Figures needed to determine total building energy consumption:
| Performance Year | Baseline Year | |
| Grid-purchased electricity | 176,514 MMBtu | 185,288 MMBtu |
| Electricity from on-site renewables | 1,797 MMBtu | 1,739 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) | 122,804 MMBtu | 114,315 MMBtu |
| Total | 301,115 MMBtu | 301,342 MMBtu |
Start and end dates of the performance year and baseline year (or 3-year periods):
| Start Date | End Date | |
| Performance Year | July 1, 2015 | June 30, 2016 |
| Baseline Year | July 1, 2009 | June 30, 2010 |
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):
The baseline year was adopted in order to be consistent with our greenhouse gas emissions inventory baseline of 2009-2010.
Gross floor area of building space:
| Performance Year | Baseline Year | |
| Gross floor area of building space | 5,527,017 Gross square feet | 5,522,402 Gross square feet |
Source-site ratio for grid-purchased electricity:
3.14
Total building energy consumption per unit of floor area:
| Performance Year | Baseline Year | |
| Site energy | 0.05 MMBtu per square foot | 0.05 MMBtu per square foot |
| Source energy | 0.12 MMBtu per square foot | 0.13 MMBtu per square foot |
Percentage reduction in total building energy consumption (source energy) per unit of floor area from baseline:
2.80
Degree days, performance year (base 65 °F / 18 °C):
| Degree days (see help icon above) | |
| Heating degree days | 1,218 Degree-Days (°F) |
| Cooling degree days | 1,752 Degree-Days (°F) |
Floor area of energy intensive space, performance year:
| Floor Area | |
| Laboratory space | 305,026 Square feet |
| Healthcare space | 38,629 Square feet |
| Other energy intensive space |
EUI-adjusted floor area, performance year:

Documentation (e.g. spreadsheet or utility records) to support the performance year energy consumption figures reported above:
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 efficiency is an integral part of CSULB's Climate Action Plan and is communicated to the campus community through practice and implementation of energy efficiency and sustainability projects.
A brief description of energy use standards and controls employed by the institution (e.g. building temperature standards, occupancy and vacancy sensors):
The university has adopted a policy guiding building temperature standards which mandate 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. CSULB has been installing sensors in building spaces for many years.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
The University began converting campus lighting fixtures to LED in 2008 and continues to transition to LED lighting throughout campus.
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):
The University's Procurement Office recommends that, when departments need to replace equipment that has reached the end of its useful life, they choose equipment with an EnergyStar or equivalent rating for energy efficiency.
