Building performance characterisation and assessment based on in-situ measurements

Decreasing the energy use in buildings can only be achieved by an accurate characterisation of the as-built energy performance of buildings. This is mainly for two reasons. First of all, despite the ever more stringent energy legislation for new and renovated buildings, monitoring the actual energy performances often reveals a significant performance gap with the theoretically designed targets. Characterisation by monitoring hence ensures that the set requirements are met. Secondly, the ever increasing need for integration of renewables stresses the existing energy systems which can be remedied by using intelligent grids that are aware of the actual status of the buildings in a district. This intelligence requires an accurate characterisation of the building.

The current project aims for a reliable characterisation and assessment of the actual performance of buildings by optimised in-situ measurements combined with statistical dynamic data analysis techniques. The focus lies on the development of characterisation methods for residential buildings based on on-board monitoring techniques. This project aims for quality assessment methods,pinpointing the most relevant building performance indicators, such as the overall heat loss coefficient, and develops identification methods, translating the dynamic behaviour of a building into a simplified model that can be used in model predictive control, fault detection and optimisation and operation of district energy systems.
