A brief description of when and why the energy consumption baseline was adopted:

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.

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
---

A brief description of energy use standards and controls employed by the institution:

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:

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.

Data source(s) and notes about the submission:

The small difference between gross floor area of building space (performance year) and the gross floor area of building space reported in PRE-4 is because these numbers refer to different years. 2019 was selected as the performance because it was the most recent calendar year representative of normal operations (due to the COVID-19 pandemic). Figures in PRE-4 reflect the 2020 year, and include some additionally-constructed building space.
