Life Cycle Analysis (LCA) is the assessment of the total cost or benefit of an asset over its lifetime. Also referred to as Whole Life Costing (WLC), LCA systematically considers all relevant costs and revenues associated with the acquisition, ownership and disposal of an asset. LCA supports a comprehensive assessment of sustainability by considering all benefits and impacts within a Triple Bottom Line Framework.
In this paper I look at the components that comprise a comprehensive LCA and some of the factors to be considered in evaluating the life cycle cost or benefit of an asset. These costs or impacts as well as accrued benefits are also considered from the perspective of the Environmental and Social Bottom Lines.
