Energy

• Green Lights Program to replace inefficient light fixtures; saved $10M over 10 years.
• Campuswide relamping program is underway to replace F32 fluorescent lamps with F28 lamps for energy reduction.
• Energy Recovery is now implemented into design where appropriate. Energy recovery includes, but is not limited to heat pipes and energy recovery units. Several buildings being retrofitted with heat pipe devices.
• Return duct is insulated even though not required by Florida Building Code – Energy.
• Low use water fixtures (1.6 gal/flush, minimum)
• Reduction of use of remote tertiary pumps at some buildings. This saves energy back at the plant for not over pumping and at the building in power consumption.
• All new buildings have night setback and/or occupied/unoccupied control. This is controlled by Environmental Controls. Lights are typically on motion sensors, as well as many older buildings have been retrofitted. Further sensors installations are under discussion.
• All campus facilities were modified under Green Lights program with energy efficient T8 lamps and electronic ballast type lighting fixtures, compact fluorescent, other efficient lamps, and motion sensors.
• Programmed replacement of old inefficient chillers with new efficient chillers
• Cost efficient purchasing of natural gas through gas transportation contracts has saved $7.7 million in gas costs.
• Heat recovery from boiler stacks
• Energy meters in each building for all utilities to allow for monitoring and energy accounting and measuring success of energy management measures
• On re-roofing projects increased roof insulation and installed a white cap with SRI of 93 for high reflectivity and energy efficiency
• Close buildings for usage outside of normal operating hours of offices and classes to reduce energy consumption. Also reduces after-hours cleaning.
• LED lighting for traffic lights
• Automatic sensor type faucets in several buildings
• Vendmiser motion sensing vending machines
• Replaced all steam absorption chillers with very efficient electric centrifugal chillers. Newer chillers use R-123 that provides one of the highest energy efficiency.
• Chilled water distribution system is being converted to variable primary pumping system to improve energy efficiency in distribution as well as generation of chilled water.
