The past two decades have witnessed concerns caused due to the global increase in surface temperatures. With the world exposed to a quickly changing climate, exposure to and impacts of events like heat waves, floods and droughts has become a concern. While this is happening outside an individual’s dwelling, the impacts on indoor thermal comfort are significant. Maintaining comfort inside while the weather outside changes unexpectedly is the challenge for contemporary design. This study for the city of Roorkee, India tries to address this issue by identifying a trend in the daily maximum air temperature (Tmax), daily minimum air temperature (Tmin) and daily mean air temperature (Tmean) values recorded from 1976-2016. Representative weather files for each decade have been created and selected residential buildings built in the last 10-20 years have been simulated using Design Builder against these representative weather files to analyse number of comfort hours on the tropical summer index. Using the analysis, several passive design strategies have been simulated and the best passive-design solutions have been proposed for composite climate of India. Validation of simulated data has not been considered for the currrent research context.
