Reduce Household Energy Consumption Using Passive Methods

Recent researches and studies demonstrate that the need for sustainable buildings which do less impact on the environment is rising in the worldwide 1, 2. Not only the energy generator from energy supply side needs to be considered to build a sustainable building, but also the novel construction methods and materials from demand side will contribute to the energy saving. The aim of this study is to carry out an investigation of a property's energy consumption from the view of passive energy saving, and then use the results to determine the best energy saving plan. A field audit and the Design Builder software simulation of a detached house were carried out during this study. The results indicate that the simulation energy consumption (9.66MWh) is matching well with the actual energy usage (9.76MWh) and the property consumes less energy than national average (16.90MWh). From the study, it is found that the annual total household energy consumption reduced for about 33% than traditional construction materials and technology by using passive energy saving methods.
