Standard HVAC systems require large fans and ductwork to move conditioned air throughout a building, which wastes energy and building space.

BuildingGreen-Approved Chilled Beams

BuildingGreen lists chilled beams that rely on water and smaller ducts to provide HVAC throughout a building.

Within the confines of the BuildingGreen safe space, I wanted to share the Forced Labor in the Building Material Supply Chain Mitigation Framework I shared at the 3/1 First Friday Fika. The intent is for this document to become public, but we are working through some permissions and final editing logistics. The project was collaborative... Read more

Greetings, Green Gurus:

As unbelievable as it sounds, the Environmental PROTECTION Agency has launched a PR blitz in support of their "new use rule" on asbestos. So the BuildingGreen community needs to push back harder. I'm reposting the links to the letter of opposition that Mary Ann Lazarus put up last week. We definitely need more... Read more

Has anyone worked on a WELL project? I have heard that you can expect about 1.5 to twice the effort of LEED coordination but wasn't sure how accurate that was. Any suggestions for determining the possible time commitment of WELL coordination?

Thanks in advance!

Hi gurus,

Do any of you have preferred portable devices for indoor air quality monitoring? I know it's hard to find apples to apples, but ideally temperature, CO2, VOC, PM2.5, PM5 would be on the list. Mid-level accuracy - better than consumer, not as $ as IAQ professional level. Thanks!

Hello everyone! I’m happy to be re-joining the group after a two year hiatus.

Pre-pandemic I got to participate in a few winter summits when I was Sustainability Director at Overland Partners in San Antonio. I’ve recently joined Mahlum Architects in Portland and I’m excited to re-engage in the conversation, this time from the West Coast... Read more

I'm curious who in this group has used ASHRAE Standard 209-2018, Energy Simulation Aided Design for Buildings except Low Rise Residential Buildings?

We've used it internally (minimally) as a reference to help better communicate the goals and activities involved with energy modeling at various phases of design. But it seems like there's... Read more

Hi all, 

Thank you again to those of you who attended the Summer 2024 SDL Summit! We had an unforgettable few days of learning from one another, including from our presenters.

The slides for the 5-minute presentations are below, as well as the BuildingGreen slides from the Summit. Please be aware that we have permission from all... Read more

Has anyone used a commercial heat pump water heater for a large protect?  I have found a few manufacturers for this technology, but want to make sure this is a viable and cost approach to electrical eliminate gas on a path to all electric.

Has anyone documented the Food Alternatives credit as part of WELL or as an innovation credit in LEED?

We all know the climates are shifting, and the ASHRAE standard that gets invoked for energy codes is shifting along with them--though not in perfect sync.  Louisiana is leaping from ASHRAE 90.1-2007 energy code to 2021 IECC (boom!).  The 2021 IECC as published uses relatively old climate maps; for Louisiana, at least, the same as the 90.1-2007...

Has anyone done any museums in which they hired an independent QA/QC specialist? Or perhaps, your firm offers QA/QC services and experise in this area? If so, could you please reach out to me? I'm wondering what firm you used and what your experience was. Was it worth the fee?
