Abstract

The construction sector continues to face challenges associated with the durability, energy efficiency, environmental performance, and functionality of conventional building materials. Although nanotechnology has introduced materials with enhanced mechanical, thermal, optical, and chemical properties, their potential applications and future relevance to architecture remain insufficiently consolidated within architectural discourse. This study addressed the gap in knowledge by examining the prospects of nanomaterials as advanced materials for improving architectural performance and supporting the development of sustainable and responsive buildings. A systematic literature review was adopted, relevant peer-reviewed studies and theses were identified from major academic databases and analysed thematically based on nanomaterial properties, architectural applications, benefits, limitations, and future prospects. The review revealed that nanomaterials, such as nano-silica, titanium dioxide, carbon nanotubes, graphene-based materials, and nanoclays, have significant potential in concrete, coatings, glazing, insulation, façades, and composite materials. Their application can enhance strength, durability, thermal performance, energy efficiency, self-cleaning capacity, and environmental responsiveness. The findings further indicate opportunities for multifunctional and intelligent building components capable of responding to changing environmental conditions. However, high production costs, scalability, long-term performance, environmental implications, and health and safety concerns remain barriers to widespread adoption. The study concludes that nanomaterials offer considerable prospects for transforming architectural materials and advancing sustainable, durable, energy-efficient, and responsive buildings. Their successful integration, however, requires continued interdisciplinary research, life-cycle assessment, and the development of appropriate technical and safety standards.
