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

This was the year before energy efficiency and carbon footprint reduction efforts began.


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

We have installed energy management systems in buildings which represent 89% of our total campus building space. These systems are used in conjunction with individual building occupancy schedules to automatically turn off the HVAC systems off during unoccupied periods and perform setback of the space temperatures to 60 degrees in the winter and 80 degrees in the summer.


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

We have installed LED lighting in a number of locations, including some parking structures, our competition hockey arena, trophy cases, etc.


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

We have installed lighting sensors in buildings which represent 34% of our total campus building space. Our focus has been in areas of intermittent use such as conference rooms and restrooms to turn off the lighting when sound and motion are not present. Our building design standards (page 51 of below URL) for both new and retrofit projects included the integration of lighting occupancy sensors into the project design and we continue to leverage this technology as part of our Energy Conservation Program which includes a Lighting Component.

Recently we were able to apply motion sensor in one of our Gymnasiums to sense occupancy on three basketball courts and turn the lights associated with any of the individual court off when not in use.


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 energy management systems in buildings which represent 89% of our total campus building space. The systems include Johnson Metasys, Tridium and Tracer Summit. Currently we are in the process of installing an Iconics Graphical User interface for the Johnson Metasys system in an effort to standardize our trending, scheduling and trending capabilities as well as enhance our ability to effectively monitor and identify HVAC related issues as they occur and to mediate before any significant impact to equipment efficiency. These systems monitor both steam and chilled water delivery to each building connected to our Central Plant and allow for occupancy scheduling of HVAC systems throughout the campus. We also use the energy management systems to augment our re-commissioning efforts.


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 joint project between facilities and the Sustainability Committee of Undergraduate Student Government installed Vending Miser sensors on vending machines across campus.


A brief description of other energy conservation and efficiency initiatives employed by the institution:
