Methodological Evaluation of Family House with Different Thermo-Physical Parameters of Building Materials

Abstract

Paper is focused on the assessment of two alternatives of family house from environmental performance. Environmental impact categories such as Global warming potential (GWP), Acidification potential (AP) and Eutrophication potential (EP) expressed as CO2eq, SO2eq and PO43−eq using the LCA assessment method are presented. Alternative solutions of building materials are also compared from phase shift of thermal oscillation. Results show that natural building materials are characterized by lower environmental impacts expressed as equivalent emissions of CO2 (6%), SO2 (24%) and PO43− (44%). The wood fiber board can store nearly 24 times more heat than the mineral wool. The wood fiber boards have a phase shift of thermal oscillation of 7–13 h, while other insulation materials only about 3–4 h.
