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 are required. This research proposes construction of bio-based nearly zero energy or passive houses as one solution.
For this research paper, 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 ecofriendly
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, 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: bio-based house: Stone with lime foundations, wooden bearing
structure, straw bale walls, no traditional heating and air conditioning,
green roof, etc. House is designed to passive house standard.
. Type 2: concrete house: Type 1 geometry, but different building materials
(reinforced concrete structure with brick walls, Styrofoam insulation). It will be determined if this house complies with EU Standards in regards to energy efficiency.
This research proves that bio-based house is in compliance with Passive House Standards, more energy efficient and affordable to construct and maintain.
