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.

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

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

Thanks in advance.

Hello all, 

Any Fitwel experts out there? I have a 30,000 sf boutique hotel + spa client who would like to certify under the Fitwel rating system but Fitwel folks are telling me that no scorecard is currently available to hotel clients (can't use mulit-tenant or resi, that a hotel scorecard is under development). Has anyone used Fitwel... Read more

I'm looking to compile an outdoor weather station for a local project, and we'd like to add local outdoor CO2 information to our data. I usually work with Onset HOBO products, but they don't offer an outdoor CO2 sensor. Their weather stations can take data from any CO2 sensor with an analog output - does anyone have any suggestions?

A new article addressing whether PFAS finishes on upholstery fabric actually work (Spoiler alert - they don't) has been published and can be found here:
