[Bldg-sim] Baseline Efficiencies

[Nikola Kravik]

Felipe,
-I think you’re right; Table 6.8.1A shows 9.2 EER which is 2.7 COP on cooling side (sized for electric heat ≥760k).

Felipe:

If I understand you correctly, your Proposed Building has the 500 kW size of heat pump. What goes into the Baseline Case should be the COP based on all of the modeling assumptions from Appendix G and the actual physical configuration of the building, which may or may not be the same size as what is being installed.

Dear All,

I`m modelling  a 3 floor non-building using the appendix G. According to the size and type of the building,  the baseline HVAC system type would be a "packaged rooftop VAV with reheat" (system 6). The proposed building has a heat pump for heating and cooling of about 500 kW. Does anybody knows about the baseline efficiencies for both cooling and heating? I have checked 90.1 standard and it seems that they would be COP 1 (heating) COP 2.7 (cooling). Am I right?

Thanks,
