Hi all, has anyone come across a comprehensive (and recent) study looking at how long buildings actually last (beyond Stewart Brand)? I know of plenty that look at the benefits of reuse, but none that look at existing building stock and how much has been reused vs. demolished. 

As we start looking at embodied carbon metrics, I can't help... Read more

Hi folks,

I'm looking into lower-carbon pipe options for HVAC and plumbing. The MEP 2040 has slides from a Buro Happold study in 2020 showing PEX to be much lower in embodied carbon than copper, which is unsurprising. CPVC is also a lower-carbon option.

But PVC has its issues and neither PVC nor PEX are recyclable (especially if... Read more

Hi SD Leaders,

As you may be aware, this past April a group of manufacturers calling themselves the Living Product 50 responded to the letters that many of us sent about five years ago advocating for transparency in their product ingredients.  A copy of that letter can be reviewed about midway through the page at this link:  https://...

Seeking a dashboard system that will take energy use data from individual (college student) apartments to display in the lobby. Something where the display is both educational, easy to understand, and that could inspire a little friendly competition. Welcome any recommendations you have installed on projects or have seen that would be cool to... Read more

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

We have an MEP engineer that is calculating peak loads at about 6 times passive house levels on a large commercial building that is at or near passive house levels of insulation and air infiltration. We suspect one reason is that he is figuring a 50% efficiency level for the ERV. We are showing him ERV systems with 80-90% efficiency, but they... Read more

hi all! I'm almost at the finish line with this year's 2030 reporting...whew. I'm running into an issue that I wanted to throw out to this group, regarding the zero tool and national average baselines. Hoping some of y'all who manage your firm's 2030 data, or are just more familiar with CBECS and related data, have some insight / experience to... Read more

Following the summer SDL summit - we formed a spinoff user group called "Carbon Sync" to discuss Life Cycle and Carbon Assessment tools like Tally and Athena.  We've had three successful calls with folks sharing a couple 5-minute presentations about various studies and explorations.  We have a mix of experience levels - but are collaborating...

Hello Everyone,

Here is the 2019 SCL Demographics Report, thank you to everyone who submitted responses. Enjoy!

The SCL Salary Survey Report will be coming next and please note that the Salary Survey is only distributed to those who participated.

All the best,

All,

The current version of the program manual includes ID numbers for the best practices, as shown below. I know we want to keep a quick reference number or ID, but though it would be worth asking if we want to use the below, reorder them in some way, or use a different kind of ID. Opinions?

Thanks,
Jenny

Hey Peer Network! Curious, if we can crowd-source a solution here for the pervious pavers at our Omaha office (climate zone 5A). Apparently over the years we've tried to add different kinds of fill here (gravel) but it keeps... disappearing. Any recommendations with either a replacement product or fill item? 

Glazing connects occupants to the outdoors, but with so many opportunities for air leakage, poor insulation, and thermal bridging, glazing is the primary weak link in building energy performance.

BuildingGreen approves glazing that offers strong energy performance properties for a variety of... Read more

Hi everyone,

I’d like to invite you to join this Friday’s webinar hosted by the Embodied Carbon Network: Using Whole Building LCA to Reduce Embodied Carbon within LEED and Beyond, and to follow up with a tool that I presented at this summer’s Architecture SDL summit, which ZGF has now upgraded and made free to the industry at large....

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
