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

Hello,

We’re looking for Design Energy Code Equivalents for Chinese commercial energy codes. Do any of you have  any good sources? I’ve only found data comparing ASHRAE 90.1 2013 to the Chinese Code at that time. We understand the Chinese code require a 65-75% energy savings over the baseline but don’t have good information for defining... Read more

Friends,

As some of you know, I joined Perkins Eastman last year and it has been amazing. After years of being the Sustainable Design Leader at my last firm, this move has meant I can concentrate on project work because we have such an AMAZING team, led by Heather Jaurequi and Tanya Eagle. Unfortunately, that also means I'm not in the... Read more

On a large sports project, we worked with the structural engineer to spec low carbon / high SCM concrete mixes. Much of the floor area will be sealed and polished concrete, and a concrete sub is pushing back on the SCMs saying they should not be above 20% (with a preference for 0%) for the polish to finish properly, per the manufacturer. Anyone... Read more

I'm sure most (if not everyone) is aware that LEEDv5 is under public review until May 20, 2024. I know I need to make time to flip through it, review, and comment, but I'm having a heckuva time protecting the time in my calendar to do that. Anyone interested in joining me for a 60 - 90 minute meeting to do this together as an accountability... Read more

Has anyone had experience working with Hyper Metro (http://hypermetro.co/)? If so, did you find this company to provide value especially in dense urban environments where on-site segregation poses challenges to manage multiple C&D material streams on site?

We've updated the Salesforce BIT Community domain from "https://southfacecommunities.force.com/BITBuilding/s/" to "https://www.bitbuilding.org/s/" and there are a few links on BITuser that point back to the community that need updating.

Asking for a colleague:

"Have you ever had a large number of fire retardant tarps used to temporarily enclose a building during construction? Do you know of any solutions for recycling/reusing them or another product that doesn't use toxic fire-retardants that meets the performance criteria?"

I think we've all seen poly or fabric... Read more

Hi folks,

I hope you've seen the plug to sign onto the letter that's generated a flurry of messages on Green Gurus--I also emailed it out directly to everyone. We've got lots of architects on board, and a handful of engineers, but I think we just have one contractor so far (Thanks Theresa!)--it would be really awesome to have more.

Conventional asphalt and concrete contribute to excessive stormwater runoff and pollution.
