Economic Evaluation of the Energy Efficiency Improvement Projects

Abstract

The process of adaptation of the buildings in architectural projects is codified by a set of energy efficiency regulations that are mandatory and which affect designers. To fulfil these requirements certain investments are necessary, which influence the economic performance of the project in construction phase, as well as in the long run over the building’s exploitation period. Therefore, an analysis of the economic effectiveness of the project is needed, which would also take into consideration the operation phase of the project, to include the whole life cycle. The methodology of the life cycle costs and savings analysis is presented in the following sections, which would be adjusted to the specific preconditions of the energy efficiency improvement projects, availability and possibility to gather relevant input data, as well as the perspective and understanding of architects as prospective analysis practitioners. The format of the proposed study is created to comprise several steps or phases, and their contents would be further elaborated. The methods that are applied include analytical procedure, comparisons, deduction and elaboration of the existing tools, and techniques and methods in the field of economic analyses in architecture and building construction. The resulting procedure allows for practical and theoretical implementation in actual projects. It is simple and straightforward to conduct, easy to understand, and open for expansion.
