A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
UNCW works with the UNC System yearly at the Appalachian State Energy Summit to create a culture of energy efficiency throughout the state. Each light switch has a "conserve energy, turn off the lights" sticker and each fume hood is also getting a energy-savings sticker. Other programs such as Gold Talon events reinforce these ideas with education, information, and recognition, as well as our Gold Talon Office recognition program that promotes the use of practices, such as turning off lights and using more natural light to encourage energy efficiency.
A brief description of energy use standards and controls employed by the institution:
UNCW abides by Section 302 of the North Carolina Energy Conservation Code, which addresses interior design conditions. The policy requires temperatures used for load calculation to be a maximum of 72 degrees Fahrenheit for heating and a minimum of 75 degrees for cooling. Additionally, buildings are reset when unoccupied to a minimum of 77 degrees for cooling and a maximum of 60 degrees for heating.
UNCW also observes summer hours. From mid-May to mid-August, the entire campus works an alternate schedule that allows them to have a half-day on Fridays, with the campus essentially shutting down at 11:30 am. All buildings shift to unoccupied, and HVAC temperatures are adjusted for zero occupancy, allowing the campus to reap significant energy efficiencies across all buildings the entire summer.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
LEDs were installed in facilities that were part of an Energy Services Performance Contract (ESPC). These two contracts were recently implemented and involved upgrades to 27 campus facilities. Also, the expansion of the Student Recreation Center saw upgrading to LED lights in places like the basketball court's scoreboards. All outdoor lighting fixtures on Chancellor's Walk, Wagoner Dining Hall, and Trask Coliseum have been replaced with LED bulbs.
Funding for these retrofit projects is established with the state's 1292 fund, which allows for investment and payback for any energy use reduction retrofits. These monies roll year over year.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
The HUB is a Dining Facility that was built to utilize passive solar. Also, solar panels are used to ensure the Student Recreation Center's pool remains at a minimum temperature.
A brief description of co-generation employed by the institution:
UNCW does not have any cogeneration technologies installed on campus
A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
Recent ESPCs have involved the replacement of large energy-intensive equipment, such as boilers and air handling units, with more efficient upgrades. The university also keeps a priority list of campus equipment that needs upgrading. After Hurricane Florence, Dobo Hall went through extensive renovations that included improving the energy efficiency of its A/C units, as well as other high-energy intensity systems. The HVAC systems in one of the larger residence halls, Seahawk Crossing, were replaced with more efficient units last summer.
