The condition of Scotland’s existing housing stock means that too many households are effectively locked into fuel poverty and domestic properties remain a significant source of carbon emissions. The Scottish Government is committed to removing poor energy efficiency as a driver for fuel poverty and reducing greenhouse gas emissions through more energy efficient buildings and decarbonising our heat supply. These ambitions demand much more than current energy efficiency and fuel poverty schemes. Interventions need to be deeper, available for more archetypes, replicable, affordable, scalable and then delivered at scale.
This study for the Existing Homes Alliance, funded by the European Climate Foundation, reviews the available evidence and recommends priorities for testing deep retrofit approaches in Scotland. These include tenements, the private rented sector and rural cottages. The primary considerations will be to identify whether the approach should be a one-off deep-retrofit solution, or a more staged approach to reach near-zero carbon to ensure that initial incremental measures don’t preclude further measures during the deep-retrofit period.
