A brief description of when and why the building energy consumption baseline was adopted:
---
None
A brief description of any building temperature standards employed by the institution:
Temperature settings are centrally controlled by Facility Services. In 2009, we instituted a new energy-saving HVAC policy as well. During the academic year, academic buildings and public spaces like the Warch Campus Center will be maintained at a target temperature of 68 degrees (+/-2 degrees). In the summertime, academic buildings will be maintained at a target temperature of 76 degrees (+/-2 degrees).
None
A brief description of any light emitting diode (LED) lighting employed by the institution:
In 2011, we installed a full LED lighting system in a medium-sized parking lot as a pilot project. Pending assessment, we will continue to replace halogen and CFL lights with LEDs as budget allows.
None
A brief description of any occupancy and/or vacancy sensors employed by the institution:
Most classrooms, labs and many faculty offices are equipped with motion-detecting light sensors.
None
A brief description of any passive solar heating employed by the institution:
---
None
A brief description of any ground-source heat pumps employed by the institution:
---
None
A brief description of any cogeneration technologies employed by the institution:
---
None
A brief description of any building recommissioning or retrofit program employed by the institution:
---
None
A brief description of any energy metering and management systems employed by the institution:
Facility Services can remotely monitor energy usage in real-time, as well as track historical trends. In addition to monitoring use, we also have the ability to monitor real-time production from both of our solar PV arrays and our wind turbine.
None
A brief description of the institution's program to replace energy-consuming appliances, equipment and systems with high efficiency alternatives:
---
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:
---
None

Data source(s) and notes about the submission:
Our performance comparison year (2011) not only had an increased number of Heading Degree Days and Cooling Degree Days, but our campus added approximately 100,000 square feet of building space and 150 students in the intervening six years. The actual reduction, therefore, is even more pronounced than these data represent.
