| Abstract | ||||
| The annual energy consumption rate in Egypt rises by 3.8% every year; traditional resources represent 92% of the generated energy. Taking into consideration the near depletion of their reserve and the included environmental issues with their use, it can be imagined that the energy situation in Egypt is disastrous. Therefore, improving the energy situation in Egypt became an urgent need. Reducing energy consumption in buildings, in particular, will help in reducing the overall consumed energy, since they consume 85% of the total energy production in Egypt. The design of roof slabs for thermal insulation purposes is required to reduce the energy consumed in buildings since they are accountable for 50% of the heat gain in a one-story building. By implementing passive cooling techniques, there are the chance to overcome the increased heat gain through roofs to reach the desired savings in energy. This search aims to evaluate the effect of different passive cooling techniques, applied to a student housing building's roof in Sohag University in new Sohag city in Upper Egypt, using building information modeling (BIM) platform. A review of the related scientific papers was carried out. Through this review, a matrix of 31 variables was conducted and applied to the building's roof. Energy consumption for every variable was calculated and compared to other variables. The findings proved that choosing the right passive techniques for roofs can help in reducing energy consumption by 46%. Also, some of these techniques may have a small effect on energy consumption. | ||||
