Abstract:
We describe the development of an energy performance assessment system to evaluate the energy performance of existing building to deliver energy efficiency improvements by building remodeling. In consideration of the performance effect of building structure and operation, this system uses two kinds of building energy models such as ISO 13790 and EN15232 to calculate the energy consumption of building. In order to run the accurate building energy model, we use bill based energy consumption data and Bayesian calibration method to find current value of uncertainty parameters such as performance coefficient and deterioration coefficient of various building components. So, this system can accurately evaluate the energy performance of an existing building. Also, it can provide Energy Conservation Measures (ECM) for remodeling of existing building. The proposed system can be used as an effective and accurate energy performance assessment tool for improving energy efficiency of existing buildings through building remodeling.
