Hi folks,

Wondering if this group has insights about the low-embodied carbon product "Vertua" from Cemex, which appears to be a proprietary concrete product launched in 2020.

Our client wants to use CarbonCure; but our likely concrete sub is saying Cemex (where they typically source their concrete) offers an alternative called... Read more

Hi all,

Looking from insights from anyone who's been through WELL certification before - we've got a lab/office project pursing WELL down in Florida that is struggling to meet the turbidity level requirements of the WELL W01 prerequisite, specifically with the hot water supply, and we're not sure how to best remediate the issue.  Should...

We are working on a project in the Midwest that involves taking down and replacing an 100-ish-year-old brick building.

At Living Future last week a woman from Google asked about cost comparisons and I shared that the City of Santa Monica conducted a study analyzing the costs of a prototypical mixed-use project for a Living Building vs. LEED v4 Platinum vs. code compliant (Title 24, part 6).

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? ...
