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...

I opened IE11 (Internet Explorer 11) today, and saw a message indicating IE11 will be retired June 15th, 2022. While I have no personal attachment to IE11, it was the only internet browser I could consistantly get to open LEED Online credit templates on the actual website. 

Has anyone found another way to be able to fill out LEED credit... Read more

I was wondering if any design or contractor friend here can kindly share the carbon emission factor of excavation during construction.

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

Does anyone know of a good summary of state and local energy code adoption for new building and ordinances for existing buildings? I know of this energycodes.gov site, but it feels somewhat misleading when you dig into it. For example, in CO, it suggests there is no min code, but there is, and it doesn’t show the extent to which local govs are... Read more

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. 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
