I’ve heard two people at NASA resigned/stepped down before they finally got to someone that would send this email there. (Janet Petro is the one who would, not sure who didn’t.)

That’s not how it actually works though - and is a common misconception. See here for some references from the US DoE and others (easier than putting them here on my phone).

Basically, it’s not super inefficient to heat the house back up and being at a higher temp (and increased gradient to outside teml) is harder to maintain and uses more energy overall.
