Medford Aquatic Center Plan for Energy Efficiency and Solar resources
Energy Efficiency: Natural Gas Water Heating • Recommendation: Design for: Condensing boilers that provide efficiencies over 90% compared to 80% or less for industry standard. Condensing boilers qualify for utility incentives!
Energy Efficiency – Electrical • Recommendation: Design for: Premium efficiency motors, pumps and drives, HVAC and lighting to save power. • Apply to Energy Trust for incentives.
Solar Resources: Plumb for Solar Ready • Recommendation: • Plumb for Solar: Preheat water with solar to reduce natural gas use. Only to be considered on year-a-round facilities. • May not be cost effective at this time.
Water Heating - Solar • Recommendation: Solar water heating can offset natural gas but should only be considered on year-a-round facilities. Natural gas has no “net metering” that banks credit by spinning the meter backward, so solar water heating has to offset actual use!
Solar Electric – Wire Solar Ready • Recommendation: Wire for Solar: Year around savings. Offsets peak demand. Net metering provides savings even when the aquatic center is not used. Currently may not be cost effective. Prices are dropping. • Incentives: Energy Trust: $.75-1.25/watt. Max $150,000
Solar Ready-Electric • Recommendation: Make facility ready for solar PV installation. • South facing roof or solar shade ~27º pitch • Architectural standing seam roof • Conduits and space for inverter
Renewable Incentives: Energy Trust-BETC - Federal • Recommendations: Plan to apply for applicable incentives • Energy Trust-Yes • Federal 30% - N/A • BETC: (BETC new rules 1-1-2012) • Conservation – Yes • Renewable - No
