Increased Task, Reduced Ambient Lighting
Office Lighting: Low Level Ambient Lighting w/Task Lighting vs. High Level Ambient Lighting
A flexible lighting system delivers light appropriate for each task and each occupant, along with a low level of ambient lighting. This practice usually saves electricity when compared with the conventional practice of lighting the entire space sufficiently for most (but not all) occupants and tasks.

Energy Savings Rating:
Limited Assessment What's this?
|1||Concept not validated||Claims of energy savings may not be credible due to lack of documentation or validation by unbiased experts.|
|2||Concept validated:||An unbiased expert has validated efficiency concepts through technical review and calculations based on engineering principles.|
|3||Limited assessment||An unbiased expert has measured technology characteristics and factors of energy use through one or more tests in typical applications with a clear baseline. |
|4||Extensive assessment||Additional testing in relevant applications and environments has increased knowledge of performance across a broad range of products, applications, and system conditions. |
|5||Comprehensive analysis||Results of lab and field tests have been used to develop methods for reliable prediction of performance across the range of intended applications.|
|6||Approved measure||Protocols for technology application are established and approved.|
