A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:

The Ball State Energy Action Team (BEAT) oversees the Residence Hall Energy Challenge. The Challenge consists of the students living in the residence halls on Ball State’s campus, reducing energy consumption through changing simple tasks in their daily routine.

The winner is determined by how much the overall complex decreases their energy usage. The measurement is based on the electricity and energy consumption. Each
hall ‘s kilowatts are measured weekly with hopes of reducing their consumption by 10% of their starting baseline.

The winning residence hall receives a trophy (roving) and a pizza party at the end of the competition.


A brief description of energy use standards and controls employed by the institution:

WE DO NOT USE SET BACK CONTROLLERS. THEY ARE NOT ENERGY SAVERS FOR AN OVER-THE-NIGHT PERIOD OF TIME. WE USE VARIABLE VOLUME HVAC SYSTEMS WITH CO2 MONITORS. THIS TYPE OF ARRANGEMEMENT RAMPS THE INCOMING AIR SYSTEM DOWNWARD WHEN BUILDINGS ARE UNOCCUPIED. THE CO2 SENSORS ARE SET AT 800 PPM. WHEN THE 800 PPM CO2 LEVEL IS REACHED THE OUTDOOR AIR DAMPERS OPEN TO BRING IN MORE OUTSIDE AIR.


A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:

FOR THIS REPORTING CYCLE, SHAFER BELL TOWER, SCHEUMANN STADIUM FIELD LIGHTS AND WEST ELEVATION LIGHTS, ADMINISTRATION BUILDING BUSINESS AFFAIRS CONFERENCE ROOM, FACILITIES BUILDING, JOHNSON EAST, JOHNSON WEST, ELLIOT WAGONER DINING, WOODWORTH DINING, NOYER DINING, LaFOLLETTE DINING, WORTHEN ARENA AND CONCOURSE ALL use LED lighting. The football stadium is lit using LEDs. We have begun to convert all high pressure sodium street lights to LEDs. LEDs are now required in our facilities standards. ALL EMERGENCY EXIT SIGNS IN ALL BUILDINGS ON CAMPUS ARE ALSO “LED”.


A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:

Ball State University has completed installation of a District-Scale Geothermal (Closed-Loop, Ground-Source) Heat Pump Chiller Heating and Cooling System, which provides heating and cooling to 47 campus buildings (some 7.2 million square feet).

Related strategies include:

Weatherization of envelopes: The university routinely upgrades insulation levels in roof decks when replacing worn-out roof surfaces with new systems; specifically rock-ballasted built-up roofing is replaced with cool-roof EPDM continuous membranes and/or green roofs. In addition, window replacement with high performance glazing and thermal-brake framing has been adopted as an operational standard.

Behavioral change campaign/communications. The university has facilitated month-long energy conservation competitions within the nine residence hall complexes and among all academic buildings. These competitions occur in the fall and spring semesters and are promoted with campus-wide email exchange and web-based reporting of week-to-week performance.

Lighting retrofits. The university has aggressively switched-out T12, halogen, incandescent, and high pressure sodium lamps as part of its on-going maintenance and rehabilitation programs. In addition, for new construction and substantial facility renovation, specifications mandate the use of LED light fixtures, and occupy sensing lighting controls.

Boiler retrofit/central heating/cooling upgrades. This comprises the core activity by which the university is dialing-down its greenhouse gas emissions; having eliminated four coal-fired boilers, three centrifugal heat-pump-chillers, and five water-based cooling towers.

Building system retro-commissioning and upgrades including automation. The university routinely switches-out dated equipment; installing variable-speed pumps and fan motors, CO2 return-air sensors, sub-zoning of air-handling equipment where feasible, and use of digital sensors to control systems operation.

LEED Certification/LEED Buildings. In its the 2007-12 and 2012-17 Strategic Plans, the university had adopted LEED Silver as the standard for all new construction and renovations/upgrades. In some instances, the university has achieved LEED Gold ratings for some of its newer buildings.

Innovative Strategies. The university has engaged in long-range planning for the future use of alternative energy sources on campus and on outlying properties owned by Ball State; including building-integrated photovoltaics, stand-alone-armature photovoltaics and wind energy conversion. In addition the university has expanded the involvement of students in immersive learning opportunities on campus (e.g. LEED Lab) wherein students under the mentorship of faculty evaluate building energy performance and provide actionable reports.


A brief description of co-generation employed by the institution:

None


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

We are currently conducting a LEED Lab course sequence in cooperation with USGBC to recertify a LEED building under EBOM guidelines. We have been successful in obtaining a LEED operation and maintenance certification for an existing LEED building. We have a second building submitted now to USGBC and are working on our third.
