Energy Conservation:

PSU’s accomplishments related to Energy Conservation are extensive and include the following major projects.

1. The single pane windows in Pemi Hall were replaced with low E thermal insulated windows that exceed the performance specifications set forth in AAMA 101. Pemi has had a new roof installed including the addition of extra insulation. All new energy efficient lighting with electronic ballasts have been installed throughout the building.
2. Pemi’s steam and condensate lines were replaced and the new piping has been installed in steam tunnels.  This increases energy conservation by reducing heat loss and also extends the lifespan of the materials in use.
3. In Belknap the old 2,500 gallon tank domestic hot water heater was replaced with a more energy efficient semi-instantaneous hot water unit.
4. The recently remodeled Performance Center/Weight Room has all new energy efficient lighting with electronic ballasts.
5. Blair Hall’s 2003 renovation included replacement of old lighting with energy efficient lighting and electronic ballasts throughout the building.
6. In Samuel Reed Hall Hall the original steam heat was replaced with a new more efficient forced hot water system.  Also replaced was the old tank style 2,500 gallon domestic hot water heater with a high efficiency semi-instantaneous hot water heater.  semi-instantaneous hot water heaters have replaced the old large capacity hot water tanks in Boyd Hall, Prospect Hall.
7. A new high efficiency power distribution transformer was installed as a part of the Boyd Hall renovation project as were all new high efficiency lighting fixtures with electronic ballasts.  Automatic occupancy sensors have been used throughout the building’s bathrooms and classrooms areas to conserve electrical as well as heating and cooling energy when these spaces are not occupied.  All new fume hoods are carefully integrated into the building’s complex ventilation system.  These hoods increase the efficiency and safety of indoor air contaminates at the source with specialty exhaust systems.  There are also energy recovery units built in to the outdoor air heating process. In Boyd the cooling tower system is designed to reuse the water supplying the system for a significant reduction in water use.  Also all the water fountains in the building share a shingle central chiller rather than point of use chillers.  All of Boyd’s pumps and motors are variable speed drives which reduce energy consumption.  Boyd Hall cooling systems also use environmentally friendly chiller refrigerants as does Prospect Hall.  The ventilation system is a variable air volume system which increases indoor air quality as well as delivers energy conservation.
8. High efficiency LED exit light systems have been installed in Blair, Hall, Belknap, Pemi, Mary Lyon, Smith and Grafton.
9. Across the campus outside air temperatures are monitored automatically by the energy management system, and as air temperatures fluctuate inside heating and cooling systems are automatically adjusted to compensate and to save energy. This also includes an unoccupied setback mode for buildings when not in use.
10. Lamson Library, Prospect, Boyd, Samuel Reed Hall, Pemi, and Blair Halls have had individual electrical metering installed in order to be able to better measure electrical consumption in the future.
11. New energy efficient window replacement throughout the building has taken place in Russell House, the President’s House, and in Student Apartments many sliding glass doors have been replaced with energy efficient window units.
12. In Prospect Hall the roof has been replaced and increase roof insulation installed.  New high efficiency light fixtures with electronic ballasts and energy conserving LED exit lights have been installed and Variable air volume ventilation systems are in operation.  Energy efficient windows were installed throughout the new addition.  New exhaust and ventilation systems are tied into the energy management system for improved air quality and energy efficiency.
13. During the Lamson remodeling and expansion new energy efficient lighting with electronic ballasts were installed, a portion of the roof was replaced and insulation added. In Lamson also variable speed pumps and drives are in use, LED exit lighting has been installed as well as a semi-instantaneous hot water heater and thermal glass windows.
14. Relighting with energy efficient fluorescents and electronic ballasts have also taken place in Rounds and the Facilities Services Building.
15. In Student Apartments the mechanical rooms were completely retrofitted with new semi-instantaneous water heating units, new condensate pumps, new piping and pipe insulation.
16. In the HUB new energy efficient lighting has been installed and the new variable air volume ventilation system has been added.
17. A campus-wide energy management and building automation system monitors and controls total building temperature, electric and HVAC systems resulting in energy conservation.
18. Silver Cultural Arts Center has had energy efficient lighting installed, LED exit lights and the corridor and lobby lighting has been rewired for better operator control and efficiency.
19. An Energy Recovery Unit was installed in Belknap Hall that will save the University almost $6000 a year by recovering and exchanging energy that would normally have been lost.

Energy-Saving Tips from Information Technology Services:

• Turn off your computer and monitor when not in use for more than an hour.

• Screen savers do not save electricity. Activate automated ‘sleep’ mode after 10-15 minutes of inactivity

• When purchasing new or replacement computers, consider buying efficient flat screens and laptops bearing the 'Energy Star' label.
