For every Mmbtu of building heat required, 187 kW-hr of electricity is provided free, and 25.6 therms of natural gas are required for production. 0.11 therms of natural gas per Kw-hr is required to
produce additional electricity, if required to meet the building load. 15% of the building electric load is assumed to be provided directly
from NYSEG.
For every ton of chilled water "load", an energy input of 0.10 kW-ton-hr is required for production. 100% of this power is assumed to
come directly from NYSEG.
