Raising the Bar: Enhancing Education and Guidance of ASHP Selection, Design, Sizing, and Installation

A recent study conducted by the Home Performance Stakeholder Council found that only one third of ASHPs are well-matched with the heating requirement of the homes studied. The remaining units are either oversized or undersized, and savings from ASHP systems are lower than expected. Poor selection and installation practices not only inhibit optimum equipment performance, but they also result in customer dissatisfaction, creating an impediment to widescale adoption.
This session will highlight recent collaborative work by program administrators, manufacturers, trade associations, federal government, and national labs to develop common guidance around best practices for retrofitting homes to meet homeowners’ heating and cooling needs. One project by CEE focuses on design and installation guidance for ASHPs, particularly those in cold climates, with an emphasis on decarbonization objectives and whole house solutions. A complimentary project by BPI is developing an ASHP System Design Sizing and Equipment Selection Certificate of Knowledge. Both of these efforts are working in coordination to help contractors manage customer expectations
During this workshop, attendees will review and provide feedback on the consensus positions established around ASHP system sizing, design, product selection, installation, commissioning, operations, and maintenance.
