Construction Time of Three Wall Types Made of Locally Sourced Materials: A Comparative Study

Abstract

Similarly to any other industry, the construction sector puts emphasis on innovativeness, unconventional thinking, and alternative ideas. At present, when sustainable development, ecology, and awareness of people's impact on the environment grow in importance, low impact buildings can become an innovative alternative construction technology for the highly industrialized construction sector. e paper presents a comparative study of three walls made of available materials used locally, which can be classified as biosourced materials, in terms of construction time. e comparison of times necessary to make 1 m 2 of the wall allows us to decide which building technology is more advantageous in terms of the construction duration. A shorter construction time means lower labour costs and lower expenses 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). ree 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. e 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/m 2 K), thus allowing a reliable comparative study.

Post occupancy evaluation of housing reconstruction after cyclone sidr

“…Houses constructed with locally derived materials are suggested by housing experts. In the study area; clay, straw, bamboo and sand are readily available and need no special treatment (Drozd et al 2018) to use in construction. Bamboo mat is commonly used as wall material-al in the houses and organic materials (such as jute sticks and catkin grass) are conventionally popular to use as wall material.…”

Method of Construction Projects’ Classification for Habitat Assessment in Poland and the Problem of Choosing Materials Solutions

“…Environmentally-friendly materials are still poorly known and not much popularised, especially in Poland. One possible reason for this situation is that in the 21-st century, there are efforts made to employ advanced building technologies while the potential of simple ones is not seen [51,52].…”

Ecological Wall Systems as an Element of Sustainable Development—Cost Issues

“…The article is a continuation of a research study carried out by its authors in this subject matter. In reference [7], they have presented a comparative study of these walls regarding construction time. In this article the intended purpose has been to show a comparative study for the same walls regarding their construction costs.…”

“…In reference [5], the authors proved that the results of developing sustainable architecture are based on changing the function of a building from a linear approach to a closed circulation plan, where a building can evolve from a consumer of energy and other resources into a virtually self-sufficient unit. Investors include green aspects in their construction projects more frequently [5][6][7]. They increasingly desire natural buildings where special attention is paid to the use of ecological materials (such as straw, wood, and clay), energy saving during the building process, and the health of residents.…”
