Energy efficiency applied to vernacular architecture, case of the rammed earth buildings: A literature review

Abstract. Rammed earth architecture is a widely spread vernacular architecture on a global scale and represents an iconic construction model in our country. Indeed, this architecture is an integral component of Moroccan architectural heritage. Long neglected in Favor of modern construction techniques, this method is nowadays experiencing a renaissance due to its energy, environmental, socio-economic, and aesthetic qualities. However, although its aesthetic and historical value is well-established, its energy, ecological, and environmental aspects deserve further exploration. This article aims to shed light on these aspects by placing them within the current energy trend, through the study of the thermal characteristics of the construction material and the analysis of the conceptual choices of rammed earth architecture in Morocco.
