Gypsum is calcium sulfate dehydrate, which is mined or produced as a byproduct of flue gas desulphurization (FGD) from coal-fired power plants. FGD gypsum may contain trace contaminants from coal processing, but not enough to represent a hazard to users. Years ago, some imported products created indoor air quality problems that required...

Hi all - I heard from sevearl of you at Greenbuild that you have learned from and perhaps even shared the Path To Zero Carbon series internally at your firms and externally. As I mentioned at Greenbuild, we are attempting to hand off the series to a non-profit, with the idea that groups of experts (including many of you, I hope!) will provide... Read more

Buildings aren’t garbage. But you wouldn’t know it by examining the way the AEC industry works. 

We typically design buildings for a single, limited purpose. We build them partly out of plastics that can’t be readily recycled. We choose diverse materials... Read more

Help. I have a contractor in need of advice on IAQ testing agencies and I'm largely uninformed about the local market of IAQ testing agencies. Anyone have organizations they'd specifically recommend or not recommend?

Feel free to email me directly if you'd prefer - awilson@ayerssaintgross.com.

Good evening,

I am looking for suggestions to replace"wood" siding at the 25-year-old Lyle Center for Regenerative Studies and as always there is no solution that does it all. There seem to be three main options: wood, composition siding, or fiber cement siding. I am looking for something with low embodied carbon, little maintenance,... 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...

Anyone aware of tools or workflows for modeling of a specific outdoor space and effective surface temperatures?  We've done a goodly amoutn of microclimate simulations, but never explicitly factored in the ground surface, in terms of emissivity and other related factors.   

Has anyone used the new 3M Smog-Eating Granules on a roof before? Malarkey and Soprema are offering this as an option for their roof shingles. Seems like a great technology for urban areas, but I'd be curious to see if anyone here has actually successfully specified and installed it.

Hi All! 

We have had a few multi-family projects consider this single package vertical unit with integrated ERV, but we haven't pulled the trigger for fear of the unknown. Our local engineers aren't sure how it actually performs and worry it may not meet code requirements for separation between exhaust and intake. Has anyone else used... Read more
