Our Existing Homes are Becoming Obsolete: A Retrofit Case Study of Crescent House Part 2 Dissertation 2024 Nimra Shahid Kingston University Kingston | UK 75% of all housing in the UK was created before 1980 (BRE Trust, 2020, pp.16), a lot can be done to address climate change, and achieve net-zero through the retrofitting of our existing homes.The research is a case study of The City of London’s Grade II* Crescent House of the Golden Lane Estate. It discusses the importance of a comfortable Indoor Environmental Quality (IEQ) with a focus on thermal comfort, condensation and dampness in the winter months. It looks at a retrofit programme for Crescent House, utlising quantitative data from surveys, and qualitative data from interviews to see how a good IEQ is achieved, whilst making the building energy efficient. Later, the research highlights a few lessons for any retrofit programme. Results show that 55% of Crescent House flats lose winter heat through the building fabric, with 83% suffering from condensation and mould issues. Flat A, and Flat B residents were chosen to provide further insight into IEQ satisfaction. Retrofit requires a collaboration between all stakeholders, and a thorough understanding of the building fabric and its issues. This leads to tailored solutions, whilst making the building energy efficient, achieving resident satisfaction with IEQ, and in parallel addressing climate change. Tutor(s) Heba Elsharkawy
