I'm looking to draft some one-page briefs for my consulting engineers to outline what we would like to see in their specs regarding certain materials and systems. For example, letting the plumbing and civil engineers know that we prefer to eliminate PVC pipe and want them to specify alternatives like Polypropylene, cast iron, ABS, etc. The idea... Read more

Hi SCL, 

Just thought I would share an interesting piece from Construction Dive about a lack of guidance on when to halt work due to bad air quality--from wildfires or otherwise. A few SCL companies are mentioned here as having their own policies, but I was pretty shocked to learn that this isn't required by OSHA.

This might be going down a rabbit hole, but in moving to California this year I noticed that "zero net energy" (ZNE) is the standard term, whereas "net zero energy" (NZE) was more common back east. The DOE's 2015 definition (below) uses "zero energy building" (ZEB), which to me implies a building uses no energy at all.
