Sustainable metropolises——Why and how | Zhongqi Peng

Sustainability Challenges in Metropolises - Glass skyscrapers consume 40% more energy compared to non-glass buildings [1] - Metropolises face environmental challenges, including the heat island effect, where temperatures can be 5 degrees Celsius higher than in suburbs [2][3] - Traditional glass buildings exacerbate the heat island effect due to excessive AC usage and hot exhaust [3] The Three Pillars of Sustainability - Sustainable development requires a balance between environmental protection, social equity, and economic profitability [4] - Achieving a balance between these three elements is challenging [5] Case Study: Clark Key, Singapore - Clark Key was redeveloped with a holistic sustainability goal after a period of decline [6] - Transparent artificial canopies made from ETFE membrane provide shade and enable natural ventilation [7] - Rotating fans and a central fountain pump cooling water, creating a pleasant open space [8] - Clark Key's redevelopment was a success, attracting numerous tourists and locals [8] Solutions and Future Directions - New designs, technologies, and materials are emerging to promote sustainability [9] - Individuals should adjust their lifestyles and attitudes, such as slightly adjusting AC temperatures [9] - It is possible for metropolises to create economic systems that support long-term growth while emphasizing justice, social equity, and the well-being of communities [10] - Achieving the three pillars of sustainability requires intelligence, perseverance, and determination [11]
