NC-2009 EAp2:Minimum Energy Performance

DES Option 1 – Streamlined Path

As per DES – Performance path option 1, the DES has to be modeled as purchased energy in both baseline and proposed case energy models. For proposed model, the pumps which are downstream equipment within the LEED boundary shall be modeled with chilled water meter. So, how to model the pumps for purchased energy in baseline case?

Identical to the proposed since those pumps are not regulated by 90.1-2007 without addenda. If you follow Addendum ai instead of DES Option 1 the Baseline pumps are defined there.

Thanks Marcus. So for projects which do not have pumps downstream, can we neglect the pumps energy consumption after modeling in base & proposed model.

You don't model the pumps at all if they are not downstream. You treat the chilled water as purchased energy which arrives under sufficient pressure to not require pumps.
