Once you convert to DOE-2.3, you have additional sizing options and other CHW plant improvements. For example:
* For SIZING-OPTION, you can choose the COINCIDENT (simultaneous) peak load of all attached coils, or the NON-COINCIDENT total of all peak coil loads. (Or PRIMARY based on the attached equipment capacities.)
* The SIZING-WINDOW specifies how design-days are treated.
* You can specify the design LOOP-FLOW (gpm) if already known.
* You can specify the RATED-EDB and RATED-EWB for the corresponding coil ZONE:COOLING-CAPACITY.
* You can specify a STARTUP-COOL-DT that sizes the cooling coil based on the space temperature reduction you have to achieve per hour of operation.
