FitRec Boston University's Campus Fitness Center

Implementing energy-saving technologies is imperative in all buildings, from a small apartment to a large institution. As you can imagine, working with spaces of such magnitude as FitRec and the Agganis Arena can have a very large impact on the environment. Here are some key elements that have been incorporated into the buildings to reduce their carbon emissions:

CO2 Monitors

  • By monitoring CO2 levels, the building’s energy management system can determine how much fresh air is required. Since fresh air needs to be either heated or cooled, adjusting the amount of air delivered also controls how much energy will be used, which can considerably cut down on waste. In the past, fresh air levels were controlled with prescriptive measures, not real-time needs.

Monitors are located in the Agganis Arena air-handling systems, and in the FitRec center’s four-court and three-court gyms. In addition, localized sensors are connected to the central air handling unit that ventilates a number of smaller spaces, including exercise rooms, a dance studio, and a black-box theater in the Boston University Theatre on Huntington Avenue.

Occupancy Sensors

  • Occupancy sensors vary the flow of the locker room exhaust system.

Variable Speed Drive System

  • Variable speed drives have been installed for the chilled water and heated water coils that manage air temperature. On an 80-degree day, for example, a building equipped with a variable speed drive system can optimize horsepower by running chilled water pumps more slowly than would be needed on a 90- degree day.
  • Humidity control can be optimized with dual path air handling systems before mixing it with a building’s return air.

Lighting

The following lighting projects were completed this summer:

Arena

  • Re-lamped and re-ballasted in the back supporting areas such as offices, lockers, restrooms, and loading docks.

FitRec

  • Replaced all metal halide lamps, basketball courts, multipurpose courts, and pool with T5 high output fluorescent system equipped with electronic ballasts, acrylic lens and wire guard.
  • Re-lamped and reballasted all T8 to Super T8 lamps and efficient ballasts in the buildings.
  • Replaced all halogens with LEDs or CFLs.
  • Installed occupancy sensors in the basketball courts, multipurpose courts, lockers, stairways and mechanical rooms.

Garage

  • Replaced existing metal halide lamps with super T8 fluorescent, cold-temperature ballasts, and Vapor-Tight lens.
  • Motion sensors installed; 10 percent hardwired on for safety.
