This policy applies to all occupants of facilities owned or operated by Liberty University and its subsidiaries.
Building Design Standards
The University’s buildings are designed to maintain a heating setpoint of 68°F and a cooling setpoint of 76°F for outdoor air conditions that occur 97% of the time during a typical meteorological year.
Occupied Building Temperature Setpoints
When a building is in use (occupied), the temperature controls will heat the building up to 68°F during heating season and cool the building to 74°F during cooling season. Temperatures in between 68°F and 76°F are considered within the acceptable comfort range across the University during the design outdoor air conditions.
The temperature controls only adjust to temperature changes at the temperature sensor location, so adjacent spaces without a sensor may be warmer or cooler. Where spaces are equipped with sensors that allow setpoint adjustment above and/or below the seasonal setpoints, the occupants of those spaces should be respectful in considering other building occupants before making temperature adjustments. Where spaces are equipped with sensors that allow setpoint adjustment, the heating setpoint may be set lower than indicated above, and the cooling setpoint may be set higher than indicated above.
Note that it is the responsibility of employees and students to dress appropriately for the weather conditions.
Unoccupied Building Temperature Setpoints
When a building is not in use (unoccupied), the temperature controls will not operate unless the temperature falls below 62°F (heating) or rises above 82°F (cooling).
Facilities Management coordinates with the Events Dept. and Facility Managers to determine the hours of operation for each facility. These hours of operation are the basis for the occupied/unoccupied schedule.
Certain spaces or venues may be designed to operate at temperatures outside the seasonal setpoints for special occupancy conditions.
Some examples are the Ice Center, Natatorium, Cadaver Labs and Server Rooms. These spaces/venues are an exception to this policy as they are engineered to operate at special setpoints.
University buildings are designed in accordance with the Virginia Uniform Statewide Building Code (VUSBC) which incorporates by reference the International Mechanical Code (IMC), the International Energy Conservation Code (IECC) and ASHRAE 90.1 (Energy Standards for Buildings).
To establish a uniform policy for building heating and cooling temperature setpoints aligned with the building code, industry accepted standards and energy efficient operation.
Definition of Glossary Terms
ASHRAE: American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE, pronounced ash-ray) was founded in 1894 and has more than 50,000 members worldwide. This non-profit industry standards organization focuses on building systems, energy efficiency, indoor air quality, refrigeration and sustainability technologies. ASHRAE publishes a set of standards and guidelines relating to HVAC systems and issues, that are often referenced in building codes and used by consulting engineers, mechanical contractors, architects, and government agencies.
HVAC: Heating, ventilating and air conditioning
Temperature sensor: A temperature measurement device, usually wall-mounted, which provides feedback to the temperature control system so it can modulate HVAC heating and cooling valves or relays in an effort to match the air temperature near the sensor to the sensor setpoint
