The U.S. Environmental Protection Agency (EPA) developed this Building Upgrade Manual to assist organizations in planning and implementing profitable upgrades. This manual outlines a process for developing a comprehensive energy-management strategy and an integrated approach to upgrading existing buildings. It also provides information on proven energy-efficient technologies that can produce energy savings of 35 percent or more. Chapter six of this publication is devoted to issues related to lighting.
This report summarizes the findings from research conducted at NREL to assess the technical potential for zero-energy building technologies and practices to reduce the impact of commercial buildings on the U.S. energy system. Commercial buildings currently account for 18% of annual U.S. energy consumption, and energy use is growing along with overall floor area. Reducing the energy use of this sector will require aggressive research goals and rapid implementation of the research results.
