UNWRAPPING THE DEVELOPMENT AND THE POTENTIALS OF THE GREY BOX MODELLING APPROACH

Sadaf Alam, Marcus Keane

Abstract: With the growing increase in the population and comfort demands of people, the world’s energy consumption and associated CO2 emissions are increasing rapidly. Taking that into account, several energy efficiency measures in buildings are required during Building life-cycle concept. However, once the building operates, it shows the existence of mismatch between the predicted and real energy consumption, which is known as “Energy Performance Gap”. Hence robust prediction of building energy consumption is crucial for improved decision making towards building energy consumption and CO2 emissions. This paper describes the development and uptake of the data driven thermal network building simulation approach and its applications for making simplified thermal models of buildings by means of RC network, thermal resistances (R) and capacitances (C). Through critical literature review, the study investigates the advantages, disadvantages, and improvements of different building energy simulation approaches. Further, within the framework of lumped parameter RC approach, we conclude some new proposals to expand the application of the lumped parameter RC modelling approach to other engineering and energy management fields.
