David M. Keith, Principal

David Keith is a lighting consultant with over twenty years experience in design, project management, research and education. He has participated in a wide range of projects from residences and retail to roadways and research facilities. This includes working for private and public clients on a variety of projects which lasted from one hour to years. His background in architecture and construction enhances his ability to coordinate with other members of the design team, to develop projects that succeed.

Academic experience includes undergraduate studies in architecture and a B.S. in Architectural Engineering (1985) and a M.S. in Civil Engineering (1995) from the University of Colorado in Boulder.

Lighting design clients and projects include the Boulder County Courthouse Plaza, Boulder Community Hospital intensive care facilities, The Way Station outreach center, terminals and concourses at Stapleton International Airport, interiors and roadways at Denver International Airport, the National Western Stock Show Arena, E-470 roadway lighting and maintenance facilities, Jefferson County's Columbine Library, Leanin' Tree Museum, Gateway Park outdoor entertainment facility, and McGrath and Lillie's BASIS research facility. David has also worked with Public Service Company of Colorado, providing consulting services for Demand Side Management programs, and with the Colorado Department of Transportation on numerous projects, such as the design for the entire I-25/I-76 interchange, the lighting of State Highway 119 from Black Hawk to US 6, improvements to the intersection of I-25 & 120th Avenue, lighting for the Hogback Park and Ride facility, and additional lighting for the interchange at I-70 and C-470.

David has been an active volunteer addressing lighting issues, principally with the Illuminating Engineering Society of North America (IES), working at the local and international levels. He served in IES as president of the Rocky Mountain Section in Denver, and as Regional Vice-President for the Rocky Mountain region. Since 1987, he has been a member of the IES Roadway Lighting Committee, recently serving as chairman of the Fundamentals and Education subcommittee. He worked with the Colorado Office of Energy Conservation in 1997 on the "Energy Guidelines for Commercial and High-Rise Residential Buildings in Colorado", serving as the representative for the local IES section. He is a member of the IES Educational Review Council and contributed to the current Lighting Fundamentals text, in part as principal author of the 1999 revision to the section "Lighting Applications for Exterior Environments". He is a founder of and contributor to the Alliance for Lighting Information, a website addressing lighting issues, as well as technical advisor to various organizations including the Lighting Research Center, the Denver Museum of Nature and Science and the New York State Energy Research and Development Authority. In 2002, David was honored as a Fellow of the IES, and also served from 2003 through 2006 on the IES Technical Review Council.

Lighting research experience includes working with the Electric Power Research Institute on the Advanced Lighting Systems, evaluating the potential of integrated office lighting controls [JIES v26n1], and developing a prediction tool for peak occupancy of offices [JIES v28n1]. This research was extended through work with the Lawrence Berkeley National Laboratory on refining methods for predicting energy savings. David also has done development and research into roadway lighting optimization and the reduction of energy use and light pollution [JIES v29n2, JIES v31n2 and two in JIES v32n1]. Along with J. Knox, David has also worked to develop and present papers addressing the atmospheric scatter of light into skyglow (2003 IDA Conference, 2008 CORM) and modeling the interaction of surfaces and sources for color perception (2003 IESNA Conference).

David has talked about lighting with people at all levels, from beginners through professionals. He has taught classes on light and color to students ranging from grade school to college art students, and entire courses on lighting and design to interior design students, engineering students and professionals. For more than ten years, David has served as Education chairman for the Rocky Mountain Section of the IESNA and he helped develop the particular ED-100 Lighting Fundamentals course that he and others have taught in Denver since 1994. He has also taught most of the sections of the IESNA ED-150 Intermediate Lighting course. Both courses are accredited by IESNA and other organizations as continuing education for professionals in lighting and related fields. David has made presentations at numerous meetings for a variety of organizations, including the International Dark-sky Association, Colorado police officers, AIA, IEEE, the IESNA Annual Conference and the IESNA Street and Area Lighting Conference. In 2003, the IESNA Roadway Lighting Committee recognized David’s presentation on light sources and atmospheric scatter as the most outstanding of the year. From 2005 through 2007, David taught in the interior design program at the Rocky Mountain College of Art and Design, and in the spring semester of 2008, in the illumination engineering program at the University of Colorado in Boulder.
