None
A brief description of when and why the building energy consumption baseline was adopted:
FY 2008 was the first compilation of GHG emissions as required by the signing of the ACUPCC.
None
A brief description of any building temperature standards 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.
None
A brief description of any light emitting diode (LED) lighting employed by the institution:
FOR THIS REPORTING CYCLE, SHAFER BELL TOWER, SCHEUMANN STADIUM WEST ELEVATION LIGHTS, ADMINISTRATION BUILDING BUSINESS AFFAIRS CONFERENCE ROOM all use LED lighting. ALL EMERGENCY EXIT SIGNS IN ALL BUILDINGS ON CAMPUS ARE ALSO “LED”.
None
A brief description of any occupancy and/or vacancy sensors employed by the institution:
ALL NEW AND RENOVATION PROJECTS INCLUDE THE INSTALLATION OF LIGHT SENSORS THAT ARE BOTH INFRARED AND MOTION DETECTING.
None
A brief description of any passive solar heating employed by the institution:
None
None
A brief description of any ground-source heat pumps employed by the institution:
47-building district-scale ground source heat pump installation nearing completion.
None
A brief description of any cogeneration technologies employed by the institution:
None
None
A brief description of any building recommissioning or retrofit program employed by the institution:
We are currently conducting a LEED Lab course sequence in cooperation with USGBC to recertify a LEED building under EBOM guidelines.
None
A brief description of any energy metering and management systems employed by the institution:
The University uses a building automation system that utilizes the Metasys system manufactured by Johnson Controls.
None
A brief description of the institution's program to replace energy-consuming appliances, equipment and systems with high efficiency alternatives:
We mandate energy star equipment for all replacements.
None
A brief description of any energy-efficient landscape design initiatives employed by the institution:
---
None
A brief description of any vending machine sensors, lightless machines, or LED-lit machines employed by the institution:
The university has installed an energy savings device on vending machines and requires all new vending machines meet EPA Energy Star criteria. The university has 100 bubble front soda vending machines that have a VMIq2 - Vend Misers device to reduce the number of compressor cycles during off-peak hours creating energy savings. Additionally, all glass-front beverage machines on campus have the highest EPA Energy Star ratings for conserving energy. All fifty-four snack vending machines use LED lighting that are energy efficient and use less power.
None
A brief description of other energy conservation and efficiency initiatives employed by the institution:
The geothermal system is used during the swing season to "trade" energy among buildings; thereby balancing heating and cooling loads.
None
