Part 1
This credit is based on energy inputs from offsite sources and electricity produced by onsite renewables. When the institution purchases one fuel and uses it to produce heat and/or power, you should enter only what is purchased. For example, if the institution purchases natural gas to fuel a CHP system and produce steam and electricity, only the purchased natural gas should be reported.
| Performance Year | Baseline Year | |
| Grid-purchased electricity | 132,732.53 MMBtu | 137,318.90 MMBtu |
| Electricity from on-site renewables | 0 MMBtu | 0 MMBtu |
| District steam/hot water (sourced from offsite) | 0 MMBtu | 0 MMBtu |
| Energy from all other sources (e.g., natural gas, fuel oil, propane/LPG, district chilled water, coal/coke, biomass) | 55,718.60 MMBtu | 73,389.10 MMBtu |
| Total | 188,451.13 MMBtu | 210,708 MMBtu |
Start and end dates of the performance year and baseline year (or 3-year periods):
| Start Date | End Date | |
| Performance Year | July 1, 2017 | June 30, 2018 |
| Baseline Year | July 1, 2013 | June 30, 2014 |
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 for all STARS reporting (except Water Use) is FY 2013-14.

Optional Fields

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):
Cal State LA participates in LADWP's Demand Response Program throughout summer months. During periods of peak electricity demand, Facilities Services reduces the University’s energy load to relieve stress on the electrical grid, and an email is sent out to the campus community to support this sustainability effort by turning off lights in unoccupied rooms, working by daylight or “task” lighting, and unplugging any seldom used appliances.
A brief description of energy use standards and controls employed by the institution (e.g. building temperature standards, occupancy and vacancy sensors):
Cal State LA will henceforth not heat buildings above 70°F or cool below 76°F. Occupancy sensors are located throughout approximately 90% of all classrooms.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
LED lighting has been employed in Parking Structures, Welcome Center, Salazar Hall, Simpson Tower, BioScience, JFK Library, Phys Ed, Golden Eagle, King Hall, Golden Eagle and the Wallis-Annenberg Science Complex. Occupancy sensors are located throughout approximately 90% of all other classrooms throughout campus.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
The nine original campus buildings demonstrate passive solar buildings principles that retain solar heat in the winter and reject solar heat in the summer, including window overhangs and cool roofs. Window overhangs on south-facing windows allow winter sun in, while keeping summer sun from overheating buildings. A cool roof is one that has been designed to reflect more sunlight and absorb less heat than a standard roof.
A brief description of co-generation employed by the institution, e.g. combined heat and power (CHP):
None
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):
Cal State LA recently completed retro-commissioning projects at Salazar Hall, including major lighting, mechanical equipment and automation system programming upgrades. Lighting was upgraded to LED, zone boxes upgraded from constant-volume dual duct boxes to dual-damper variable air volume boxes, and the building automation system program updated to use DDC zone feedback to optimize air handler operation.
Salazar Hall annual energy savings: 629,722 kWh/yr and 75,743 therms/yr
Salazar Hall annual GHG emissions reductions: 775.27 metric tons CO2e/yr
Salazar Hall annual cost savings: $160,742/yr
Cal State recently completed a similar MBCx program at E&T, with plans for similar projectsat Simpson Tower and Fine Arts.
E&T annual energy savings: 779,525 kWh/yr and 33,440 therms/yr
E&T annual GHG emissions reductions: 583.15 metric tons CO2e/yr
E&T annual cost savings of $133,575/yr
