Total 823,497.60 MMBtu 754,722.90 MMBtu

Start and end dates of the performance year and baseline year (or 3-year periods):
Start Date End Date
Performance Year Sept. 1, 2016 Aug. 31, 2017
Baseline Year Sept. 1, 2011 Aug. 31, 2012

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):

"Baseline year selected based on the context of the State Energy Conservation
Office (SECO) mandated SB 898 report"

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):

Energy Conservation Committee (ECC) consists of student(s) and staff that work together to disseminate useful energy conservation techniques to the San Marcos community members. Currently, the ECC is working with University Seminar (freshman requisite course) to create talking points addressing this that can be inserted in the course's existing syllabi.


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

Automatic light sensors on new buildings, buildings minimum and maximum temperatures set to energy efficient temperatures.


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

All new and future buildings are fitted with LED lighting and all parking garages and
some classrooms were retrofitted with LEDs.  Use LEDs when replacing lighting all around campus.


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

0


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

0


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):

Two building were retrofitted and data indicates that they are now more efficient.
