Sustainable Building

Abstract
When striving for sustainable buildings, the focus is often set on the optimization
of the building environmental impact. In that perspective, the Life Cycle
Assessment (LCA) method is widely used to calculate the environmental impact
and through comparative studies, the preferred design options are chosen. As
costs are however a very important issue in decision making, it is important to
include costs in the analysis too. Although decisions are often only based on
investment cost, we recommend considering also the life cycle cost (LCC) to
guarantee long term affordability. This paper illustrates the importance of
considering both aspects by discussing the optimisation of 16 representative
residential buildings in Belgium from both an environmental and financial
perspective. The question raises how to handle contradictions between the results
of an LCA and LCC study of a building. The paper discusses and illustrates the
promising approach of monetary valuation of environmental impacts.
Recommendations are formulated based on the experience in the Belgian
context.
Keywords: life cycle assessment, life cycle costing, monetary valuation,
Pareto optimisation, weighting.
