This project, delivered by Scene Connect for South West Net Zero Hub in partnership with Plymouth City Council and Plymouth Community Homes, represents a leading-edge research study into the relative feasibility of low carbon heating options (LCHO) within Plymouth’s Heat Network Zoning Advanced Pilot.
Rather than relying on traditional, assumption-led energy options appraisals, the study applied a high-resolution, data-driven methodology using Scene’s Shared Works platform and advanced building physics modelling. This enabled the simulation of hundreds of individual dwellings across multiple archetypes, capturing real variation in fabric, orientation, occupancy behaviour and thermal performance. This granular approach fundamentally challenges standardised modelling practices, producing a more accurate and investment-ready understanding of heat demand, system performance and user interaction.
The research tested the technical and financial feasibility of heat networks against alternative low carbon solutions, including air- and ground-source heat pumps and direct electric systems. It demonstrated that heat networks, particularly within designated zones, offer a strategically aligned and scalable solution, but are highly sensitive to connection costs, delivery models and subsidy requirements.
For the funder, the project provides critical evidence to support zoning policy, infrastructure prioritisation and market shaping. For delivery partners, it establishes clear, archetype-led pathways to decarbonisation, balancing carbon reduction, resident affordability and long-term asset strategy.
As a research output, the project sets a new benchmark for heat decarbonisation appraisal - bridging policy, modelling and real-world delivery to enable confident, data-led investment decisions at scale.
