【 摘 要 】

The Recast of the Directive on the Energy Performance of Buildings (the EPB Directive) came into force on 9 June 2010. One of the main requirements of the directive is to set a definition of nearly zero energy building (nZEB). 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. The measures of thermal retrofitting of a dormitory to nZEB standard are presented in this paper. As there is no definition of nZEB for existing buildings in Poland, the paper presents a considerations of such a standard. Next, a set of thermo-modernization solutions are presented on a basis of existing building of a collective residence. The aim of the paper is to present the barriers that occur in such projects and solutions that can be applied to achieve the set goals. Building chosen for analysis is 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 thermal comfort within building.
