Solar PV, Cool Roof and Lighting Upgrade at 114th Precinct

In partnership with NYPD, DCAS Energy Management has led three complementary GHG-reduction efforts at the 114th precinct in Astoria, Queens. This month DCAS will kick off installation of a thirty seven (37) kilowatt solar photovoltaic (PV) system on the roof of the 114th precinct. This PV system is one of eight rooftop solar PV projects funded by a federal stimulus grant program administrated by the New York State Energy Research and Development Authority. The PV system assembly includes several small inverters, a data acquisition system (DAS) with web-based monitoring software, a ballasted fixed angle racking system, and approximately 152 PV panels. The PV system will provide electricity to the precinct’s main electrical distribution panel and will save the City an estimated $20,000 in avoided electricity costs each year.

In 2009, the precinct’s roof became one of the City’s first Cool Roofs. Cool or white roof coating helps lower the ambient temperature of the roof, which reduces cooling loads and will help the new PV system perform even more efficiently in the hot summer months.

The third energy-saving project is a comprehensive lighting system upgrade that will improve the quality and efficiency of lighting in locker rooms, hallways, offices, stairways, bathrooms, cells, mechanical rooms, a gym, storage spaces, the garage, and on the exterior of the building. The lighting project will cost $182,000 and will reduce the precinct’s electricity bill by $24,000 annually. The more efficient lighting will reduce annual energy use by 181,000 kwh and GHG emissions by 64 metric tons annually.

Together, these three measures will save the City $44,000 a year and reduce GHG emissions by 81 metric tons annually.
