Orientation Effect on Energy Consumption in Building Design

Energy consumption in a new building design project is nowadays one of the most attractive parameters of development. The building orientation affects directly the amount of energy consumption to achieve energy saving. The main objective of this study focuses on building orientation and its impact on energy consumption. One basic factor in building orientation affects the solar radiation exposure and hence the lighting, thermal acquisition, and equipment. The amount of energy consumption is computed in the Mediterranean climate using several orientations in two typical summer and winter periods. The proposed building simulation is modeled with basic orientation change to assess the energy consumption every 15 degrees using trnsys software and energy plus. The obtained results show that is the building orientation has a very important role in reducing total energy consumption.
