Cost-effective and energy-efficient building using the rammed earth technique in south east Nigeria: Challenges and prospects

Abstract

As global concerns about sustainability and energy efficiency in construction grow, the rammed earth building technique presents a compelling option. This traditional method of building, practised widely traditionally in the past in the South East of Nigeria in the form of cob, is known for its low environmental impact and cost-effectiveness. Rammed earth building is experiencing a renaissance in modern architecture. This article examines the economic and energy benefits of rammed earth construction, its challenges, and future prospects. By addressing technical, regulatory, and perceptual barriers, we explore how this ancient technique can meet contemporary demands for sustainable building solutions in the region.
