Conventional buildings play important role considering the consumption of resources, energy and production of emissions. These serious environmental problems demand an urgent global response. Selection of building materials from the initial phases of building design predetermines the best chance to influence the total intensity of environmental performance. In this paper the environmental assessment in terms of used materials of two conventional Slovak dwellings - standard house from conventional materials and energy passive house from green materials is presented. Despite the fact that the most studies present that improving energy performance of building envelope reflects the increase of embodied energy and emissions, the results demonstrate that the green alternative achieves better environmental potential for all evaluated parameters. The innovated approach using traditional Slovak plant materials such as timber or straw assures elimination of carbon footprint of whole house thanks to the ability of plants to lock a substantial amount of carbon in their mass. Optimization of material compositions of this case study has proven that the reduction of Primary energy intensity by 49.8%, as well as reduction of amount of SO2 emissions by 26.4% and greenhouse gasses emissions even by 164.4% can be achieved by utilization of suitable materials.
