PSU’s campus consists of about 60 buildings on 50 acres and PSU’s heating system currently relies on two heating plants with 7 natural gas fired boilers. In addition a 2.5 MW diesel fired turbine was installed in the University’s newest building at 1900 SW Fourth Avenue in 2006. The campus also has a 7 small natural gas fired boilers that serve individual buildings in the area for the PSU residents. On an average PSU’s heating system is required 8 months per year and the approximate operating time for the heating systems is 14 hours a day and 6 days a week. In order to accommodate to the growing demand for hot water and the possibility of using alternative district heating source, PSU is trying to identify and evaluate future fuel sources though an objective process.
