We are looking into different building skin materials from including GFRC and FRP (amongst others) as alternatives to precast. I remember years ago (when I was at LAS) we had retrofitted a Federal Courthouse with FRP for blast resistance. I kind of remember that at the time it had some pretty high offgassing concerns. I haven't been able to... Read more

Hi Leaders,

We've pulled together some highlights from each of the three half-day cross-network workshops that happened in October. This report captures the gist of each workshop:

We broke up into 5 discussion groups by market sector:

Here are the proposed "guiding questions":

Preservative treatments extend the service life of wood, but many such treatments are highly toxic, especially to aquatic life.

BuildingGreen-Approved Preserved Wood

Products approved by BuildingGreen use chemicals (commonly borates) that are relatively low in toxicity and have low VOC emissions.

Health and Environmental... Read more

Hi everyone,

As you may know the ICC has changed the way the IECC will be written in the future and most of us think that will reduce the stringency of the future energy codes that are the biggest lever in the fight against climate change within the buildings sector.

So one of the best pathways forward is via ASHRAE, which has a... Read more
