Changeworks is monitoring and evaluating West Highland Housing Association’s Air Source Heat Pump and Sunamp Heat Battery Storage Decarbonation Fund project, funded by the Scottish Government. This project will demonstrate the impact of low carbon heat and Sunamp battery storage in people’s homes and work towards the Energy Efficiency Standard for Social Housing post-2020 (EESSH2). Changeworks will assess the impact of the scheme on householders, monitoring the potential savings and providing crucial data and reporting to determine if these renewables measures should be rolled out more widely to alleviate fuel poverty.
