3. Outline • Why Develop a Plan • Existing Concerns • Potential Benefits • Penn State’s Strategy • Current Efforts • Anticipated Results

4. Sustainability Triangle At Penn State

5. Key Annual Statistics University Park Campus

6. Historical and Projected Energy Consumption Projected Consumption Un-mitigated Actual Consumption Major contributing factors are new square footage and plug load growth (ipods, computers, personal printers, file servers, cell chargers, etc.)

7. Rate capslifted Energy Production Cost Energy Consumption Projected Energy Cost Increases • Projected Annual Increases • 06/07 - $1.9 million • 07/08 - $2.0 million • 08/09 - $4.9 million • 09/10 - $5.7 million • 10/11 - $2.5 million • 11/12 - $2.5 million Price volatility and final impact of de-regulation.

8. Energy Use and Production • At current rate of consumption growth, University Park will exceed its firm steam capacity by 2009.

9. Penn State’s Plan • Initiate three simultaneous efforts: • Develop a long range Utility Master Plan with the following goals: • Satisfy capacity and reliability requirements • Develop steam system replacement strategy • Reduce exposure to fuel pricing volatility • Meet environmental compliance standards • Enhance environmental sustainability • Address aesthetic expectations • Provide a flexible and incremental long term strategy (recognize future uncertainty) • Work with a Tariff attorney to negotiate with the PUC • Develop internal energy conservation plan as part of university environmental strategy

10. Penn State’s Plan Utility Master Plan Findings • Electrical System - At current unmitigated growth rate, the campus electrical demand will exceed existing capacity by 2024. • Identified mitigation strategies for future consideration. • Chilled Water System - The campus chilled water system continues to expand faster than projected. • Established plan for system expansion based on projected failure points of stand alone systems • Incorporated expansion requirements into long term capital plan. • Determined that existing use of Electrically driven chillers is most cost effective approach.

11. Penn State’s Plan Utility Master Plan Findings • Steam System - Existing steam plant can be adequately maintained through 2020 with minor capital expenditures. • Current unmitigated growth rate will cause steam plant to exceed firm capacity by 2009. • Addition of Combustion Turbine Steam Generator for essential services will extend firm capacity to 2012. • Minor upgrade of distribution system will extend firm capacity to 2020. • There is no financial reason to replace plant today. • Recommended plant replacement is based on emerging technology which needs time to develop. • Aggressive energy conservation efforts can have a significant impact on extending the life of the existing systems.

12. Penn State’s Plan - Conversation • --Ensure all future growth is done in an environmentally responsible manner • Established Policy requiring all new and renewed facilities to be LEED (Leadership in Energy and Environmental Design) certified.

13. Recent Perspectives “ …While the results of Penn State’s efforts are unique to the University, other large building owners may wish to emulate Penn State’s process or adapt it to meet their needs.” -- Environmental Design & Construction, September 2007

14. Forest Resources BuildingLEED - Silver

15. Recent Perspectives “ …Penn State’s $30 million Medlar Field is the first LEED-certified stadium in the U.S. Green features include waterless urinals, gray water recycling, C&D waste recycling, and shared parking.” -- Building Design & Construction, September 2007

16. Borland Lab Renewal Restored Façade and Street View (Rendering) • Energy and Atmosphere • Add significant amounts of thermal insulation, underside of roof, certain exterior walls • Replacement windows with high performance clear glazing • Separate air handlers for east and west areas, for more efficient operation • Radiant heating panels at perimeter, above windows • High efficiency lighting at 1.1 watts / square foot Energy model predicts 21% energy savings

17. Penn State’s Plan -Conservation --Purchase Renewable Energy Credits

18. Penn State’s Plan Conservation -- Partner with research units on new technologies such as carbon sequestration, bio-digesters and solar collector design.

19. Penn State’s Plan - Conservation -- Continue with our initiative to reduce overall petroleum consumption by: • Continuing to reduce the impact of commuting by adding van pools, shuttles and other transportation efficiencies • PSU made the first ever list of “Best Work Places for Commuters for Colleges and Universities” • Converting some of our service vehicles to alternative fuels • Converting our diesel vehicles to use bio-diesel (B20) • Continually adding more flex fuel vehicles to our fleet

20. Penn State’s Plan - Conservation --Continue with our Guaranteed Energy Savings Program (GESP) and Energy Conservation Measures. • Payback: maximum of 10 years including financing cost • Annual volume: ~$10,000,000 • Typical Project Types • Lighting Retrofits • Steam Trap Upgrades • HVAC Controls Upgrades • Low Flow Plumbing Fixture Installation • Building Envelope Repairs • Re-Commissioning Existing Buildings

21. Penn State’s Plan - Conservation -- Continue with our building commissioning program • Commission New Buildings Penn State has developed a commissioning plan that is required for all new buildings on campus • Re-commission Existing Buildings Penn State has started an aggressive program to go back to existing buildings and re-commission the buildings to match their current use

22. Penn State’s Plan - Conservation -- Penn State has started an aggressive awareness campaign. We estimate that between 30 and 40 percent of our energy usage is under the direct control of the building occupants. There are important steps that can be taken in offices and residence halls to reduce dramatically our energy consumption.

23. What Each Person Can Do • Take Shorter Showers.Why: If every student who lives on campus at University Park reduced his or her shower by just five minutes, we would save 100,000 gallons of water each school year. That’s enough to fill five swimming pools! • Shut Down Your Computer at Night.Why: If all the resident students at Penn State Berks shut their computers down every night, it would prevent 692,251 pounds of GHGs per year • Keep Your Refrigerator Full. Why: Your refrigerator uses less energy when it’s full. Keep it stocked with fruit, bottled water, and your favorite snacks. • Use Compact Fluorescent Light bulbs.Why: An 18-watt compact fluorescent light bulb uses about 75% less energy than a 60-watt incandescent light bulb—and gives off about the same amount of light. (Fluorescent bulbs last longer, too.)

24. What Each Person Can Do • Don’t Let the Water Run When You’re Brushing Your Teeth.Why: You’ll save a gallon of water each time you brush. • Take the Stairs.Why: If every resident student at University Park took the stairs once a day instead of the elevator, it would prevent 7.2 million pounds of GHGs per year—the equivalent of taking 404 cars off the road. • Put Your Computer Monitor to Sleep. Why: Your computer monitor uses more energy than your hard drive. If you don’t want to shut down your entire computer, just put the monitor to sleep. Your IM programs will remain active. • Turn Off TVs and Other Electronics When Not in Use.Why: If 5,000 students turn off their TVs when not in use, it prevents 3.6 million pounds of GHGs per year—the same as taking 204 cars off the road.

25. What Each Person Can Do • Keep Windows Closed When the Heat Is On.Why:One pound of coal is burned for every hour your window is open during the heating season, creating fumes that cause air pollution. • Turn Off Your Screen Savers. Why: Screen savers don’t save energy. They actually use more energy than your computer does during normal operation. Many of them also prevent your computer from going into power-saving or “sleep” mode. • Turn Out the Lights When You Leave Your Room.Why: If the lights in every residence hall room at University Park were kept off for just one additional hour per day for one semester, it would be the same as taking 1,173 cars off the road. • Unplug iPod, Digital Camera, and Cell Phone Chargers When Not in Use. Why: Chargers consume a small amount of energy anytime they’re plugged in—even if they’re not charging. It might not seem like a lot, but at a school as big as Penn State, it really adds up.
