Part 2. Reduction in source energy use per unit of floor area
Baseline year energy consumption
STARS 2.2 requires electricity data in kilowatt-hours (kWh). If a baseline has already been established in a previous version of STARS and the institution wishes to continue using it, the electricity data must be re-entered in kWh. To convert existing electricity figures from MMBtu to kWh, simply multiply by 293.07107 MMBtu/kWh.
| kWh | MMBtu | |
| Imported electricity | 51,731,147 Kilowatt-hours | 176,506.67 MMBtu |
| Electricity from on-site, non-combustion facilities/devices (e.g., renewable energy systems) | 526,649 Kilowatt-hours | 1,796.93 MMBtu |
Stationary fuels and thermal energy, baseline year (report MMBtu):
| MMBtu | |
| Stationary fuels used on-site to generate electricity and/or thermal energy | 122,804 MMBtu |
| Imported steam, hot water, and/or chilled water | 0 MMBtu |

A brief description of when and why the energy consumption baseline was adopted:
The baseline year was adopted to be consistent with our previous STARS reports.
Source energy
Total energy consumption per unit of floor area:
| Site energy | Source energy | |
| Performance year | 0.04 MMBtu per square foot | 0.09 MMBtu per square foot |
| Baseline year | 0.05 MMBtu per square foot | 0.11 MMBtu per square foot |

Optional Fields
A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
Energy efficiency is an integral part of CSULB's Climate Action and Adaptation Plan and is communicated to the campus community through the practice and implementation of energy efficiency and sustainability projects.
A brief description of energy use standards and controls employed by the institution:
The university's design and construction standards require all new buildings to have zero net energy and benchmark against a LEED Silver rating as a minimum. This standard is also consistent with the California Building Code requirements. The University has adopted a policy guiding building temperature standards which mandates 68 degrees for heating and 78 degrees for cooling. Occupancy/vacancy sensors are required in all new building construction and renovation projects as part of our mandatory building standards.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
The university is actively retrofitting lights to LED technology. Currently, 85% of all exterior lights and 45% of all interior lights have been retrofitted to LED lights.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:

A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
For the past few years, the university has been engaged in implementing an energy program aimed at retro-commissioning at least 300,000 square feet of building floor space on an annual basis. The goals of the program are to identify and correct mechanical system deficiencies, complete low-cost energy efficiency measures, and reduce building energy consumption by at least 15 percent in buildings that complete the program. To date, the university has completed retro-commissioning testing and pre-functional test repairs for the following buildings: FCS, PSY, SSPA, ET, COB, AS, HSCI, LA2, LA3, and LA4 (689,000 GSF of floor space)
