Interior doors may be a source of indoor emissions, and wood can be unsustainably sourced.

BuildingGreen-Approved Doors

BuildingGreen approves interior doors made from FSC-certified wood or reclaimed wood as well as composite doors with environmental features like:

Seeing Jen's post prompted me to write in support of the Madison Park Technical Vocational High School program (Greenbuild Legacy Project). I spoke to the students earlier in the year and it is a great program. I'll reach out to our HR about interns.

I have been watching LEED Zero for a while, and have appreciated certain things, but one thing I think is an absolute disaster is their allowance of mainline RECs for claiming Zero Energy and Zero Carbon performance.  I just asked this question on the LEED Zero webinar, and the panelist basically said, "it's part of LEED Zero, therefore it is...

Hi all! I'm very excited to report that we have interest from a developer client in tracking embodied carbon through construction. We have issued construction documents and the construction managment team is begining the process to establish the GMP.

We're looking to use EC3, and/ or ZGF's LCA analysis tool for concrete to look at how we... Read more

Happy Friday, SDL!

We're running a Tally WBLCA for an environmental education center, which has a very small floor area but a fairly robust concrete/steel structure. Still, I was surprised to find an intensity of over 1,000 kgCO2/m2 for the building.

This is way higher than the general benchmarks I've found in the CLF's database,... Read more

I'm looking to compare using an electric tower crane vs a diesel generated tower crane.  I've got the average gallons/hour for the size of crane I'm looking at, but when I reached out to the crane manufacturers, they can only tell me what size electric supply I need to provide, not the kWh usage for the cranes.  I know that it varies depending...

Does anyone here have a draft spec for low embodied carbon concrete they could share? I see the GSA has a standards sheet with MGWP limits, but we are hoping to actually specify the mix for upcoming projects.

My apologies if I posted this question twice ont he forum - I am a newbie on this forum.

Anyone knows how to import an structural emobdied carbon project file into architectural project file of the same proejct to generate a combined Sankey graph?  My Building Transparency/CLF contacts haven't got back to me for a week now...

Metal roofs can also provide high solar reflectance, minimizing a building’s contribution to the urban heat island effect. 

BuildingGreen-approved

Materials and finishes recognized by Energy Star maintain solar reflectance levels after three years of use of 50% for low-slope and 15% for steep-slope. Some unpainted metals and many... Read more

Anyone using the USG EcoSmart drywall? I'm writing a short product review and am looking for some quick feedback. I'm particularly curious about reduced greenhouse gas emissions and overall cost. Thanks! Brent

I was recently asked if there is a way to quantify financially what one MT eCO2 might be worth in the context of a building owner reducing their own carbon emissions.  How do you put a dollar value on those reductions?  Does anyone have experience with that or can you point me to the correct resource to answer this question?
