Comparison of environmental impact of building materials of three residential buildings

Building industry is responsible for 1/3 of total CO2 emissions and consumes 40% of primal energy in the industry. This paper presents the results of environmental impact assessment of building materials in three houses based on Life Cycle Assessment of the whole life cycle. Building materials were evaluated by special tool by Createrra. CO2 emissions related to life cycle of building materials vary from 0,176 kg CO2eq/kg − 0,305 kg CO2eq/kg, SO2 emissions range form 0,836 g SO2eq/kg − 1,656 g SO2eq/kg and primal energy intensity reached values from 2,347 MJ/kg to 2,534 MJ/kg
