Reduction of energy consumption is a high priority in today’s society. This is also true for countries like Vietnam, where nearly 75% of the population are directly affected in some way by climate change. The local population deals with long and intense summers each year. Urban areas in particular feel a large impact, due to the heat island effect, where temperatures are significantly higher than in the surrounding areas. As a result, there is an increasing demand for electricity to cool down buildings. In the future, this could pose a challenge to their current power supply network and the financial availability of electricity.
To counteract this, passive cooling of buildings and adaptations to reduce heat stress can be applied. This project will mainly focus on the implementation of green roofs & reflective roofs in the suburbs of Hà Nội and Hà Tĩnh. In Cooperation with the Hà Nội University of Civil Engineering and KUL, these sustainable rooftops will be implemented on 25 Vietnamese houses as a case study, to use as a reference for wide scale implementation in neighborhoods spread across Vietnam.
In preparation for this project, modeling software will be implemented to prove the cooling efficiency. The tests will be simulated on the scale of a single building, after which further simulations will be made to study the impact on the entire neighborhood.
