Hey everyone, 

With the coming In-Use Off-Road Diesel-Fueled Fleets Regulation | California Air Resources Board we have been doing some research on availability of R-99 fuel prior to the January 1 start date. One thing we aren't finding in the research is an estimate of cost impacts. Has anyone started rolling out R-99 on their sites yet... 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.

THIS WEBINAR PURCHASE AND REGISTRATION IS CLOSED.

Should housing be affordable? Or should it be sustainably designed, built, and operated?

When you put it like that, the question sounds absurd.

But the idea—usually unspoken—that sustainability wastes precious time and resources is painfully common in the... Read more

If only a few of the Best Practices will have checklists, which will be included under the "Implementation Toolkit" tab, I'm thinking we can simplify them (compared with LEEDuser).

I've attached a screenshot of a LEEDuser checklist. But I don't think BITuser will need the four types of icons, and the legend will take up more space than... Read more
