A brief description of when and why the building energy consumption baseline was adopted:
In 2009 we began placing our electrical services lines underground. This moved the measuring meters for consumption from 16 buildings to one primary meter. To manage this energy and the resultant demand charges it became apparent that we needed to manage our HVAC and lighting systems more effectively. By putting our HVAC systems under control we have been able to not only manage our demand charges but, have been successful in reducing the energy required to climate control the affected buildings as well.
A brief description of any building temperature standards employed by the institution:
We use time of day scheduling to operate some buildings with occupied/unoccupied temperature settings. Timers are software logic to manage equipment settings.
A brief description of any light emitting diode (LED) lighting employed by the institution:
LED Lighting has been incorporated into new construction standards and installed at Baskin, Dickens, Horrell Hall, and McAfee. New garages have LED lighting installed, and LED retrofits are underway in many areas of campus. The primary sports arena was retrofitted for LED lighting. Several exterior fixtures have been retrofitted. The new Wedgewood Academic Center and Two Oaks residence hall are LED. In August 2015, the new Johnson Center Building was opened with all LED lighting. The Massey Center was renovated in 2015 and opened with new LED lighting as well.
A brief description of any occupancy and/or vacancy sensors employed by the institution:
Occupancy sensors are used in McWhorter Hall in offices/classrooms and Lab spaces. Exterior lighting is controlled by a combination of photocell devices or, astronomical clock managed through a series of control relays. Occupancy sensors have been installed at Curb Event Center, Baskin Law School, Dickens Residence Hall and McAfee Concert Hall, Wedgewood Academic Center and Two Oaks residence hall.
A brief description of any passive solar heating employed by the institution:
Classrooms and lobby spaces in the Wedgewood Academic Center are designed around the perimeter of the building in order to maximize passive solar lighting and heat.
A brief description of any ground-source heat pumps employed by the institution:
Geothermal water source heat pumps are in use in the Baskin Law Center and in the new Johnson Center building.
A brief description of any cogeneration technologies employed by the institution:
A brief description of any building recommissioning or retrofit program employed by the institution:
The Hitch Science building is currently being retrofitted with energy efficient VRF air conditioning and heating. The Massey Business Center was retrofitted with high efficiency boilers and LED lighting. The Maddox residence hall was retrofitted with a high efficiency chiller.
A brief description of any energy metering and management systems employed by the institution:
The Trane Tracer ES Energy Management system in nineteen (19) buildings is controlled by time of day scheduling. During unoccupied times the systems will expand the tolerances related to space settings. The system will poll all spaces and keep the building with tolerances established. The system uses outside temperatures and historical data to bring systems on-line before their occupied setting time is reached.
A brief description of the institution's program to replace energy-consuming appliances, equipment and systems with high efficiency alternatives:
A brief description of any energy-efficient landscape design initiatives employed by the institution:
The university is capturing underground water and redirecting it for irrigation. We are also designing green roofs into all new buildings We currently have green roofs on five buildings.
A brief description of any vending machine sensors, lightless machines, or LED-lit machines employed by the institution:
Vending machines have motion sensors and LED lighting.
A brief description of other energy conservation and efficiency initiatives employed by the institution:
Annual contest between Residence Halls for electric use reduction.
Installation of high efficiency boiler at Bunche Library.
Upgrade to high efficiency chiller at Maddox Residence Hall.
Retrofit of fresh air intake controls at Curb Event Center.
Installation of ice tank cooling system at McAffee Concert Hall.
Installation of chilled beam technology in the new Wedgewood Academic Center.
Jack Massey has been remodeled and two high efficiency condensing boilers have been installed.
