Energy Efficient Appliances Usage

Energy efficiency label: Level 1 energy efficiency label, eco-label and Energy Star standards 

Library's Chiller and Related Facilities 

The Establishment of Intelligent Street Lights 

LED with motion senser dimmer in offices and classrooms, heat pump and EMS 

Room/Center Air Conditioners in classrooms and library

Use of smart meters and digital power managemant systems in campuses 

        In terms of energy conservation, the university first stipulates that all purchased electrical appliances must conform to the Level 1 energy efficiency label and the Energy Star standards for power consumption. 

        To reduce the energy consumption of the aging chiller in the Library and Information Building, in 2022, the library's chiller and related facilities were replaced. The new system is smartly connected with surrounding facilities and integrates an ICT monitoring system for efficient operation management. Through this monitoring system, in-depth insights into the chiller's operational status, such as cooling water temperature, water flow rate monitoring, and high/low and medium pressure monitoring, are obtained. The real-time performance of the chiller is displayed, serving as a crucial reference for subsequent maintenance. Furthermore, the newly installed chiller system is connected to the existing solar power generation system and energy storage cabinet on the rooftop of the Library and Information Building. It operates in conjunction with the energy management system (EMS), achieving an effective energy management strategy of “peak shaving and valley filling”.  After replacing this chiller, a third-party impartial entity inspected and confirmed that its energy-saving efficiency reached 42%.

        In addition, National Chiayi University continued to replace the old T8/T5 lights with LED lights (No halogen bulb allowed in campus), while also securing funding to replace energy-consuming air conditioners. The campus has a total of four smart streetlight control circuits, and based on needs, 104 old-fashioned streetlights were replaced. Furthermore, to more efficiently manage water resources, the university secured funding to install 88 smart water meters and a water resource management platform, aiming to reduce the frequency of electricity use for groundwater extraction and minimize energy consumption.  The percentage of nergy efficient appliances Usage is reach to 85.7 %.
