For conventional ductless heat pumps (mini-split, multi-split VRF systems) the CEC Compliance Manager simulates them as a system equivalent to the standard minimum efficiency split system A/C with a fully ducted system in the attic.
Starting in EnergyPro V8.1, you can take compliance credit for theses systems as a VCHP (Variable Capacity Heat Pump) system. In the case of a VCHP, which requires an indoor unit installed in each habitable room over 150 sqft, we offer the input option at the System level of the Building Tree, Residential tab. Note however that changing the efficiency will not impact the VCHP credit.
You will see them on the CF1R under HERS Feature Summary, and a new section “Variable capacity heat pump compliance option – HERS Verification” on the CF1R, including a comprehensive list of HERS verified measures.
Appendix B of the VCHP staff report is entitled VCHP Compliance Credit—Eligibility Verification Protocols. This document describes the criteria to be met and is available from the newly established CEC website dedicated to VCHP.
