Retrofitting Office Lighting Controls

摘要

Lighting controls are becoming popular tools for reduction of energy usage and, thereby, reduction of the electrical utility costs in today's office environments. While most codes are not retroactive, some building owners opt to go for the obvious energy savings by reducing the total lighting "ON" time, reaping a secondary benefit of positive publicity by showing an interest in having their buildings become more green and, therefore, more attractive to prospective tenants. This article covers control functions and options; it does not cover lighting control protocols, such as Digital Addressable Lighting Interface (DAU). These topics may be covered in a future article.
