Abstract: Like any other industry, the construction industry also emphasizes innovation, non-traditional thinking and alternative thinking. At present, when sustainable development, ecology and people s awareness of environmental impact become more and more important, low impact architecture can become an innovative alternative construction technology in the highly industrialized construction sector. In this paper, three kinds of walls made of locally available materials are compared. According to the construction time, they can be classified as biological resource materials. The M2 of the wall allows us to decide which construction technology is more favorable in terms of construction period. Shorter construction time means lower labor cost and lower ex factory priceenses for construction machines. In order to obtain answers to the questions posed, the authors made extensive searches of source data on the time-consuming building works which used locally sourced materials. Reference is made to “Temporary principles of erecting clay buildings” issued by the Institute of Housing Construction in Warsaw (Poland). Three types of walls made of locally sourced materials were studied: a wall made of clay blocks insulated with mineral wool boards, a wall made of clay compacted in formwork, and one insulated with mineral wool boards and wooden frame structure filled with straw bales and cladded with fibreboards. The layers have been chosen in such a manner that heat transfer coefficient values for the studied variants are as equal as possible (0.2 W m2 K), thus allowing a reliable comparative study.
