摘要：This study presents a life cycle assessment (LCA) of ten single family houses located in Eastern Slovakia with the aim to compare them in terms of the materials and technologies used. The main goal is to investigate and emphasize the reduction rate of environmental impact resulting from using green materials and technologies. Environmental impacts are determined by using eToolLCD software. Life cycle impact assessment (LCIA) categories of global warming, ozone depletion, acidification, eutrophication and photochemical ozone creation potential, as well as abiotic depletion potential - elements, abiotic depletion potential - fossil fuels, use of renewable primary energy resources, net use of fresh water, components for reuse and materials for recycling are determined within the cradle-to-grave boundary. Assessed family houses are built as a combination of conventional materials such as aerated concrete blocks, expanded polystyrene (EPS), extruded polystyrene (XPS) and roofing mineral wool and natural materials such as wood, cellulose, clay, straw and extensive vegetation roofs. Multi-criteria decision analysis points out that material optimization of building structures as well as the application of green technologies can ensure a considerable reduction of environmental impacts.
