Baseline Year June 1, 2015 May 31, 2016

A brief description of when and why the building energy consumption baseline was adopted (e.g. in sustainability plans and policies or in the context of other reporting obligations):

This was the most recent data available.

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency (e.g. outreach and education efforts):

We submit campus-wide internal communication (via the Connection) around Halloween to educate employees about phantom or vampire loads in attempt to make end users aware of their devices that are consuming energy when not in use. We also send out notices to remind people to close windows when we turn the air conditioning on in the spring.


A brief description of energy use standards and controls employed by the institution (e.g. building temperature standards, occupancy and vacancy sensors):

We maintain buildings at 72 degrees in the summer time (+/-2 degrees) and 70 degrees in the winter time (+/-2 degrees).


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

We have been retrofitting existing lighting to LEDs all over campus (all new lighting replacements are LEDs) and we are adding occupancy and vacancy sensors wherever we can.


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

A brief description of co-generation employed by the institution, e.g. combined heat and power (CHP):
---

A brief description of the institution's initiatives to replace energy-consuming appliances, equipment and systems with high efficiency alternatives (e.g. building re-commissioning or retrofit programs):
