This thesis explores the impact of vegetation application to building envelopes – specifically, green
roofs and green façade—on building thermal load and urban heat island effect within the context of
Ho Chi Minh City, Vietnam. Two case study buildings in densely populated, Phu Nhuan District,
are the focus of this thesis. This study demonstrates that green roofs and green façades can decrease
building thermal load by impacting cooling load with building thermal load calculations. However,
factors such as building design, vegetation scale, and solar radiation intensity affect the
effectiveness of these green applications.
In addition to building thermal load calculations, this thesis investigates the wider potential of green
roofs and green facades in mitigating the urban heat island effect in rapidly urbanizing cities, such
as Ho Chi Minh City. The results of urban weather generation suggest that while green roofs and
green façades can reduce urban temperatures, small-scale applications are insufficient for
comprehensive UHI mitigation.
By offering empirical data, this thesis contributes and highlights the importance sustainable urban
planning. It emphasizes the critical role of building-specific vegetation applications in improving
building energy efficiency, managing urban heat island effect and enhancing envrionemental
sustainabiliy in rapidly urbanizing cities.
