Retrofitting means ‘…providing something with a component or feature not fitted during manufacture or adding something that it did not have when first constructed’ (Ref Retrofit 2050: Critical challenges for urban transitions). It is often used in relation to the installation of new building systems, such as heating systems, but it might also refer to the fabric of a building, for example, retrofitting insulation or double glazing.
Retrofitting has come to prominence in recent years as part of the drive to make buildings more thermally efficient and sustainable. The Climate Change Act, commits the UK government to reducing carbon emissions by 20% compared to 1990 levels in 2020 and by 80% in 2050; targets that it will not be possible to achieve without a dramatic improvement in the energy efficiency of the existing building stock.
However, retrofitting involves the careful balancing of different elements and their effects on the overall performance of a building. A change in one part of a building can affect another, and sometimes this is only apparent after irreversible defects have occurred. It is very important therefore that risks are understood and managed in a way that is appropriate to each individual project. Standard solutions should not simply be rolled out without proper consideration, and it is vital that care is taken to ensure high quality installation.
As projects increase in size, the scope for client-side risks such as poor quality, poor supply chain coordination, and project overspend, also increase. A retrofit coordinator can be useful in this regard, taking responsibility for overseeing and managing the retrofitting of a building or series of buildings, typically providing effective management and leadership for large-scale retrofit programmes.
A retrofit coordinator might:
- Provide project management and client assistance from the start to finish with regard to planning, organising and managing the project.
- Provide consultants and contractors with informed advice and support.
- Provide clients with assurance that project risks are being effectively managed and quality is being maintained.
- Identify and provide solutions for possible risks to the retrofit process.
- Undertake post-occupancy evaluation to determine overall success and ensure that lessons are learned for future projects
Professionals from a range of backgrounds can become retrofit coordinators, including; architects, asset managers, building services engineers, building surveyors, construction managers, energy assessors and consultants, site foremen and so on.
The Royal Institute Of British Architects (RIBA) has recognised The Retrofit Academy CIC's eight-day training programme and the Centre of Refurbishment Excellence (CoRE) ten-day training programme to upskill existing professionals to become retrofit coordinators.
