|This project looked at designing a supply chain solution to improve the energy efficiency of the vast majority of the 26 million UK homes which will still be in use by 2050.It looked to identify ways in which the refurbishment and retrofitting of existing residential properties can be accelerated by industrialising the processes of design, supply and implementation, while stimulating demand from householders by exploiting additional opportunities that come with extensive building refurbishment.The project developed a top-to-bottom process, using a method of analysing the most cost-effective package of measures suitable for a particular property, through to how these will be installed with the minimum disruption to the householder. This includes identifying the skills required of the people on the ground as well as the optimum material distribution networks to supply them with exactly what is required and when.
This is the Executive Summary, which summarises the findings of WP4 D5, The Detailed Supply Chain Workshop. The full report is also available. This deliverable presents detailed plans for the delivery of mass scale whole house retrofit, covering the survey and installation process, the cost of retrofitting the most common property types in the UK and how the cost is built up - the design of an end to end supply chain model and specification
n prior work package 4 reports, an analysis and review of the retrofit supply chain was carried out and alternative supply chain models were reviewed. This led to the development of a ‘least wasteful supply chain model’. This seeks to overcome the inefficiencies of the current siloed trade based supply chain. The work described in this report has built on this model to include estimates of the likely regional demand and supply chain capacity needed to deliver manpower and materials to satisfy projected demand for retrofit.
