如城市里街道和人行道的坚硬表面一样,城市建筑物的水平或垂直表面也造成了世界范围内大城市气温的不断上升。但是,人们并没有采取任何改善措施,而是把建筑物立面看作为室内人员提供舒适环境的结构,并忽略其对室外产生的影响,或是把它当做其所有者可识别美感的象征。本文提出了将建筑物立面作为“户外行人福利管家”的反思,以及将公共健康作为建筑物立面附加功能的概念,该概念强调要考虑户外行人的利益和健康。如果把一个城市建筑物的全部表面积看做是城市基础设施的一部分,那么它的作用不仅是使室外的空间更加舒适、卫生、宜人,还要有助于缓解城市气温上升这一更大的问题。 Like the hard surfaces of streets and sidewalks in cities, the horizontal or vertical surfaces of urban buildings have also led to rising temperatures in metropolitan cities around the world. However, no improvement measures have been taken. Instead, the facade of a building is seen as a structure for indoor personnel to provide a comfortable environment, ignoring its impact on the outdoors or as a symbol of its owner’s recognizable beauty. This article proposes the concept of building facades as an “outdoor pedestrian welfare stewardship” and the concept of public health as an additional function of the façade, emphasizing the consideration of the interests and health of outdoor pedestrians. If you look at the total surface area of ​​an urban building as part of an urban infrastructure, its role is not only to make outdoor spaces more comfortable, hygienic, and pleasant, but to help alleviate the larger problem of rising urban temperatures .
