Orientation of BuildingOrientation of building is to design building in such a way as it receives maximum ventilation andnatural light in all climatic conditions. It provides comfortable living conditions inside thehouse/building and saves energy bills also. The orientation can defend undesirable effects of worseweather. While planning to build a new house, ask your architect to design building in such a way thatenergy loss is minimum.

Climatic ImplicationOrientation of building determines the amount ofradiation the building receives. The orientation withrespect to air patterns affects the amount of naturalventilation as much as possible.

Benefits of buildingorientationEnergy saving

Orientation of building is energy efficient approach as the building orientation saves heating, coolingand lighting cost. You can take optimal benefits of the sun by maximizing southern exposure. It lowerscooling cost by minimizing western exposure where it is most difficult to provide sunshade.

Breeze/Natural AirOrientation of building provides breeze is in warm and humid climates. On the other hand, theorientation prevents hot winds in hot and dry climates.

Natural ventilationBuilding orientation provides natural ventilation and light which is beneficial to the health of inhabitantsof the house.

Factors Affecting Building Orientation1. Solar radiation and temperatureThe intensity of solar radiation depends on the direction of sunrays. The temperature of a structureand living space increases due to sun radiation and affects environment of the house. Solar radiation

acts in two ways. Sunrays directly come to the house through openingsRadiation comes indirectly through walls and roof of building by absorbing heat.

For comfortable living particularly during summer season, radiation, temperature and treatment ofroom are considered. From solar radiation point of view, the best orientation is that which receivesmaximum solar radiation during winter and receives minimum solar radiation during summer season.

The South façade has advantage of receiving more solar radiation during winter than that ofreceiving during summer. Even for openings on south facade, small overhang such as curtains can cutoff direct solar penetration during summer and allows it during winter. Obviously, this is most beneficialaspect, not available on any other façade.

How to minimize solar heat insouth façade?In fact the incidence of ground reflected radiation onhuman body from southern sun in south facadecauses great thermal discomfort and visual glare. Innorthern India the South wall of a building or housereceives least solar radiation during summer. Tominimize reflected solar heat, grassy lawns should bedeveloped in front of south façade.

How to minimize solar radiationin western façade?

The eastern and western façade receive nearly equal amounts of daily solar radiation throughout theyear. The only difference is when the sun shines on eastern façade, the building or house iscomparatively cool and air temperature is low. On the other hand due to higher air temperature inafternoon, the heat flows indoor through western façade. To minimize the affect of solar radiation inwestern façade, the sunshade on openings should be constructed.

2. Clouds and RainsClouds and rains have comparatively less importance in orientation of building. The areas with lowclouds cover sky largely and determine the effect of both incoming solar radiation and outgoingterrestrial radiation. Glazing and opening should be designed keeping in view the direction of rain,beating the building because the direction of rain is generally same as that of prevailing wind expect incase of storms. If due to architectural view glazing is provided, it should be covered by propersunshade etc. The walls of lesser thickness should not be designed in the direction of heavy rains.

3. HumidityIt depends on weather condition of the area and has little role in orientation of building. The movementof air and use of prevailing wind are very important during periods of high humidity. Humidity can be

classified into four categories i.e.

Very dryDryHumidVery humid

When humidity is low, dry or very dry, it is easy to take advantage of evaporative cooling in summer.When it is humid or very humid it is desirable to regulate the rate of air movement either artificially withaid of electric fan or with help of prevailing winds.

4. Humidity design considerationThe comfort in relation to humidity becomes complex. In humid environment there is very warm feelingwhen there is no breeze and air temperature is 30 0C. On the other hand if humidity is low, one mayfeel cool even if the temperature rises up to 32 0C with little breeze. It will be cooler at the sametemperature if there is reduction in relative humidity. And if there is breeze in high humidity area, thebuilding should be designed in such a way as it has more natural air and ventilation.

5. Prevailing windsPrevailing winds help create natural ventilation in a building and give more comfort during highhumidity. During orientation of a building and designing doors and windows openings, the direction ofwind flow should be considered. Fix windows and ventilators at proper location in building to providemaximum air and light. The height of windows has much concern about ventilation. Maximum air andventilation can be obtained if the level of opening is at the level of occupancy.

Consider velocity and direction of wind fororientationFor the purpose of orientation, it is necessary to study velocity and direction of the wind at particularplace throughout the year. It is better if the flow of wind is more in building during humid period thanrest period of the year.

Close openings to avoid heat and glare insummerOne should take appropriate action during orientation of building so that the building providesmaximum comfort. Where there is extreme heat in summer and it becomes necessary to closeopenings to avoid heat and glare, it would be helpful to orient buildings to face winds during humidmonths instead of facing prevailing wind which comes from some other direction.

Note: Ideal or desirable orientation may not be possible in each individual case due to various factorsin every situation. In this age of advance technology in materials and mechanical aids, the lighting andventilation can be obtained for living and working after deciding on orientation of building.
