None
A brief description of when and why the building 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.

None
A brief description of any building temperature standards employed by the institution:
The campus uses E.O.987 for our building temperature standards of 68-78.

None
A brief description of any light emitting diode (LED) lighting employed by the institution:
The university is continuously upgrading lighting throughout the campus, both interior and exterior light fixtures to LED.

None
A brief description of any occupancy and/or vacancy sensors employed by the institution:
The university has employed lighting controls, primarily occupancy sensors, in several buildings on campus as well as our parking structures.

None
A brief description of any passive solar heating employed by the institution:
---

None
A brief description of any ground-source heat pumps employed by the institution:
---

None
A brief description of any cogeneration technologies 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.

None
A brief description of any building recommissioning or retrofit program employed by the institution:
---

None
A brief description of any energy metering and management systems employed by the institution:
The University has a goal to meter all campus buildings for energy, water and natural gas. This project was started in FY 14/15 and by the end of 15/16 we will have metered 20+ buildings for electricity consumption. The majority of the campus is managed through our Siemens Energy Management System maintained by our Physical Plant Management department.
