Lighting controls are required on new construction projects according to the size and purpose of the space. Controls range from a simple switch that allows occupants to control lighting in a space to remotely programmed controls that automatically add or remove light.
Indoor and outdoor controls are necessary and often mandated. California has some of the more strict requirements. Parking lot lighting is reduced when the store is closed to save energy. Indoor lighting needs to respond to load reduction requirements during peak demand. If a commercial building is greater than 25,000 square feet skylights must be used. All of these requirements make sense in the context of sustainability.
Lighting controls allow different scenarios depending on the time of day and activity being performed in the store. Pre-Open, Open, Closing, and Closed settings match light levels to the needs of the store schedule. How many times have you seen lights burning an hour before open of after the store is closed? Controls help eliminate that waste.
Installing lighting controls can result in a savings of 8-15% savings on utility bills. The results are so significant that some utilities offer rebates and incentives to help offset investment cost.
