ABSTRACT: One of the challenges for architectural science in changing climates is to provide
information on the types of buildings and urban form which are better adapted to a more efficient use of
energy. This is particularly relevant when most of this energy is derived from finite supplies of fossil
fuels. The energy consumed by residential buildings constitutes a significant portion of the total energy
used in operation of the built environment and, over the life cycle of dwellings, additional energy is
expended in the form of the embodied energy of materials used for construction and maintenance.

This paper summarises a project which evaluated both the operational and embodied energy of twelve
residential areas in Sydney. It particularly focuses on the techniques of estimating the embodied
energy of dwellings which included older detached dwellings of modest size from outer suburbs, large
two storey detached dwellings from wealthy suburbs and high density residential developments located
in inner suburbs.

The results indicate that the life cycle energy consumption and greenhouse gas emissions of the areas
comprising two storey houses are significantly larger than those of the inner suburb areas with
residential units. However, the life cycle energy consumption of inner suburban areas with apartments
was higher than that of some areas comprising single storey detached houses.
