Abstract

Tall buildings have always been built as totem: in fact, the skyscrapers acted a central role in the city of the early twentieth century and therefore they had to be fully recognizable from all the parts of the city. Their role changed along the last decades becoming in some cities of the world the only viable solution to face the growing price of the land. Skyscrapers are now spread almost everywhere and they are integrating a number of functions at the same time: offices, residences, hotels and public spaces; according to some studies, they seem to be one of the challenges for the sustainable city of the next century. In order to achieve this goal some mistakes have to be avoided. Today’s skyscrapers are built as mere glass-boxes where the internal environment is only controlled by air conditioning. Often, they seem to be built without taking into account the constraints given by the setting: sunlight, wind, solar radiation, surroundings (other buildings, views, etc). Moreover, the needs of the users differ according to the purpose of their presence within the building: offices, hotels, residential floors or touristy places are placed one over the other “wrapped” within the same enclosure. Each typology of user requires very particular characteristic by the places he is living in: i.e. the need of light of a worker doesn’t match with the light requirement of a person sleeping one story higher; also, the façade facing South doesn’t have the same stressors than the one facing North, and so on. The actual way of producing building’s enclosures creates discomforts in the users and increase the energy requirements of an high rise building. This paper analyze the opportunities given by architecture and building technology to characterize the enclosure of a skyscraper in order to improve its performances and meet the requirements of sustainability needed by our culture. An example of regional setting of a skyscraper is provided.
