Hi Everyone!

Does anyone have a good resource for whole-building embodied carbon benchmarks broken down by building use and building category (structure, foundation, envelope, interior)?

I know of CLF’s 2017 Benchmark Study (great resource!) and the One-Click LCA study on European Buildings but are there any others?  I know many... Read more

Hi folks,

USGBC has commissioned this survey of the building industry about Federal tax incentives for building efficiency. They will be sharing results with congressional staff, so this might be a good opportunity to give them feedback from the field!

And it's just 10 minutes.

And, after you do the survey if you want to... Read more

Hey, all. Confirming the forum index on the front side of the pay wall will be searchable. Thanks.

Hi,

I believe a while back there was communication about a hard hat recycling program. Does anyone have any information about a hard hat recycling program? The contractors in the midwest have finally switched to the new style of hard hats with the chin strap and are requiring all subcontactors to comply by July 1, 2024. I'd like to... Read more

Hi All,

I just became aware of the attached detail (if I uploaded it correctly) for a project in Portland, OR going out for permit at the end of this week.  Has anyone located the radiant tubing at the bottom of concrete like this before?  It doesn't sit right with me, though I cannot pinpoint exactly why.  Our consultants and the...

Hi Green Gurus,

A "fun" take-away from the sustainable MEP Leaders Summit (just ended today):

Inspired by Passive House, we are embarking on a campaign: "Low Load Buildings Are SEXY".

One idea we have is:  what if the AIA design awards set limits on metrics like heating loads to meet basic eligibility?

Hello everyone,

We are far too often asked to include parking in our buildings (because why shouldn't the average family have 2.1 kids, .8 pets, and 3 cars) and it always grates on me that we are putting so many resources (natural and monetary) into something that is almost certainly single use and will need to be demolished in 30 years...

In the Passive House session at the Winter Summit, I spoke about a Massachusetts DOER report that found that meeting the new energy code in MA (passive house or better in most cases) is cheaper for some building types than traditional construction. Some of you asked to see the report. It was a power point show. On page 34 of this slide deck... Read more
