Assessment of climate change on UK dwelling indoor comfort

The future weather file for 2080 with 90th percentile data show a large increase in overheating events and is considered too extreme. The need for active cooling in bedrooms is expected to occur around 2035 and is independent of a heat wave. Results for living rooms are more variable with thermal mass mitigating the adoption of active cooling by 40 years and 25% of the overheating in a heat wave event. Designers need to think about thermal mass usage in living rooms to cater for extreme temperature events rather than the whole of the cooling season to delay the adoption of active cooling.
