Comparative Studies and Research on Energy Optimization of Non-Residential Buildings

Statistics confirm that in the EU, buildings consume approx. 40% of final energy, which accounts for 36% of total European greenhouse gas production after energy consumption. Energy efficiency measures are urgently needed to effectively reduce greenhouse gas emissions. Decreasing fossil fuel consumption would have a major impact on declining energy demand per unit of gross domestic product. In 2014, European leaders adopted the ambitious Climate and Energy Framework 2030, in which the three key targets were raised: a 40% reduction in greenhouse gas emissions by 2030, a 27% reduction in RES and a 27% increase in energy efficiency. Then, in November 2016, the European Commission (EC) proposed the Clean Energy for All Europeans package, designed to support and accelerates the transition to a carbon-free energy system. This paper comprises a case study of the current situation of these matters in Romania and focuses on steps and methodology of what actions are reliable and available to be put into practice on this matter.
