Investment Grade Proposals for Portfolio Retrofit

City Science will develop and test a first of it's kind tool for providing "Investment Grade Proposals for Portfolio Retrofit". The core idea behind this tool is to help break down some of the key barriers to scalable retrofit and accelerate the decarbonisation of the UK building stock. Key barriers, as recorded by the Green Finance Institute include: * The lack of certainty in the benefits of retrofit measures * A lack of incentives to incur the high upfront costs Our proposed tool addresses these barriers by: * Utilising a highly evidenced, data driven approach to provide the required certainty around the benefits of retrofit measures. * Unlocking access to finance by providing certainty around financial, environmental, and social return on investment. * Providing solutions which best satisfy the needs of all parties In phase 1 of this competition we developed and tested the technical and commercial feasibility of our proposal as well as it user acceptability. Within phase 2 we will test our solution in a real-world environment through collaboration with large portfolio owners and managers, as well as the supply chain.
