I am working in an Office block project (conditioned area- 8500 sqft). VRF systems have been considered for it. The modelling software that we are using is Visual DOE which unfortunately cannot model VRFs. The HVAC baseline for the project is System 4- PSZ HP (Appendix G, Table 3.1.1a). Is it acceptable if in the design case, I consider PSZ system but EER of 13? As VRF is far efficient than PSZ systems, even one with EER of 13 may not match VRF's efficiency. Please provide me suggestions. Thanks.
