Hi all!

I'm working on my first energy positive / passive house multifamily building and trying to figure out the trash/recycling chute. I am curious what solutions you have employed to make the trash chute air tight? We have excluded the whole chute from the envelope. Do you use airtight doors (and which ones?) at each floor trash/... Read more

Is anyone aware of research or guidance that has looked at VOC’s from roofing products and ventilation intakes? I’ve done some searching, and focus is mainly on managing the construction process to reduce installer exposure. 

Thanks for any help!

Huge shout out to Patty Lloyd, Luke Leung, Janet Olsen, and Sarah Gudeman for their webinar on the Power of Peer Networks. They share lots of insights into the value of participating in BG Peer Networks and many others. Ten bucks to Illinois Green gets you access to the recording--I loved it. What would you have said that they didn't?

Does adding solar panels reduce a building's EUI?

Existing operational use of a building is 80 kBtu/sf/year. When we add solar, it will change the source of energy but does not change the usage.

My understanding is that the EUI does not change, but it would be good to hear from others.

It's energy consumption at the point... Read more

At our SAL call today, folks were talking about how there was just too much to read about DEI. This is the best short summary I have read about the problems of incorporating it into the organizations where we work. It's much easier to talk the talk than to walk the walk because it takes time and accountability.

Hi all,

Here's a good follow up to Maria's steel question on Monday.  We have a Midwest project that unfortunately (from a carbon perspective) is required to use a traditional, thick precast facade.  We’re working with the contractor and potential future (not yet bid out) fabricators to determine an appropriate % of pozzolanic material...

You’ve probably heard that wood products are carbon neutral. You might also have heard that timber harvesting causes immense carbon emissions.

Which is it?

Could it be both?

Hi,

I imagine you've already considered this, but I wanted to mention it before you cross the point of no return...

The name "BIT Building" has the potential to be misunderstood out of context because it sounds like it has something to do with Bitcoin.  I don't think this is a huge problem, but you may want to evaluate the risk... Read more

Hello SDL Leaders,

Over the past month, I have been working with ILFI to navigate the question of residuals in LBC compliant products vs. products reporting for a Declare label.

Through our conversations, it came to light that ILFI considers the LBC Red List threshold to be 10,000 ppm, rather than the 100 ppm written into the... Read more

Hi All, wanted to share this webinar below :
The AIA 2030 Commitment and the Design Data Exchange (DDx) have transformed the way architecture firms collect project data on energy and carbon metrics, but it has never been a good place to visually understand these metrics. Architects tend to be visual people and have an intuitive... Read more
