What are measures?
retrofit measure is a change to an existing building that seeks to improve its performance, in terms
of energy use and its associated CO2 emissions. In doing so the building’s environmental, comfort and aesthetic conditions may be affected. Measures can
affect changes to the building’s structural elements (fabric), changes to the building’s engineering systems providing heating, lighting and power, water, air supply and extract, or its energy supply (services) or changes to the way in which people interact with the building (behaviour).
