Retrofit programme will help make existing Welsh homes more energy-efficient - Coastal Housing Group

A major consortium including Coastal Housing alongside other 25 social landlords in Wales has won £7m Welsh Government funding to deliver an optimised retrofit programme across more than 1,300 Welsh homes, making them more energy-efficient and cheaper to run.

As well as decarbonising more than 1,370 Pathfinder homes, this project will create the tools required to roll out further decarbonisation of more homes across Wales in future.

The Optimised Retrofit approach will deliver a whole house, pragmatic route to decarbonising existing homes. The pathfinder programme will use a combination of building fabric improvements, low and zero carbon technologies (such as solar panels, battery storage and heat pumps), and intelligent ongoing operational controls, to take each home to its lowest achievable carbon footprint.

The approach is designed to support incremental home upgrades over multiple steps, in a coordinated way. The scheme enables delivery of a more comprehensive level of genuine zero carbon, typically for less cost, by supporting and aligning with the decarbonisation of the energy grids that will take place over the coming decades. This complexity is then rationalised into a simple ‘Zero Carbon by…’ forecast year – the year that individual home is expected to achieve net zero operational carbon emissions.

As well as social housing providers, this large-scale collaboration of partners includes a range of research, innovation, academic, technology, energy and industry organisations from across the UK. Alongside providing supplier and employment opportunities across Wales, these will lead supporting activities such as cutting-edge research, training and upskilling, and establishing frameworks for the retrofit industry, to enable the Welsh economy to become a true leader in decarbonisation.

Representing over half the social housing stock in Wales, the Optimised Retrofit collaboration will use the Pathfinder homes to refine a range of digital tools that enable each home to be easily and quickly surveyed, and ‘Pathways to Zero’’ carbon identified. This includes forecasting the year that each home will achieve zero carbon, based on the recommended stepped improvements, as the grid becomes greener.

Following the completion of the Optimised Retrofit Pathways programme, these digital tools will be made available to Welsh social housing providers, academia, government, and subsequently private homeowners. This will enable the long-term delivery of a legacy of tools, skills, frameworks and an evidence base that will allow others to follow and enable the decarbonisation of Wales’ homes to quickly gain scale and pace.

The funding has been awarded through the Welsh Government’s Optimised Retrofit Programme that was introduced this year as part of the Innovative Housing Programme, to help reduce the carbon footprint of existing social housing in Wales, make energy bills more manageable for residents and provide new job and training opportunities.
