Advanced Engineering Economics
With the increased awareness of the environmental sustainability, Energy Efficiency has been regarded as one of the key factors with respect to the greenness of buildings. PSU has committed to contribute this by joining American College and University Presidents’ Climate Commitment community and strive to search for green building or LEEDS certification. However, the old buildings in PSU seems not been received relative attention on improving energy consumption. This led to this project objective of investigating the East Hall, one of the oldest building in PSU on the aspects of energy efficiency and saving. By conducting site survey, collecting market information, and reviewing relevant literature, three Energy Efficiency Measures including Install Occupancy/Vacancy Sensors, Replace mini Refrigerators, and Improve AC system have been identified. For each measure, several options were proposed and analyzed by using Engineering Economics methods such as Present Worth (PW), Annual Worth (AW), and Sensitivity Analysis, in order to investigate the cost and benefit/saving in more detail. The analysis of each Energy efficacy Measure are coupled with sensitivity analysis, which identify the key variables influencing the research results and can be served as an aid for utility management decision.
