My firm didn't have representation at the winter summit, but I've just read the report (thank you, RoseAnn!), and was really glad to see there was conversation around mass timber. I'd love to talk with anyone who was involved in that roundtable to get a deeper download about the discussion. We've been doing a lot of mass timber buildings and... Read more

Hi folks,

We often hear from you with a suggestion of someone who would be great for the network, and a question about how to refer them. We've now made that easy, with three steps laid out in an Outreach Toolkit that's posted in the left margin of the Member Directory.

So, if you're thinking of someone to invite or come across... Read more

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

Hello SCL, 

If you didn't attend last week's SCL Summit, then I'll sum up one of the major takeaways: SCL members NEED TO COMMENT ON LEEDV5. The stakes are high, particularly around waste. 

Luckily, Amanda Kaminsky is making it easy for us. She has drafted a sample comment based on our discussion at the Summit. 

If you have... Read more

Team,

As you all probably saw, Boston is discussing using both CEI (carbon emission intensity) and EUI as basic scope of work.  Maybe the more surprising thing is China announced a new building code next year to include carbon emission analysis as a basic scope of work for all buildings.   New buildings in 2022, among other things,...

Air movement keeps occupants comfortable when it's warm, so cooling setpoints can be higher, and natural ventilation is a viable option even at higher temps and humidity.

Andrea first became familiar with BuildingGreen in 2010 when she and her husband moved to Vermont and built their own passive house from the ground up. BuildingGreen’s president Nadav Malin heard about the project and asked if the staff could take a tour, and the rest is history. She joined the BuildingGreen team part-time in 2011 to work on...

We are working on a multi-family project in Hartford that is townhouse style so each unit has an exterior door. The client has requested electronic key fob hardware. Has anyone had experience with retrofitting a passive house door with electronic hardware or have they used a door that is already fitted with electronic hardware?

In the Passive House session at the Winter Summit, I spoke about a Massachusetts DOER report that found that meeting the new energy code in MA (passive house or better in most cases) is cheaper for some building types than traditional construction. Some of you asked to see the report. It was a power point show. On page 34 of this slide deck... Read more
