Abstract
Given the rising living standard, population growth and global warming, buildings have been consuming energy and resources at an ever-increasing rate worldwide. To face this problem, energy saving techniques have been recently adopted in the framework of high-performance buildings, also known as zero-energy buildings. In Egypt, electricity consumption has witnessed significant increase of 55.22% since 2006 [1] of which residential and commercial buildings have the biggest share (66% to 74%). Hence, it is timely for Egypt to adopt energy saving techniques in its building construction code. This thesis investigates the effects of applying energy saving techniques for commercial buildings in Egypt. As a case study, a virtual building based on the Mechanical Engineering Department building at the Faculty of Engineering Campus of Ain Shams University, was modeled using EnergyPlus as a sample of non-residential buildings. A number of energy saving techniques have been assessed and compared to reach an improved building envelop and improved HVAC system with minimum energy needs (energy rationalization). Subsequently, a solar system is sized to cover these energy needs, thus transforming the sample building into a zero-energy building. Results of the study showed that Zero-energy buildings are applicable in Egypt and constructions recommended by international standards can be replaced by cheaper and more effective alternatives. Study also introduced simple design guidelines to achieve the Zero-Energy state for commercial buildings in Egypt.
