I would be interested to hear which parties in our group have participated in the CDP Program and how you are reporting your efforts.  I have talked to several contractors that just submit the data for their offices. I always feel like it is asking about our operations including the jobsites, and wonder how you get there.  I am very much... Read more

Hello, 

I am struggling with understanding if I should be using Annual Marginal Emission Factors (MEF) or Annual Average Emission Factors (AEF) for evaluating different building design decisions.

Everything I know is from this document. So as I understand it ... an individual building or retrofit is going to change the marginal... Read more

Hi all,

I've tried a couple of different search terms for the forum but haven't been able to find any past conversations on electrochromic glazing yet (which makes me suspect I might be missing something...). We have a potential opportunity to use it in a vertical curtain wall application with a client that is very interested in the... Read more

All,

Our firm has been struggling to find carbon reduction strategies for concrete that move us beyond a fly ash only approach. Frankly, the knowledge just isn't there internally or with our consultants. We've known that there are a few folks out there that have a deep bag of tricks, but we haven't had the chance to work with them... Read more

A couple questions for this group. I know we're having a Green Commons meeting on this next week. But can anyone comment on the following questions?

-Have you or your firm split the benefit of the 179D with a client? Is this typical?

-Is prevailing wage a requirement for all 179D benefit, or does it follow the same lines as... Read more

Would anyone have an example LEED Homes v4 specification they would be willing to share?  We are working on our first LEED Homes project, a midrise low income housing development here in Houston.  We have a LEED Homes provider, but she will not provide the specifications, which seem to be quite different in requirements and submittals from our...

Show & Tell Break-out Session: Post Occupancy Evaluations and Occupant Behavior

Presentations: 

I'm wondering if people are seeing any increase in WELL or Fitwel certification interest? Or any other 3rd party systems aimed at health and wellness? WELL seems like a higher bar and now WELL v2 offers more flexibility. Is interest and adoption of 3rd party health and wellness certs growing?
