Lighting
Goal: Datacenters are typically lightly occupied. While lighting is a small portion of the total power usage of a datacenter, it can be often be safely reduced through mature, inexpensive technologies and designs.
- Objective 1: Use active sensors to shutoff lights when datacenter is unoccupied. Reduce lighting power use and waste heat generation.
- Strategies:
- Occupancy Sensors. Occupancy sensors can be a good option for datacenters that are infrequently occupied. Thorough area coverage with occupancy sensors or an override should be used to insure the lights stay on during installation procedures when a worker may be 'hidden' behind a rack for an extended period.
- Strategies:
- Objective 2: Design light circuiting and switching to allow for greater manual control. Reduce lighting power use and waste heat generation.
- Strategies:
- Bi-level Lighting. Provide two levels of clearly marked, easily actuated switching so the lighting level can be easily changed between normal, circulation space lighting and a higher power detail work lighting level. The higher power lighting can be normally left off but still be available for installation and other detail tasks.
- Task Lighting. Provide dedicated task lighting specifically for installation detail work to allow for the use of lower, circulation space and halls level lighting through the datacenter area.
