Food security in hyper-arid regions is constrained not only by water scarcity and soil degradation but by the thermodynamic instability of agricultural climates. In countries such as Qatar and across the Middle East and North Africa (MENA), extreme diurnal heat loads impose continuous cooling demand on controlled-environment agriculture, rendering food production energy-intensive and economically vulnerable. This study presents a novel multi-layered wall (MLW) designed to establish a controlled microclimate within interior agricultural environments under arid conditions. It is an arrangement of thermally useful materials: a high-thermal-mass clay composite for conductive attenuation; sequential semi-permeable membranes to interrupt and regulate convective exchange; a conditioned cavity that uses stack-driven airflow together with embedded cooling system; a concrete layer providing structural endurance and secondary buffering; and a recycled-plastic insulation layer to reduce residual flux. The assembly sequences moderate resistances and storage capacity to produce thermal lag, flux dispersion, and amplitude damping. Laboratory experiments under controlled radiative loading and sustained heat exposure verify the hypothesis: the MLW suppresses peak internal temperature excursions, flattens thermal gradients across interfaces, and preserves near-baseline interior conditions over prolonged forcing. Energy accounting for indoor farming loads suggests meaningful reductions in cooling demand when MLW-mediated temperature control replaces part of traditional mechanical conditioning.
