Abstract
For the awareness of energy conservation and under the pressure of energy-price rising, our government made a lot of efforts in energy-saving and carbon reducing In recent years. This research target on campus building of National Taiwan University (NTU), and aid to (1) making systematize arrangement of energy-saving experience in NTU. (2) Using energy-consumption data of campus building for basic analysis of electrical characteristic. (3) Discussing the status and difficulty of energy-saving practices by expert interviews. (4) Cost-benefit analysis of common energy-saving measures in NTU.
The result shows that the top 10 energy-using buildings in National Taiwan University have a 478.3 EUI value, which is much higher than the standard value of university (98.2). It means NTU still have space to improve energy-saving performance. By expert interview for who in charge of building energy-saving, “building facility replacing subsidy” and “competition of building energy-saving performance” are the major incentives and the major pressure is provided by the “Departments’ electric bill sharing”. Under those policies, most departments take “budget of engineering” and “payback period” as most important concern criteria when choosing energy-saving measures , and “T5 bulb” and “LED fire-caution indicator” are two most common energy-saving measures that be taken. “Not sufficient in budget of facility replacing” and “poor energy-saving conscious of building users” become the greatest challenge to carry energy-saving in NTU.
This research conclude that the critical factor of successful energy-saving is: build up the pay-as-you-go energy bill sharing mechanism, the highly inclination of energy-saving executor, enhance building user’s energy-saving consciousness, speeding up facility replacing and better subsidy diversity. And this research recommend that campus building should replace “T5 bulb” and “LED fire-caution indicator” immediately since they have good energy-saving effect and payback ratio. “Roof insulation” and “motion-sensor in lighting system” need to assess install location carefully to ensure their energy-saving effect. “Replacement of Air-conditioner” has no financial self-liquidating and is suggested keep in normal maintain and eliminate rather than aggressive replacement.
