Unified Facilities Criteria (UFC)
New Document Summary Sheet
Subject: UFC-3-530-01, Design: Interior, Exterior Lighting and Controls
Description of Change: UFC-3-530-01 is a new Unified Facilities Criteria document that
describes the criteria necessary to create effective and efficient lighting designs for the wide
variety of DoD facilities. It also educates facility designers and managers on emerging
technologies that promise to further reduce the energy consumption of buildings.
Reasons for Change: In 2000, the Illuminating Engineering Society of North America (IESNA)
published the ninth edition of the Lighting Handbook. This edition significantly altered the
lighting recommendations by including a Lighting Design Guide. This matrix addresses the
many lighting issues such as glare and uniformity that must be considered (in addition to
illuminance) to provide a comfortably lighted environment.
In addition, Navy and Air Force facilities follow the US Green Building Council's LEEDTM rating
system and the Army uses the Sustainable Project Rating Tool (SPiRiT). Due to the large
amount of energy consumed by electric lighting in buildings, improving lighting efficiency and
effectiveness contributes significantly to these goals.
Updates the illuminance-based criteria to Quality of the Visual Environment per
current IESNA standards.
Includes daylighting as an important light source.
Updates equipment recommendations for lamps and ballasts to incorporate higher
Impact: Improving the lighting quality of workspaces and reducing the energy requirements of
the lighting system both result in significant economic benefits. The Light Right Consortium
research found that indirect lighting strategies that light the walls and ceiling were rated as more
comfortable by office occupants. Additionally, certain dimming strategies improved the workers
motivation and accuracy on office tasks. Efficient lighting design not only reduces the electricity
consumption for producing light, but also significantly reduces the cooling load that must be
handled by the building's mechanical system. Combining economic benefits of improved
productivity and workforce satisfaction with those of energy savings from efficient sources and
strategies make lighting quality an attractive investment.
Integrates occupancy and daylight lighting controls to reduce energy use.
Emphasizes "effective" lighting strategies that can result in energy savings for
lighting of between 25 to 40 percent, according to research conducted by the Federal
Energy Management Program (FEMP).
