Abstract

Studies that attempt to model real patterns of residential occupant behaviour have become increasingly popular over the last decade. Most research of this kind tend to produce behaviour profiles based on an average occupant, yet the prediction of residential energy consumption varies significantly according to behavioural profiles of individual households. Oftentimes, averaged behavioural profiles are inadequate for predicting energy demands accurately, therefore requiring models to incorporate the diversity of occupants’ behaviours. The main objective was to develop an air-conditioning (A/C) usage model that produces diverse A/C cooling and heating operation patterns in residential settings. Longitudinal field observations were conducted in 41 Brisbane region households of Australia over a one-year period. Regression coefficients in the model were set to be drawn from a normal distribution to reproduce observed variability in A/C operation patterns amongst the households. Simulations were performed on a validation dataset to test the predictive skill of the model. The result indicated that the frequency and duration of A/C usage observed in the validation dataset well matched with the prediction made by the model. The proposed model could be incorporated in building energy simulation tools to predict realistic energy use for A/C in a given residential building design.
