Hi all - I heard from sevearl of you at Greenbuild that you have learned from and perhaps even shared the Path To Zero Carbon series internally at your firms and externally.

Hello everyone,

We are far too often asked to include parking in our buildings (because why shouldn't the average family have 2.1 kids, .8 pets, and 3 cars) and it always grates on me that we are putting so many resources (natural and monetary) into something that is almost certainly single use and will need to be demolished in 30 years...

Friends,

Through AIA work I have been working with Kim Shinn from TLC Engineering. Kim is involved on the ASHRAE 209 development and has been advocating that the AIA, ASHRAE and USGBC align around this standard. Personally I think this is a good idea as I expect that this standard could easily make it's way into regulations and contracts... Read more

Hi all, 

Internally in our organization, we seem to have plenty of horizontal (infrastructure) resiliency expertise, but I'm finding the vertical resources to be lacking. I'm hoping to build a collection of beginner- to intermediate-level resources to help guide practice/design standards for our reference. Any pointers on good info... Read more

Hello- I'm curious if anyone has created a visual or 1 pager "roadmap" on thier SCL committments. The use would be a conversation starter for project site visits (many that aren't SCL projects) to get feedback, suggestions and hear any challenges from Superintendents/PM's. Maybe something that connects to a A1-C4 visual? If you've done... Read more

Hi All,

I try to respect this forum and limit sharing events to the ones that are extra exciting and this is one of them. Coming up on May 20th 4-6pm,  Built Environment Plus (formerly USGBC MA) is launching our Building Tech Forum v2.0 Series.  Here's the link to register: https://builtenvironmentplus.org/building-tech-forum-2020/

The results from the "CogFx" study are compelling, showing that people in environments with low VOCs and low ambient CO2 levels score higher on tests of cognitive function.  Specifically, they show that providing 40cfm of outdoor air per (actual live) occupant results in significantly higher scores than even the "Enhanced Ventilation" scheme...
