General objective: Supporting energy efficiency, smart energy management and renewable energy use in public infrastructures in Sibiu Municipality. Our project aims to support energy efficiency, smart management of renewable energy in public infrastructures located in Sibiu Municipality. The implementation of this project will bring significant benefits both in terms of energy saving that has a significant financial impact on the owner, and from an environmental point of view, by using natural resources to produce energy. We chose to carry out this project because reducing energy consumption and energy efficiency is one of the main objectives of the European Union and thus one of the objectives at national, regional and county level. At the same time, the EPBD (2010/31/EU and 2002/91/EC repealed) imposed strict energy performance standards and a number of other requirements for new and existing buildings. In order to contribute to these objectives and to comply with European legislation, there is significant potential to reduce consumption, especially in energy-intensive sectors, including public buildings, especially those with social functions, such as the Hospital of Pneumophysiology Sibiu. At the same time, this project provides for measures to reduce total energy consumption through the use of renewable sources. Given that non-renewable energy resources are being exhausted and for the European Union to reach a 20 % share of energy from renewable sources in gross final energy consumption by 2020, binding national targets have been set for each Member State, including Romania, for which the national target is 24 %. Thus, Romania must create a legal framework and mechanisms for directing European funds in the exploitation of renewable energy sources. Moreover, according to European commitments, Romania needs to improve its energy efficiency by 19 % and reduce greenhouse gas emissions by 20 % by 2020.
