Hey everyone, HNY!

I'm looking for help in vetting the sustainability cred of uPVC polymer window systems, specifically as an altnerative to traditional PVC vinyl frames. We recenly had a presentation from Intus Windows, who claim that their uPVC frame systems have a low-toxicity profile and excels in performance for thermal efficiency,...

Hi there colleagues!

Out of curiosity, do you plan on attending Greenbuild in person in San Diego in September? My staff asked me if we were going and my answer is partially contingent on the extent to which attending would mean getting to see some of our favorite people (read: all of you). Looking forward to taking the temperature of... Read more

Welcome to the quiz portion of Improving Resilience!

IMPORTANT: This quiz covers five related articles within this topic. 

Learning Objectives
Upon completing this course, participants will be able to:


Prefabricated, or modular, buildings can provide environmental advantages over conventionally constructed buildings. They are built in factories where manufacturing and cost can be tightly controlled, so materials are kept out of the elements, there is less waste, and thermal properties and air sealing can be enhanced. There are also fewer... Read more

Hardware has to be durable and resist weathering to ensure that features such as doors function properly.

BuildingGreen-Approved Hardware

BuildingGreen approves hardware that uses post-consumer recycled metal content beyond what is standard in the industry. Products from manufacturers that have engaged in information transparency... Read more

If only a few of the Best Practices will have checklists, which will be included under the "Implementation Toolkit" tab, I'm thinking we can simplify them (compared with LEEDuser).

I've attached a screenshot of a LEEDuser checklist. But I don't think BITuser will need the four types of icons, and the legend will take up more space than... Read more

Hi everyone!
I've seen a lot of claims over the years of living walls or planted buffers that can mitigate *outdoor* air pollution and have always assumed there's no real scientific basis for that idea, unless we're talking an actual forest that's 10s of feet thick. Am I wrong? Are there examples of living walls that actually have been... Read more

With depth of thought and a broad view of the horizon, Candace Pearson can take a nuanced vision and sharpen it into focus, propelling the team around her forward. Operating in all three of BuildingGreen’s service offerings—publications, consulting, and peer networks—she finds pragmatic ways to fundamentally shift how we create our built... Read more

Dear SDL: Thanks to all who have already given their support to the AIA Resolution on Urgent and Sustained Climate Action. We're into the final push of getting out the vote to pass the resolution next Wednesday, June 5th afternoon in Las Vegas. This requires 2/3s of the voting delegates to pass. So we're asking anyone who 1) is attending as a... Read more

Happy Thursday, all!

I will be presenting with my colleague, Emily Hoffman, and our counterpart from Seattle, Duane Jonlin, on how firms can contribute more to aggressive energy and carbon targets, from the perspective of three people that see thousands of projects each year.  We see the best and the worst, and we're convinced that our...

Hi all,

We have a newly constructed, core/shell project having some hot water issues in the core restrooms.

There is a 0.35 Toto lav installed throughout. The hot water heaters are adjacent on each floor, located in the janitor closets. We did the math, and there could be a gallon of water standing and cooling in the pipe between... Read more

Good morning, All,

Just a bit of news this morning.  My family and I are moving back out west!  I am continuing in my current role with EwingCole, but will be doing so from Portland, Oregon.  Although North Carolina has a been a wonderful place for us for the past 13 years, it is time to be close to family in the northwest and southwest...

Hi there SD Leaders,

We're running an LCA on one of our projects that's about to start construction that has had serious embodied carbon goals and I got a result that really surprised me. I haven't been able to find any obvious/glaring issues with the work, but these results are strange enough that I'm not feeling confident. I'm hoping... Read more

If anyone else has gotten confused going between parts-per-million and percentages (parts per hundred!) for material reporting here's a little infographic that might help. Feel free to use or improve!
