LIFE CYCLE ANALYSIS FOR ENERGY ACCOUNTING IN RESIDENTIAL ARCHITECTURE
Authors: Henriksen, Janet
This paper aims to quantitatively evaluate the issues of lifestyle, energy use and embodied energy, in
a typical household in a temperate zone.
Technical research into energy in buildings previously has focussed on two aspects: the embodied
energy in materials used in construction and in the energy used to heat and cool a building.
This paper draws together these two areas of study and evaluates them in terms of typical lifestyles in
a structured way, to form a hybrid framework for a holistic accounting process to assist decision
making. The power of computer modelling programs is used and the results evaluated in the context
of lifestyle and economics. The BHP Steel LISA program, which assesses the impact of the materials
used, is linked to NatHERS, a program used to analyse comfort and energy use.
The method developed allows analysis that can verify benefits of various strategies that previously
had no clear method of design due to the inherent complexity of residential design in temperate
