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 Central Energy Management & Controls System (CECMS) is programmed with building operating schedules that control the HVAC systems. The Air Handling Units turn on in the morning and off in the evening as commanded by these schedules. Individual thermostats are not common as they do not fit in with the energy management practice of centralized HVAC control which is tasked to operators at the campus Central Plant.
Building temperature standards are regulated by CSU Executive Order 987 and the CSU Sustainability Policy.

A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
In Washington Square Hall room 109, a large lecture hall, LEDs were used to replace the old HPS overhead pendant lamps.
All campus exterior lighting were converted to LED lighting.
MLK Library has undergone an LED lighting retrofit.
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:
At SJSU's Central Plant, the university owns and operates a highly efficient Cheng Cycle Cogeneration unit with a capacity of 6 MW. This consists of a natural gas fired turbine and a Heat Recovery Steam Generator (HRSG). On an annual basis, Cogen provides about 80% of the electricity for campus and nearly 100% of the steam load for building space heating and domestic hot water.
A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
Continuous monitoring based commissioning has been used for several of our buildings with the plan to eventually do all of our buildings and keep the buildings on a 5 year schedule.
Equipment purchased must Energy Star rated and IT equipment must be EPEAT
