Conventional stormwater management treats rain as the enemy—a dangerous and destructive force that must be deflected away from building sites as quickly as possible.

But as we pave more and more of paradise,... Read more

Does anyone subscribe to Green Badger? Do you find it valuable?

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

Greetings!

Back again re: the work we're doing with City of Cambridge, in their great leadership efforts to develop EC policy/regs/incentives and reporting requirements.

Thanks to those who responded earlier about the effort it takes you to conduct WBLCA - now we're diving into it in more depth and wanting to get together a focus... Read more

Wood was the first material used in window frame and sash construction, and it remains popular for homes with its warm feel and relatively high energy efficiency.

BuildingGreen-Approved Windows

Wood windows must achieve an NFRC-certified unit U-factor of 0.22 or lower. Manufacturers also must demonstrate that their highest-... Read more

ASHRAE 209 in all its glory has been uploaded. This will impact our architectural process, for better or worse, so we should embrace it and learn from it. The revised AIA Energy Modeling Design Guide (due out next year) has been timed to correspond roughly to 209 coming out and will include references to it. The first few energy modeling '...

Team,

After talking to UL today, I thought it will be good for them to do a presentation on what they see in embodied energy/carbon road map of MEP equipment can be like.

Should we schedule them for a 30 minutes presentation in the next call?

Best,

Several weeks ago, the subgroup leaders and the Steering Committee members gathered to agree on a basic structure for the Commitment. The idea was to align the basic expectations around issues like how many tiers there would be, what would be disclosed... Read more

Hello SDL friends,

It has been an amazing opportunity to collaborate with so many of you through this group or through my work with Tally, the USGBC, ILFI, and in my role as an environmental researcher at KieranTimberlake. This is not so much a goodbye as it is a "hope to see you soon." I am making a shift away from building design into... Read more

Hi SDL: Please see attached letter to USGBC about the urgent need to address climate change in the next iteration of LEED v4. It's based on the realization that in the last few years it has become clear that climate change has become the dominant global threat to humans and our fellow species. And it has also become clear that the steep... 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

As we begin to look into Scope 3 emissions reduction strategies, it's important to understand ways to reduce tranportation emissions to project sites. Is anyone aware of best practices or programs for contractor carpooling to jobsites? I know many of my colleagues travel to work together in one vehicle because of parking limitations, however,...

Does anyone have an opinion of Autocase?    https://autocase.com/

I had not heard of this platform before.  Their website says that some firms in the group are customers / users.   Website does not do a great job of describing exactly what they do.  Is there value?

Thanks,

Allen
