I'm hoping someone knows the anser to this question. For the LEED ND certification the minimum requirement is "The LEED project should contain at least two habitable buildings and be no larger than 1500 acres." Does habitable mean buildings with dwelling units?

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...

Hi Green Gurus (esp. Sustainable MEP leaders...)

I'm looking for suggestions of contacts for MEP consultants, especially in the Chicagoland region, ideally with sustainability highly integrated into the work, specialization in geothermal systems, and indoor agriculture. (doesn't necessarily have to be all-in-one)

For context, we... Read more

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

Good daylighting intentions can end up increasing glare and solar heat gain.

BuidlingGreen-Approved Lightshelves

We look for lightshelves designed to reflect direct sunlight onto the ceiling, turning what could potentially be glare into diffuse, ambient daylight that penetrates deep into the interior of a building.

Hi all,

Here's a good follow up to Maria's steel question on Monday.  We have a Midwest project that unfortunately (from a carbon perspective) is required to use a traditional, thick precast facade.  We’re working with the contractor and potential future (not yet bid out) fabricators to determine an appropriate % of pozzolanic material...

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

Curious what people's 'best' experiences or recommendations are for load calculations and energy modeling regarding electrochromic glazing... hoping I can lean on others as it's just now becoming more of a talking point in our market here in Omaha. 

Specific questions including whether load and energy modeling software are separate (... Read more

Hi all,

We have an institutional client who has tired of LEED and is instead putting forth EarthCraft Light Commerical as a replacement certification (they like the performance verification & lower cost that ECLC provides).  Has anyone used ECLC? It seemed an odd choice but wanted to hear from others on their experiences. The... Read more

I'm working on the Best Practice pages, and I want to verify the role of "BITuser experts" (analogous to LEEDuser experts, as shown on this credit page). My questions:

I'd love to hear thoughts from the design, consulting, and contracting firms in this group about ways to make our specs more inclusive, or at least less exclusive to minority and women owned contractors and subcontractors and others that have not had the benefit of what a recent "Equity in Specs" presenter termed the "Fathers / Brothers / In-...
