Thesis


Evaluation of electrical energy usage for home appliances (2015)

The energy consumed by residential buildings has increased in the last two decades and accounts for a considerable portion of greenhouse gas emissions. The increase in number and uses of energy consuming home appliances, including those used for space heating and cooling, is the cause of this. The resulting increase in energy demand, particularly in extreme hot or cold weather, requires costly expansion of the electricity grid infrastructure. In order to reduce the end-use electrical demand and improve itsenergy efficiency, various policies and technologies have been introduced, such as then introduction of low energy houses and energy efficiency programs aimed at specific appliances. This thesis investigates electricity usage patterns of home appliances and their contribution to the total electricity consumption of dwellings by providing examples of new high-resolution (minute-by-minute) measured data. This study analyses the overall household and individual appliance energy usage data collected from monitoring systems installed within a number of low energy houses within the Lochiel Park Green Village (South Australia). In addition, householders were surveyed and appliance audits were conducted to collect information regarding households and their appliances. The key characteristics of households,such as demographics and physical attributes, as well as appliance ownership, are also summarised and examined. The electricity profiles of home appliances developed in this study shows how low energy houses and their appliances consume electricity in various time frames (e.g. yearly, seasonal, and monthly) and at times of their respective peak electrical demands. These profiles are compared with the data obtained from other studies, in order to evaluate the energy savings of appliances in low energy houses. The profiles are also used with appliances information obtained from surveys and audits, to identify the factors most likely to influence the appliance electrical demand. The high-resolution data show the detailed operation and use profiles of home appliances in actual environments and are compared to laboratory conditions used in relevant test standards. This thesis shows that a considerable reduction in household energy can be achieved in low energy houses, which is attributed to the overall decrease of electrical demand of all major appliances. Analysis of the appliance data demonstrates that outdoor and indoor air temperature is still one of the most influential parameters for the energy consumption of appliances within low energy houses, whilst other factors, such as the number of residents and the habitable floor area, are not as significant. Furthermore, this thesis demonstrates how various characteristics, such as family composition and life style of the households influence the electrical demand of home appliances. The result of this thesis provides empirical evidence that can be used to refine end-use electricity demand modelling for low energy housing developments in Australia. This information could be used to assist in the design and sizing of the electrical infrastructure required in new low energy housing developments.
