Dear Green Gurus: I'm so sorry to have missed seeing many of you at AIA last week. I heard the BG and COTE events were the highlights of the week! Congrats.

I'm sure by now you've heard of the dreadful Supreme Court decision about the EPA. I thought I'd share a helpful, if not sobering, perspective in an Op-Ed today in the Washington... Read more

Hi folks,

I'm looking into lower-carbon pipe options for HVAC and plumbing. The MEP 2040 has slides from a Buro Happold study in 2020 showing PEX to be much lower in embodied carbon than copper, which is unsurprising. CPVC is also a lower-carbon option.
