Kurzfassung englisch:
In order to reduce the amount of energy being spent in the construction industry and to achieve the EU Climate and Energy Package goals by 2020, new ways of constructing houses is required. This research proposes construction of bio-based nearly zero energy or passive houses as one solution.

Typical house construction methods in the Balkan region are analysed and compared to current Austrian house construction methods (in particular straw bale house built to passive house standards), since Austria is now one of the leading countries in Europe when it comes to offering smart and eco-friendly construction methods.

This paper aims to enhance the understanding of the environmental performance of straw bale house in the Balkan region, develop the mainstream acceptance and use of straw as a construction material by proving that, such home is not only healthier for the environment, but also economically justifiable to construct than concrete/brick homes usually built in this region of the world.

This is done via energy analysis in both BIM and Baubook software and construction cost calculation and comparison of two different house types virtually placed in Bosnia and Herzegovina as a representative country of Balkan region. Type 1 is bio-based house, while Type 2 is concrete house of similar geometry.

During the analysis, it was discovered that Type 1 house is in compliance with passive house standards, while Type 2 isn't. Furthermore, energy use intensity according to BIM analysis for Type 1 is half of the value of the Type 2 house. Peak heating load for Type 2 house is much larger than for the Type 1 house. Global warming potential of Type 1 house is negative, which means that bio-based materials absorb CO2 during its life. Global warming potential for Type 2 is 435.02 kgCO2/m2. In addition to this, it costs slightly less to construct Type 1 house than Type 2 house.

Therefore, this paper proves that Type 1 - Bio-based house is cheaper to construct and more energy efficient than Type 2 - Concrete house that is typically being constructed in the Balkan region.
