Re: [EnergyPlus_Support] what is in the HTML report for Cooling and Heating energy


when you specify chiller or boiler you provide supply and return water temperature. These temperatures should be synchronized with variables csv (to find the biggest Power in csv and copy data from this row to idf chiller:electric, boiler). This should solve the problem

 Thanks, Artem. Which delta T are you talking about? For the whole year energy consumption, why wouldnt they just sum up the energy for each equpiment that is readily available for each time step's calculation?

It is because of different delta t. In html it took rated delta which you specify in idf. In csv it took real dt.
just make the equipment not auosize, but hard size and adjust delta t to make it equal to reality. Then you will get adequate result
