The project is wide-ranging. Four residence halls will get new HVAC and hot water systems. The academic and administrative buildings will get LEDs and sensors that turn off lights when rooms are unoccupied. A computer power management system will put PCs into a deep sleep mode when they are not in use for a long period of time, which is an energy saver. The press release also says that 12 buildings will receive water retrofits.
The retrofit will consume 4,000 man hours of work and is expected to be completed by next summer. The annual cost savings will be about $145,200, which equals more than $1.5 million per year.
Duke Power is working with Duke University on an ambitious cogeneration project.
