Has anyone here found an alternative to XPS for the void former?

A structural engineering contact was included in recent conversations about embodied carbon in insulation materials and brought to our attention that this is a common use for XPS that has nothing to do with its insulating properties. It is typically used where concrete is... Read more

Has anyone had any success with achieving the LEED Building Envelope commissioning points with an alternative compliance path using the requirements of the PHIUS verifier? It seems like an unnecessary duplication to ask the client to pay for a BECx agent and a Passive House verifier. Or am I missing something? I can't find any LEED... Read more

Hi Green Gurus,

In this stressful time, I think it is important for us to continue to feel connected and supported.  Also, it is difficult to come to terms with the reality of what is happening.  So, I thought it would be helpful for us to share some information about the response of our respective firms to the Coronavirus.

Greetings, SDL network - We are attempting to resolve an issue with how data center projects calculate baseline EUIs for the AIA 2030 Commitment and could use some help from this network. With projects that comply with code prescriptively (i.e. not energy modeled), we have found the default baseline assumptions within the DDx platform are not... Read more

Does anyone know of a good summary of state and local energy code adoption for new building and ordinances for existing buildings? I know of this energycodes.gov site, but it feels somewhat misleading when you dig into it. For example, in CO, it suggests there is no min code, but there is, and it doesn’t show the extent to which local govs are... Read more

Good morning SALs! Nicole's survey on restrooms inspired me to post a survey of my own.

I’ve been trying to stay useful lately. I've been posting new writing on the industry, much of it complimentary, over on Roberts’ Green Letter. (Yesterday I posted the mission statement, explained via brand-new-puppy pics.)

I have a 1-minute... 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!

There are so many great contractor-related sessions at Greenbuild this year! I doubt I'm alone in trying to choose between sessions.  

Is there interest in debriefing with SCLers the week after (say Novemeber 9th at 2pm ET?). We could share the golden nuggets from the sessions we attended, saving everyone from wading through the session... Read more
