KVCC Sustainable Agriculture Building
Kennebec Valley Community College- Sustainable Agriculture Lab Building
General Energy Use, Strategies and Systems
Energy Use:
Sixteen (16) closed loop geothermal wells were provided, each at 340 feet deep. The wells provide approximately 34 Tons of cooling and 320 MBH of heating.
The PV array is sized for 195,000 kwh/yr, to offset the expected 104,000 kWh/year in building energy use, and well as energy consumption of (2) propane fired kitchen ranges.
Energy Strategies:
Mechanical system provide heating and cooling via distributed water to air heat pump. The building ventilation was provided with a dedicated outside air unit (DOAS) with an enthalpy type energy recovery unit. The DOAS also had an integral water to air heat pump.
Lighting was predominantly energy efficient T8 with LEDs used for downlights and exterior lighting. T8s proved to have a long payback compared to their relatively low initial cost for general use linear fixtures.
