If your school is looking to replace a chiller, boiler, rooftop unit, or building controls, DOE recommends consulting the newly released school efficiency enhancement guides from DOE and Lawrence Berkeley National Laboratory. The guides contain information on energy-efficiency measures that you can take in conjunction with the four identified upgrades your school is already making. Schools can consult the guides to find performance requirements for energy efficiency, energy savings, and implementation costs to support school facilities staff involved with the planning, design, and specification of infrastructure upgrades.
