Part 2. Reduction in source energy use per unit of floor area
Baseline year energy consumption
STARS 2.2 requires electricity data in kilowatt-hours (kWh). If a baseline has already been established in a previous version of STARS and the institution wishes to continue using it, the electricity data must be re-entered in kWh. To convert existing electricity figures from MMBtu to kWh, simply multiply by 293.07107 MMBtu/kWh.
| kWh | MMBtu | |
| Imported electricity | 219,309,140 Kilowatt-hours | 748,282.79 MMBtu |
| Electricity from on-site, non-combustion facilities/devices (e.g., renewable energy systems) | 4,627,180 Kilowatt-hours | 15,787.94 MMBtu |
Stationary fuels and thermal energy, baseline year (report MMBtu):
| MMBtu | |
| Stationary fuels used on-site to generate electricity and/or thermal energy | 2,044,800 MMBtu |
| Imported steam, hot water, and/or chilled water | 0 MMBtu |

Optional Fields
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. For more information about specific projects and locations:

A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
Earh Source Heat (ESH) is Cornell's deep direct use enhanced geothermal initiative exploring use of the technology to supply heat to the campus district system. Cornell's first GSHP system is under construction in 2024 for a building that is not connected to the district energy systems.

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.
