Factors Affecting Orientation of Building
The following factors affect the orientation of a building
1- Sun Path
The orientation of building should be fixed in such a way that the sunlight should enter all parts of the building through doors, windows, and ventilators. Various germs take birth in those rooms where sunlight does not enter. These germs become the cause of various diseases.
2- The direction of Road/Street
Orientation is also much affected by the direction of the road or street. If some plot is situated between two paths, then the front view of the building should be to the side of the major path.
Surroundings should also be considered in the orientation of the building. It also includes the method of their construction, ways of living of the neighbours.
4- Wind Direction
The direction of wind blowing throughout the year should also be kept in mind. Favourable and unfavourable winds should also be taken into account.
5- Nature of Rainfall
Humidity affects a building very much. Therefore, the direction of rainfall should be assessed. So, in the building orientation, it should be kept in mind that the smaller part of the building should be affected as far as possible.
