Architectural Planning
1. The natural environment is at once hindrance and a help, and the architect seeks both to invite its aid and to repel its attacks. To make building habitable and comfortable, one must control the effects of heat, cold, light, air, moisture, and dryness and foresee destructive potentialities such as fire, earthquake, flood, and disease. The placement and form of buildings in relation to their sites, the distribution of spaces within buildings, and other planning devices discussed below are fundamental elements in the aesthetics of architecture.
2. The arrangement of the axes of buildings and their parts is a device for regulating the effects of sun, wind, and rainfall. Within buildings, the axis and placement of each space determine the amount of sun it receives. Orientation may control air for circulation and reduce the disadvantages of wind, rain, and snow. The characteristics of the immediate environment also influence orientation: trees, land formation, and other buildings create shade and reduce or intensify wind, while bodies of water produce moisture and reflect the sun.
3. The choice of materials is conditioned by their own ability to withstand the environment as well as by properties that make them useful to human being. One of the architect's jobs is to find a successful solution to both conditions; to balance the physical and economic advantages of wood against the possibility of fire, termites, and mold, the weather resistance of glass and light metals against their high thermal conductivity, and many similar conflicts.
4. The control of the environment through the design of the plan and the outer shell of a building cannot be complete since extremes of heat and cold, light, and sounds penetrate into the interior, where they can be further modified by the planning of spaces and by conditioning devices. Today, heating, insulation, air conditioning, lighting, and acoustical methods have become basic parts of the architectural program.
