This project is part of the ATU Negresti Oas initiatives to improve the quality of urban life by applying measures to increase energy efficiency at both residential and public buildings, thus ensuring the implementation of the Energy Efficiency Improvement Program for the city of Negresti-Oas, Satu Mare County. The general objective of this project is to increase the energy efficiency of the Gymnasium School building no. 3 – Negresti-Oas Sports Hall, by applying measures to increase energy efficiency in order to reduce primary energy consumption and CO2 emissions, while ensuring the improvement of the comfort, health and safety of students and school staff – direct beneficiaries of the investment. The increase of energy performance at the level of the Gymnasian School building no. 3 – The Sport Hall of Negresti Oas will be ensured by carrying out intervention works that will reduce the energy consumption for space heating, in the conditions of ensuring and maintaining the indoor thermal climate, by limiting heat losses to the external environment as well as improving the urban aspect of the building. This project contributes to Romania’s effort to achieve the main objectives of the European Union’s energy and environment policy, ensuring the convergence of our country’s policy with EU policy in the field. In recent years, energy efficiency, mobility and climate aspects are of considerable importance in the city of Negresti Oas, as confirmed by the elaboration and implementation by the local authorities of the Energy Efficiency Improvement Programme for the city of Negres-Oas, Satu-Mare County. The city of Negresti-Oas thus aims to contribute to the achievement of the national objectives of climate change and sustainable energy by: reducing greenhouse gas emissions by 20 % by 2020, compared to 1990 levels; increasing the share of energy from renewable sources in gross final energy consumption to 24 %; increasing energy efficiency by 19 % in primary energy consumption. Thus, the Energy Efficiency Improvement Program for the city of Negres-Oas provides measures for the energy rehabilitation of buildings of public interest in the city of Negresti-Oas (education units, sanitary units, headquarters of the City Hall, etc.). This project therefore responds to the thermal rehabilitation measure of the Gymnasium School building no. 3 – the Sports Hall of Negresti-Oas and its energy efficiency increase, being a very important component of the investment plan provided by the local council.
