In 2007 a four-year project began towards optimising the sustainability of Belgian dwellings, focusing on environmental impact, financial cost and quality based on an integrated approach. The aim of this work is to evaluate the whole life cycle of representative existing and new dwelling types and formulate a preparatory policy document to evolve towards more sustainable housing.
This paper elaborates on a methodology developed and its implementation using three dwelling types. These dwellings are assessed during the first phase of the project; and the methodology is under further revision with a vision to apply it to representative dwelling types based on the results of our assessment.
The environmental impact is estimated based on life cycle assessment and translated into financial terms. In combination with the evaluation of the financial cost, this enables an investigation of the consequences if societal damages are considered. Moreover, a quality evaluation using a multi-criteria analysis is added to the assessment to support requirements for sustainability and enable comparison of non-identical functional units. The selected optimisation procedure is based on analysis of marginal improvements.
