E+ vs. IES: Loads Results comparison
I am trying to do a comprehensive analysis between the two software, IES VE and E+ (Grasshopper), regarding the Zone Loads. I know that a diffrent method is used for IES (CIBSE) while E+ uses other standards. So far I managed to model and simulate a test building, with the same inputs in both. The results I am getting are diffrent by 9%. I am trying to compare the inputs/outputs and for that I need to get from E+ the following:
-Air temperature (°C)
-Dry resultant temperature (°C)
-External conduction gain (kW)
-Internal conduction gain (kW)
-Air system input sensible (kW)
-Aux vent gain (kW)
-Infiltration gain (kW)
-Natural vent gain (kW)
-Space conditioning sensible (kW)
-Steady state heating plant load (kW)
-DHW heating demand (kW)
I am guessing that:
-Air temperature (°C) --> Setpoint
-Aux vent gain (kW) --> Heatgain rate from DOAS
-Infiltration gain (kW) --> Infiltration Heat addition (IES has negative values for certain rooms while E+ has zeros)
But I am missing the rest ..
Hope this makes sense :/
Thanks in advance!
