In the context of the sustainability of housing, the assessment of interventions in the stock is of primary importance. So, one of the first requirements for a decision support tooi in this field is that it can compare renovation to demolition followed by new construction. In this thesis the model of the Eco-costs/Value Ratio is elaborated for housing in a way that it meets this requirement. The elaboration of this approach connects eco-cost estimating to the traditional economic cost estimating in housing projects. This way, the assessment of the environmental burden of a plan can virtually be executed without extra calculation activities. The model can indicate whether a certain alteration in a building plan, aimed at reducing ecological burden, is cost-effective or not. Application in a case study shows that new construction and renovation need different approaches as to improving their performances in respect of ecological burden.
