【 摘 要 】

Occurrences associated with the phenomena of climate change are increasingly visible. Effects of progressive environmental pollution are monitored with growing concern. Still, in the construction sector, the choice of sustainable materials and the knowledge concerning them is insignificant. Studies have shown that single-family residential buildings form the largest share of new buildings in Central European countries. It should be assumed that it is the improvement of this particular section of the construction sector to be the goal of further development of societies. This paper presents a case study of the construction of a house using straw - a material that, on the one hand, is a product associated with local tradition, while significantly reducing carbon footprint of its production and use, on the other. The construction of a prototypical house with the application of composite technology, i.e. timber framing with straw bale infill, was compared with a conventional method (ceramic masonry units) which is currently the most popular choice for building single-family houses in Poland. The study is based on the building’s life cycle assessment (LCA) over its consecutive phases as a tested and reliable method of the verification of a material’s impact on the environment.
