Curious on stories when IAQ testing for LEED or WELL didn't come back with "all clear, everything's good" results we all hope for. 

I have a project right now where we are tracking down suspicious sources and look forward to telling the full story when it's done being written. 

Thought maybe this would be a good safe space to talk... Read more

I have been watching LEED Zero for a while, and have appreciated certain things, but one thing I think is an absolute disaster is their allowance of mainline RECs for claiming Zero Energy and Zero Carbon performance.  I just asked this question on the LEED Zero webinar, and the panelist basically said, "it's part of LEED Zero, therefore it is...

What sorts of boilerplate and legalese will we need on the BIT User site? For example:

I'm not saying you need any or all of those, but I'm just giving a heads-up in case you need to check with your legal advisor.

I can link to those documents from the site footer.

Hi folks,

I’m sorry to be so last minute with this. LEED v5’s second public comment period ends TOMORROW (Monday, Oct 28). As it currently stands, LEED has eliminated its preferential support for FSC over other forest certification programs and is silent on climate-smart forestry.

I’m hoping that the Climate Smart folks in this... Read more

This might be going down a rabbit hole, but in moving to California this year I noticed that "zero net energy" (ZNE) is the standard term, whereas "net zero energy" (NZE) was more common back east. The DOE's 2015 definition (below) uses "zero energy building" (ZEB), which to me implies a building uses no energy at all.

Team SCL,

This was a tough week. My husband coined a phrase "20% laid off."

Unfortunately, 50% of our business is currently impacted by governmental orders stating that our work is non-essential. This is bitter-sweet. I certainly want people to be safe, but we've had to make some tough decisions and in the geographies that were... Read more
