The structure uses passive environmental control to preserve the historical complex

An innovative project in Spain has managed to balance considerations around contemporary architecture, environmental needs and heritage conservation with a huge 3D printed and textile outdoor canopy.

The structure covers and protects an ancient tomb site at the Archaeological Complex of Carmona in Seville, southern Spain. PhD architects and Associate Professors from the University of Seville, Juan Carlos Gómez de Cózar and Manuel Ordóñez Martín, designed the reversible and recyclable cover.

The lightweight roof’s double membrane creates an intermediate air chamber which aids the movement of hot and cold air masses within the tomb complex. Passive conditioning strategies around light, air, and ventilation were all integrated into the design.

Close monitoring and management of airflow via ventilation and extraction components embedded in the roof also help ensure the preservation of the tombs through the stabilization of the conditions.

The canopy was designed to have minimal visual intrusion on the archaeological site, and rises to the bare minimum from ground level to create the necessary aforementioned airflow. The slender and reduced number of supports contributes to both the aesthetic and environmental effects.

Minimal material usage and rapid assembly were both prioritized in the project, and the roof’s reversible and recyclable properties mean that future removal and replacement align with the philosophy of a low-impact structure. Its environmental footprint target was also set at under 100.0 kg CO₂ equivalent.
