Sustainable housing in island conditions using Alker-gypsum-stabilized earth: A case study from northern Cyprus

Abstract

Abstract The materials and energy sources needed for construction are limited by island conditions. Until recent decades, earth was widely used as a construction material in northern Cyprus due to its abundance and many technical advantages, however, as a construction material, earth is vulnerable to moisture. Ongoing research into gypsum-stabilized earth (known as Alker) at Istanbul Technical University since 1978 demonstrates the superior physical properties, increased durability, and human health benefits of this improved earthen material. This study examines the use of Alker as a wall material to contribute to sustainable development in Northern Cyprus. The historical building materials and environmental resources of Cyprus are investigated and documented to gain an idea of what is involved in the socio-cultural, economical, and ecological sustainability.
