Abstract: This study is the first step to evaluate the effectiveness of ENVI-Met simulation models for further research on improvement of outdoor thermal condition of neighbourhood typologies in the city of Ha Tinh, Viet Nam. In this research, the rural ward of Thach Dai that represents a sub-urban neighbourhood typology was the case study where ENVI-Met simulations of outdoor thermal condition for typical days of summer 2020 and on-site measurements for model validation were performed. The measurement results indicate different thermal condition at various measurement locations, most probably caused by deviated morphologies. High leaf area density plants and water bodies are key elements to provide thermal comfort. The simulation results show the usefulness of ENVI-Met in the study of microclimate in Ha Tinh, and is a suitable tool for further analysis and validation of development of future neighbourhood typologies to provide better outdoor thermal comfort.
