2020-10-01 18:33:40 -0500 marked best answer Why is the coil, chiller, tower oversized in Energy-Plus ?

The total cooling load of the entire facility is only 2700 kW, however the autosized design coil load is 8600 kW, the nominal capacity of the chiller and tower are 8600 and 8100 kW respectively. There is no sharp changes in design day schedule. Yet, how does this oversizing occur ?

2020-10-01 16:12:46 -0500 marked best answer Design day and Runperiod value mismatch

This particular CSV file (Please refer the image) was obtained from an EnergyPlus Simulation. The design day for this simulation is 05/21. The run period is also 05/21. Hence, both of them are same.

I take it that the variables in the upper half of the CSV file which is enclosed in a red box, corresponds to the design day values, and the rest belongs to run period.

So, I was wondering why they both are not the same ? eventhough my run period and design day are same!

2018-09-27 23:03:30 -0500 marked best answer water heater sizing object missing in OpenStudio

I am trying to add a water heater and I am trying to autosize the heater maximum capacity but it says

Warning ** Water heater named WATER HEATERhas heater capacity set to AUTOSIZE but it is missing associated WaterHeater:Sizing object
   **  Fatal  ** GetWaterThermalTankInput: Errors found in getting thermal storage input. Preceding condition(s) causes termination.

However, the fatal error disappears when I hardsize the heater maximum capacity. I believe this is a OpenStudio bug, can anyone clarify ?
