Hi Iam trying to see the change in consumption due to the Weatherization(Energyplus). ( variation in R value and the infiltration variation is bit higher). I used the PNNL model for Single Family. The Heating and cooling coil capacity is "autosize ". Hence iam seeing a change in both the pre and post models capacity and so the the change in energy consumption is higher. To get the change in consumption for the Weatherization alone Iam planning to hard size the post IDF with the values from the pre run EIO values. is the approach correct? if i want to make the HVAC setting same in pre and post then need to change the "autosize" to values from Pre run So which are fields to be changed? 1. Sizing system :- I changed the cooling and heating design capacity 2. cooling coil DX single speed :- I changed the Cooling capacity 3. Coil Heating Fule :- I changed the Nominal Capacity 4. AirloopHVAC:UnitaryHeatCool :- Changed the cooling and heating supply air flow rate all these fields from "autosize" to value got from the EIO of the pre run.
Is the changes correct so that both the system is identical ? Should I change anything other fields?
