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

Guilford College signed with ACUPCC in 2007


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

Much of the college's building space is controlled and monitored by a building automation system. Temperature regulations are maintained at 74 degrees cooling and 68 degrees heating with an operator controlled delta of 2 degrees where capable thermostats are located. Buildings are only scheduled to operate when needed. During periods of vacancy the building automation system will trigger HVAC controls to follow unoccupied temperatures of 80 degrees cooling and 55 degrees heating.


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

The model green classroom in King Hall has LED overhead lighting. LED post lights were selected during a major plaza renovation and due to their success we have adopted that all post mount lights will be LED as budget and maintenance requirements allow. Currently, we are testing LED in exterior lighting applications such as wall packs, spot lights, etc.


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

The lighting retrofit project of 2010 added occupancy sensors to many of the large classrooms in King, Duke, and Frank Family Science Center. Also, occupancy sensors have been installed in any applicable space resulting in a financial payback of 2 years or less. Here Library has an extensive smart lighting strategy.


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

The college has over 200 solar thermal hot water panels installed at most residence halls for domestic hot water needs. Also, this technology provides much of the hot water for cafeteria cooking needs.


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

n/a


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

n/a


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

Building automation systems are being upgraded during major renovations. Our Maintenance Department has a dedicated building automations systems technician to verify air flows, temperatures, and other HVAC requirements.


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

All campus buildings have electric and natural gas meters where applicable. Our campus water is fed by two large meters and are monitored at a macro level. Campus steam is monitored at the natural gas used to create the steam, but no outgoing steam or condensate return is monitored at this time. All energy data is recorded and monitored monthly by utilizing our energy management software, Energy Cap.


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

During renovations, remodels, routine maintenance, etc. we select Energy Star appliances, per our Energy Star Purchasing requirement.


A brief description of any energy-efficient landscape design initiatives employed by the institution:

Native plants are selected for landscape renovations and seasonal planting to minimize negative impacts associated with disease, watering requirements, etc . Grasses are selected for specific applications (shade vs. full sun) to minimize required watering.


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

Instead of installing motions sensors, all of our beverage vending machines have had their lights disabled. This initiative saves more energy than sensors would.


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

ASHRAE Level II Energy Auditing
