Orientation of Building

• The orientation or arrangement of the axis of a building is a way of controlling the effects of the sun , wind and rain since the sun is regular in its path & favours the southern aspects of buildings in the nothern hemisphere .
• The building may be orientated to capture the heat of the sun or else it may be turned to avoid the solar heat in the tropics .
•  Orientation may also be used to control air flow circulation & reduce the disadvantages of wind , rain and snow when existing currents are predictable .
• The character of the local terrain may have some influence on the final orientation of the building by the way in which rolling groud , trees & adjacent buildings create shade & reduce or intensify the effects of the wind .
