Section 901.5.1.3 of the 2018 IgCC includes a requirement that "A critical review shall be performed by an external expert independent of those performing the LCA."  I'm curious as to what other's experiences are with having an external expert review an LCA - how does one find such an expert?  Do you have any favorites that you'd recommend? ...

Kristen Fritsch, in the thread about ipe wood, asked about resources comparing the carbon footprint of transporting building materials vs the transport mode.  There are people who spend their lives on this topic that I won't presume to speak for, but I'll share a few observations:

Even though freight transport is something like 7% of... Read more

Just an FYI that BG's web team is planning on attending your meeting at 1:00 EDT. We will need information on how to join since the info in the invite didn't work last time.

See you all then.

Friends,

We put a lot of effort into air tightness design, detailing, and construction administration, often including 6-sided mockup and parital or whole-building blower-door testing.  For commercial buildings, these tests measure air leakage in cfm/sf at 1.57 psf (75pa).  

I came across this research paper several years ago, but... Read more

Our all-volunteer Advisory Board helps BuildingGreen identify the most critical topics for our coverage, and directs our research as we investigate these topics and bring them to our readers. Their distinguished and varied service in the field of environmentally responsible building is an inspiration.

There has been some great press in the last couple of days related to Healthy Building Network's (HBN) newly released report "Chlorine & Building Materials Project".  That report is over 200 pages long, but there is some great commentary available that makes the top issues much quicker to grasp.

Chlorine is used to make PVC and PVC... Read more

Friends, I reviewed the firm's 2019 AIA 2030 data with a Principal, having organized the data in such a way that we could manipulate it. I included the average EUI and weighted EUI, since the latter gives a truer picture of where we are as a studio. In the past, the assumption was we would raise all boats with efforts to improve our practice in... Read more

Dear all,

For a specific existing building application, we are looking for a half inch insulating glazing unit, preferably with low-e coating. Based on my research, 5/8" seems to be doable (1/8" glass + 3/8" air gap + 1/8" glass) but I'm yet to find a viable 1/2" solution. Have you come across any on your projects? Thanks for your...
