As universities continue to expand their educational, research, and support facilities, the construction of new buildings presents an important opportunity to integrate sustainability into long-term campus development. New buildings can have significant impacts on energy and water consumption, material use, waste generation, greenhouse gas emissions, and the surrounding environment throughout their life cycle. Therefore, incorporating sustainable standards from the planning and design stages is essential to ensure that campus development supports environmental responsibility while providing safe, healthy, accessible, and efficient spaces for students, staff, and the wider university community.
Walailak University recognizes that sustainable building development is an important component of responsible campus planning. Rather than considering sustainability only after construction is completed, the University seeks to incorporate sustainable principles into the development of new buildings from the outset. This includes consideration of energy and resource efficiency, appropriate use of materials, environmental impacts, accessibility, indoor environmental quality, and the long-term operational performance of buildings.
Implementing sustainable standards in new building construction also contributes to the University’s broader commitment to sustainable development. Well-designed buildings can reduce resource consumption and operating costs, improve the quality and comfort of learning and working environments, and enhance the resilience of the campus to future environmental challenges. By integrating sustainability into new construction, Walailak University aims to ensure that the expansion of its physical infrastructure is consistent with its responsibility to protect the environment and create a sustainable campus for present and future generations.
In 2025, Walailak University incorporated sustainable principles into the construction of new buildings and the renovation of existing facilities by selecting environmentally responsible materials and integrating energy-efficient design features. These approaches aim to reduce the environmental impacts associated with construction and building operations while improving energy efficiency, indoor environmental quality, user comfort, and the long-term durability of university facilities.
Key sustainable elements incorporated into WU’s building development include the use of hydraulic cement, metal sheet roofing, green bar steel, natural daylight utilization, and energy-efficient LED lighting systems. The University also considers relevant engineering and building standards, including the standards of the Engineering Institute of Thailand (EIT) and the Building Energy Code (BEC), to support safe, efficient, and sustainable building design and construction.
By integrating sustainable materials and design considerations from the construction and renovation stages, Walailak University seeks to ensure that the development of its physical infrastructure contributes to more efficient resource use, reduced energy consumption, and a healthier and more comfortable campus environment. These measures also support the University’s long-term commitment to sustainable campus development, ensuring that new and improved facilities can serve the university community effectively while reducing their environmental footprint.
Hydraulic and Low-Carbon Green Cement
Walailak University has incorporated hydraulic cement and low-carbon green cement into the construction of its new buildings and the renovation of existing buildings across the campus. This approach reflects the University’s effort to reduce the environmental impacts of construction while maintaining the structural strength, durability, and long-term performance required for university facilities.
Low-carbon green cement can reduce the carbon footprint associated with cement production by using alternative materials, such as fly ash and blast-furnace slag, to partially replace conventional clinker. Depending on the formulation and production process, low-carbon cement can significantly reduce CO₂ emissions compared with conventional cement while maintaining the strength and durability required for construction. Its use therefore helps reduce the embodied carbon of buildings and supports more environmentally responsible construction practices.
The use of hydraulic and low-carbon cement also contributes to the long-term sustainability of university infrastructure. Durable construction materials can extend the service life of buildings and reduce the need for frequent repairs, replacement materials, and associated construction activities. By applying these materials to both new construction and the renovation of existing facilities, Walailak University is integrating lower-carbon and resource-efficient practices throughout the development and improvement of its campus infrastructure.
These practices demonstrate the University’s commitment to reducing the environmental footprint of its buildings while ensuring that campus facilities remain safe, durable, functional, and suitable for long-term use.
Metal Sheet Roofs
New buildings at Walailak University incorporate metal sheet roofing systems designed to improve thermal performance and reduce heat transfer into occupied spaces. The roofs are equipped with heat-reflective coatings, while insulation is installed beneath the roofing to provide an additional barrier against solar heat gain. Together, these measures help prevent excessive heat from entering the buildings, particularly under Thailand’s hot and sunny climate.
By reducing the amount of heat transferred into indoor spaces, the combination of reflective roofing and insulation can reduce the cooling load required from air-conditioning systems. This contributes to more efficient energy use and can help lower the greenhouse gas emissions associated with building operations. At the same time, maintaining a more stable indoor temperature can improve thermal comfort for students, staff, and other building users.
The use of these roofing measures demonstrates how WU integrates passive energy-efficiency considerations into new building design. Rather than relying solely on mechanical cooling, the buildings incorporate materials and design features that help manage solar heat from the outset, supporting more efficient, comfortable, and environmentally responsible campus facilities.
Natural Lighting and Energy Efficiency
Walailak University has incorporated natural daylighting features into selected areas of its new buildings to reduce the need for artificial lighting during daytime hours. Clear fiberglass roof panels and transparent sectional doors allow natural light to penetrate indoor spaces, providing sufficient illumination while making better use of the surrounding natural environment.
Maximizing the use of daylight can reduce reliance on electric lighting and consequently lower electricity consumption and the associated carbon emissions from building operations. It can also contribute to a more pleasant and comfortable indoor environment by providing occupants with access to natural light during the day.
The integration of daylighting features demonstrates WU’s approach to combining architectural design with energy-efficiency considerations. By making use of available natural light alongside energy-efficient lighting systems, the University can reduce unnecessary energy use while creating functional and comfortable spaces for students, staff, and other building users. This approach supports the development of more resource-efficient and environmentally responsible campus facilities.
Green Steel for Lower-Carbon Construction
Walailak University has incorporated sustainable reinforcing steel, or Green Steel, into its building construction as part of its efforts to reduce the environmental impacts associated with structural materials. The Green Steel used by the University is produced using Electric Arc Furnace (EAF) technology, with 100% recycled scrap steel as the raw material. Compared with conventional steel production processes, this approach can reduce greenhouse gas emissions by approximately 50–75%, helping to lower the embodied carbon associated with building construction.
