Constructing a green, sustainable and environmentally friendly campus comprehensively is always the goal since the establishment of school. With the concepts of looking-forward, innovations, and services, the ideas of integrating with the nature, safety, leisure as well as arts and technology are consistent from the overall plans for campus to the establishment of each public facilities and equipment and learning environment. Over the years, there have been many excellent results in the perspective of constructing green campus with green energy and low carbon footprint.
With the efforts of sustainable principals and actively preparing for funding, energy-saving facilities and equipment were improved and complete campus electricity monitoring and energy-saving management systems were deployed. After reducing contract capacity, installing uninstall functions on host computers, and conducting control of maximum demands, over NT$ 70 million of budget was used in improving the electricity power supply equipment in order to provide complete and stable power supply environment. We were selected as the schools with excel energy-saving performance by Ministry of Economic Affair (Bureau of Energy and Water Resources Agency) and Ministry of Education, and our school was awarded with “Excellence Award” of Energy-Saving Good performance, “Energy-Saving & Innovation Award” and “Outstanding Personnel Contribution Award”.
Our school actively uses the spare roof space to cooperate with the civil societies in promoting energy-saving industry. Renting the roof platform to manufacturers to establish photovoltaic systems could effectively use the properties of campus and also expand the capacity to 496kWp (Totally generated 2.25 million kWh)
Subsidized by Scholarship of Zhuo-Zhang Zong Education Foundation, the construction and equipment of the sustainable, green, smart and future Vision Gallery, built-in heat exchange system for lake water, sun-chasing system, and energy saving air conditioning, smart lighting and energy monitoring system for collecting solar energy could serve as the demonstration platform showing the results of innovations from industry and academics. This could serve as references for industry and academia via the promotion of concepts and techniques for smart energy-saving.
The newly built IER Building has already obtained a Diamond-Level Green Building Candidate Certificate and the certificate for smart building candidate, which made our school a green campus incorporated with the concepts of environmental protection and energy-saving. We will continue to promote public construction combing the principles of environmental protection, ecology, education, practicality and economy. Integration the concepts and approaches of green building will help to implement the building design ideas of sustainable development.
To continuously elevate the level of campus intelligence and construct sustainable excellent environment complying with the requirement of environmental ecology, our school has already planned new energy-saving strategies and smart monitoring system in the future to improve campus intelligence and form institutionalized management. Currently, our school actively applied for the “Demonstration Plans for Sustainable Innovation and Implementation of Smart Community” to Ministry of the Interior (Architecture and Building Research Institute) and has already obtained government grants. In the future, our school will integrate the 4 perspectives of energy saving and carbon reduction, safety monitoring, intelligent traffic and health and comfort to comprehensively integrate the functions so as to form smart management and provide a comfortable, energy-saving, convenient and safe environment.
Environmental and Safety Technology Center is responsible for the processing of sewage in campus to provide reclaimed water for irrigation of flowers and plants in campus and the toilet flushing in student dormitory to save water. Also, rainwater is recycled and reused with certain measures. As for the waste liquid and medicals produced by laboratory, centralized management is the corresponding approach to solve the related problems. In laboratories and training facilities, labeling hazards, determining processing environment, management of dangerous mechanics and equipment as well as the planning, promotion, investigation, suggestion, and supervision stipulated in regulation are implemented to continuously maintain the goal for zero disaster in practice places.
Establishment of friendly campus environment is also one of school goals. Student dormitories were built in campus. As time passed by, some traces were also left in dormitories. Hence, in addition to the continuous improvement in the accessible accommodation space, certain budget is used in the repairs and modification of dormitory every year. There were construction projects that damage the original design pattern in the right side of A1 dormitory building to replant into suite pattern in order to provide boarders with higher accommodation quality. There are independent bathroom amenities, sinks, and air conditioning in each bedroom. This undoubtedly provides boarders with more comfortable environment and also solves the worries and inconveniences of boarders.
