Adaptive Reuse of Heritage Structures through Sustainable Architectural and Structural Interventions

Abstract

The preservation of architectural heritage faces an urgent imperative to align historical conservation with modern environmental sustainability, structural safety, and socio-economic functionality. Adaptive reuse—the strategy of repurposing disused or underutilized historical structures for contemporary functions—offers a robust framework to mitigate urban sprawl, minimize embodied carbon, and preserve cultural identity. However, executing adaptive reuse interventions without compromising structural integrity or authentic heritage value requires a delicate equilibrium between architectural design, material science, and structural engineering. This review paper provides a comprehensive evaluation of sustainable architectural and structural intervention methodologies applied to heritage conservation. By synthesizing recent literature and multi-disciplinary case studies, this paper examines non-destructive evaluation (NDE) techniques, reversible structural retrofitting (e.g., Fiber-Reinforced Polymers, lime-based grouting, steel bracing), and passive architectural environmental control mechanisms. Furthermore, we quantitatively analyze environmental lifecycle performance, embodied energy conservation, operational thermal optimization, and seismic resilience enhancement. Critical implementation challenges including regulatory compliance, material incompatibility, moisture dynamic alterations, and economic viability are thoroughly evaluated. Finally, this paper provides strategic design guidelines and identifies future research opportunities to advance intelligent, circular, and climate-resilient heritage conservation practices.  KEYWORDS: Adaptive Reuse, Architectural Heritage, Structural Interventions, Sustainable Conservation, Non-Destructive Testing, EmbodiedCarbon, Reversibility.
