Most of the EU member states have already set a definition of nZEB for new buildings and some of the countries also done it for existing buildings. As there is no definition of nZEB for existing buildings in Poland, the paper will include various considerations of such a standard. Next, a case study of educational building retrofitting to a proposed nZEB standard will be presented. The aim of the paper is to present what measures can be used in order to decrease energy consumption in existing building. The measures are divided into three parts: architectural and construction, installations and energy sources. Thus a complexity of the solutions are presented. As the nZEB standard is related to available energy sources, also an influence of local condition will be considered. Building chosen for analysis is located in an area under historic protection which makes the work even more difficult. It was proved that used solutions were chosen not only to reduce energy demand or increase energy production from renewable energy sources, but also to increase social and aesthetic features of the building.
