Following up something I mentioned at the summit - the EPA is hosting public comment webinars related to the IRA and construction. The first one seems particularly relevant, 3/2/23 from 2-3.30pm EST “Reducing Embodied GHG Emissions: Construction Materials Prioritization and Environmental Data Improvement”. Good opportunity to have our voices... Read more

Does anyone subscribe to Green Badger? Do you find it valuable?

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.

My question to MEP friends in the Green Commons: In... Read more

Hi All,

I'm working on a LEED for Schools project under 2009, and received some amorphous comments back about our Mold Prevention Plan. We used the LEEDuser template as a guide, while also referencing the EPA document the credit is based around, but the reviewers feel we haven't provided proper metrics. The EPA plan is something like... Read more

Colleagues,

As we all know, ventilation rates must be kept the same between the LEED Baseline and proposed energy models. However, we're aware of projects that have been able to claim energy savings associated to reducing ventilation using systems like Aircuity. 

Have any of you successfully claimed credit for reduced airflow due... Read more

Hi,

We have a market-rate housing highrise project that is going through VE right now: we need cheaper/lighter rainscreen claddings than precast concrete or GFRC.

If you've gone through this similar exercise, I would greatly appreciate recommendations for cladding manufacturers/products with EPDs available. We are open to metal... Read more

ASHRAE 209 in all its glory has been uploaded. This will impact our architectural process, for better or worse, so we should embrace it and learn from it. The revised AIA Energy Modeling Design Guide (due out next year) has been timed to correspond roughly to 209 coming out and will include references to it. The first few energy modeling '...

Hi all, 

I'm looking for critical mass here. Do any of you have or know of clients who are requiring Just labeling for their consultants? I've heard that Google is asking this, and wondering who else might be on that course. Thanks! 

Hello Gurus,

I’m writing to share with you an effort a small group of lighting designers from the Boston area started which is now rolling into a large scale effort.  We’ve put together a Lighting Advocacy Letter to accelerate the sustainability of lighting products. Inspired by the AIA Materials Pledge, the letter is intended to... Read more

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.

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

Curious if folks know of any resources on hempcrete, specific to durability.  We have a one-story carbon-neutral operational energy project where the design team and client have bought into the aesthetics and carbon-sequestering potential of hempcrete, and amazingly it is looking to be no more expensive than a more typical concrete wall...

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,...
