Project is utilizing energy from a central plant, the team is attempting to decide between using the purchased energy approach vs. modeling the plant. The project is LEED v4 and follows ASHRAE 90.1-2010; if the central plant does not comply with 90.1-2010 is the "model the plant efficiencies" no longer an option? If the central plant does not meet 90.1-2010 does that disqualify the entire project?

The central plant provides domestic hot water, chilled water, and heating hot water to 2 buildings on a campus through underground piping and pumps. The plant utilizes a series of water cooled centrifugal chillers, cooling towers, gas fired domestic boilers and gas fired hydronic boilers. Electrical is stepped down through the central plant and distributed to the 2 buildings, but is not generated by the plant. The central plant is under separate construction contract from the 2 campus buildings.

Based on your description I would say no it does not need to comply for LEED assuming it is outside the LEED project boundary.
