Should we be trying to electrify everything? Is it practical for existing and new buildings with the technologies we have now? Two engineers with different takes on these questions will debate electrifying residential buildings, from small single-family to high-rise apartments. Both speakers have years of experience with heat pump technologies (mini-splits, PTHPs, water-source HPs, VRF, and several types of heat-pump water heaters). They’ll present examples of buildings where these systems worked wonderfully, where performance was less than ideal, and a few absolute failures. Too often, building professionals – designers, engineers, contractors, building owners/operators, utilities, and even manufacturers – don’t fully understand how these new systems work. Come  learn from others’ mistakes, understand how these systems can be used well, and consider: Are there buildings where electrification doesn’t yet make sense?
