# 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!
