Abstract: In response to global climate change, there is a strong urge for regulating the thermal performance and associated energy use in buildings. Typically, building performance assessments are carried out considering the influence of macro- environmental characteristics. However, micro-environmental variables also modulate the convective and radiative thermodynamic exchanges significantly. This study aims to analyse the impact of location-specific urban developments on the ventilation availability and in turn the thermal and comfort performance. For this purpose, a residential building located in Thiruvananthapuram, India (8.5N; 76.9E), is considered. The city represents a warm humid climate. The residential building under consideration is predominantly operated in a free-running mode. Thermal performance and comfort assessment of the building were carried out using Energy Plus tool. The paper presents two different scenarios – (1) Assessment carried out using standard weather data of the city and (2) Assessment carried out using the micro-climate data. The micro-climate data for the building location are obtained from a detailed micro climate model developed using the Cradle-SC Stream simulation tool. The study compares the variations in ventilation availability and its resulting impact on building thermal performance and comfort.
