This paper deals with life cycle analysis of three wooden houses in terms of environmental impact indicators, construction, and operational costs. At the same time, indoor environmental quality of the houses is investigated. From the results achieved, it can be concluded that wooden house 3 shows the lowest emissions of CO2e/m2.year compared to other houses. Based on overall investigation wooden house 1 is the most advantageous. Concrete structures and mineral wool have the highest share of global warming potential. On the contrary wooden house 3 has the largest life cycle costs. Results of indoor environmental quality show that the permissible limits of the measured physical and chemical factors are not exceeded during the measurement.
