Database and simulation model development for modelling the energy use of non-residential buildings

This paper discusses modelling methodology of the energy use of a certain amount of building stock at the city/regional/national level. In the methodology, building stock is divided into several stock categories and unit energy consumption for each category is quantified by performing simulations using prototypical building models as simulation input each representing a building stock category. For accurately modelling the energy use and estimate potential contributions of energy-conservation technologies, classification of the building stock is crucial as it homogenizes the stock group. This paper quantitatively evaluates how classification of building stock according to a number of building properties improves the accuracy of simulation model.
