Abstract [en]

In this thesis, a comparison is made between the Nordic countries' energy requirements and classification systems for apartment buildings. The aim is to find out how different national requirements affect the building process and if it is possible to compare the energy performance requirement between the countries in a fair manner.The European Parliament and the European Union have together adopted a directive on energy performance of buildings indicating the objectives which the Member States must achieve. The aim is to reduce greenhouse gas emissions, increase renewable energy and create greater energy efficiency. However, it is up to each country to decide how to meet the objectives, which means that the country's building codes and self-regulation affects its implementation. The countries' energy demands are therefore very different even though they originated from the same EU directive.Previous studies show that there is no performance requirement that corresponds properly between the Nordic countries, and the various requirement models differ in views on energy efficient means.This study is based on the countries' current energy regulations and classifications for apartment buildings, and the results through an empirical study and interviews. The empirical study focuses on the countries’ main performance requirement that controls the building’s energy use. By examining what’s included in the definition of the building’s energy performance in each country, a common definition of energy performance is produced.Each country performs energy calculations, based on their own regulations, on a reference house that is designed by the authors, in order to see how energy use differs between the Nordic countries. Since both the literature study and the interviews suggested that Denmark has the toughest energy requirements, the authors started from a Danish low-energy building in the design of the reference house. Conclusions to be drawn from this study are that the requirement for energy performance of buildings is the one requirement that is most governing in each country. All Nordic countries have requirements on building's energy performance and the heat loss trough the buildings envelope, but the requirements are worded differently.The main differences depend on the number of energy bearers that are included in purchased energy / net-energy demand, default values and energy forms. The Nordic countries' energy classification systems are similar-looking, but because they are based on national requirements and methods for calculating energy performance, it is not possible to compare them without further ado. Furthermore the authors conclude that it’s not fair to directly compare the numerical energy requirements and classification system with another. But with the help of the reference house and the authors developed definition of energy performance of buildings, where only energy for heating, cooling and operation electricity are included, the study shows that it is possible to make a comparison between the Nordic countries.
