||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 deliverable is number 2 of 7 in Work Package 2.
- It presents the initial approach to the costing methodology for thermal efficiency improvements to be employed by the project and incorporated into the computer model being developed.
- Accurate cost information for retrofit interventions is key to ensuring the identification and development of the optimum solutions for each housing archetype previously identified in deliverable D2.1.
- Costs of two types are considered:
- Unit costs
- Other fixed costs
- Costs are input for:
- Loft insulation
- Cavity wall insulation
- Hot water tank insulation
- Floor insulation
- Replacement windows
