Building characteristics as determinants of propensity to high indoor summer temperatures in London dwellings

► We model 3456 dwelling variants that represent the London stock. ► We examine the levels of indoor overheating under the current and future climate. ► There is appreciable variation between dwelling types but larger variation within dwelling type. ► Combined insulation measures appear to decrease internal temperatures. ► Internal solid wall insulation may increase overheating if no night time ventilation is provided.