The use of high-strength SD50 reinforcing steel also contributes to material efficiency. Its higher strength can reduce the amount of reinforcing steel required for structural elements such as columns, beams, and foundations by up to 20%, while maintaining the required structural performance. Using less material can further reduce the environmental impacts associated with the production, transportation, and installation of construction materials.
In addition, WU uses pre-cut and pre-bent reinforcing steel (Cut & Bend), which can reduce steel off-cuts and construction waste generated on site by approximately 10–15%. Preparing steel components to the required specifications before delivery also helps improve construction efficiency, reduce material wastage, and save time and labor during installation.
Through the use of recycled-content Green Steel, high-strength reinforcing materials, and pre-fabricated Cut & Bend processes, Walailak University is integrating resource efficiency and lower-carbon construction practices into its building development. These measures contribute not only to reducing the environmental footprint of construction but also to improving material efficiency and supporting more sustainable use of resources across the campus.
Energy-Efficient LED Lighting
In 2025, Walailak University incorporated energy-efficient LED lighting into its facilities, including the Tumpang Museum, where warm-white/orange LED bulbs were adopted as part of the museum’s lighting design. The use of LED technology provides an energy-efficient alternative to conventional fluorescent and other less efficient lighting systems, helping to reduce electricity consumption while providing effective illumination for indoor spaces.
LED lamps generally have a longer operational lifespan and require less frequent replacement than conventional lighting. This can reduce maintenance requirements, the consumption of replacement materials, and waste generated from discarded lamps. LED lighting also avoids the mercury associated with fluorescent lamps, supporting safer and more environmentally responsible lighting practices.
At the Tumpang Museum, the warm/orange tone of the LED lighting also complements the character of the museum environment by creating a warm and welcoming atmosphere for visitors while maintaining the energy-efficiency benefits of LED technology. The integration of efficient lighting demonstrates how WU can combine environmental considerations with the functional and aesthetic requirements of its facilities.
Through the adoption of LED lighting, Walailak University is improving the energy performance of its buildings while reducing operational impacts and supporting more sustainable campus infrastructure.
Sustainable Timber for Traditional Southern Architecture
Walailak University incorporated sustainable material selection into the construction of a traditional Southern Thai house at the Tumpang Museum, combining cultural preservation with environmentally responsible building practices. The house was constructed using timber and sustainable alternative materials selected with consideration for their carbon footprint, environmental impacts, and potential for responsible replacement and regeneration.
Where timber is used, the University prioritizes wood sourced from plantation forests rather than relying on timber harvested from natural forests. Plantation-grown timber can help reduce pressure on natural forest ecosystems while providing a renewable source of construction material when forests are responsibly managed and replanted. In addition, wood stores carbon absorbed by trees during their growth, allowing part of that carbon to remain stored in the material throughout the building’s useful life.
The approach demonstrates that the preservation of traditional architectural forms can be combined with contemporary principles of sustainable construction. By selecting renewable and lower-carbon materials while avoiding unnecessary impacts on natural forests, the traditional Southern house provides both a cultural learning space and an example of how heritage-inspired architecture can support environmental responsibility.
Through this project, Walailak University demonstrates an integrated approach to sustainable campus development in which cultural heritage, responsible material sourcing, carbon reduction, and long-term resource conservation are considered together.
Solar Energy for Sustainable Building Operations
In 2025, Walailak University’s Center for Scientific and Technological Equipment continued to utilize solar panels as part of its efforts to increase the use of renewable energy and reduce reliance on electricity from conventional energy sources. Solar panels installed at the Center convert sunlight into electricity that can be used to support the operation of its facilities and scientific equipment.
The continued use of solar energy helps reduce the amount of electricity that needs to be supplied from conventional sources, contributing to lower energy consumption and reducing the greenhouse gas emissions associated with electricity generation. As solar energy is a renewable resource, its integration into campus facilities also supports the University’s efforts to diversify its energy sources and improve the long-term sustainability of building operations.
The application of solar panels at the Center for Scientific and Technological Equipment demonstrates how renewable energy can be incorporated into existing university infrastructure. By continuing to utilize solar power, WU is taking practical steps toward improving energy efficiency, reducing the environmental footprint of its facilities, and supporting the transition toward a more sustainable campus.
The integration of sustainable standards, materials, and technologies into new building construction and renovation enables Walailak University to reduce the environmental impacts associated with the development and operation of its campus facilities. The use of low-carbon cement and recycled-content Green Steel helps reduce embodied carbon and improve material efficiency, while responsible timber sourcing supports the conservation of natural forests. Energy-efficient features, including reflective roofing, insulation, natural daylighting, LED lighting, and solar energy systems, further contribute to reducing electricity consumption and the carbon emissions associated with building operations.
These measures also provide long-term benefits for the University and its community. More energy- and resource-efficient buildings can help reduce operating and maintenance requirements while improving indoor environmental conditions and occupant comfort. The use of durable and efficient materials can extend the service life of facilities, reduce the need for frequent replacement and repairs, and minimize construction-related waste over time. At the same time, incorporating renewable energy and lower-carbon materials strengthens the University’s resilience to future energy and environmental challenges.
Beyond individual buildings, these practices contribute to the development of a more sustainable university campus. By considering environmental impacts from the planning and construction stages through to long-term building operation, Walailak University demonstrates that campus expansion and infrastructure development can be pursued while maintaining environmental responsibility. These efforts support more efficient use of natural resources, lower greenhouse gas emissions, and a healthier and more sustainable environment for students, staff, visitors, and future generations.
