heal.abstract
The energy performance of buildings is rather important from both economic and environmental aspect. The evaluation of the energy performance of buildings is the first step for improving the energy efficiency of the building stock. Energy efficiency measures that improve the energy inefficient parts of a building can be implemented given that they are economically feasible. The evaluation of the energy efficiency of the International Hellenic University building is conducted and possible improvement suggestions, such as thermal insulation and replacement of the heating system, are presented. The feasibility of the suggestions is investigated using economic factors for evaluating the economic viability of the projects suggested. The factors used are the depreciated payback period, the net present value, the internal rate of return and the savings to investment ratio.
