Building Life Cycle Energy Consumption Estimation Based on the Work Breakdown Structure

Abstract

Energy consumption of buildings is one of the major sources of greenhouse gas emissions, frequently accounting for around 40 % of the total energy consumption in urban areas. Reasonable sustainability assessment requires effective and efficient methods for energy consumption estimation of buildings. With an aim to improve the accuracy in building energy consumption estimation, this paper proposes a life cycle building energy consumption estimation method based on the work breakdown structure. For each basic work package, the relevant construction business information can support a more accurate estimation of energy consumption and thus the integration of all basic work packages can enhance the accuracy in energy consumption estimation.
