Dear person in charge,
I am Kenta Oshiba from ideaship.Inc. I am consultant company in Japan and I support clients who are seeking LEED certification.
I am wondering how to set up a district heating and cooling system in eQuest that generates energy for multiple buildings in one location and distributes it to each building. My project is to achieve LEED certification for only the portion of the building served by the district heating and cooling system. It is unclear what proporting of the chilled and hot water generated by the district heating and cooling system plant is provided to the LEED project area. If this is the case, how would this typically be set up in eQuest? Thank you in advance for your time, and I would be glad if you could provide me with some clarification.
Best regards,
Oshiba

There are three options for modeled district energy systems (DES) in LEED, as outlined in the Reference Guide:
Path 1. ASHRAE 90.1–2010, Appendix G - Model the proposed and baseline designs using purchased energy according to ASHRAE 90.1–2010, Appendix G.
Path 2. Full DES Performance Accounting - Path 2 is available to projects connected to DES that wish to account for average efficiency across a smaller time step. The energy model scope accounts for both downstream equipment and upstream equipment and requires calculation of the district energy average efficiencies using either modeling or monitoring.
Path 3. Streamlined DES Modeling - Path 3 is applicable for simple district energy systems. The energy model scope accounts for both downstream equipment and upstream equipment and also requires calculation of the district energy average efficiencies using either modeling or monitoring.
You can refer to the Reference Guide for the detailed guidance for each path, which will inform how the DES will be modeled.
