BELOW: Craig Jay, director of facilities for the Garfield Re-2 School District, points to a boiler system at Coal Ridge High School that the district was able to make more efficient by reducing the temperature of return fluid to design specifications so it condenses properly. Coal Ridge High School reduced its energy use by more than 10 percent for the first six months of the past school year.
