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

This was the first year that data was collected in a comprehensive manner.


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

The energy management system at the campus heating/cooling plant directs temperature regulation from the distribution point. Heating/cooling set points are based on occupancy hours.


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

LED lighting is being used in track lighting and display cabinets in the University Union, Kress Events Center, Laboratory Sciences, Instructional Services, and Weidner Center for the Performing Arts. LED lighting has also been installed in some exterior path lighting as well as in the University Union's Cloud Commons dining facility.


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

UW - Green Bay uses motion sensors to help reduce lighting related energy loads. Motion senors are in classrooms, labs, bathrooms and other spaces in 13 academic buildings on campus.


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:
---

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

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

We have a campus-wide energy management system that controls the chillers and boilers. We do not currently track energy performance for heating and cooling, but we do have electric meters in each building. The electric meters have to be read within each building. We are able to track btu usage in our condensate and chilled water. Approval for additional metering is currently being sought (2014) from the State of Wisconsin's Department of Administration and the UW System.


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 majority of our vending machines in the University Union are set up to turn their lights off after a period of inactivity and then will turn on when the first button is pushed. In addition, the refrigerated untis are set up with set-back timers so that during the overnight they allow the cooling temperatures to rise (to a certain threshold) and then start lowering to the desired temperature in preparation for the business day.
