Hello,

TPO is an obvious alternative that is less toxic, but it has some performance concerns and can often lead to leaking (not... Read more

Does anyone subscribe to Green Badger? Do you find it valuable?

Does anyone here have a draft spec for low embodied carbon concrete they could share? I see the GSA has a standards sheet with MGWP limits, but we are hoping to actually specify the mix for upcoming projects.

Through our conversations, it came to light that ILFI considers the LBC Red List threshold to be 10,000 ppm, rather than the 100 ppm written into the... Read more

Practitioners interested in reducing the embodied carbon of buildings are likely now used to considering the impact of different materials, like mass timber or low-carbon concrete. Low-carbon construction, however, may be less familiar.
