Revision history [back]

Hi group,

I am new to energy plus. I am working on a two story office building. Initially it is connected with VRF system of gross rated cooling capacity 38776.4 W. Total calculated design zone sensible cooling capacity is 16511.59 W and total user designed zone sensible cooling capacity is 9425.4 W. For this configuration, the electricity consumption is 154 kWhr/m2 building area. Again I increase the gross rated cooling capacity of VRF system to 117500 W. Then the electricity consumption has increased to 244 kWhr/m2 building area. So why the electricity consumption increases when VRF system capacity increases?

Your help is highly appreciated,

Thanks in advance.
