Dear all,

We have a school campus project (LEED NC MB) in Shanghai. The cooling source is from central cooling plant and the heating source is from Municipal steam. We want to use option 2 according to the DES guideline.
My question is how to model the heating source in baseline and proposed model. Both steam meter or hot water boiler? If use hot water boiler, how to determine the average efficiency?

Waiting for your feedback.

Best regards
