Tiivistelmä
The subject of bachelor’s thesis is about energy efficiency of the building. Much attention is being paid to energy saving problems all over the world. In the first part it theoretic base for thermal performance requirements of buildings. It includes main positions of Russian requirements for thermal performance. Also it is about general types of building envelope. The second part is about energy audit of buildings. In this part there is an energy efficiency assessment methodology. Energy efficiency of the building in Saint-Petersburg was provided. There are three parts of them. In the first estimation of the energy efficiency was based on project data. In the second part assessments was on real values, and in the third part there are results of the thermal vision survey. Very important to take into account factors which influence heating regime of buildings. This part describes general factors such as relative air humidity inside the building, moisture content in the building envelope and air infiltration. In Finland, as in most developed nations much attention to energy efficiency of the building is paid. In this country method of building energy efficiency evaluation was created. In this case Finish norm (national building code D5) is used. The estimation of building energy efficiency was made. For correct comparison of two methods consumption of hot water and electric energy were not taken into account. Difference of methods was defined. Energy passport of that building was created. It is based on real values. Class of the building energy efficiency remained “Normal” by Russian method, but consumption of the heat energy rose. It is determined by reducing of the building heat protection characteristics, because there was another heat-moisture regime, quality of montage, latent defects during construction production on plant. Thereby, necessity of providing a building energy audit is confirmed.
