Buildings Orientation and its Impact on the Energy Consumption
Nowadays, many countries suffer from severe shortage of energy resources and the
inability of saving it. It is necessary to develop an integrated strategy, to make buildings
consume less energy and to integrate active and passive design techniques.
Since the building orientation is one of the most important factors affecting energy
consumption, this paper addresses the effect of building orientation on the amount of
energy consumption within buildings. We employ the simulator "Energy-plus" to estimate energy consumption annually and during critical months in summer and winter.
To obtain the best orientation for maximum energy saving, different orientations are
tested. It is found that an air-conditioned building that has a southern facade consumes
less energy. However, a western facade causes higher annual energy consumption by
26% over the southern facade. In the case of a two-facade building, the lowest energy
consumption is obtained between the northern and southern orientations in Cairo, Egypt.
