The floor-plate strategy is about the relationship of the building’s floor plate shape, its position on the site, and its orientation to the sun’s path and wind direction. In hot arid and tropical climates, the optimum shape is a rectangle that minimizes the length of east and west sides, while maximizes that of north and south sides, to reduce solar insolation on wider sides. The internal spaces arrangement should be planned to reduce solar gain into high occupancy spaces, while service spaces can be used as solar buffers.
Building Skin Design
A well-designed building envelope will yield significant energy savings. Its permeability to light, heat, and air and its visual transparency must be controlled with flexibility of modification, so that the building can react to changing local climatic conditions. The ideal envelope is the one that is environmentally responsive filter. The green approach does not recommend using hermetically sealed skins. The building skin has to be multi-functional: reduces solar heat gain to the internal space through external shading, maximizes the use of daylighting, provides fresh air ventilation, serves as acoustic barrier, and contributes to the building’s esthetics. Double skin fa?ades can provide several benefits: solar control, noise reduction, high-wind reduction, natural ventilation.
