About the speaker

Dr. Dang Thanh Hung held his bachelor’s degree from UAH in 2007. Then, he gained his master’s degree in environmental design from the University of Nottingham, UK in 2012. From 2015, he was a Newton Fund scholar and a postgraduate researcher (Sustainable Architecture and Built Environment) at the University of Huddersfield, UK. He was awarded the Doctor of Philosophy in 2020. 

He has worked in all three fields: education/training, research, and practice. His research and practical interests include public and residential buildings; human comfort, adaptation, and behaviours; environmental design; energy-efficient buildings; passive design; sustainable buildings and cities; design practice and guidelines; vernacular/heritage architecture; urban planning and climate change.

Paper Abstract

Understanding the Interplay of Urban Morphology and Environmental Conditions in Settlements in Ho Chi Minh City, Vietnam

The urban historical development of Ho Chi Minh City has reported the parallel existence of planned and spontaneous districts, even the integration or juxtaposition of both regular and irregular planned settlements found within a ward. The city expansion has been attached to the growth of the economy, population, and urbanisation. As a result, many urban blocks are characterised by distinctive spatial structures and constitutions. Sequentially, the urban climate is changing and performs variations at both the macro and micro scales, significantly affecting the human living environment. So, people’s tolerance, behaviours, and adaptation have also been adjusted to restore their comfort. The paper understood the characteristics of residential neighbourhoods in terms of their urban morphology and environmental performance. Furthermore, the study deciphered the interplay between the two features and advised on how to improve the outdoor microclimate, which is beneficial for outdoor comfort for pedestrians and a better indoor environmental condition linked through exchange between two environments. Over 60 settlements classified into seven urban types were visited and measured with environmental indices in cool and hot seasons. Outdoor climatic conditions were more pleasant in cool months. However, the onsite measurements concluded discomfort for people due to high temperatures and low winds in all seven urban types. The external microclimate was more satisfactory in neighbourhoods, which featured a regular pattern, low density, and available plants and green spaces, especially in pericentral areas. Meanwhile, the environment around unplanned settlements was difficult to predict.
