Anyone know of tools/methodologies for estimating embodied carbon and carbon sequestration potential of individual green infrastructure projects (e.g. bioswale along bikeway)? I've seen tools for the larger scale (e.g. land use change) as well as specific to trees (e.g. i-Tree), but these don't fully meet my needs.

Thanks!

Just had a contractor call who said they had a university client interested in using natural-gas-fed fuel cells as an alternative to grid power in some applications.  They were interested in an intermediate scale: 300kW.

Anyone with any experience with these devices?

HI All,

I have been tasked with putting together a cost comparison of doing a LEED v4 Gold building vs. making that same building Passive House. Obviously they are two different systems, with two different outcomes, and it's not really intended as a total apples to apples cost comparison, but more a value comparison for a developer....

Hello everyone,

Hi all, are there requirements to include/submit backup documentation to the CC excel template? Or is it just the template itself that gets submitted? The question is coming up from our leadership over what documents are public vs internal.

BuildingGreen-Approved Systems

BuildingGreen approves mini-splits that are tested to AHRI standards and have minimum SEER and an... Read more

Hi everyone -

I'm writing to conduct an informal (and unscientific) poll about the green certifications achieved by office spaces (main or branch) for Green Gurus firms. SERA is preparing to embark on the journey of finding, designing and inhabiting new office space, and we're interested to hear and learn from your experiences,... Read more

What is the status of the roof insulation market regarding non-halogen containing polyiso boards? I know GAF and Atlas still have them. I thought JM had them as well, but seems to have taken them off the menu. Are there performance issues?
