Abstract [en]

In this paper it is attempted to investigate the Leca blocks as sustainable construction material forthe exterior walls of passive house. The building physical properties of Leca design wall structureare studied along with the environmental impact and load-bearing capacity. To compare the results,a similar analysis is carried out considering the traditional wooden wall construction of passivehouses. The results showed that Leca design wall structure can be an alternative sustainablesolution to the traditional wooden wall structure of passive house, mainly due to its low U-value,its ability to handle moisture, and comparable structural load-bearing capacity. However, thewooden wall structure is more environmentally friendly than the Leca blocks due to its loweremissions to the environment and reduced energy use, especially during the manufacturing process.
