Sažetak
Numerous public buildings in Croatia do not satisfy existing energy standards that results with an inefficient use of energy and unnecessarily high energy costs. According to the Directive of the European Union (Directive 2012/27/EU), the Republic of Croatia is obligated to reduce consumption of primary energy by 20% and to renew 3% of the floor area of heated and/or cooled buildings owned or used by central government by 2020, which can be achieved by energy renewal of existing public sector buildings as the leading consumers. The benefits of energy recovery investments can be grouped as following ; economic benefits in terms of cost savings for used energy, increasing building value ; ecological in the sense of more rational use of energy, reduction of CO2 emissions and other harmful gases, and other benefits of energy renewal as improvement of working conditions and health of employees etc. The aim of this paper is to explore the economic benefits of investments in energy reconstruction i.e. to determine whether the costs of used energy in buildings that have undergone an energy renewal process are different from before. The data of public buildings are collected from the Information System for Energy Management. This research includes public buildings reconstructed in the period from 2006 to 2016. For each building, the three-year average cost of energy consumed per square meter before the renewal was compared to the three-year average cost of energy consumed per square meter after the renewal process. The data are described by descriptive statistical analysis and compared by statistical test of expectations equality. This research can be beneficial to policymakers and institutions that are responsible for promoting energy efficiency.
