Scottish-headquartered climate tech company, IES, has created a digital twin of the entire Stirling & Clackmannanshire region, informing an energy masterplan to map its pathway to becoming a carbon-neutral city region.

A digital twin is a dynamic virtual replica of a real-world object – in this case a region – which enables users to test, model, and refine different parameters in real time. In the case of buildings, these factors can include energy usage, renewable energy generation, and heat networks, amongst others.

Deploying its cutting-edge technology, IES developed a digital twin for Stirling and Clackmannanshire Councils that covered 3D geometries for every building in the entire region, which spans 2,413 square kilometres. The digital model considers a plethora of factors which affect energy efficiency and emissions, from building fabrics and heating systems to fuel types and usages.

Taking into account both national and regional targets, the digital twin provided evidence-based projections of future energy demands and emissions, helping to inform a pathway to reach a net zero energy system across the region.

The Regional Energy Masterplan spans four stages between 2023 and 2045, covering energy efficiency, heat management, and energy generation. Founded on evidence from the digital twin, it underlines which – and in what order – low-carbon energy systems should be deployed across the region to create the most effective results from economic, environmental, and social sustainability perspectives.

IES’ simulations uncovered that carbon emissions produced by the energy used to heat and power the region’s domestic and non-domestic buildings can be reduced by approximately 98% by 2045, when compared against a 2022 baseline, through the actions and projects identified.

Craig McKendrick, public sector lead at global climate tech company, IES, said: “In a world where energy is vulnerable to socioeconomic and geopolitical factors, and we’re increasingly aware of our climate emergency, energy planning is a major public sector priority.

“The decisions we make now need to look at the long-term and be informed by the data. Accessing the evidence that intelligent tech now affords can be a game-changer when it comes to planning the route to improved efficiency and reduced emissions.

“This project is a great example of two forward-thinking local authorities choosing to act on insight and ready themselves for the transition the region will need to go through over the course of the next two decades.

“By creating a digital twin of the entire Stirling & Clackmannanshire region, we can see how things are actually working in practice and identify what could be done to make the biggest impact in the most efficient way. It also helps us to model a range of prospective scenarios, identifying potential risks and barriers that could crop up along the journey to 2045.”
