I'm working with a Building that receives 100% of its cooling (chilled water) and heating (steam) needs from a nearby Cogeneration Plant. The Cogen plant feeds various campus buildings. Presently there is no energy meters that measure CHW or steam crossing into the subject LEED building. Is it mandatory that energy meters be installed to meet this credit? Also, instead of metered energy, is there any way we can use eQUEST calculations to determine steam and CHW energy use?
