The new headquarters for car rental company Arval uses geothermal and solar energy to achieve complete self-sufficiency and zero-emission status. Pierattelli Architetture designed the building with huge photovoltaic steel wings lined with over 1000 flexible solar panels to maximize its energy-collecting capabilities.

The architects designed the headquarters, known as the Photovoltaic Bolt, as a Climate House Class A building without emissions. The complex is characterized by huge photovoltaic wings with about 1000 solar panels, realized with a steel frame. Together with the panels installed on the roof, these structures can generate enough power to activate the geothermal pumps in the subsoil and make the building completely energy self-sufficient.

The office spaces and common areas are distributed across 3 floors and a basement, accommodating about 200 employees per floor. Spaces are articulated around a central dorsal on a north-south axis to provide an east-west direction and guarantee optimum sunlight positioning.

Natural light is available throughout the complex. The architects placed ceiling lights of different dimensions to guarantee maximum diffused lighting capability. Large open spaces and colorful furniture help humanize the spaces and enhance socialization. Color coding by program makes navigation more intuitive and fun.
