MVRDV’s “SOMBRA” pavilion is a compelling architectural experiment that explores dynamic shading and climate-responsive design using purely passive physical principles.

Unveiled at the European Cultural Centre’s Giardini Marinaressa in Venice for the “Time Space Existence” exhibition in 2025, SOMBRA is a portmanteau of the Latin words “sol” (sun) and “umbra” (shade), perfectly encapsulating its function.

SOMBRA is not just a temporary installation; it’s a demonstration and a prototype for a new kind of architecture that harmonizes with its environment, offering scalable solutions for climate-responsive buildings in the future. After its exhibition in Venice, there are plans for the pavilion to tour globally.

MVRDV’s “SOMBRA” pavilion is a compelling architectural experiment that explores dynamic shading and climate-responsive design using purely passive physical principles. Unveiled at the European Cultural Centre’s Giardini Marinaressa in Venice for the “Time Space Existence” exhibition in 2025, SOMBRA is a portmanteau of the Latin words “sol” (sun) and “umbra” (shade), perfectly encapsulating its function.

Key Features and Principles:

• Passive Kinetic System: SOMBRA stands out because it operates without any electronics or motors. Its kinetic shading system is driven entirely by natural physical principles. Small air canisters within the structure’s ribs expand when heated by direct sunlight, inflating airbags that act like muscles to close hinged, triangular panels. When the sun recedes and the structure cools, the air contracts, and the panels open again. This mechanism is inspired by the principles of soft robotics.
• Climate Responsiveness: The pavilion is designed to react dynamically to sunlight, providing shade when needed and opening up during cloudy periods or when not in use. This “breathing” quality makes it akin to a living organism, sensing and adapting to its environment.
• Sustainable Design: In line with its climate-friendly approach, SOMBRA is constructed with sustainability in mind. Its arches are made from reused beams from a previous project, and its operation has zero operational carbon emissions.
• Design Inspiration: The pavilion’s shape is inspired by heliodons, instruments used to simulate the sun’s path. Its six metal ribs are angled to correspond with the sun’s position during the summer and winter solstices.
• Symbolic Details: The circular floor plate features an engraving of the sun’s polar orbit, which dictated the pavilion’s geometry. Furthermore, the undersides of the arches are adorned with the words “sun and shade” in over 200 languages, emphasizing the universal human connection to these natural elements.
• Collaboration: SOMBRA is a result of a collaborative effort between MVRDV (architecture), Metadecor (panels, production), Airshade Technologies (patent holder for the air-driven system), Alumet (anodizing), Arup (mechanical engineering, sunlight studies), AMOLF Institute (research), Van Rossum Raadgevend Ingenieurs (structural engineering), and Kersten Europe (bending).
