Abstract

Energy use in the building sector is considered among major contributors of greenhouse gas emissions and related environmental impacts in Australia and worldwide. While striving to reduce the energy consumption from this sector, it is important to avoid burden shifting from one building life cycle stage to another; thus, this requires a good understanding of the energy consumption across the building life cycle. Both embodied and operational energy must be reduced to minimize the enormous energy footprint and associated environmental impacts of buildings. Previous studies have shown the significance of both the energy required for building operation as well as the energy embodied in initial construction of buildings. However, there is a lack of understanding about the significance of total energy embodied in replacement of materials over a building's life. This study aims to investigate the combined effect of building and material service life on life cycle embodied energy requirements of residential buildings. Life cycle embodied energy of a house in Melbourne for an assessment period of 150 years was calculated based on minimum, average and maximum material service life values for the building service life of 50, 100 and 150 years. A comprehensive hybrid embodied energy assessment approach was used for the initial and recurrent embodied energy calculation for each scenario. The combined effect of building and material service life variations was shown to result in a reduction in the life cycle embodied energy demand in the order of up to 61%. This shows the importance of building and material service life considerations in designing, constructing, and managing the buildings in efforts to reduce energy consumption by buildings.
