A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
Various programs target behavior change on a small scale. An updated list is covered in the Energy category of our blog: https://blogs.oregonstate.edu/ecologue/category/energy/
A brief description of energy use standards and controls employed by the institution:
Most OSU buildings have temperatures regulated by centralized building automation systems (BAS). The BASs adjust temperature depending on hours of occupancy for the specific building and, in some spaces, based on actual occupancy using interior sensors.
Buildings not on BAS systems also typically have some sort of timing for HVAC control.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
LED lamps are currently being used in hundreds of locations on campus, usually replacing incandescent lamps, and most recently, replacing some fluorescent as well. New construction has implemented LED lighting technology for interior and exterior application.
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 the LEED Platinum Energy Center, electricity is generated in a gas turbine (fueled by natural gas), which then creates high quality waste heat. This waste heat is used to make steam for campus. The Energy Center provides about 40% of the electricity for campus. https://fa.oregonstate.edu/sustainability/operations/green-building/completed-construction
