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 / GSF 0.14 MMBtu / GSF
Source energy 0.11 MMBtu / GSF 0.24 MMBtu / GSF

Percentage reduction in total building energy consumption (source energy) per unit of floor area from baseline:

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):
