Championing the
Changemakers

Hello! Does anyone know of any general contractors who produce a CSR? Is anyone aware of any general contractors who have an ESG rating? If so, what company is being utilized (i.e. EcoVadis) to get the ESG rating?  

Hello lovely Green Gurus. Hope you all are well. I am wondering if anyone has installed an indoor sports floor that performed well and is low-emitting. This is for a multi-purpose gymnasium at a community center. Any chance?  Thanks All!

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

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
