Figures needed to determine total building energy consumption:
Performance Year | Baseline Year | |
Grid-purchased electricity | 170,974 MMBtu | 116,938 MMBtu |
Electricity from on-site renewables | 2,992.56 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) | 158,910 MMBtu | 247,156 MMBtu |
Total | 332,876.56 MMBtu | 364,094 MMBtu |
Start and end dates of the performance year and baseline year (or 3-year periods):
Start Date | End Date | |
Performance Year | July 1, 2016 | June 30, 2017 |
Baseline Year | Jan. 1, 1990 | Dec. 31, 1990 |
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 building energy consumption baseline is 1990, this was adopted because this is the date that is being used for our Green House Gas Inventory, Climate Action Plan as well as various CSU system wide and state wide goals.
Gross floor area of building space:
Performance Year | Baseline Year | |
Gross floor area of building space | 6,196,426 Gross square feet | 2,601,699 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 | 0.14 MMBtu per square foot |
Source energy | 0.11 MMBtu per square foot | 0.24 MMBtu per square foot |
Percentage reduction in total building energy consumption (source energy) per unit of floor area from baseline:
52.24
Degree days, performance year (base 65 °F / 18 °C):
Degree days (see help icon above) | |
Heating degree days | 1,542 Degree-Days (°F) |
Cooling degree days | 2,101 Degree-Days (°F) |
Floor area of energy intensive space, 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):
---
A brief description of energy use standards and controls employed by the institution (e.g. building temperature standards, occupancy and vacancy sensors):
The campus uses E.O.987 for our building temperature standards of 68-78.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
The university is continuously upgrading lighting throughout the campus, both interior and exterior light fixtures to LED.
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):
CSUN has a 1 MW fuel cell generation operation that we recover waste heat from. This waste heat is then used for additional heating for our heating hot water (HHW) system as well as heating the University Student Union pool.
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):
