Abstract [en]

The Swedish building and construction sector contributes greatly to negative environmental impacts, while its environmental protection measures are marginal. Life cycle costing (LCC) has been used successfully for procurement and investment decisions, but its use within the Swedish building and construction sector is limited. This paper combines LCC with an environmental approach employing monetised environmental impacts. The prototype developed was evaluated in a case study. The aim was to investigate the cost items that could be educed, how the results were perceived, the problems encountered and the kind of results that can be obtained using the tool. The case study, at a Swedish housing company, showed that data about the investment (costs and quantities) were readily available. Data on quantities are important for deriving the environmental impact. A greater understanding of external costs as a valuation of the environmental impact is needed in order for the results to be used efficiently. However, it is important to bear in mind the crucial importance of sensitivity analyses, e.g. varying the interest rate or future cost changes, and of dividing internal and external costs in order to avoid double-counting.
