Abstract

In Iran’s hot and arid climate, the development of agricultural societies has historically depended on the ability to store grain for long periods without relying on energy-intensive systems. This study investigates the passive environmental strategies employed in the adobe silos of the ancient Saryazd grain storehouse. The research aims to identify indigenous grain-storage knowledge that can support the adaptive reuse and economic revitalisation of the Saryazd citadel, while also informing sustainable approaches in contemporary architecture. A descriptive–analytical methodology was adopted, combining computational simulations, documentary research, and interviews with eyewitnesses conducted during field surveys in July and August 2024. The results indicate that thick adobe walls, thatch roofing, hierarchical spatial organisation, narrow and nested corridors, and chimney-driven airflow together create favourable storage conditions. Computational analyses show that these strategies achieve an internal temperature reduction of 15–20°C compared to outdoor conditions and provide effective ventilation of approximately 0.7 CFM per ton of grain, ensuring grain health and longevity for decades. The study highlights the value of documenting and reassessing indigenous passive solutions as low-cost, efficient models for addressing contemporary challenges in climate-responsive and sustainable architecture.
