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

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,...

Anyone know what stages does CARE include? Does it include B1-5, C1-4 or D?

Thank you!

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...

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...

I just saw this post from Conor on LinkedIn.

Starting in January 2019, all new Columbia Construction Company projects require LED temp lighting.

Are others doing this too? Frankly, given all the benefits and how quickly the industry is matured, it's hard for me to understand why anyone would use anything other than LEDs on a job.... Read more

Apologize in advance if this has been posted before but we are trying to get manufacturers of stage curtains to give documentation that proves that the product does not have halogenated fire retardants. Manufacturers say they don't have them or concentrations are limited to 100ppm but they don't seem to have documentation to provide for it.... Read more

Hi Gurus!

I'm desperately seeking any case studies (past/currently on the boards) of labs that have been designed without natural gas infrastructure (the topic I have to debate is about commercial spec labs but any lab case study, wet or dry, is welcomed). This is for a development authority that will be setting guidelines for new... 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

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! 

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

With the increasing need to support design with techncial expertise, I am curious to hear how others are meeting this challenge.  Do you build energy models in-house?  Do you have a team of experts whose sole responsibility is to support design teams with tasks such as energy modeling and LCA, or is that expertise distributed throughout the...
