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.

Hi folks,

I hope you're all doing well, despite the heat (thermal, political, social...ugh!).

We've had low turnout on the SAL monthly calls lately; it seems that these aren't a high priority for many of you. That's not necessarily a problem, if you're finding value in being in the network for other reasons, that's fine.

We... Read more
