caps / butt joints. Has anyone gotten close to using it, but couldn't get it procured for a particular reason? They note up to 72% more energy efficienct than a conventional aluminum curtain wall and... Read more
