Title | Lighting Management for Energy Savings

Content
Nationally, energy for lighting accounts for up to 20% of all U.S. electricity use. The lighting of offices, hallways, reception areas, and other spaces constitutes the largest use of energy in most office and commercial buildings—about 35%. This proportion increases even more when the energy needed to cool the heat generated by all the lighting

systems and when electricity used for lighting outdoor parking and public areas are factored in. Yet, good lighting is essential to provide worker productivity and occupant

comfort indoors, as well as to ensure visibility and safety outdoors.

The design, commissioning, operation, and maintenance

of a building’s lighting need to be considered as an integrated, functional system to achieve maximum utilization and to control factors that affect system efficiency. Operation and maintenance practices for indoor and outdoor lighting systems must also be considered an important and integral part of the building energy efficiency equation. Newly available lighting and control technologies also require building lighting maintenance personnel to stay informed to get the most out of existing systems, as well as identify new technologies that can help improve O&M practices.

Building maintenance engineers and maintenance staff

face a difficult task in trying to keep costs low while balancing occupant lighting needs with equipment efficiency. A building’s lighting quality has a direct impact on occupant satisfaction and may outweigh the cost of lighting, especially in public spaces. Similarly, a reduction in some public and outdoor area lighting may result in safety concerns, and can cast a negative light on all efficiency measures.
