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 | 331,238,258 Kilowatt-hours | 1,130,184.94 MMBtu |
| Electricity from on-site, non-combustion facilities/devices (e.g., renewable energy systems) | 0 Kilowatt-hours | 0 MMBtu |
Stationary fuels and thermal energy, baseline year (report MMBtu):
| MMBtu | |
| Stationary fuels used on-site to generate electricity and/or thermal energy | 2,275,949 MMBtu |

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
Through Penn State Sustainability, there are Sustainability Programs that focus on outreach and education for faculty, staff and students. Green Paws, an office certification program, incorporates energy efficiency and reduction actions in the 4-Level program. For students, the Eco-Rep program provides an opportunity for students to learn about energy efficiency and conservation and then share that information with peers through fun activities and events.
Office of Physical Plant staff teach and guest lecture in a variety of engineering, architecture and sustainability classes.

A brief description of energy use standards and controls employed by the institution:
Penn State has an Energy Conservation Policy (AD64). Set points are specifically addressed in the policy:
Interior Environment - Every effort will be made to maintain the occupied temperature in all University facilities at 70 degrees in the winter and 75 degrees in the summer. This excludes areas that currently are not heated or cooled and areas with special environmental needs.
-The temperature during low occupancy or unoccupied periods in all University facilities will be allowed to cool down to 60 degrees in the winter and warm up to 85 degrees in the summer. This excludes areas that currently are not heated or cooled and areas with special environmental needs.
-Employees and students with manual control of the equipment that heats or cools their space shall operate the equipment so that the least amount of energy is consumed (example, operate window air conditioning units only when the spaces are occupied).

A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
Light Emitting Diode (LED) technology is used for various applications in many buildings on campus. All new construction or renovation attempts to incorporate the technology. Common applications include replacing incandescent bulbs in elevators, down light applications exit signs and parking lots. They have even been installed in Penn State's -40 degree Blast Freeze in the Food Science Building. 3 Parking decks (Nittany, HUB, East) have LEDs for upper deck lighting, stairways and access lighting with multi-level occupancy sensor and daylight controls. LEDs have been used for underbowl lighting at Beaver Stadium as well as the new logo signs. LEDs have been used in complex lighting locations including the HUB Art Gallery, Earth & Mineral Science Museum, the Nittany Lion Shrine and the Pegula Ice Arena.

A brief description of co-generation employed by the institution:
Penn State operates two Combined Heat and Power Plants. In additional to 3 natural gas boilers, the West Campus Steam Plant has three backpressure steam turbines and a combustion turbine. In additional to two natural gas boilers, the East Campus Steam Plant has a combustion turbine and heat recovery steam boiler to cogenerate steam and electricity. Onsite electricity generation via cogeneration serves Penn State's emergency power needs.
A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
Continuous Commissioning (CCx) - Commissioning occurs shortly after a building’s completion to verify if it is functioning according to its design objectives. Implemented in 1998, the University Park Continuous Commissioning Program (CCx) focuses on the re-commissioning, retro-commissioning, and maintenance of campus buildings. The goals of the program are to reduce energy costs and optimize building performance. CCx are “corrective” projects that typically have a 5-year simple payback. The program currently includes 2 CCx Engineers and three 2-person technical service crews. These savings are repurposed toward other energy saving projects.

Data source(s) and notes about the submission:
In 2014, Penn State joined the U.S. Department of Energy’s Better Buildings Challenge and pledged to reduce its building portfolio’s energy use by 20 percent over the next decade. With a commitment of 28 million square feet (all campuses except Hershey Medical & Pennsylvania College of Technology), Penn State becomes the largest university in the program.
