Abstract
The Building Sector in Saudi Arabia is growing rapidly. Electricity demand grows alongwith this growth. The more demand means more emissions to the environment. To satisfy this demand and help the environment with lower emissions, the concept of Net Zero Energy Building (NZEB) can be a solution. Although, it sounds hard to achieve a NZEB in Saudi Arabia due to the extreme hot weather that consumes high amount of power on cooling, this study prove that it is possible. In this study, a model of 23,300 m2 two-floor building was developed in Revit and eQuest and was validated. The model was used to analyze the building energy performance in three locations in Saudi Arabia, namely Dammam, Riyadh, and Tabuk where each city has a different weather condition. The source of energy used is solar energy and the solar energy analysis were performed in HelioScope. The model with a total area of 495,207 ft2 was able to produce energy using
solar panels with 4,338,030 kWh/year for Dammam, 4,518,630 kWh/year for Riyadh, and 4,592,062 kWh/year for Tabuk. On the other hand, the consumed energy for Dammam is 3,749,600 kWh, 3,550,200 kWh for Riyadh and 3,549,400 kWh for Tabuk. For all three locations, the produced energy exceeded the required energy that the building in each location consumed. This proves that Net Zero Energy Building concept is achieved.
