Urbanisation and the warming up of these urban areas are important phenomena in a world characterised by a strong growth in population and an elevating standard of living. More people live in cities and the temperature in those cities is increasing. Therefore, it’s becoming more important to know which kinds of neighbourhoods are the most comfortable to live in and how to build cities that are better adapted to the climate. Heat-stress is a consequence of a hot and humid climate that has a bad influence on the health of the citizens. Vegetation (green structures) and water (blue structures) can play an important role in the sustainable and comfortable city of the future. The difference in average night temperature of September between suburbs with and without green structures is 0.6°C. For that reason, this research investigates the impact of city design on the thermal comfort in Ha Tinh, Vietnam. The different neighbourhoods, with different zones in a city based on built form and land coverage, are compared to each other in terms of temperature, relative humidity and thermal comfort. The neighbourhoods with the highest temperatures and the highest levels of heat-stress are those located in the city centre, with low, compact rise, followed by the open rise built-up areas without much vegetation. The local climate is the most comfortable when the temperature and the discomfort index are at their lowest, i.e. in the neighbourhoods with more vegetation, the difference in average night temperature for September is 1.6°C between the city centre and the neighbourhoods with more vegetation. These neighbourhoods are the suburbs with open built-up area and scattered trees and the rice paddies. The areas around the water are less comfortable during night-time than the suburbs with less vegetation. The water buffers the temperature, so the temperature doesn’t decrease as much during the night and doesn’t increase as much during the day. During the cold season, fewer differences are observed between the neighbourhoods and zones of the city. These conclusions are all of great importance to city designers. The suburbs with trees have higher thermal comfort, which implies the importance of vegetation in the streets. When building new city areas, it’s important to be smart and keep your eye on the comfort of the people who live in it.
