A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
SCU holds an annual Energy Challenge in which residence halls compete against one another to reduce their consumption of electricity over the course of a month. Winning residence halls receive special social events and prizes.
A brief description of energy use standards and controls employed by the institution:
Building thermostat set points are 74-78F for cooling and 69-72F for heating. At 11:00 PM, where building systems permit, thermostat set points are remotely adjusted to 60F for heating and 85F for cooling. Exceptions are made only for certain buildings with tighter temperature requirements. Buildings will return to their day operating mode by 7:00 AM daily.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
LED lighting systems are currently used in 15/64 (23.43%) of buildings and 6/64 (9.375%) buildings have partial LED lighting systems. SCU has installed motion and ambient light sensors in a number of buildings. Building temperatures are controlled by a central system to ensure no unnecessary heating/cooling.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
New buildings are designed to maximize natural day lighting and utilize passive solar heating through solar chimneys and building/flooring materials that absorb solar heat and release that heat slowly to warm the space.
A brief description of co-generation employed by the institution:
N/A
A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
SCU constantly replaces high-energy consuming fixtures and devices with energy-efficient upgrades.
