The energy performance of a building is essentially determined by the (1) thermal characteristics of the building envelope, (2) installed services and (3) building usage. As the latter is not easily predicted nor controlled, the first two are decisive in achieving the envisaged building energy performance, both for new buildings and renovations. The theoretical energy use calculated on the basis of building plans and specifications, in order to meet building regulations or specifications by the builder, determines the anticipated performance. It may differ, however, from the actual ‘as-built’ performance in a significant way. The IEA EBC Annex 58-project on ‘ Reliable Building Energy Performance Characterisation Based on Full Scale Dynamic Measurements’ is working on this gap between actual and calculated performance of the building. A consortium of researchers and industries from 15 countries are developing knowledge, tools and networks to achieve reliable in-situ dynamic testing and data analysis methods that can be used to characterise the actual thermal performance and energy efficiency of building components and whole buildings. This seminar gives an overview of the current knowledge in the field of energy performance assessment. It aims also at looking into the future of new applications and answers how to close the gap between calculated and real performance.
