Introduction
Orientation of the building generally used to refer to solar orientation which is the siting of building with respect to solar access. Although any building will have different orientations for its different sides, the orientation can refer to a particular room, or to the most important facade of the building.
The building orientation can have an impact on heating, lighting and cooling costs. By maximizing southern exposure, for example, one can take optimal advantage of the sun for daylight and passive solar heating. This will result in lower cooling costs by minimizing western exposures, where it's most difficult to provide shade from the sun.
Definition
Orientation strongly relates a building to the natural environment the sun, wind, weather patterns, topography, landscape, and views. Decisions made in site planning and building orientation will have impacts on the energy performance of the building over its entire life cycle.

Brief Description
Energy conservation strategies relating to building orientation are : --
Maximizing north and south face exposure for daylight harvesting to reduce lighting electrical loads
Using southern exposure for solar heat gain to reduce heating loads in the heating season
Using shading strategies to reduce cooling loads caused by solar gain on south face.
Shielding windows and openings from the direction of harsh winter winds and storms to reduce heating loads
Orienting the most populated building spaces toward north and south exposures to maximize daylighting and natural ventilation benefit.
The orientation of a building is influenced by numerous environmental and built factors, among them : --
Sensory
Psychological
Local development patterns
Other considerations
Sensory
Thermal solar exposure, wind direction, temperature
Visual varying daylight qualities in different locations and at different times of day
Acoustical direction of objectionable noises
Environmental smoke, dust, odors
Psychological
Views
Privacy
Street activity
Other considerations
Aesthetic
Direction of storms
Site conditions topography, geotechnical, wetlands
