Received answers from below questions from NIST Andy Persily

1. Is there a preferred bookends range of CO2 for both “optimal” energy and human performances?

Andy: No

Pipe that delivers domestic water in North America is typically made from copper, chlorinated polyvinyl chloride (CPVC), cross-linked polyethylene (PEX), all of which present environmental challenges. Bimodal polyethylene  (PE-RT) and polypropylene (PP) are potential alternatives with lower climate and health impacts.

We are embarking on our first CLT projects (our at least we hope that they go that way). Would anyone with experience be willing to share some thoughts from the architect's perspective on things to consider, lessons learned, etc?

Wondering if anyone has a contact for good [sustainable] interactive water feature designer? A client is looking for a designer to add to our team and I figured this network would certainly have some insights. Project will be located in Omaha, NE. 

Glazing connects occupants to the outdoors, but with so many opportunities for air leakage, poor insulation, and thermal bridging, glazing is the primary weak link in building energy performance.

BuildingGreen approves glazing that offers strong energy performance properties for a variety of... Read more

There seems to be a slight glitch in that it was posting Seonhee's picture (love Snoopy!) for the post that Duane sent in - is that correctable?

**Just noticed that you can click on the "Edit" tab on the post and correct (e.g. mis-spelled names (Sorry, Seonhee!).**

Do you know something about power purchas agreements, on or off-site?  I understand that they are legal in Washington and Oregon, where most of my projects are, but I haven't come across anyone who has used one on a project.  If you have some experience or expertise, it would be great to hear from you.  

Everyone agreed during last Friday's meeting that we want to call the site BITuser. The question, however, is what domain name should be used.

Whatever domain name is chosen, it will redirect to the actual site URL -- https://bituser.buildinggreen.com (similar to how LEEDuser.com redirects to https://leeduser.buildinggreen.com).

Greetings, Green Gurus:

As unbelievable as it sounds, the Environmental PROTECTION Agency has launched a PR blitz in support of their "new use rule" on asbestos. So the BuildingGreen community needs to push back harder.
