Abstract
The aim of this case study was to evaluate the energy performance of utilizing different external materials reaching sustainable targets. Buildings are responsible for 40 percent of energy consumption and energy performance of buildings is a key element to achieving the European Unions goals. The EU has pledged to cut its consumption by 20 percent by 2020.The main objective of this research was to explore the suitability of BIM for sustainabil-ity analysis at the conceptual design process. The procedure included analysis and discussion of the results for the lowest energy performance of materials. It was shown that changing the building envelope had a signi cant e ect on the annual energy performance of the case building. The limitations of the study was the limitations in the software. For further research, the paper nds it expedient to perform a even more detailed simuation analysis on the building design with other energy supply systems.The value of the paper is to highlight the utilization of BIM to evaluate the material solutions to reach sustainable construction in the future, focusing on the need for lowering the energy consumption of tomorrows buildings.
Highlights
In 2015, the residential- and building sector counted for almost 40% of the energy consumption and 40% of the material used in Norway
The energy- and environmental challenges make it necessary to build with quality and aim for regular renewal of the existing building stock
There is a demand for nearly zero energy buildings that are scheduled for the end of 2018 for buildings owned by the public, and by the end of 2020 for new buildings [7]
Summary
In 2015, the residential- and building sector counted for almost 40% of the energy consumption and 40% of the material used in Norway. Designing minimum energy performance buildings is an arduous challenge This requires exploring a huge number of design solutions and specifications of each building element. This current study introduces the necessary theory behind sustainable low energy building design and the definitions of ZEB [44]. In 2015, the residential- and building sector counted for almost 40 percent of the energy consumption and 40 percent of the material use in Norway [4]. As the population of Norway continues to grow, it is important to plan the urban communities with long term sustainability in mind This doesn’t necessarily include low energy buildings and emission buildings in particular it is just a part of the social transformation [6]. There is a demand for nearly zero energy buildings (nZEB) that are scheduled for the end of 2018 for buildings owned by the public, and by the end of 2020 for new buildings [7]
