I'm looking into using solar shingles as a roofing option for a historic building renovation. Has anyone used them before and have any recommendations? I understand they won't be as efficient as traditional panels, but I'd like to figure out if it would be a worthwhile compromise to discuss with the historic commission, if necessary. Thanks...

I'm just wondering if anyone is using GBCI's Better Materials site as their go-to source for transparency and healthy materials.  Having all the search engines on one platform is great in theory, and I keep hoping that it will be the one-stop site/resource that I can get all our designers to use.  Unless I'm missing something though, it still...

Hey gang,

We're working on a project that's currently designed as mass timber. We're up against some cost control efforts (of course) and the CM/Client is asking about changing some of the building to steel or green steel.

I am going to move slowly to ensure my next chapter is the... Read more
