Ele mostra por exemplo como as torres de serviços com elevadores, escadas e sanitários podem se tornar proteções solares para os edifícios. Normalmente instalados no centro do edifício precisam de ventilação mecânica e gastam assim mais energia do que se fossem ventilados naturalmente. Ken Yeang sugere para países tropicais que essa torre seja dividida em duas e estejam colocadas nas fachadas leste e oeste, assim protegem o edifício das radiações mais críticas e a torre de serviços e ventilada naturalmente. Vale a pena dar uma conferida no site: http://www.ellipsis.com/yeang/index.html#top
Although bioclimatic principles are relatively well advanced for low- and medium-rise buildings, there has yet to be adequate attention and research directed at tall buildings. Justifications for greater attention are obvious. Traditional building types cannot suffice as design models for the high-rise since the scale and bulk of the high-rise far exceed any precedent. The tall building being largely a novel (i.e. non-traditional) building type, with new servicing systems, it requires its own set of design premises even though the fundamental principles of designing with climate remain unchanged.
In Bioclimatic Skyscrapers service core position is of central importance in the design of the tall building. The service core not only has structural ramifications, it also affects the thermal performance of the building and its views, and it determines which parts of the peripheral walls will become openings and which parts will comprise external walls. Core positions can be classified into three types: central core, double core and single core. In the tropics, cores should preferably be located on the hot east and west of the building. A double core has many benefits. With both cores on the hot sides, they provide buffer zones, insulating internal spaces. Studies have shown that minimum air-conditioning loads result from using the double-core configuration in which the window openings run north and south, and the cores are placed on the east and west sides. The same considerations apply in temperate zones.
