A brief description of when and why the building energy consumption baseline was adopted:
Required if end date of the baseline year is prior to 2005.
A brief description of any building temperature standards employed by the institution:
Standard temperature set points for offices and classrooms are 76 degrees for cooling and 70 degrees for heating with adjustment band of +/- 2 degrees.
A brief description of any light emitting diode (LED) lighting employed by the institution:
Approximately 250 LED lights were installed in Jesse Hall's Auditorium and almost all of the internal areas of the recently completed Gwynn Hall Renovation used LED lighting technology. LED lights have also been installed in the dressing rooms in the Fine Arts Building. Outdoor lighting in several areas across campus have also been upgraded using LED technology.
A brief description of any occupancy and/or vacancy sensors employed by the institution:
The majority of building lighting systems use motion sensors to shut off lights and set back temperatures when no motion is detected. Several buildings use light sensors to shut off lights if daylight can be used to light the space. (Daylight Harvesting)
Energy Conservation Program
• Lighting – In 1990 most lighting on campus was either incandescent or low efficiency fluorescent with magnetic ballasts. Today over 99% of the exterior lighting and over 90% of the interior lighting on campus has been converted to high efficiency lighting. Incandescent exit signs have been replaced with LED, reducing energy consumption by 80 – 90%. Daylight harvesting has also been used to automatically turn off interior lights in areas that receive sunlight.
• Motion Sensors – Motion sensors have been installed in thousands of classrooms, offices, conference rooms, and laboratories to turn off lights and set-back thermostats when spaces are unoccupied.
A brief description of any passive solar heating employed by the institution:
A brief description of any ground-source heat pumps employed by the institution:
A brief description of any cogeneration technologies employed by the institution:
The MU power plant uses a combination of 4 cogenerating steam turbines and 2 combustion turbines with heat recovery to simultaneously generate electricity and steam that is used for heating and cooling.
A brief description of any building recommissioning or retrofit program employed by the institution:
Animal rooms are recertified every three years by measuring air flows and checking room pressure differentials. HVAC controls are adjusted and recalibrated on several buildings a year to ensure ongoing energy savings and occupant comfort as part of an informal recommissioning effort.
A brief description of any energy metering and management systems employed by the institution:
Energy consumption for all campus buildings is metered at each facility. To enhance energy use monitoring; all chilled water meters, and nearly all electric meters are now remotely read. Steam meters are also being upgraded with this technology. Each month energy use data is entered into an automated billing and reporting management system and reviewed by Energy Management staff.
A computerized Building Automation System (BAS) allows remote monitoring and control of building infrastructure. A controls group is responsible for designing, installing, and maintaining building automation systems throughout the campus. These systems allow us to control heating, ventilating, and air-conditioning (HVAC) systems, lighting systems and mechanical equipment in classrooms, offices, residence halls, cafeterias, auditoriums, research facilities, gymnasiums and many other buildings. Currently we monitor and control over 120,000 control points in over 130 buildings consisting of over 9 million square feet. The process control network allows constant monitoring, system adjustments, programming, troubleshooting, and trending.
A brief description of the institution's program 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:
A brief description of other energy conservation and efficiency initiatives employed by the institution:
Energy efficiency design standards for HVAC systems are implemented on all campus projects to meet or exceed federal and state guidelines including:
Building envelope insulation, walls, roof, and thermal efficient windows
Energy Management Control Systems
Variable volume air and water circulation systems
Heat recovery on 100% outside air systems
Occupancy sensors for lighting control and temperature setback
High efficiency motors
High efficiency lighting systems
All buildings are fully metered for energy consumption. Metering data is analyzed and energy consumption patterns are identified. Buildings showing potential energy saving opportunities are audited and energy conservation projects are implemented.
Window film has been installed on several buildings to reduce radiant heating during the summer months.
During the winter months we take advantage of cold outside air to produce chilled water from “free cooling” heat exchangers to cool research equipment that needs cooling. Prior to installing this free cooling system, electric chillers were run year-round to provide for this need.
We continue with our program to convert fume hood systems to variable air volume.
Presentations and advertisements are used to encourage MU faculty, staff, and students to conserve energy. In addition, engineers in the Campus Facilities - Energy Management Department assist professors with tours and presentations for academic classes. Campus Facilities also educates the public on our energy conservation success.
