Abstract
Higher education buildings represent a category of buildings that consumes a significant amount of energy; thus, contributing remarkably to the total energy consumption of any country. In this paper, an energy audit was conducted in a higher education building for summer load taking the building of the electrical engineering department in Assiut University as a case study. The building is of a total floor area of around 3604.5 m2, and located in a hot summer climate of the Egyptian city of Assiut. A detailed description of the building, its directions and the places inside the building are introduced, and a full weather analysis of the region surrounding the building is conducted. Moreover, human activities inside the building are discussed, and an analysis of energy consumption and load classification of the building are introduced. The three main pillars of this study are scheduling the rated nominal power of all appliances in the building, measuring the actual energy consumption of the building, and correlating between them through two important drivers, i.e., weather and human activities. The analysis shows a strong effect of human activities in controlling energy consumption in the building so the consumption increases on school days and decays on holidays.
Key words: Energy analysis; Energy audit; Human activities; Educational building; Weather analysis; Load classification.
