Abstract: Thailand committed to achieving the Sustainable Development Goals to increase urban livability and reduce energy use in the building sector. However, the design information to achieve those challenge goals has been undefined. This study aimed to investigate and examine potential improvements for outdoor thermal comfort and energy efficiency in 136 designs of the two-type residential cluster in Pathum Thani, Thailand, via designs of building orientation, geometry and window-to-wall ratio (WWR). The daily cooling energy consumption in residential clusters was performed using eQuest under the modified weather data from the prior microclimate analysis. The energy-saving scenarios were calculated and compared to the acceptable outdoor thermal comfort hours. It is found that the row house cluster had the potential to be more sustainable than a single house. The row house clusters on orthogonal street orientation offered the highest percentage of hours in outdoor thermal comfort of 46% and energy efficiency below the new standard of Thailand. The cooling energy savings through increasing H/W with lowering WWR was up to 32%. This study’s results could provide urban planners and architects with the new design guidelines and improvement potentials to make cities more energy efficient and environmentally friendly for outdoor living in Thailand.
