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 | 48,195,831 Kilowatt-hours | 164,444.18 MMBtu |
Electricity from on-site, non-combustion facilities/devices (e.g., renewable energy systems) | 0 Kilowatt-hours | 0 MMBtu |

Optional Fields
A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
The Campus Sustainability Office and/or Student Sustainablity Center tables at orientations and other events throughout the year on campus, providing students, staff, and faculty with information about how to help us reach our sustainability goals
The Campus Sustainability Office provides training for all Resident Advisors so they have information and tips to share with their residents on how to conserve energy while living in residential facilities.
The Student Sustainability Center's EcoReps program provides peer-to-peer educational programs for residents living in housing
The PSU Climate Champions Program is designed to promote and recognize resource conservation and stewardship within PSU departments, as well as to support the goals of our Climate Action Plan.
The Campus Sustainability Office presents to classes and at departmental meetings across campus providing education and resources to students, staff, and faculty.
IT has a computer shutdown policy implemented across campus to minimize unnecessary idle time. Across campus, PSU has installed light switch stickers to induce behavior change, and combined behavioral efforts with additional lighting controls and occupancy sensors to yield more efficient uses.
A brief description of energy use standards and controls employed by the institution:
-Conditioned spaces will be heated to a temperature range of 67-70 in the winter
and cooled, where applicable, to a temperature range of 72-76. Plan for the
season and dress appropriately.
-Personal or University owned space heaters will not be allowed, unless approval
from FPM has been granted for cases where spaces cannot otherwise be heated
to the appropriate range. Once approval has been granted, space heaters must
comply with fire code, be turned off when a space is not being occupied and be
selected with energy efficiency and safety as top priorities. FPM will then work to
identify a long range solution to heating the space to an appropriate level.
-Building ventilation will be based on actual use of the space, as determined by
Academic Schedules, Posted Building Occupancy, and Special Events.
-Windows in conditioned spaces are to remain closed when building conditioning
systems are operating.
-All supply and return air vents in offices, classrooms, and laboratories must be
unobstructed at all times.
-Utility Manager and Facilities staff will work with events scheduling team to
consolidate activities into energy efficient buildings on campus
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
-All spaces will be lit to an appropriate lighting level for the tasks being performed. Extra
effort will be made to ensure that unoccupied spaces are left at minimum acceptable
levels.
-Building occupants are encouraged to take advantage of natural light, whenever
possible.
-New construction and renovation will incorporate daylight sensing technology, allowing
overhead fixtures to dim when outside lighting is sufficient.
-Utilize energy efficient bulbs in task lighting (i.e. compact fluorescent or LED)
Parking Garages have been converted to LED lighting, Lighting Retrofit Project for converting Hoffman Hall to LED lighting was approved by the Green Revolving Fund in FY 14, as was an exterior LED lighting and daylight control project for Science Building 1. All street lighting along the park blocks running through campus are also LED. PSU is currently working on several other lighting upgrades that will include LEDs.
In 2017/2018 the Student Building Fee Committee approved funding to upgrades several classrooms across campus to LEDs. This year PSU is scoping a project to get the remaining general purpose classroom converted to LEDs using our Green Revolving Fund.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
-CH chillers use well water for condenser water
-A portion of our newly renovated Karl Miller Center includes passive design.
A brief description of co-generation employed by the institution:
PSU is also looking into adding heat recovery chillers to our district energy loop. We hope to fund this work through our Green Revolving Fund.
A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
Since inception, the GRF has supported over 15 projects and resulted in an anticipated energy savings of over $250,000 annually.
Example Projects:
-Millar Library and University Center Building retrocommissioning
-Science Research & Teaching Center stand alone chiller for energy intensive labs
-Science Research & Teaching Center installation of Zenn Valve to reduce water usage
-Millar Library LED upgrades
-Science Building One installiton of heat revoery chiller and electric hot water heater to reduce laod on campus loop boilers in the summer months
Other projects not included in the GRF: Fourth Avenue Chiller replacement and heat-recovery chiller, West Heating Plant new boilers, SRTC Heat Recovery for summer and winter operations, MCB natural gas boiler replaced electric resistance heat. CH domestic hot water now via Heat Recovery from Telecom room cooling system
