“…Ensuring proper hypothesis of prediction, perfect tuning of building services, and functioning of the facility as designed are important factors to monitor the simulation of the building. This has resulted, in the narrowing of the gap between actual energy consumption and estimated energy consumption (Vázquez et al, 2011). Further, Vázquez et al, 2011 mentioned that investigating and creating general models to observe the behaviour of tenants in buildings and using them in energy consumption prediction can reduce variations.…”

“…This has resulted, in the narrowing of the gap between actual energy consumption and estimated energy consumption (Vázquez et al, 2011). Further, Vázquez et al, 2011 mentioned that investigating and creating general models to observe the behaviour of tenants in buildings and using them in energy consumption prediction can reduce variations. Simple observation, obtaining readings, and generating a model to predict energy more absolutely, with the use of basic monitoring results will help to input the energy model with accuracy and predict the actual performance of the building (van den Brom et al, 2018;Gram-Hanssen and Georg, 2018).…”

Operational energy consumption in buildings has a crucial impact on global energy consumption. Nevertheless, significant energy savings can be achieved in buildings if properly designed, constructed, and operated. Building Energy Simulation (BES) plays a vital role in the design and optimisation of buildings. BES is used to compare the cost-effectiveness of energy-conservation measures in the design stage and assess various performance optimisation measures during the operational phase. However, there is a significant ‘performance gap’ between the predicted and the actual energy performance of buildings. This gap has reduced the trust and application of the BES. This article focused on investigating BES, reasons that lead to a performance gap between predicted and actual operational energy consumption of buildings, and the ways of minimising the gap. The article employed a comprehensive literature review as the research methodology. Findings revealed that reasons such as limited understanding of the building design, the complexity of the building design, poor commissioning, occupants’ behaviour, etc., influence the energy performance gap. After that, the strategies have been identified to minimise the energy performance gap such as proper commissioning, creating general models to observe occupants’ behaviour in buildings, and using the general models for energy simulation, ensuring better construction and quality through training and education, etc. Further, the findings of this study could be implemented by practitioners in the construction industry to effectively use energy simulation applications in designing energy-efficient and sustainable buildings.
