This research is intended to provide information on the need to replace high-energy building materials and practices with energy-efficient materials and technology for sustainable housing development. This paper presents a material produced from corn cob ash and kenaf fiber proposed as an energy-efficient building material. Little or no energy was utilized in its production and utilization. The paper presents a discussion on locally available and sustainable raw building materials, such as corn cob, coir, palm kernel shells, bamboo, and their ashes. The material used was locally obtained; they are corn cob, kenaf fiber, ordinary Portland cement, quarry dust, and potable water. The corn cob ash was obtained by air drying corn cob and burning it in a furnace at 650◦C to produce carbon-free ash. The equipment used was also locally fabricated. Pictures showing the application of these materials and equipment are also showcased. Findings of this study could be used to reduce the total amount of energy used in the provision of building services and products.
