Parametric analysis of design stage building energy performance simulation models

The study finds that many similar issues exist in both building's design models, even though the buildings are in different countries, of different operational characteristics and had design models built at differing levels of complexity. The process of developing the most accurate design stage BEPS model is broken down into nine possible model stages and each of the nine is quantitatively assessed. The study gives pertinent guidance to an energy modeller as to the likely accuracy of their model, depending on what data has been used in the model's creation.
