The San Sisto Aranciera is a monumental greenhouse designed by the architect Raffaele de Vico in 1926 for housing the Department of Environmental Protection plants.  

The redevelopment project aims to achieve structural consolidation and energy efficiency for the building. Technologies and targeted solutions will be applied in order to preserve its original appearance while making it a multifunctional space. 

The project will adopt passive energy strategies for climate control of the building, integrated with an innovative photovoltaic system, a geothermal system, an air purification system through plants, and a  water recovery and recycling system. The restoration of the Aranciera will thus become a virtuous and potentially reusable design model, even in other buildings owned by the Municipality of Rome.
