Hi,

I'm simulating a 10-story office for LEED ID+C certification ID+C. I'm usind System 8 for the Baseline and according to ASHRAE 90.1/2010, the building have less than 300 tons. So the number and type of chiller will be "1 water-coolled screw chiller. In addition, according to ASHRAE: "Chilled-water pumps in systems serving less than 300 tons cooling capacity shall be modeled as a primary/secondary systems with secondary pump riding the pump curve".

My question is how to create in OpenStudio a "1 water-coolled screw chiller with a primary / secondary pump systems with secondary pump riding the pump curve. I am unable to find an explanation of what this "secondary pump riding the pump curve and screw chiller" would be. Can anybody help me.

Thanks!
