本文回顾了预测和测量的能源使用之间的差异，在英国的背景下，展望全球研究的非住宅建筑。它解释了能源绩效量化之间的差异，并将这种能源绩效差距归类为合规性或绩效建模与测量能源使用之间的差异。文献来源进行审查，以表示预测和测量的能源使用之间的幅度，这是发现偏离+34%，标准偏差为55%的62栋建筑物。它继续在描述的性能差距的根本原因，存在于建筑生命周期的所有阶段，并确定了主要因素是有关规范的不确定性建模，居住者的行为和不良的操作实践，估计影响20- 60%，10-80%和15-80%的能源使用。其他具有高度影响的因素与建立能源性能目标、早期设计决策的影响、建模中的启发式不确定性和居住者行为有关。最后，讨论了减少性能差距的行动措施和反馈过程，指出需要制定能源使用立法，深入了解设计阶段模型，获取能源数据，并扩大研究工作，以实现与预测性能相关的建筑性能
This paper reviews the discrepancy between predicted and measured energy use in non-domestic buildings in a UK context with outlook to global studies. It explains differences between energy performance quantification and classifies this energy performance gap as a difference between compliance or performance modelling with measured energy use. Literary sources are reviewed in order to signify the magnitude between predicted and measured energy use, which is found to deviate by +34% with a standard deviation of 55% based on 62 buildings. It proceeds in describing the underlying causes for the performance gap, existent in all stages of the building life cycle, and identifies the dominant factors to be related to specification uncertainty in modelling, occupant behaviour and poor operational practices having an estimated effect of 20-60%, 10-80% and 15-80% on energy use respectively. Other factors that have a high impact are related to establishing the energy performance target, impact of early design decisions, heuristic uncertainty in modelling and occupant behaviour. Finally action measures and feedback processes in order to reduce the performance gap are discussed, indicating the need for energy in-use legislation, insight into design stage models, accessible energy data and expansion of research efforts towards building performance in-use in relation to predicted performance
