As we look toward the future of the education sector, the need to prioritise sustainable design and green credentials becomes ever more pressing. We know that schools are so much more than mere educational facilities; they are at the heart of our communities, playing a vital role in shaping future generations. With climate change posing numerous global challenges, inaction is no longer an option. We must ensure that the necessary carbon reduction strategies are embedded into the design of educational spaces, developing the low-carbon schools of tomorrow.

At Bouygues UK, our vision is clear: to create inspiring places to learn while significantly reducing our environmental impact. With decades of experience building schools for the Department for Education (DfE) and other clients delivering the UK’s education agenda, we have always placed sustainability, social value, and standardisation at the core of our operations. Now, as we all focus on achieving net zero carbon emissions, our commitment to creating energy-efficient, low-carbon educational facilities has only deepened.

Embracing timber through our WeWood initiative

One of the most exciting advancements in our approach to constructing the schools of the future is our WeWood initiative. This initiative, which spans across Bouygues Construction’s global operations, aims to accelerate the use of timber in the buildings we deliver, including those in the education sector. Timber is not just a renewable resource; it is a material that significantly reduces the embodied carbon in construction. By substituting timber for more carbon-intensive materials like concrete and steel, we can make substantial strides in lowering the carbon footprint of new school buildings.

Timber’s benefits extend beyond its sustainability credentials. The material offers flexibility in design, allowing us to create unique educational spaces that reflect the ethos and identity of each school. By integrating timber into our standardised design model, we are able to offer schools a product that is both environmentally friendly and tailored to their specific needs.

The WeWood initiative also fosters strong collaboration with our clients and supply chain. By partnering with key players in the timber sector and forging innovative construction methods, we are able to deliver comprehensive solutions that go beyond just the structure of the building. For example, in collaboration with Bouygues Bâtiment France and Technologies & Habitats (T&H), we have been able to develop a timber solution where wooden classroom modules are prefabricated off-site. These modules are pre-equipped with essential services, allowing for a seamless integration into the broader school infrastructure. This method not only reduces construction time but also enhances the quality and sustainability of the finished product.

Our new project for St John’s Academy is an apt example of how we are using timber as part of our commitment to both education and sustainability. Bouygues UK will be using sustainable, low carbon materials as part of the build, including a cross-laminated timber frame.

This two-storey building will feature a green roof with photovoltaic panels. The grass playing fields and MUGA will also have extensive SUDs (sustainable draining systems) featuring attenuation, swales and porous parking areas.

The buildings will also be clad in brickwork and timber panelling with feature aluminium framed entrances.

Innovating with off-site construction

The use of timber is just one aspect of our broader strategy to reduce carbon emissions through innovative construction methods. Off-site manufacturing plays a significant role in this approach. By constructing large portions of buildings in a controlled factory environment, we can reduce waste, improve quality control, and significantly cut down on the carbon emissions associated with traditional on-site construction methods.

Bouygues Construction’s work on projects like the Collège Revaison in Saint-Priest, France, showcases the potential of this approach. In this project, 90% of the school was constructed using timber, with 50% of the building being modular. The 100 wooden modules that make up the school were manufactured off-site before being assembled on location. This method not only reduced the project’s carbon footprint but also ensured a faster and more efficient construction process.

Similarly, Bouygues Construction projects in Pithiviers and Dadonville, France, demonstrate how bio-sourced materials like timber, straw, and hemp can be used in combination to create educational facilities that meet the highest environmental standards. These schools are not only designed to be net zero in operation but also serve as benchmarks for high-quality, environmentally friendly construction.

Bouygues UK will also be using an enhanced quality construction approach through consistent off-site manufacturing, to reduce waste and defects on St John’s Academy.

A holistic approach to sustainable design

While the use of timber and off-site construction methods are central to our approach, we also recognise the importance of a holistic design strategy that addresses every aspect of a building’s environmental impact. This includes everything from the orientation of the building to maximise natural light, to the integration of natural ventilation strategies to ensure a comfortable learning environment without the need for energy-intensive cooling systems.

Our standardised model school approach, which aligns with the DfE’s output specifications, is designed to be net zero carbon in operation. By focusing on maximising natural light, optimising energy performance, and reducing embodied carbon, we can create educational facilities that are both sustainable and cost-efficient.

This approach does not mean sacrificing the uniqueness of each school. Instead, through the use of flexible design elements and a variety of materials, we can ensure that each school we build is a reflection of its community’s identity and needs.

Future-proofing education

As we move forward, the schools of tomorrow must be designed not just to meet today’s standards but to anticipate future needs. This means embracing technologies that allow for real-time monitoring and modelling of building performance, ensuring that the spaces we create are as energy-efficient and sustainable as possible throughout their lifecycle. By standardising our construction methods and integrating innovative solutions like BIM (Building Information Modelling), we are future-proofing our schools, making them adaptable to changing technologies and educational needs.

At Bouygues UK, we are committed to leading the way in creating the low-carbon schools of tomorrow. By prioritising sustainability in every aspect of our work—from the materials we use to the methods we employ—we are building a better future for the next generation. We are proud to be demonstrating just how possible it is to create world-class educational facilities that are both environmentally responsible and inspiring places to learn.
