This Information Paper demonstrates that there is scope for improving SAP ratings and reducing carbon dioxide emissions during refurbishment of non-traditional and solid wall houses. Non-traditional housing (eg BISF, No Fines, Laing Easiform, Cornish) and pre-1920s solid wall houses are among the most difficult to bring up to modern energy performance standards. Example measures have been modelled on a typical property to demonstrate the carbon savings that are possible by taking a ’whole house’ approach. Other sustainability issues can also be addressed relatively easily during refurbishment, such as renewing windows, kitchens, bathrooms and electrics. This guidance is not restricted to social housing but can be applied to housing across all tenures.
