With possibly the oldest and leakiest housing stocks in western Europe, 29 million homes will need retrofitting before 2050. UKGBC is calling for a nationwide strategy to upgrade 19 million of these homes in the next decade. While there are many challenges associated with an individual home energy retrofit, it is even more difficult retrofitting an entire portfolio of homes. Local authorities and asset managers need a vast amount of data to plan large-scale retrofit initiatives while ensuring that the homes most suitable for retrofit are identified without straining time or resources.
Home Analytics was used to access the current state of the housing stock in the North of Tyne to better inform a business case for a large-scale housing retrofit programme. Each home was classified into one of 67,000 unique archetypes and benchmarked against regional and national trends comparing building fabric, heating systems, SAP characteristics, local area conditions, and deprivation. The Energy Saving Trust’s Portfolio Energy Assessment Tool was then used to model an optimal retrofit for each archetype while providing the anticipated cost, carbon savings, and energy efficiency improvements. A ‘business as usual’ scenario was compared with a Net Zero approach. Data was made available through interactive dashboards alongside a review of the key findings.
