Calatrava combines energy consciousness with architecture for UAE Pavilion

Spanning across an area of 15,000 square meters (about 161,500 square feet), the UAE Pavilion at EXPO 2020, designed by renowned architect and engineer Dr. Santiago Calatrava, offers a symbolic interpretation of the flow of movement. Through the articulation of carefully planned lines and crafted spaces, the UAE Pavilion serves as a national monument and an iconic destination, creating immersive experiences for guests to discover the UAE’s rich history and dynamic future.

From the first sketch to execution, Calatrava designed the UAE Pavilion to harmoniously mesh with its interactive surrounding landscape, drawing visitors towards the shaded arcade wrapping along the perimeter wall and nestled beneath the floating and movable wings, that make up the Pavilion’s roof.

Structural inspiration: Wings that depict the flow of movement

The roof structure of the UAE Pavilion displays a hybrid system between a shell and a portal frame, composed of 28 wings. The wings can be opened within 3 minutes, completing a range of movements, between 110 and 125 degrees. The rotation of the wings is driven by a total number of 46 specialized and synchronized hydraulic actuators, functioning as pistons. When they are activated, hydraulic oil is pushed through the actuators, extending the pistons, and opening the wings to their full capacity.

The energy-conscious elements and photovoltaic panels at the UAE Pavilion

“We are committed to ensure that the leading practices of environmental sustainability are embedded at the heart of the design process,” shares Calatrava. “Accordingly, the UAE Pavilion is energy-conscious and integrates a range of elements and qualities of sustainable design, ensuring the longevity of the structure, to withstand the test of time,” he adds.

Sustainable elements, such as photovoltaic (PV) panels that have been produced in the UAE, have been integrated into the roof structure bringing the entire building to life with the opening of the wings. Beyond the notion of aesthetics, the wings shelter and protect a composition of curved and straight PV panels when they are closed from rain and sandstorms, and upon opening up, the panels are able to absorb as much sunlight as possible to harvest energy which is returned to the main power grid.

The UAE Pavilion has been designed and built to meet LEED Platinum Certification (based on LEED 2009 standards for New Construction). In addition, respecting ecological limits and natural resource constraints, it will also be compliant with the Dubai Green Building Regulations and Specifications (DGBR).

The Oculus – An architectural feature

The Oculus skylight at the apex of the roof of the UAE Pavilion mirrors the form of the Expo 2020 logo and is a fixed insulated glazing unit system, with a diameter of 12 meters, placing the UAE Pavilion at a height of 27.8 meters (91 feet). As an architectural feature that offers a skylight opening, the Oculus also has a functional quality where its surrounding grilles open for smoke extraction (in case of an accidental fire).

An Auditorium at the core of the UAE Pavilion

At the heart of the UAE Pavilion is a faceted sphere with an outer diameter of approximately 25 meters (82 feet) and an overall height of approximately 20 meters (65.5 feet) which houses an Auditorium. A specialized lifting platform supports the interior seating of the Auditorium and transports the audience from one floor to another while experiencing audiovisual shows.

The Auditorium serves as both a centerpiece and a functional space with a capacity that accommodates 200 people.

A close collaboration between father and son, for the UAE Pavilion

Collaborating to envision and complete the UAE Pavilion, Dr. Calatrava and his son, Micael, who is based in the UAE, work closely together.

“We shared similar visions with the stakeholders involved, and many suggestions that were brought to the table were deciphered and integrated to the overall design. This heightened the diversity of viewpoints in the creative process, allowing us to push the limits and challenge one another, to ensure that every angle, line and detail was accounted for and that the result is the best it can be, both for our client and for the visitors of the UAE Pavilion,” shares Micael.

With a growing office in the UAE, the Calatrava team believe that close proximity to the country and the client allows for the channeling of the true intended nature of the project from the first sketch.

“Our design process is similar to a journey that continuously unfolds with every sketch. Every creative journey we embark on, is unique for us, and this is demonstrated through the diverse portfolio of our architecture and design practice. Each project draws inspiration from the neighboring urban fabric from which it rises, to serve as an extension of the cosmopolitan city, as we have done with the UAE Pavilion,” he shares.
