Lighting accounts for nearly 20% of the total electricity consumption of commercial buildings in the United States. Effective lighting systems involve the integration of lighting technologies with the building as a whole – across the lifecycle of a building. Green technologies and design strategies are more conducive to energy and financial savings, and improved human health, productivity, and satisfaction.

Lighting choices in offices affect:

  • Comfort and mood of workers and visitors

  • Up-front costs of lighting equipment
  • Utility and maintenance costs
