Abstract: This paper introduces a methodology aiming to characterize individual indoor exposure for health risk assessment related to overheating, using building energy simulation (BES). Heat stress in BES is currently assessed by stationary indicators, whereas nonstationary thermoregulation models are more appropriate for prolonged exposure. On this basis, this contribution suggests a new set of indicators suited for heat stress analysis on two timescales. To test the methodology, current BES is carried out for different types of urban dwellings and cooling strategies. Results highlight effects of dwelling type and urban climate on the strategy’s efficiency regarding health indicators and limits of current models.
