Abstract

The Intergovernmental Panel on Climate Change has predicted that the earth’s temperature is increasing by 1.5°. Research indicates that 9 out of 10 homes within the United Kingdom may experience overheating. The growing concern of overheating within residential homes should be resolved before occupants turn to the use of mechanical means. Passive cooling strategies need to be implemented into residential homes as a contribution to the current aim of the United Kingdom government to reduce carbon emission by 77% by 2035 compared to 1990 levels. This research investigates the most appropriate building construction fabric as a passive cooling strategy that can be implemented into residential homes to mitigate the impact of climate change. Computational fluid dynamic simulation of different building fabric scenarios of EcoBIM construction, Passivhaus construction and Standard construction are performed using EDSL Tas thermal modelling software. The simulations incorporate Chartered Institution of Building Services Engineering (CIBSE) weather data files for Glasgow, Belfast, Manchester, and London for 2020s, 2050s and 2080s climatic projections. The results from this investigation show that the standard construction overall did present the most effective solution against the number of hours experiencing overheating. The research provides evidence to suggest that the current 2021 Building Regulations in place are not at risk of experiencing overheating in Manchester, Belfast, and Glasgow across the 2020, 2050 and 2080 simulations, as well as for the 2020 and 2050 London simulation. This proposes that within these locations the current 2021 Building Regulations regarding the U values in document Part-L shall be deemed as having an acceptable tolerance to overheating, and further adaptations are not necessary, as there is no concern regarding the encountering of overheating within these regions and weather periods. Furthermore, the utilization of the EcoBIM construction on average did cause significant increased risk of overheating. The only exception to this was the 2080 simulation for London in which the EcoBIM construction obtained 71.10% less overheating compared to the Standard construction. The outcome of this research suggests that London is at extreme risk of enduring overheating by 2080, as all the constructions during this simulation process were perceived as exceeding the CIBSE TM59 requirement.
