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

Cornell's outreach and education efforts are numerous,
Outreach/engagement efforts include:
Building energy dashboard
Student sustainability leaders
Green Ambassador program
Green Certification Program for Offices/Labs and Events
Sustainability Clubs
Energy smackdown competition
Education efforts include the following:
Atkinson Center for a Sustainable Future
Center for Sustainable Global Enterprise
Cornell Institute for Climate Smart Solutions
Cornell Cooperative Extension
Cornell Energy Institute


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

All digitally controlled buildings are scheduled to relax temperatures during unoccupied periods to reduce energy use.


A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:

Beginning in FY16, a campus wide LED re-lamp program was initiated. The program was completed in FY17. The program reduced electric consumption by approximately 9 million kwh. Prior LED lighting upgrade projects include (1) high bay lighting in many of Cornell's Athletics facilities.

A brief description of co-generation employed by the institution:

The Cornell Central Energy Plant (CEP) is a combined heat and power plant. Cornell placed into service two Solar Titan 130 Combustion Turbines (2@15 MWe)with Rentech dual pressure Heat Recovery Steam Generators in December of 2009. In addition, there are two back pressure steam turbines (8 MWe total) that produce electricity with steam prior to the steam being used for heating purposes on campus. The CEP has allowed the university to discontinue the use of coal (2011). Energy generated with co-generation technology includes electric and steam.


A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:

All buildings central mechanical systems are re-commissioned on a 24-36 month cycle.
