Abstract

Purpose: The purpose of this paper is to develop a methodology to test the robustness of energy performance of highly to fully glazed office buildings in hot and arid climates using the net energy figures. Design/methodology/approach: The paper uses a methodology to develop a base-case model for building energy simulation (BES) of highly to fully glazed office buildings followed by sensitivity analysis (linear regression model) to test the robustness of the results. Findings: Net energy is best achieved on south, followed by southeast, and southwest façadesof the bulding; the increase in d/l ratio has a diverse effect, while there is a significant influence of glazing systems on the resultant net energy figures. Research limitations/implications: The lack of experimental data for Integrated Façade System (IFS) with its various applications in the existing body of knowledge forms the main limitation of this research. Practical implications: Findings can be of practical use to practitioners and academics to assist them as a decision tool when working on the energy performance of IFS. Social implications: The research contributes to energy consumption reduction in office building stock at peak times, lowering the consequent energy shortage and blackouts for non-office buildings with clear positive social impacts. Originality/value: Adopting a systemic approach in BES studies will help further the understanding on the impact of some phenomena and justify how the contributory parameters would behave when combined effects are under investigations.
