A brief description of when and why the building energy consumption baseline was adopted:

Most recent allowable baseline and performance year.


A brief description of any building temperature standards employed by the institution:

UNCW follows Schedule D, Standards of Comfort and with the 2012 NC Energy Conservation Code, section 302 Design Conditions. Interior design conditions for cooling load calculations shall be a minimum of 75 degrees F for cooling and a maximum of 72 degrees F for heating. The same minimum and maximum temperature set points should be used for cooling and heating. A five degree deadband is required between heating and cooling. Buildings are reset when unoccupied to minimum of 77 degrees F for cooling and a maximum of 60 degrees F for heating


A brief description of any light emitting diode (LED) lighting employed by the institution:

UNCW has a performance contract in the works that will convert the majority of outdoor lighting to LED. UNCW has ongoing projects to replace indoor lighting with LED.


A brief description of any occupancy and/or vacancy sensors employed by the institution:

In some buildings, UNCW use occupancy sensors in buildings to turn off lights and also put the HVAC into a “standby” mode. This is standard design practice for all major renovations and new buldings


A brief description of any passive solar heating employed by the institution:

UNCW currently does not employ and passive solar heating on campus, with the exception of the greenhouse.


A brief description of any ground-source heat pumps employed by the institution:

UNCW currently does not have any geothermal heat pumps on campus.


A brief description of any cogeneration technologies employed by the institution:

UNCW does not have any cogeneration technologies installed on campus


A brief description of any building recommissioning or retrofit program employed by the institution:

UNCW is retro-commissioning 3 buildings on campus (Wagoner Dining Hall, Fisher Student Center, Fisher University Union) UNCW has instituted commissioning on all new construction projects and major renovations.


A brief description of any energy metering and management systems employed by the institution:

UNCW’s goal is to install metering on all buildings and to bring this metering information into the BMS. UNCW has currently purchased Utility Billing Software that will automate billing.


A brief description of the institution's program to replace energy-consuming appliances, equipment and systems with high efficiency alternatives:

UNCW has no set program in place 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:
---

A brief description of any vending machine sensors, lightless machines, or LED-lit machines employed by the institution:

UNCW has a performance contract in process that will install sensors on vending machines to reduce their energy consumption when there is no one around.


A brief description of other energy conservation and efficiency initiatives employed by the institution:

UNCW is in process of doing it’s second Energy Saving Performance Contract. This $10.2M project will be implemented in approximately 20 of UNCW’s buildings
