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

If you have been wondering about the Contractor Commitment, we have an update for you!

Several weeks ago, the subgroup leaders and the Steering Committee members gathered to agree on a basic structure for the Commitment. The idea was to align the basic expectations around issues like how many tiers there would be, what would be disclosed... Read more

I am getting started on a research project to evaluate the feasibility, costs, and benefits of using phase change material (PCM) to passively regulate temperature in Minnesota buildings. If anyone has experience designing with PCM, installing PCM, or occupying buildings with PCM, can you share any lessons learned that would be relevant as... Read more

I'm looking to change consultants. Let me know if you have worked with a 179D consultant that you would recommend.

Hello All! 

We are using TallyCat to extract quantities from our REVIT Model, and bring them over to EC3 to get a model GWP (focusing on material categories required to evaluate ILFI Zero Carbon certification).  There are a number of questions that are popping up!!

I am sure there are others trying the same thing, yes... maybe?! ... Read more

As we begin to look into Scope 3 emissions reduction strategies, it's important to understand ways to reduce tranportation emissions to project sites. Is anyone aware of best practices or programs for contractor carpooling to jobsites? I know many of my colleagues travel to work together in one vehicle because of parking limitations, however,...

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.

Chillers are part of larger systems that provide cooling in large commercial buildings.

BuildingGreen-Approved Water Chillers

Because there isn't a single relevant efficiency standard for chillers, approved products use innovations such as magnetic bearings, variable frequency drives, or other technologies that significantly... Read more

Reaching out to the collective knowledge here.  With interest in circular economy and building reuse growing, is anyone leading the charge for the concept of building reuse as a tool for maintaining community identity?  Has anyone seen successful projects with this concept in mind?  I was just in a discussion with a bunch of SDLers, and while...

We look for products with:

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.
