We´re working on a Resort LEED Project (one owner) conformed by a Hotel, service buildings, SPA and villages, LEED boundary is considering only Hotel and Service Buildings, however, Cooling Plant (3 chillers) will provide chilled water to the whole resort, therefore, is it required to use DES guidance for EAp2 and c1 documentation?

If it is required to use DES guidance, option 2 will be followed, which consists on considering upstream and downstream equipment, we assume upstream refers to all HVAC equipments out of the LEED boundary connected to the Cooling Plant and downstream to all HVAC equipment located into LEED Boundary, including the Cooling Plant (Which is inside the LEED Boundary), Does the Energy Model has to consider the whole project eventhough upstream equipment are located outside of the LEED Boundary?

If it is not required, we were thinking to generate an Energy Model considering only the buildings into de LEED boundary (Hotel and service buildings), a second Energy Model could be generated in order to confirm Space Cooling energy consumption of the rest of the buildings located outside of the LEED boundary and then include this energy consumption on the first Energy Model as a process load. Is this strategy correct?

Thank you very much,

Regards.
