For those of you working in jurisdictions with both prescriptive and performance-based commercial energy code pathways, roughly what percentage of your projects are using the performance pathway? How do your project teams decide which pathway to follow?

In Minnesota we are seeing very few projects pursuing the performance pathway,... Read more

I just saw this post from Conor on LinkedIn.

Starting in January 2019, all new Columbia Construction Company projects require LED temp lighting.

Are others doing this too? Frankly, given all the benefits and how quickly the industry is matured, it's hard for me to understand why anyone would use anything other than LEDs on a job.... Read more

I'm looking to draft some one-page briefs for my consulting engineers to outline what we would like to see in their specs regarding certain materials and systems.

Columbia already offers access to free EV charging for our field employees. Of the few projects that have have opted in so far, we've had to custom design and intall EV charging setups.

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

Hi Fellow GG: I just wanted to make sure everyone saw the great announcement from the White House yesterday about Code updates to address energy efficiency and resilience.
