Improved environmental impact in the architecture industry: LCA analysis of an alternative masonry element

Abstract The environmental performance of a building used for living or working depends to a large extent on its design and structure, but the total impact has additional influencing factors as well. The role of masonry elements is especially important when taking the entire life cycle of a building into consideration. This paper aims to analyze the environmental impacts of producing and using an alternative masonry element (AME) which is composed of natural cellulose and biodegradable three-component glue. The direct goal is to compare the environmental impacts of the alternative masonry elements and traditional ones. The calculations model the total life cycle of the elements, including the collection of raw materials and the post-use treatment. Calculations are supported by GaBi Professional software. The study also covers alternative plant installation possibilities in different countries which employ different energy-mixes to cover the energy used for production. Results of the study show that remarkably saving can be achieved when using the new alternative masonry element.
