Energy Performance of Buildings Through Economic Efficiency

Abstract

Ensuring the energy performance of buildings is essential for social resilience and sustainable communities. Achieving the required performance is possible by implementing different energy efficiency measures. The basic principle for identifying and prioritizing potential energy efficiency measures and renewable energy sources is "ensuring maximum utility at minimum cost". This means ensuring thermal comfort in rooms, providing the required level of artificial lighting and meeting the required level of sound insulation through recommended energy efficiency measures.

The aim of the research is to develop and provide a practical methodological tool to support pre-investment decisions on energy efficiency projects for buildings. The research focuses on the national normative-methodological framework in correlation with the international one. Various research methods are applied such as analysis and synthesis, comparative analysis, mathematical and statistical calculation methods. Conclusions are verified through case studies. The outcome of the research allows building owners and managers to identify energy efficiency measures according to their financial resources, to prioritize them and to substantiate the decisions they receive.
