Lighting Project at Green Library

The Green Library recently implemented an upgrade to Green East through the Energy Retrofit Program(ERP), incorporating LEDs and lighting sensors for the stacks to save energy. Thanks to the sensors, lights are no longer left on for hours until the library closes, and they go on only when the aisles are occupied. The LED upgrades improve energy efficiency, provide better visibility for librarians, staff, and students, and result in fewer maintenance costs. The annual cost savings is estimated to be nearly $11,000, with an approximate 65% reduction in usage for these light fixtures, saving more than 75,000 kWh annually.
