Online energy performance monitoring and evaluation for continuous commissioning in a danish office building

The development, implementation, and evaluation of an online building energy performance monitoring and evaluation ‘ObepME’ platform in a 2600 m2 Danish office building is presented and discussed. A whole building dynamic energy model was developed in EnergyPlus and calibrated using actual onsite data. The calibrated model is then used as a basis for continuous and automated commissioning. A list of performance tests was developed targeting energy consumption on different levels. An online dashboard was created to automatically compare and visualize model simulations and actual building consumption as part of the building continuous commissioning. The model development and calibration along with ObepME implementation are presented in this paper. Major findings from the continuous commissioning platform and examples of malfunctions observed are reported and analysed.
