en.Wedoany.com Reported - UK engineering consultancy Arup and the Ordnance Survey, commissioned by the Department for Energy Security and Net Zero (DESNZ), have completed the latest development of the National Heat Network Zoning Model for England. This model aims to identify areas suitable for building large-scale low-carbon heat networks, helping at least ten towns initiate heat network zoning later this year.
The updated model utilizes geographic data from the Ordnance Survey on buildings, addresses, roads, and rivers to assess regional heat demand and estimate infrastructure development costs. Arup and the Ordnance Survey were first commissioned in 2024 under the Heat Network Zoning Advisory Framework and have now renewed a second contract to further refine the model and verify its reliability.
The system is currently being tested in pilot areas under the Advanced Zoning Programme and will gradually be rolled out nationwide. Stephen Cook, Arup's Urban Energy Lead, stated that heat network zoning will play a key role in expanding resilient and affordable low-carbon heat networks across England, marking a significant milestone in transitioning the plan from design to implementation. Tina Kennedy, Chief Customer Officer at the Ordnance Survey, noted that the organization has been supporting national and local governments and is now becoming an integral part of the development of heat network zoning and the national model design.
Heat networks transport thermal energy from a central heat source to multiple buildings, such as homes, hospitals, and universities, via insulated pipes. Currently, these networks meet approximately 3% of the UK's heat supply, with government targets aiming to increase this to 7% by 2035 and around 20% by 2050.
