1.Policy Objective

In line with the University’s Environmental Protection and Occupational Safety and Health Management Policy, National Tsing Hua University (NTHU) is committed to building a sustainable and environmentally responsible campus. The University continuously promotes energy conservation and resource circularity to reduce freshwater consumption, enhance water reuse efficiency, and strengthen long-term sustainable water management in response to climate change and regional water challenges in Taiwan.

2.Policy Principles

·        ● Sustainability Governance

　 A cross-departmental governance mechanism, led by the Energy Conservation Task Force, shall review water use and reuse performance on a regular basis.

·        ● Source Reduction

　 All campus facilities conduct regular inspections of water tanks and supply systems to prevent leakage and ensure the operation of water-saving devices.

·        ●Reuse Priority

　Reclaimed water from swimming pools, rainwater harvesting systems, and open water bodies shall be prioritized for landscape irrigation and ecological pond replenishment.

·        ●Green Procurement

　Procurement of products and devices with eco-labels and water-saving certifications shall be prioritized.

·        ● Education and Awareness

　 Water conservation campaigns and educational programs shall be continuously promoted to engage faculty, staff, and students.

3.Implementation Measures

·        ● Swimming Pool Water Reuse

　Recycled pool water is used for track field irrigation at the main campus and ecological pond replenishment at the Nanda campus, totaling approximately 1,044 tons annually.

·        ● Rainwater and Open Water Reuse

　All post-2000 buildings certified as green buildings reuse rooftop rainwater for irrigation and toilet flushing; open water sources such as Chenggong Lake support approximately 24 tons of landscape irrigation annually.

·        ● Water-Saving Infrastructure

　All campus facilities are equipped with water-saving faucets and automatic shut-off devices to minimize waste.

·        ● Energy and Water Management Meetings

　Annual meetings of the Energy Conservation Task Force review progress on energy efficiency and water reuse.

·        ● Landscape and Ecological Stewardship

　The Campus Landscape and Environmental Review Committee ensures ecological harmony in construction and irrigation planning based on local topography and groundwater conditions.

4.Policy Outcomes

- Over 1,000 tons of reclaimed water reused annually.

- All new buildings certified under green building standards.

- Comprehensive water-saving infrastructure implemented campus-wide.

- Ongoing education and advocacy programs strengthen environmental awareness among the campus community.

5.Continuous Improvement and Monitoring

NTHU will continuously monitor water reuse performance through a smart water management system, enhance data governance and decision-making support, and regularly disclose progress through the University’s annual sustainability report to ensure transparency and accountability.
