Artificial Intelligence in Architectural Heritage Conservation: Methods, Applications, and Future Directions

 

Architectural heritage is characterized by complex structural systems, long-term material aging, and evolving usage patterns, which result in diverse and often unpredictable damage mechanisms. These challenges are further compounded by external environmental factors that are difficult to control, increasing uncertainty in conservation efforts. This study positions artificial intelligence (AI) as a transformative tool capable of addressing these complexities by enabling data-driven, adaptive, and efficient heritage protection strategies.

Characteristics and Challenges of Architectural Heritage Protection

The paper highlights how architectural heritage differs fundamentally from contemporary buildings in terms of materials, construction techniques, and vulnerability to environmental stressors. Damage patterns in heritage structures often develop slowly and nonlinearly, making early detection and intervention difficult. These characteristics necessitate advanced analytical tools that can handle uncertainty, heterogeneity, and long-term monitoring, forming a strong rationale for AI-based approaches.

AI Applications Across Key Conservation Phases

This review systematically categorizes AI applications according to the main phases of heritage conservation: structural and environmental monitoring, damage identification and detection, environmental condition prediction, deterioration risk assessment, and environmental control. For each phase, the paper explains how AI enhances decision-making by improving accuracy, responsiveness, and predictive capability compared to traditional methods.

Machine Learning and Deep Learning Methodologies

A core contribution of the study is its detailed discussion of AI methodologies used in heritage conservation, with particular emphasis on machine learning and deep learning algorithms. These techniques are examined in relation to tasks such as image-based damage recognition, sensor data interpretation, and pattern extraction from high-dimensional datasets. Recent advancements demonstrate AI’s growing effectiveness in handling complex conservation scenarios.

Limitations of Current Research and Technical Constraints

Despite notable progress, the paper identifies several limitations in existing studies, including data scarcity, lack of standardized datasets, model generalization issues, and challenges in interpretability. Practical constraints related to sensor deployment, computational resources, and interdisciplinary collaboration are also discussed, highlighting barriers to large-scale and long-term implementation.

Future Directions and Integration Pathways

The study concludes by outlining future research directions aimed at deeper integration of AI and architectural heritage conservation. These include the development of hybrid models combining physical knowledge and data-driven learning, improved data-sharing frameworks, explainable AI approaches, and closer collaboration between conservation experts and AI researchers. Such advances are expected to support more sustainable, proactive, and resilient heritage protection strategies.
