Electric Lighting and Controls

Good lighting is usually an intelligent blend of natural and artificial light. Specifying the right lights and fixtures, laying them out well, including good controls, and making the system easy to maintain are all crucial for energy efficiency.

Electric Light Sources

The choice of light source is very important, both for visual comfort and for energy efficiency.

Light Fixtures and Layout

Light fixtures and layout can be as important to good lighting as the light sources themselves.

Controls for Lighting and Daylighting

Lighting and daylighting controls are systems that adjust the amount of natural and artificial light in a room, based on its brightness, occupancy, and other factors.

Lighting Operations & Maintenance

Lighting operations and maintenance ("O&M") are the practices that keep lighting systems working at peak performance during the life of the building.
