Hardly anyone was using it, though—not only because they didn’t have to, but also because there just wasn’t a pathway to achieve many of the new credits in the rating systems. Especially the product-related credits in the Materials & Resources category, along with the Low-... Read more

I am wanting to take the pulse of this group on behalf of a manufacturer who has asked us a similar question.

The company in question makes wood products and has had FSC CoC for over a decade. Recently, they are encountering issues with sourcing FSC for about 50% of the wood species they offer. There just aren't FSC sources available.... Read more

Hi all,

All members of the WA Building Code Council received an email from Tim Attebery of the Washington State AGC and I'm trying to make sense of the role of the AGC and whether it is representing the consensus option of general contractors in Washington or not. The letter is very much against the energy code advancement, which... Read more

This is sort of dragging up an ancient topic, but curious how your firms are currently addressing accreditation (LEED AP, WELL AP, LFA, etc.). There was a time when we were all talking about this, and a number of firms instituted requirements, but it has been a long time, and I'm curious how it's looking now in 2024. Thanks! 

I am forwarding this request from Kate Simonen from the Carbon Leadership Forum to support a grant application for this research. I don't know if the link will work in this format but if you have questions or want to sign you can contact me or Kate and I can send you the mail with the link my email is:  lstrain@siegelstrain.com     Thanks...

I am very interested to understand the deployment of LED temp jobsite lighting on a national level.  I think this all goes back to the low emitting jobsite.

1. Does your firm utilize temp jobsite lighting on your projects?  

2. Is this every project or a percentage of projects?

3. In your state or area is it prevalent, one... Read more

Greetings,

I'm looking for recommendations from this esteemed group for 3rd-party vendors/verifiers of GHG emissions to support our CSR initiatives. We currently have a provider, but our company has grown to the point to where we need to transition from "analaog" reporting (location by location) to a higher level of service offering (...

Hello, All!  We haven't run WBLCA on a project that may include electrochromic glazing before, and it's embodied carbon footprint is really high in comparison to a more traditional double or triple pane IGU (we thought it would be higher, but this is 3-4x higher).  The EPD we have from Sage Glass for their triple pane electrochromic lists a GWP...
