Greetings, Net Zero News Community!

We are thrilled to share a groundbreaking initiative that is set to transform the landscape of sustainable living in the UK. The Last Mile group, a consortium of multi-utility infrastructure companies, is pioneering a water-source ambient heat network at the innovative Welborne Garden Village development in Hampshire. This ambitious project not only aims to provide energy-efficient heating solutions but also embodies the spirit of community and sustainability.

A Vision for Sustainable Living

The Welborne Garden Village is a visionary mixed-use development that encompasses up to 700 homes, a primary school, and a vibrant village centre featuring shops, pubs, and cafes. Spearheaded by Buckland Development, this multi-phase project is designed with the future in mind, integrating cutting-edge technology that promotes low-carbon living. The heart of this initiative lies in Last Mile’s new ambient heat network, which promises to deliver significant financial savings and environmental benefits to its residents.

Financial Benefits for Residents

One of the standout features of this heat network is its cost-effectiveness. Residents are expected to save an average of £160 per year on heating costs for a typical three-bedroom house when compared to traditional air-source heat pumps. This not only alleviates financial burdens but also encourages a shift towards more sustainable energy solutions. As we strive for a net-zero future, such initiatives are crucial in making green living accessible to all.

Innovative Technology at Work

The ambient heat network employs a pioneering technology that is the first of its kind in the UK. It harnesses stable temperature water from Portsmouth Water’s nearby underground Hoads Hill Reservoir. This water is then channelled to an energy centre, where a heat exchanger transfers energy from the water into the ambient heat network. Each property within the development is equipped with individual heat pumps that convert this energy into space heating and hot water. This system operates as a closed loop, entirely separate from the drinking water supply, ensuring that there is no risk to water quality.

Maximising Efficiency and Sustainability

What sets this heat network apart is its versatility. During warmer months, the reservoir can function as a heat sink for cooling, while the system facilitates building-to-building heat transfer. This innovative approach allows excess heat generated in one building to be converted into heat and hot water for others, significantly enhancing efficiency. In fact, this system is projected to produce 54% lower CO2 emissions than air-source heat pumps and an impressive 80% less than traditional gas boilers.

A Commitment to Low Carbon Living

Buckland Development, as the master developer of Welborne, has assembled a consortium that is committed to innovating technologies that promote low-carbon living. The project is designed not only to create energy-efficient homes but also to integrate extensive publicly accessible green spaces that enhance the quality of life for all residents. This holistic approach aligns perfectly with the UK’s sustainability goals and sets a benchmark for future developments.

Meeting Future Standards

The Future Homes Standard aims to mandate a reduction in emissions for new homes by 75-80% compared to current building standards. While many developers are grappling with the challenge of meeting these stringent targets, the unique partnership between Last Mile and Rendesco—a design and build partner—addresses these concerns head-on. Last Mile will own and manage the heat network for Phase 1 of the Welborne development, ensuring its efficient operation and long-term viability.

Expert Insight on Ambient Heat Networks

Robin Abram, Associate Director of Last Mile Heat, emphasised the potential of ambient heat networks: “Ambient heat networks – whether using water or ground sources of heat – offer substantial emissions savings. By adopting and managing the completed network, we save developers significant operational expenditure, and in many instances, we can fund the network’s construction, reducing their upfront costs. As developers across the UK are under pressure to meet emissions reduction targets, Welborne Garden Village serves as a blueprint for success that many can follow.”

Operational Excellence and Reliability

Last Mile Heat is a Heat Trust registered supplier, dedicated to owning and operating the network with a focus on reliability and availability. The company employs a dedicated team that utilises 24/7 network monitoring, ensuring that the heat network remains operational and efficient for the benefit of all residents. This commitment to excellence guarantees that the community can enjoy the full advantages of sustainable heating solutions without interruptions.

A Blueprint for the Future

The Welborne Garden Village project exemplifies how innovative infrastructure can facilitate a transition to sustainable living. As we face the challenges of climate change, initiatives like this are essential in demonstrating the viability of low-carbon solutions. The collaboration between developers, utility providers, and local communities will play a crucial role in shaping a greener future for generations to come.

At the Net Zero News Network, we celebrate such inspiring projects that not only contribute to environmental sustainability but also enhance the quality of life for communities. The Welborne Garden Village is a testament to what can be achieved when innovative thinking meets collaborative effort, paving the way for a more sustainable and connected future.

Conclusion: The Path Forward

As we look ahead, the lessons learned from the Welborne Garden Village project can serve as a guide for future developments across the UK and beyond. By embracing innovative technologies and sustainable practices, we can create communities that are not only energy-efficient but also resilient in the face of climate challenges. The journey towards net-zero is a collective endeavour, and with initiatives like Last Mile’s ambient heat network, we are one step closer to realising this vital goal.

Stay tuned for more updates and insights into the latest developments in sustainable living, as we continue to champion the cause of net-zero emissions for a healthier planet.
