Comparison between Different Simulation tools Applied in Evaluating Energy Performance (Scope: Commercial Buildings): Review

Abstract

This study reviews earlier investigations that looked at the problem of enhancing energy efficiency in commercial buildings and comparison between different simulation tools applied in evaluating energy performance through the application of computer algorithms. The research chooses earlier works that concentrated on energy conservation in commercial buildings using an analytical method. After analyzing previous studies, the research reached a set of results, the most important of which are: The overall primary energy consumption of a building model in all climatic zones dropped by 2% and 15%, respectively, when optimal window dimensions and placement were used. The ideal range for the lowest and maximum WWR is from 10% in the hot climate zone to 36% in the cold climate zone. It is advised to utilize square windows in cold climates and long horizontal windows in hot climates since the aspect ratio ranges from 2.2 to 8.7 in the south orientation in both hot and cold temperature zones. To reduce the building's energy consumption in hot climes, wide windows should be positioned on the north side of the structure and tiny windows on the south.
