Greetings Heat Pump Water Heater (HPWH) advocates!

We have an opportunity to advocate to the US DOE on behalf of HPWHs!

Geoff Wickes is an emerging technology product manager for NEEA (Northwest Energy Efficiency Alliance) currently focused entirely on HPWH technology, policy, and market adoption (and in full disclosure: also a... Read more

We are pursuing sustainability goals (and documentation of those goals) outside of any certification/rating system for a current project.  However, we have set up a criteria list of goals by following strategies/credits from many of those systems (LEED v4 EPDs, SITES v2 threatened tree species, WELL v2 mindful eating, etc.).  This approach is...

Have any of you heard of anyone ever using phase change material (PCM) "movable partitions" as a resiliency strategy to mitigate indoor overheating during a heat wave in passive buildings? You'd keep them stored in a basement or cool room, and deploy them into habitable spaces during the heat wave to keep the space cooler than the exterior... Read more

Kristen Fritsch, in the thread about ipe wood, asked about resources comparing the carbon footprint of transporting building materials vs the transport mode.  There are people who spend their lives on this topic that I won't presume to speak for, but I'll share a few observations:

Even though freight transport is something like 7% of... Read more

Welcome to the quiz portion of "How to Access the Full Power of Biophilia."

Friends,

We put a lot of effort into air tightness design, detailing, and construction administration, often including 6-sided mockup and parital or whole-building blower-door testing.  For commercial buildings, these tests measure air leakage in cfm/sf at 1.57 psf (75pa).  

I came across this research paper several years ago, but... Read more

Hi Folks - sorry for the late notice, but I just heard about this two days ago and needed to get confirmation that I could share the request with htis group.

The opportunity is for business leaders in energy, efficiency, construction and design (i.e. all of us!) -

As you know, the flow of the historic federal infrastructure and... Read more

Does anyone have a good recommendation for getting started with energy modeling with future weather files? We use a combination of Sefaira and Climate Studio, but open to suggestions. Even just links on how to approach this for making good recommendations to clients. Thanks in advance.

Our all-volunteer Advisory Board helps BuildingGreen identify the most critical topics for our coverage, and directs our research as we investigate these topics and bring them to our readers. Their distinguished and varied service in the field of environmentally responsible building is an inspiration.

Hello SCL, 

If you didn't attend last week's SCL Summit, then I'll sum up one of the major takeaways: SCL members NEED TO COMMENT ON LEEDV5. The stakes are high, particularly around waste. 

Luckily, Amanda Kaminsky is making it easy for us. She has drafted a sample comment based on our discussion at the Summit. 

If you have... Read more

HGA is collaborating with the University of Minnesota Climate Adaptation Partnership (MCAP) to research how the AE industry is currently using climate projection data, and what they need in order to grow their use of data. MCAP is currently producing a set of dynamical downscaled climate projections for the state of Minnesota and unlike other... Read more

Everyone agreed during last Friday's meeting that we want to call the site BITuser. The question, however, is what domain name should be used.

Whatever domain name is chosen, it will redirect to the actual site URL -- https://bituser.buildinggreen.com (similar to how LEEDuser.com redirects to https://leeduser.buildinggreen.com).

Returning to work: for many, it’s unthinkable without some kind of reassurance that leadership and the facilities team have taken all possible precautions. Lots of organizations are weighing in on what we should pay attention to, but how do we know if it’s working?

The free Re-entry program from Arc is a tracking and measurement... Read more

Dear all,

For a specific existing building application, we are looking for a half inch insulating glazing unit, preferably with low-e coating. Based on my research, 5/8" seems to be doable (1/8" glass + 3/8" air gap + 1/8" glass) but I'm yet to find a viable 1/2" solution. Have you come across any on your projects? Thanks for your...

Green Gurus -

I’m honored to be co-chairing, along with Caryn Brause FAIA, the ACSA/AIA Intersections Research conference at UMass Amherst October 2023.   The theme, "Material Economies," was developed with an eye for inclusivity for academics and practitioners alike, addressing critical emerging issues around architectural material...

My firm didn't have representation at the winter summit, but I've just read the report (thank you, RoseAnn!), and was really glad to see there was conversation around mass timber. I'd love to talk with anyone who was involved in that roundtable to get a deeper download about the discussion. We've been doing a lot of mass timber buildings and... Read more
