Energy upgrade of school buildings

The greenhouse effect has been a major contributor to the formation of the European Union legislation concerning Energy technology systems and the use of more efficient and “greener” systems in the buildings sector. The European Directive 2009/28/EC is promoting the use of renewable energy in every sector, such as residential and public buildings, but also in office and industrial buildings. To achieve the goal set, another European Directive was issued. According to the European Directive of 2010/31/EU there has been an establishment of a general guide concerning the evaluation and calculation of each building’s energy efficiency status. Thus all existing and future buildings must be subjected to an energy audit to determine the existing energy efficiency status or the future energy efficiency status of the building that is in the design process. The evaluation of each public building’s energy efficiency status is a priority, as it is a building that is used by many people and a minimum energy efficiency status must be established. Thus the subject of this paper is to evaluate the energy efficiency status of an existing public building, according to the standards set by the European Directives , make proposals to improve the efficiency of the building’s systems and provide an approximate estimation of the energy savings with the use of the Edge application.
