Top Since installation in 2008, the three photovoltaic arrays on this building and the other two buildings have generated 153,863 kWh of electricity (as of Aug. 24, 2011). Above This four-panel solar hot water system preheats domestic hot water and provides a 30% annual energy reduction over a conventional gas-fired water heater. generated 153,863 kWh of electricity — enough energy to power 3,071 homes for one day. Internet users can observe current and historical performance data of the photovoltaic arrays at http://tinyurl.com/GoldenHillPV. Other recent energy-efficiency upgrades to Golden Hill include a new elastomeric reflective roof enhancement to seal and cool the roof, new high-efficiency T5 lighting with occupancy and daylight sensors in a number of tenant suites. Bringing things full circle, NREL now occupies several tenant suites in Golden Hill, and the presence of such a high-profile green energy institution in the complex has further raised energy consciousness throughout Golden Hill. Golden Hill continues its quest to improve energy efficiency. Plans include installing higher efficiency boilers, replacing the original pneumatic controls with direct digital controls, and implementing an energy management system. Another energy-saving solution in the works involves revising the cooling towers’ pumps and piping to decrease piping friction and eliminate the need for a secondary cooling tower pump. This strategy is anticipated to reduce pump energy by approximately 75%. • About the Author Mike Kamen, LEED AP is a technical writer , with The RMH Group in Lakewood, Colo.
