Life cycle energy analysis (LCEA) is used to assign energy values to product flows in each phase of an activity's life cycle. In the case of a residential building, this usually comprises energy embodied in the manufacture of building materials, energy used in the building's operation, and in periodic maintenance. In order to place these amounts of energy in a national context, the energy embodied in other goods and services consumed by householders also needs to be considered. This paper uses LCEA to demonstrate the need for considering not only the life cycle energy of the building but also the life cycle energy attributable to activities being undertaken by actual users of the building. The life cycle energy of an Australian residential building as well as common activities of households are analysed and simulated over a 30 year period using a worked example of a two bedroom, brick-veneer, semi-detached unit. The importance of considering the energy embodied in the initial construction of a residential building as well as the consumption of goods and services by householders is demonstrated as having long-term implications. In order to encourage sustainable living practices it is suggested that architects more closely consider the activities of householders when designing residential buildings, especially in temperate climates. The paper concludes by identifying future areas of research for LCEA in the residential sector. © 2000 Taylor & Francis Ltd.
