Abstract
The aim of this paper is to present a method and a tool based on cost-effectiveness analysis (CEA) for assessing energy efficiency
improvements in buildings. The method is based on comparing costs of an energy efficiency improvement with its effects in
terms of reduced energy use. A short review of the current practices in evaluating the economic efficiency and feasibility of
energy efficiency measures is presented. A case example is presented with a calculation by using a CEA calculation method
adapted for energy efficiency improvements in buildings. It is here concluded that the systematic appraisal of cost-effectiveness
of energy efficiency investments would allow most economical projects to be implemented first, leading to greater overall
economic efficiency
improvements in buildings. The method is based on comparing costs of an energy efficiency improvement with its effects in
