Hi all,

The Healthy Building Network, now Habitable, was kind enough to develop printable versions of their Informed Product Guidance for us. I think these are a really great resource for design teams looking to select better product options. While the web version is great, we are using the printable version to hang select sheets around...

Hi all - Can you help me with a list of states with pending electrification/fossil fuel free ordinances? I am providing some technical aasistance for an article that is going to press soon. The author has listed WA, CO, and MA but I'm unsure how far each of these go and if it's technically correct to call them electrification ordinances.

I'm hoping for some help answering the question of whether buildings/communities should pursue net-zero energy on site versus investing in new renewable energy (i.e. through the electric utility) that can be built at a more efficient scale elsewhere in the state. Our utility is asking us this question as we are working through how to get the... Read more

I am putting together a presentation for our local AIA conference specifically about shading devices / dynamic glazing / dynamic shading and wonder whether any of you have experience / feedback from projects that used a dynamic system - exterior operable shading or dynamic glazing (like View, Sage).  Any post-construction / post occupancy...

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.

I took a first pass at content for the Energy Audit best practice, see the uploaded file. 

Huge shout out to Patty Lloyd, Luke Leung, Janet Olsen, and Sarah Gudeman for their webinar on the Power of Peer Networks. They share lots of insights into the value of participating in BG Peer Networks and many others. Ten bucks to Illinois Green gets you access to the recording--I loved it. What would you have said that they didn't?

CEUs are available for reading all the building-envelope product guides and primer. Click here to learn more and take the quiz.

Water and air that penetrate building assemblies can damage materials, cause energy loss, and lead to mold, mildew, or other problems. The products used to address these may contain materials that are... Read more

Question for you all: there is this wonderful graph showing how we can shift mechanical and electrical dollars into envelope investments to make deep energy savings cost-neutral. Have you experienced this on a project?

1-minute or less survey! (two questions, more detail if you want)

Hi Shane and Dennis,

What return address should we use for BIT User forum notification emails?  Ben suggests something like no-reply@bit-user.org but whatever you like is fine.

Once you decide, please let us know who controls the domain name (e.g. bit-user.org or bitbuilding.org).  Ben will send them instructions for editing the... Read more

Greetings Gurus, following the AIA COTE Design for Economy concept, does anyone have a resource for a list of building efficiency ratio "targets" by space type? I've always struggled with this initiative. 

Welcome to the quiz portion of Protect Your Spec: 14 Strategies. 

Learning Objectives
Upon completing this course, participants will be able to:


Identify ways to ensure continuity between the environmentally preferable materials in a project specification, and the less-than-ideal materials that end up used in the final... Read more

I know there are a few of us WELL Performamce Testing Agents / Organizations represented in this group. In the wake of technology talks on this weeks update calls from IWBI, I'm wondering if anyone would be interested in a best practices and equipment small group discussion within the safe space of Green Gurus? Let me know! 

Hi all,

I'm sure many (most? all?) of us have heard the changes to LEEDv4's energy standard are coming. If this is news to you, info on the balloted measures that have passed is available online here: https://www.usgbc.org/articles/leed-v4-energy-update-approved-member-ballot.
