Description

Good lighting should be responsive to the visual needs of the user. But the user also has economic needs. With the dramatic growth in solid state lighting, the use of economic tools and rigorous financial analysis becomes more important than ever. Selecting a new lighting system, with a less familiar technology, is an important and difficult task for the lighting professional. The designer needs to make sure that the proposed lighting system meets or exceeds IES recommended practices, complies with energy code power limits and control requirements, and is able to meet extra targeted goals for the building, such as LEED, Advanced Energy Design Guides, or other local or project standards. But at the most practical level, any new lighting equipment selection needs to make sense economically
