SDG Impact Detail

Have plans to upgrade existing buildings to higher energy efficiency.

Prince of Songkla University (PSU) has established a policy framework and ongoing measures to improve the energy performance of existing university buildings. These efforts support the University’s broader commitment to sustainable campus development, efficient energy use and the transition toward a low-carbon university.

Policy Framework for Building Energy Efficiency

PSU has implemented the Policy on Energy-Efficient Building Renovation and Construction B.E. 2566 (2023) as a framework for improving energy performance in both existing and future university buildings.

The policy promotes the planning and control of energy use within buildings, the use of energy-efficient equipment and environmentally responsible materials, and the design of buildings that make better use of natural ventilation and daylight. It also promotes compliance with national green-building requirements and recognised assessment frameworks, including the Government Green Building criteria and the Thai’s Rating of Energy and Environmental Sustainability (TREES).

This policy provides the institutional basis for PSU to progressively improve the energy efficiency of its existing building stock.

Improving the Energy Performance of Existing Buildings

PSU has already implemented energy and environmental management measures in existing buildings through the Green Office programme.

In 2025, PSU Pattani Campus had 27 buildings certified under the Green Office standard, including:

• 1 Platinum-level building – Building 66, Faculty of Communication Sciences

• 26 Gold-level buildings – including 11 buildings within the Faculty of Science and Technology and 15 campus administrative and service buildings.

The Green Office standard includes requirements related to resource and energy management and therefore provides an operational mechanism for improving the energy and environmental performance of buildings already in use.

Using Energy Data to Guide Future Building Upgrades

PSU monitors electricity consumption at both university and campus levels to support energy-management planning.

Total university electricity consumption was:

• 2023: 79,021,680.00 kWh

• 2024: 83,863,600.00 kWh

• 2025: 100,467,532.75 kWh

In 2025, electricity consumption was also monitored separately across the five campuses:

This energy-use information provides an important evidence base for identifying campuses and building groups where further energy-efficiency improvements should be prioritised.

Planned Direction for Existing-Building Energy Improvement

Building on the University’s energy-efficient building policy, Green Office implementation and energy-consumption monitoring, PSU continues to strengthen the energy performance of existing buildings through a phased approach.

Future improvement measures are expected to focus on areas such as:

• upgrading inefficient lighting and electrical equipment;

• improving the performance of air-conditioning and cooling systems;

• strengthening building-level energy monitoring;

• improving building operations and energy-management practices;

• applying energy-efficiency and green-building standards to renovation projects; and

• prioritising buildings or building groups with relatively high energy consumption for further review and improvement.

Where appropriate, building upgrades are also expected to be aligned with recognised energy-conservation and green-building standards.

Moving Toward a More Energy-Efficient Campus

PSU’s approach combines institutional policy, energy-use monitoring and improvement of existing building operations. The certification of existing buildings under the Green Office programme demonstrates that energy and environmental performance improvements are already being implemented, while university-wide electricity monitoring provides the basis for identifying future priorities.

PSU will continue to strengthen this approach by expanding building-level energy monitoring, identifying high-energy-use buildings and developing phased energy-efficiency improvement measures across its campuses.
