Validation of an Energy Demand Model of Residential Buildings

Abstract: This paper presents a validation of an energy demand model of residential buildings. This model quantifies electricity and city gas demand of a house in the 5-min resolution as the sum of consumptions by all home appliances used in the simulated house. In the model, time allocation of household members in a day is first stochastically simulated. This time allocation data is then converted to the operation of home appliances and equipment. For this conversion, a probability showing how frequently considered appliances and equipment is operated when a behavior is undertaken is given as an input data. By using this probability, the operation of appliances is randomly determined. Finally, energy consumption of each appliance and equipment is determined by considering specification of the appliances. After explaining the simulation model, we validated the model by comparing simulation result with electricity demand measured from 227 households.
