High Efficiency Office Low Ambient/Task Lighting: Large Office

Project Summary

This report summarizes the installation and assessment of an integrated "task ambient" lighting system combined with a reduction of ambient overhead lighting and increase in task lighting, at a multi-story commercial office building in Northern California. Relying primarily on field testing, the project team conducted photometric and power measurements, as well as customer satisfaction surveys and economic payback calculations. This application assessment study was designed to verify the design concept, and technology functionality. The main objective of the assessment was to determine the level of reduction energy consumption achievable via a low ambient, high task lighting strategy using standard off-the-shelf lighting technologies, in order to aid the acceleration of mainstream adoption in the commercial office market end-use.
