Drewry Health Center

A lighting retrofit in the summer of 2008 at Drewry Health Center cut electricity use sharply, and updated heating and cooling controls are helping cut total energy use as well. AIRE replaced the boiler in 2009, cutting natural gas use about 25 percent.  In March of 2011, this building earned the County its second ENERGY STAR label, and Drewry also qualified for the ENERGY STAR in 2012. Since 2007, total energy use at Drewry has been reduced by nearly 20 percent.
