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):

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

Occupied Space -- Summer 74-76 degrees F; Winter 69-71 F
Unoccupied Space -- Summer 85 degrees F; Winter 55 degrees F

We incorporate both vacancy and occupancy sensors in our buildings. An occupancy sensor turn lights ON automatically upon the detection of motion then turns the lights OFF automatically soon after an area is vacated. Occupancy sensors may offer an option selection to switch the occupancy sensor from automatically turning the lighting on to A vacancy sensor requires manual activation of the lighting by the occupant then turns the lights OFF automatically soon after an area is vacated.
A vacancy sensor does not offer an option of automatically turning lighting on requiring a manual button press from the occupant (manual/vacancy mode).


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

We have done some recent lighting improvements projects to the campus, although small, but well needed. We have installed all new LED lights in all the hallways at Optics (1st, 2nd, 3rd, & 4th). Upgraded all the lights in our Central Plant Building to LED. Upgraded a lot of the exterior lights around MSB to LEDs. We have also upgraded all the lighting in Chan Auditorium and McDonald Douglas Center to LEDs.


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

We are constantly looking at upgrading old fluorescent lights to LED, older boilers to new higher efficiency non-condensing boilers (when funding is available), & installing higher efficiency AC units. In addition to this, we have a Building Automation System that is smart enough to calculate the cooling/heating need of the building so it optimizes run time. For example, instead of starting a building 2 hours early every day, the building automation system calculates how long it takes the building to reach comfort levels and makes the necessary adjustments. If it sees it reaches the comfort level in one hour then the next day the system will start one hour early. Unfortunately, at this time, we don’t do any re-commissioning of buildings. Did you want to mention hydration stations?


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

We do have three heat machines on campus that are super-efficient. Please see this article for details. https://www.achrnews.com/articles/137379-high-performance-projects-provide-comfort-sustainability-and-roi


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):
