Session DescriptionIn New England there’s been dramatic increase in the use of ductless (and ducted) air-source heat pumps, also known as “mini-split” heat pumps,. This session provides an opportunity to learn about cold climate heat pumps from an expert in HVAC and building science. In this session, we’ll present a case study on measured performance of a single installation in southwestern Vermont. We’ll talk about a range of heat pump applications, do’s and don’ts, and the basics of spec’ing and sizing heat pumps. We’ll look at the results of some recent field research, as well as some ongoing codes and standards work. This session will include plenty of time for question and answer, so if you have heat pump experiences or issues you’d like to make sense of, please bring them along.  BIOBruce Harley is a recognized expert on energy efficient residential construction and retrofit.
