Abstract
The present study investigates the optimization of the sustainability characteristics of an innovative masonry wall system. The proposed construction technology is based on the use of modular load-bearing masonry units that can accommodate thermal insulation materials either embedded within their core or attached as external leaves on their face. The present study investigates alternative geometric configurations of the masonry system, in order to further improve its overall performance. The investigation aims to find the optimal geometry in terms of thermal performance, structural integrity and ergonomics. Following the selection of the optimum solution, alternative scenarios for the use of insulation were investigated in order to further improve the thermal performance of the selected geometry. Based on the findings, a significant improvement of the thermal performance and ergonomics can be obtained from the creation of rows of voids, without significantly compromising the compressive strength of the units. Also, further improvement of the overall thermal performance can be obtained with the proper use of insulation, without posing a significant burden on the environmental impact of the end-product.
