The heat island effect in Taichung City is becoming increasingly severe due to rapid economic development and urbanization. Mayor Lu officially announced at the "Taichung City Carbon Reduction and Cooling Forum" in 2020 that the Taichung City Government will use three cooling miracle drugs, "wind inducing, green increasing, and blue retaining." These measures involve increasing urban wind corridors and water areas to attract wind, enhancing urban green coverage, and actively improving air quality. The government aims to mitigate urban heat radiation and slow down the progression of the heat island effect.

This plan aligns with the aforementioned important policy directions, such as the core indicators of Sustainable Development Goal 11 (SDGs-11) on sustainable cities and communities, and SDG-13 on climate action, as outlined by the United Nations the United Nations. It also adheres to the guidance provided by the "Taichung Land Plan" for Climate Change Adaptation Planning. By diagnosing and analyzing the environmental changes of the heat island effect in urban development, collecting relevant research literature and domestic and foreign cases, and taking stock of appropriate policies, plans, laws, and other applicable tools and resources, it proposes countermeasures, action plans, and implementing agencies for areas with severe hotspots in the city, besides clearly grasping the distribution and intensity of hotspots. Moreover, the project has established strategies such as green water cooling and urban cold spot strategy retention, natural and urban wind corridor construction, and ventilation control. And it has identified areas with severe urban heat island effects such as high temperature, low wind speed, and high heat pressure that urgently need improvement as "key heat island areas" for 3D environmental microclimate analysis of urban heat islands. Grasp the improvement benefits of wind corridors, water, green systems, and solar shading as a reference for subsequent amendments to urban planning laws and regulations to create a more livable living environment in Taichung.