1. Good at controlling electricity usage
Since the establishment of our school, we actively promote lots of measures to control and reduce the usage of electricity. As the development of technology, information and communication technology has been introduced into the applications of building energy-saving management. In addition to largely elevating the effects of energy saving, the security and comfort of school life could also be confirmed. Therefore, green building design and systematic smart monitoring management are gradually integrated. Through well-conducted monitoring system to control and supervise the current uses of electricity and coordinate the demands in both peak time and off-peak time to effectively transfer the electricity usage in peak time to elevate the load rates and lower the costs. Campus electricity monitoring and energy-saving management system was established in 2008. In 2014, the system was expanded and improved to strengthen the functions to record the energy usage of each substation in detail; information collected from each substation provided immediate electricity usage data for further analyses and comparison. Collocation with reasonable demanding amount could decrease the over-usage penalty fees and energy charges. For example, the capacity of original electricity contract is 5,300 kW. If the optimal capacity is 4,488 kW after analyzing the electricity usage in recent years, the loads will be preserved to increase the elasticity. Since November, 2014, the electricity usage was lowered to 4, 600 kW. The formerly uninstall functions of central air conditioning host computers in library, administration building and auditorium were installed to conduct maximum demanding amount control to consider both the control and comfort of electricity usage.
2. Elevate efficacy with energy saving equipment
In order to promote sustainable green campus and energy saving and carbon reduction, in addition to the existing environment policies and energy-saving goals in campus, the overall plan and update of facilities and equipment has already laid foundations for the talent education and research and development in green industry; energy audit system also has been implemented. The design of green building was integrated into new construction to elevate or replace existing air conditioning, energy-saving lighting equipment and establish electricity monitoring system; and simultaneously plant the seeds of energy-saving into students’ and faculty’s mind via environmental education in daily life. The major items to elevate the performance of using facilities and equipment are listed below.
a. Establishment of Solar Water Heating System and information center in Student Dormitory A1, A2 and A3.
b. Establishment of heat pump hot water system, 186 T5 high efficiency energy saving lamps and information center in Student Dormitory F.

v. The capacity of electricity contract was lowered from 5,300kW to 4,600kW.
3. Change voltage with substation to make the provision of electricity smarter
Our school was established for decades and many of the original high-voltage electricity equipment (ex. Transformers, high-voltage switch, high-voltage cables, high-voltage capacitors and protective relays) has already reached the life time limits. This not only caused larger energy consumption but also influenced the stability of power supply. As more departments and colleges were established, electricity equipment and devices were procured and the actual electricity usage situations were also adapted. Also, owing to the requirements for high-voltage electricity users stipulated by Taiwan Power Company, the power supply was changed from 11.4kV to 22.8kV, which would cooperate with demands to alter the voltages while supplying electricity to ensure the complete and stable power supply environment.
To stabilize power supply quality and implement the energy-saving ideas to save electricity, our school actively prepares funding for improvement. About NT$ 70 million was budgeted to promote the electricity voltage-altering operation in campus and high-efficiency electric equipment for high-voltage electricity would be simultaneously applied in higher priority to reduce the loss of power wires, copper loss of main transformer, and copper and iron loss of transformer in buildings so as to save electricity consumption and reduce CO2 emissions to reach the effect of energy saving and carbon reduction.
Currently, our school has completed the related operations for the voltage-alteration of high-voltage equipment in northern campus. Also, the transformers of high voltage cubicles in Design Building 2 were updated from 750kVA to 500kVA and were connected via second time side TIE. Design Building 1 used two of the existing 750kVA transformers and connected via second time side TIE to lower the iron loss, which saved about 49.337 kWp of electricity and about 162.8 thousand NTDs every year. In south campus, Buildings 1, 2 and3 of College of Design, College of Humanities and the voltage-altering works in Humanities Building were continually completed to fully maximize the energy-saving efficiency and ensure electrical safety.
