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? ...

Does anyone know where one can locate weather files (EPW) that has predicted future data for climate change?

Thanks in advance.

Welcome to the quiz portion of Equity in Design and Construction: Seven Case Studies!

Upon completing this course, participants will be able to:


We are pursuing sustainability goals (and documentation of those goals) outside of any certification/rating system for a current project.  However, we have set up a criteria list of goals by following strategies/credits from many of those systems (LEED v4 EPDs, SITES v2 threatened tree species, WELL v2 mindful eating, etc.).  This approach is...

All,

The Idaho Division of Occupational and Professional Licenses (DOPL) has undertaken the Zero-Based-Rulemaking process this year to eliminate all requirements that are not specifically life-safety related.  As such, they have proposed removing the International Energy Conservation Code (IECC) 2018 provisions regarding commissioning...

We should probably agree on the correct spelling for what we at BuildingGreen are calling "BITuser." I noticed that on the Salesforce portfolio screenshot provided by Dennis, it's spelled "BIT User."

BITuser has the advantage of more closely resembling LEEDuser, but it has the disadvantage of looking a little weird in all-caps, as in... Read more

OSB subflooring typically contains formaldehyde, and wood may not be sustainably sourced.

BuildingGreen-Approved Subflooring

Products approved by BuildingGreen contain no added formaldehyde or are available with FSC-certified content.

Magnesium oxide panels, which are particularly insect and moisture resistant, are also... Read more

We're consolidating our office and I find I have back issues of EBN going back to 1999 on the bookshelf. Any use for these other than compost?

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

Hello SCL, 

If you didn't attend last week's SCL Summit, then I'll sum up one of the major takeaways: SCL members NEED TO COMMENT ON LEEDV5. The stakes are high, particularly around waste. 

Luckily, Amanda Kaminsky is making it easy for us. She has drafted a sample comment based on our discussion at the Summit. 

If you have... 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...

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

The results from the "CogFx" study are compelling, showing that people in environments with low VOCs and low ambient CO2 levels score higher on tests of cognitive function.  Specifically, they show that providing 40cfm of outdoor air per (actual live) occupant results in significantly higher scores than even the "Enhanced Ventilation" scheme...

We've been doing some work gathering actual energy data on our recent projects. (In January we actually issued a report on 21 public buildings ). 

One of the biggest issues is getting access to the actual data - many clients don't want to share. 

Has anyone crafted proposal or contract language allowing/requiring design team... Read more
