Is it possible to electrify LARGE buildings? Even in a cold state? What about in a big city? How about a small town?? @MassCEC put VRF heat pumps to the test. 110 commercial buildings later, answers to your most pressing questions.

ANOTHER THREAD: Executive Summary: The technology, industry, and market exist today for VRF heat pumps in commercial buildings. They can offset all heating load in a cold climate and can be configured for small to VERY large commercial buildings.

Can heat pumps be the sole source of heating in a cold climate like Massachusetts? Are whole-home heat pumps ready to scale? 2 years, and 168 projects later, @MassCEC reports back.

A THREAD @MassCEC Executive Summary: yes, whole-home air-source heat is ready for prime time. The technology is there, the demand is there, and the workforce is ~getting there.
