I am sure there are others trying the same thing, yes... maybe?! ... Read more

Greetings Gurus, following the AIA COTE Design for Economy concept, does anyone have a resource for a list of building efficiency ratio "targets" by space type? I've always struggled with this initiative. 

Are FSC glulams available? By many manufacturers? Which ones?

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. It's good that we're doing this, but it won't scale quickly enough and cost effectively.  I think a practical next step is working with trailer companies so... 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. For example, letting the plumbing and civil engineers know that we prefer to eliminate PVC pipe and want them to specify alternatives like Polypropylene, cast iron, ABS, etc. The idea... Read more

Instead of endless bounty, climate change is bringing us catastrophic droughts and flooding that now dominate the headlines and threaten entire regions.

This report covers innovative... Read more
