The effect of building design in reducing consumption

Since we live in hot environments, the design of buildings has an important role in reducing the temperature inside, and this has a direct impact on reducing the consumption of electrical appliances. This can be done through adaptation and lighting, reducing the size of the appliance, or by reducing the size of the building itself. The design of the building must take into account the natural conditions in which it will be situated, as well as the use of natural lighting and ventilation. We discuss several different ways that can help improve the climate inside a building under design.

The general shape of the building and its orientations

The ideal general shape of the building is the one that enables it to receive the least amount of sunlight, and therefore the rectangular shape is the ideal shape of the building so that it is the longitudinal side facing the building.

Windows Design

Window design is an important part of a building’s design, and should be considered in terms of both aesthetics and functionality. By reducing the amount of flat surface on the windows, the architect can create a more pleasing appearance while still allowing light and air into the building. Additionally, engineering forms can be designed to function as blinds, decreasing the amount of sunlight entering the building. The design must be made of double-glazed windows to help reduce heat leakage inside the building.


The appropriate afforestation gives comfort and reduces costs. Therefore on the southern side of the building it is preferred to plant trees with falling leaves in the winter, and that is to provide a shade from the sun’s rays in summer but in the north, western and eastern sides it is preferred to grow trees that are green all year long to prevent the sun rays from entering the house in the summer, and to serve as a windbreak in the winter, limiting the strength of the wind.

Use light colors

Light colors have the property of reflecting rays, whether it is sunlight or indoor lighting, therefore, it is preferable that the paints for the external walls, or the marble or stone used, be of a light type. In order to reflect the sun’s rays and reduce its absorption of heat and its leakage inside the building, which means reducing the consumption of air conditioning, and thus saving in consumption. This is to reflect the sun’s rays, reduce its absorption of heat, and leak it inside the building, which means a reduction in air conditioning consumption, and thus savings in consumption. It is preferable that internal paint are of the light type, so that the minimum limit can be used from lighting devices, and therefore reduces the effect of the lighting warm within the buildings, which leads to the arrival of the accommodation of the accommodation and the clock.

Raising the level of comfort

The composition of thermal isolation in the buildings helps to raise the level of comfort due to the stability of the heat levels all year within the building, and it is that the thermal isolation makes the air within the building tolerated without air conditioning, As the thermal insulation materials limit heat leakage into the building. And the internal air temperature is relatively close to the comfortable temperature for humans, which ranges from 25 to 27 degrees, which alleviates the suffering of the building user from the tension of the external heat. It reduces the operating times of air conditioners, In contrast to an uninsulated building, Where the temperature of the air inside is close to the level of the outside, Which makes the difference between them and the required comfortable degree so great that there is no feeling of comfort, and therefore the urgent need to run the air conditioners for long periods, to reach this comfortable degree.
