Hello Folks,
What is your experience with successes and failures in the design process? As a starting point I have listed my Top 5 for success, and my Top 5 for failure. We'd love to see your reactions and look forward to the discussion when we all meet next week at our monthly check-in.

Top 5 reasons for when integrative design... Read more

Hey all - sorry I won't be able to join our call today. I had a client request an emergency meeting today (boo) because corporate mandated that they eliminate fossil fuel use from all their buildings (yay!) by 2025 and they've got a project underway that needs to pivot quickly. 

Had I been able to join, I wanted to share this in case... 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,

Jacob Knowles from BR+A reached out with a request and I’m passing it on to you all.  Jacob’s contact info is at the bottom of this so you can respond to him directly or respond here and I’ll forward it on:

We are working on assembling examples of large wet lab buildings that employ strategies to greatly reduce fossil... Read more

Hi SDL: today is the last day to cast your vote in the voting for Greenbuild by 5PM ET.  

please vote for the terrific program put together on PV23 "The Tools You Need to Design for Climate Emergency Action" with me, Betsy and Beth Heider that will bring together a collection of tools, including brand new ones from Saskia, using the Top... 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

Hello all,

This month's SCDL call was full of great discussion! We decided this month that we are feeling good about where we are for the Task Force Agreement on defining social sustainabiltiy in our work. The aim is to work with this agreement for a while and see if it holds up as a process framework. There was also interest to invite... Read more

We apologize, but the heating fuel cost calculator is no longer on the BuildingGreen website.

Take a look at Efficiency Maine's heating fuel cost calculator instead.

Welcome to the quiz portion of "How to Access the Full Power of Biophilia."

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


In order to successfully contribute to a LEED project, it is important to have an understanding of how the LEED process integrates within a typical design and construction schedule. Every new construction or renovation project, whether large or small, moves through certain project phases beginning with design development, design completion (... Read more

Hi folks,

No details have been sorted out yet, but I wanted everyone to have a heads-up that the SCL Steering Group is proposing that we graduate to a full, stand-alone SCL Summit in 2020. (Until now we’ve been squeezing our Summit into the day before Greenbuild, which is good in some ways, but problematic in others—and limits our time... Read more

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? 

Jenny/Dan:

What types of content do anticipate having in the Documentation Toolkit tab? Here's an example of what we have on LEEDuser:

The layout is a little complicated on LEEDuser, since we had to work with a lot of legacy content, but... Read more

On a large sports project, we worked with the structural engineer to spec low carbon / high SCM concrete mixes. Much of the floor area will be sealed and polished concrete, and a concrete sub is pushing back on the SCMs saying they should not be above 20% (with a preference for 0%) for the polish to finish properly, per the manufacturer. Anyone... Read more

Exterior doors often have poor insulation and seals that allow air through.

BuildingGreen-Approved Exterior Doors

BuildingGreen has different criteria for commercial and residential exterior doors.

Commercial swing (hinged) doors must be NFRC-rated, certified, and labeled for U-factor. They have a maximum air leakage of 0.... Read more

Dear all,

Greetings. I'm presenting virtually to an audience of architecture and engineering faculty in India on the topic 'Introduction to Climate Change and Adaptive Architecture.' What is expected of the presentation is a broad overview of how climate change affects the built environment, challenges faced and some coping mechanisms. I... Read more
