90.1-1999 energy standards would have been $3 per square foot ($68,000/year),
the estimated energy cost for the Epi-Center is $0.56 per square foot
($12,732/year). A 45-kilowatt photovoltaic system was designed to produce
58,000 kWh of electricity per year, 156 percent of the building’s electrical energy
needs and 32 percent of its total energy needs. Ceiling fans, operable windows,
and exhaust fans will be used for cooling since there is no refrigerant-based cooling
system in the building, a measure that will reduce the total electricity use by
65 percent.*
