Towards Achieving Sustainable Environmental Efficiency: Rationalizing Energy used in Educational Buildings of University Campus

Abstract

Abstract The research deals with a practical and analytical study comparing the use of the computer program for digital simulation, Design Builder, to calculate the amount of energy consumption in buildings, as the aim of the research is to conclude the most influential architectural elements in reducing energy consumption in the typical building of Al-Azhar College of Engineering for Girls (CEG). This is done by calculating the amount of energy consumption of the college building with its existing specifications while making architectural modifications to the building to conclude which elements have an impact on reducing energy consumption under the influence of the climatic conditions of the city of Cairo. These architectural elements include treating the glass surfaces and curtain walls in the building and increasing the operating temperature of the air conditioners to cool the building, as it is clear from the simulation results that the greatest reduction in the building’s cooling load is by 40%. The research concludes with recommendations that contribute to energy rationalization in educational buildings on campus, thus achieving efficiency in the internal and external environment.
