Needs

To design a building, architects should consider very important things, like the needs of the people who will use that building, the environment where the building will be, and the structural needs, while keeping harmony between these aspects. Also, he or she needs to consider that all of these elements may change. They have to cover needs of the people, as physiological (light, oxigen, water, heat, waste, CO2), psychological (sense of safety and security) and sociological (interaction with others); structural needs, as protection (to the buillding and occupants), weight (must resist natural disasters and support its own weight), comfort (appropiate lighting, good air temperature, comfortable humidity, and adequate circulation), flow (optimum entrances and exits), distribution (energy, information and various materials); and needs related with the context as culture (historical, religious and political), environment (have to be related with it), connections (electrical power sources, telephone lines, sewer systems, transportation), economic (feasible with changing needs), flexible (change with changing needs).
