What is retrofit?

Retrofit refers to the strategic improvement of existing buildings, so that they are better able to meet modern energy efficiency standards. It can involve installing a new low to zero-emissions heating system in a building or simply adding double glazing, with the common aim of decreasing energy consumption and reducing carbon emission outputs from homes. 

Overcoming the challenges of retrofitting traditional buildings

Energy efficiency and retrofit pose a significant obstacle for owners living in traditional tenement buildings. How can Scotland overcome these obstacles? Professor in Housing Economics (Urban Studies) at the University of Glasgow, Kenneth Gibb, writing in People, Place and Policy (PPP), has looked closely at the issues of delivering retrofit in the context of Scotland’s traditional housing stock and its targets for net zero.


Retrofitting is the process of modifying a building after it has been built.
