Hey everyone.

I'm doing a LEED project that is connected to a campus central plant. We are using the LEED DES Guide (http://www.usgbc.org/Docs/Archive/Gen... ) and perusing Option 1 -- Stand alone building scenario.

It's clear that anything inside the building must be modeled in the proposed model. With regard to the water systems this includes the heat exchanges and secondary pumps that are located within the building.

My question concerns the baseline model. Would the baseline model also include secondary pumps?

Thanks All, JO

Yes I think the baseline would also be modeled with the secondary pumps. For the building stand alone method it states:

Any system parameters not specifically referenced in Table 3 are modeled as specified in Appendix G. These changes only apply for building equipment serviced by the DES. All other portions of the building shall be modeled in accordance with Appendix G requirements.

See 90.1-2007 G3.1.3.5 Hot Water Pumps and G3.1.3.10 Chilled Water Pumps.
