I am modeling an all variable speed chiller plant and since HAP only provide configuration for constant primary variable secondary chilled water distribution system, I will really appreciate if somebody can provide info on a work around to capture the energy savings from using variable speed drive primary pump. Any comment or guidance will be highly appreciated.

Dear Daniel
If your system is primary/secondary variable please just set it as "primary only, variable". and sum up the W/l/s factor and use average W/l/s factor. It is my workflow
