Final Research Summary Report: Rooftop Units FDD

Report / April 23, 2013 / Advanced Buildings, Deep Energy Retrofits

This report summarizes the findings for the Rooftop Unit FDD project within the Evidence-based Design and Operation research program. The project goals were to reduce the energy performance degradation in rooftop HVAC units (5-50 tons in size) in California and support the persistence of energy/demand savings from utility-sponsored HVAC service programs and high efficiency unit programs. Key short and longer-term benefits were achieved in this project.

This report was prepared as part of the California Energy Commission Public Interest Energy Research (PIER) program.
