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

Building materials emit massive amounts of carbon long before the lights go on.

In this course, BuildingGreen takes an analytical look at the greenhouse gases that are emitted in the process of constructing our buildings in the first place—the embodied carbon. The report focuses on how architects and designers, working with other key... Read more

Hello SCL,

Hi Gurus!

This query just came from GSA via the Large Firm Roundtable. It seems that one way we can help is simply to route this to the best concrete and asphalt suppliers we know of, so they can respond.  

Can you pass on some information to the large firms sustainability roundtable? GSA, and the White House, just announced new... Read more

Green Gurus –

Clark Brockman brought to our attention an important and impactful opportunity to advance building decarbonization through the US Department of Energy’s proposed rulemaking around water heater efficiency, advancing adoption of heat pumps, while still providing exceptions (and efficiency targets) for electric or natural gas...

Received answers from below questions from NIST Andy Persily

1. Is there a preferred bookends range of CO2 for both “optimal” energy and human performances?

Andy: No

2.Is the ASHRAE ventilation of 1000-1200 ppm average, probably not based on performance, suggesting current ventilation rate is sub-optimal with cognitive... Read more

Facilitating Engagement and Collaboration in Virtual Meetings (or, Avoiding a Goat Rodeo with Many Awkward Silences*)

If you weren't already sitting in virtual meetings every day... We all are now. So how do we facilitate an online meeting in which everyone is focused, engaged, heard, collaborating and problem-solving in an efficient,... 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

Hi folks,

We will be having a call for the Sustainable MEP Leaders group on Monday, April 8 at 3pm Eastern time. Hope you can join us! We'll be talking about our first in-person Summit, as well as diving into discussion about some top-of-mind topics related to being a sustainability point person within an MEP commercial practice. Here’s...

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 have experience pursing SITES certification on an essentially a zero-lot line project?

We are required to achieve silver certification, but the project scope/phasing recently changed and the entire site/parking area was eliminated and we no longer have a green roof. It still appears we can meet silver certification as so few... Read more

In our quest to create a low carbon future the lectrification/Decarbonization working group is planning spend the next 10 months creating tools to advocate for electrification:

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.

Welcome to the quiz portion of Passive House on Campus: Eight Exemplary Projects​!

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


Explain the primary reasons that higher-education projects are pursuing Passive House certification, including its impact on the environment and occupant health... Read more

Colleagues,

As we all know, ventilation rates must be kept the same between the LEED Baseline and proposed energy models. However, we're aware of projects that have been able to claim energy savings associated to reducing ventilation using systems like Aircuity. 

Have any of you successfully claimed credit for reduced airflow due... Read more
