SUMMARY
The traditional image of the invidual high-rise tower isolated from the urban context and neighbouring buildings is being challenged today by architects who recognize the potential of the multi-functional building type to mediate between functional and aesthetic singularity of the modern tall building and the need to accommodate its functions and scale to the life of the street and the humanizing condition of public space. The use of construction systems with different spans is determined by the vertical and horizontal zoning of functions, energy savings and microclimate are based in particular on the utilization of passive systems and the absorbed sun energy. Each of the buildings will be characterized by its bio climatic principle.
