Abstract

<p>In Asian megacities, not only climate change but also heat island phenomena are expected to pose air temperature increase. Therefore, effective adaptation measures to alleviate health damage caused by temperature increase are becoming more crucial. The objective of this study is to evaluate the effect of air conditioner on health damages using disability-adjusted life year（DALY）and considering an adverse effect from temperature increase accompanied by exhaust heating from outdoor units and uncertainty of the effect caused by interannual variability in temperature in Jakarta, Indonesia. Health damages to be assessed were sleep disturbance and fatigue. By increasing the usage rate of air conditioners, it was estimated that the DALY reduction per person per month in August of the average temperature year is 2.48 × 10^-4 years for sleep disturbance, 1.43 × 10^-5 years for fatigue, and totally 2.62 × 10^-4 years. It corresponded with 29.8% reduction from the present situation. The effect of interannual variability in temperature was not large, which was 7.94 × 10^-5 years at most. Air conditioner will be one of effective adaptations throughout the year considering small monthly variability in temperature and the residents’thermal perception.</p>
