ABSTRACT
The aim of this chapter is to cover the principal methods of economic evaluation that can be used to calculate the economic impact of an investment project. By applying these methodologies, one can estimate the economic effectiveness of various building-retrofitting scenarios, as well as the efficiency of different types of building components. For example, some of the methodologies concern cost-benefit evaluation methods (i.e. the comparison between the receipt and the disbursement of an investment during a certain time period in order to evaluate the economic efficiency of the investment).
