Abstract: Accurate urban climate modelling is challenging given its geometrical and physical interaction complexity, although such modelling is paramount in the discovery of sustainable solutions. Cities will undergo significant changes in local climate as the urban heat island effects will be compounded by climate change. Towards equipping stakeholders with tools and solutions to face these changes, we have developed an urban climate modelling suite that can capture most local urban physics. We demonstrate the capacity of this computational framework to consider different mitigation solutions and their impacts on local urban environments undergoing a heat wave. We show how urban solutions deal with an intricate system of heat and mass exchanges, where true contributions require careful assessment of the urban climate.
Keywords: Urban local climate, all physics modeling, mitigation solutions
