Benchmarking the practice of validation and uncertainty analysis of building energy models

The practice of validation and uncertainty analysis (UA) building energy models (BEM) is critically reviewed. background for this review the recognized need improvement accuracy in prediction performance, e.g. as part an efficient mitigation response to climate change. was performed using benchmark comparison verification (V&V) frameworks obtained from field scientific computing. First, current V&V BEM reviewed, with a special focus on UA, existing experiments (VE), used provide measurement data required BEM. Second, included case study European International standard BEMs, CEN ISO 13790 52016–1, calculation hourly use space heating cooling. From perspective frameworks, conclusion that these cannot be considered validated. Based present review, suggestions are given how strengthen Building Information Modelling (BIM) initiative its support development accurate Finally, challenges terms identified, where most important increase degree consensus among scientists procedure condition creating scientifically based BEMs. • Current Comparison made computing Benchmarking shows standards 52016–1 not validated could Important challenge
