Abstract

Due to the increasing urgency of climate change and the need for sustainable growth, governments worldwide, including the UK, are being pushed to implement rigorous energy efficiency standards in building maintenance and construction. Cavity wall insulation, or CWI, has gained a lot of attention in this context as a workable solution to lower energy expenses and improve thermal comfort in residential structures. Thus, this research explores how Cavity Wall Insulation (CWI) can improve energy efficiency and lower carbon emissions in buildings in the United Kingdom. It places special attention on how this technology might be applied to future housing and how it can help meet national climate change targets. It thoroughly assesses the thermal performance, economic viability, and environmental effects of a range of insulation materials, such as mineral wool, aerogel, expanded polystyrene (EPS), polyisocyanurate (PIR), and environmentally acceptable substitutes. Utilizing modern simulation tools such as TAS Manager, the research models numerous insulation situations, taking consideration of complicated variables such developing weather patterns, building geometry, and occupancy behaviours. Important technical issues are brought to light by the investigation, including moisture intrusion, thermal bridging, and the deterioration of insulating materials over time. Depending on the kind of building and the climate, results show that using Minitab analysis to optimize material selection and insulation thickness can lead to improvements in thermal performance of up to 25%, energy cost reductions of 15-20%, and a decrease in carbon emissions of 10-12%. Thus, in terms of insulation for sustainable construction practices, this work concludes that 250 mm of mineral wool and 250 mm of sheep wool are the best options available. These materials are perfect for environmentally responsible projects since they have low embodied carbon, good thermal performance and are reasonably priced.
