by Jbs051410 f3 — May 28, 2010—The U.S. Department of Energy (DOE) has launched the newest version of its Commercial Lighting Solutions Web tool, expanding energy-saving lighting solutions and approaches to offices and institutional buildings. The first version of the Web tool offered solutions for five types of retail stores.
Developed in partnership with top lighting designers, architects, and commercial end-users, the interactive Web tool provides detailed instructions to help building owners and operators reduce the energy used by commercial lighting by 30 percent or more. The tool estimates energy savings based on project-specific inputs.
Each lighting solution includes a series of “design vignettes,” complete with lighting layouts and component specifications, as well as daylighting design. The vignettes are accompanied by a recommended control scheme and guidance for commissioning.
Users of the Web tool will have a choice of several design vignettes and lighting control strategies that suit the parameters they input for their project. A solution can be implemented as shown or can be used as a starting point for a design that is refined to serve particular corporate branding, or architectural or business objectives.
All solutions are analyzed against a reference building using the space-by-space method as allowed in ASHRAE/IESNA Standard 90.1-2004. Modeled results for each solution included in the Web tool must show decreased energy consumption of at least 30 percent below the baseline design. Some of the solutions have achieved modeled savings of 50 percent or more.