In addition to actively renew and improve energy-saving equipment in campus, electricity monitoring and energy-saving management system were also established to record the data of electricity uses in each substation in detail to allow the analyses and control of electricity uses. Analyzed data and information could serve as reference to determine whether the contract capacity should be lowered. Installation of air conditioning formerly uninstalled functions in monitoring system could facilitate the highest demanding amount supervision in different stages. When the load demands exceed certain set values (ex. 4,300kW or 4,600kW), the air conditioning of library, Administration Building, and Auditorium will be switched off (uninstallation) orderly in different stages.
4. Sustainable, green, smart and innovative future Vision Gallery
To provide a space for exhibiting the innovations energy-saving lectures and energy saving results, our school self-raised funds and adding NT$ 15 millions of donation from Scholarship of Zhuo-Zhang Zong Education Foundation to invest 30 million dollars to build a sustainable, green and smart Vision Gallery next to Yun Meng Lake, which utilizes the functions of the lake and pools to design waterfront ecology, rainwater recovery, heat exchange system of lake and ground water, photovoltaic system, sun-chasing system, energy saving air conditioning, and energy monitoring system , etc. to serve as the demonstration platform for innovations of industry and academia. Cross-domain green low-carbon technology and innovations were also integrated in the implementations of green energy, smart energy-saving and the researches, development, and lecturing of smart green building to cultivate talents for green smart innovations. Besides, YunTech serves as fields to practice and experience cross-domain “Green Tech Program” and” Energy & Electricity Saving Program”, and shows the results of innovations from industry and academics. This could serve as references for industry and academia via the promotion of concepts and techniques of smart energy-saving.
5. Good energy saving efficacy makes the sustainable environment possible
a. In response to the teaching demands, new schoolhouses were continuously built and the floor areas also gradually increased year by year. In cooperation with Executive Yuan to implement “Comprehensive Energy Saving and Carbon Reduction Measures for Government Agencies and Schools” and “Four Saving Items (saving electricity, saving oil, saving water, and saving papers) Projects for Government Agencies and Schools”, the electricity using amount of our school has always showed negative growth since 2007 and was much better than the requirements in Four Saving Items Project. Furthermore, the average electricity usage of each person every year as well as the electricity usage per unit floor areas also showed decreasing trends.
b. Sewage treatment plant, which recycled water to reuse in watering, landscaping, and firefighting, was built in the early stage of our school establishment. The water reuse rate is about 60% to 70%. This not only helps the greening and landscaping of campus but also effectively saves the usage of running water. Our campus thus could be regarded as the model school showing the results of saving water and energy as well as reducing carbon footprint. Moreover, the average electricity usage per person every year and the electricity usage per unit floor areas also showed decreasing trends yearly.
1. The floor areas of schoolhouses
In 2012, after the construction of Engineering Building 6 was completed, construction of Technical and Vocational Building, Management Building 1, Vision Gallery, Language Center and IDF YunTech also increased floor areas up to 2307.21 square meters in total to expand teaching spaces and improve the functions of old schoolhouses. Now the total areas for schoolhouses are 269,868 square meters.
2. Diamond-level green building developed via industry-university cooperation
To develop the mission for model university of science and technology project to strengthen the connections between industry and academics via infrastructure and to fully cater to the demands of industrial and commercial development as well as talent needs in both domestic and foreign industry, our school built IER Building with both the funds from Ministry of Education and self-raised funds. The total budget for the construction of I YunTech RR Building is 418.561 million NTDs and the scale of the building includes 1 underground floor and 8 floors above ground with totally13, 846 square meters. There will be achievements exhibition space, multifunction practice factory, technical information and innovative center, industry association, incubation center for academia-industry collaboration and intellectual property, factory incubation room, student micro-enterprise incubation room, trial-production center for R&D outcomes, product testing center, specific production line simulation facilities, technology school innovation and entrepreneurship platform in central region in the internal space to serve as YunTech’s windows of academics to the industry for application researches and connections with the industry.
To continuously promote green campus with the ideas of environmental protection and energy-saving, YunTech IER Building could serve as fields to practice and experience cross-domain “Green Tech Program” and” Clean green sustainable science and technology Program”. YunTech has already obtained a Diamond-Level Green Building Candidate Certificate and displayed the innovative results and promoting the best model. The indications include 9 indexes:
