Next-generation building envelopes: Smart materials, energy efficiency and environmental impact
(Elsevier B.V., 2025) Barbhuiya, S.; Das, B.B.; Adak, D.; Rajput, A.
Building envelopes play a crucial role in enhancing the energy efficiency, sustainability, and overall performance of modern buildings. This paper provides a comprehensive review of cutting-edge materials and technologies for smart and sustainable building envelopes. It highlights the transition from traditional to advanced materials, focusing on the integration of smart materials such as thermochromic and electrochromic systems, shape memory alloys, and self-healing materials. These innovations enable dynamic responses to environmental changes, enhancing comfort and energy efficiency. Additionally, the review explores sustainable materials, including natural, biodegradable insulation, recycled components, and low-carbon alternatives that contribute to the circular economy. Advanced insulation technologies such as vacuum insulation panels, phase change materials, and aerogels are discussed, emphasizing their superior thermal performance. The study also examines innovative facade solutions, such as adaptive facades, photovoltaic-integrated systems, and hybrid designs that merge sustainability with energy generation. Key challenges in adopting these materials—such as cost, regulatory compliance, and market readiness—are discussed, along with the environmental benefits, including energy savings and reduced carbon footprints. The paper concludes by identifying opportunities for future research and development in smart and sustainable building envelopes, highlighting their potential in advancing energy-efficient, climate-responsive architecture. © 2025 The Authors
Structural performance and implementation challenges of next-generation concrete materials
(Elsevier Ltd, 2025) Barbhuiya, S.; Das, B.B.; Rajput, A.; Katare, V.; Das, A.K.
Conventional concrete faces limitations in durability, sustainability, and adaptability to modern structural demands, constraining its use in high-rise, bridge, and extreme-environment applications. This study examines emerging concrete mixes—HPC, UHPC, SCC, FRC, GPC, and 3D-Printed Concrete—by evaluating their mechanical properties, implementation challenges, and future opportunities. A review of experimental data, case studies, and comparative analyses was conducted to assess strength, durability, workability, and structural applications. Results show that HPC and UHPC reach compressive strengths of 60–200 MPa, GPC achieves 40–80 MPa with reduced CO₂ emissions, SCC demonstrates slump flows of 600–800 mm, and fibre reinforcement enhances tensile strength to 8–15 MPa. These findings highlight superior performance, sustainability, and constructability, though high costs, lack of standards, and scalability issues remain obstacles to widespread adoption. This review uniquely integrates comparative insights on High-Performance, Ultra-High-Performance, Self-Compacting, Fibre-Reinforced, Geopolymer, and 3D-Printed concretes, bridging laboratory findings with real-world applications. Unlike existing reviews, it emphasizes structural implementation challenges and opportunities. Key obstacles—including high cost, lack of standards, and scalability—are outlined to contextualize pathways for sustainable adoption. Overall, next-generation concretes deliver enhanced strength, durability, and sustainability, making them viable for critical infrastructure. Future studies should focus on advancing standardization, integrating nanotechnology and AI for mix optimization, and developing cost-effective, large-scale deployment strategies. © 2025 The Authors
