A lot of small firms would like to sign the AIA 2030 Commitment (we had 100 in a room in 2022 in a session led by Nadav and Gwen Fuertes). But we have learned that a) they don't have a good way to energy model small commercial to... Read more

Hello- If you use Procore....

Are your jobs using a template to conduct and create "reports" of their IAQ inspections? Did you set it up in forms or inspections? Would you mind sharing an example template with me? I know Green Badger has a great app to do this, which we use. We would use inspections in Procore for jobs that are not using... Read more

But PVC has its issues and neither PVC nor PEX are recyclable (especially if... Read more
