Different Approaches to Sustainability Assessment and Applying life cycle Assessment for a Building in Sweden

Sammanfattning: The building industry has always been an attractive and influential topic in the energy consumption and using natural resources. This study is formed due to Sweden has program to increase energy efficiency in the building industries until 2020. And the energy consumption will be considered and assessed the life cycle of a building. The study is divided into two parts, rating labelling system and assesses the sustainability of a building, with the main focus on the second part. The building with the selected material according to Sweden construction standard and knowledge of skilled people are formed and assumed in Uppsala.As the result shows, energy consumption in the use of the building have the higher negative environmental impact compared to the construction of the building. Therefore, increasing the energy efficiency requires increased power generation efficiency and the increase buildings energy efficiency. Use of renewable energy like wind and solar energy can be an effective solution. Also, changing consumption pattern and using new technologies are considered as a means of reducing energy consumption.
