Expo 2020 – Sustainability Pavilion

Project Summary

The Sustainability Pavilion is one of the signature pavilions’ trilogy for Expo 2020. It aims to demonstrate the possibility of how architecture and built environment gives the possibility of a new way of a sustainable living. The pavilion design draws inspiration from the complex natural process of photosynthesis by capturing energy from the sunlight and freshwater from air humidity.

Grankraft fabricated and installed the weathered steel screens that form the perimeter walls of the central courtyard of the pavilion which are sunken into the ground. Based on thermodynamic studies, the Corten wall is angled in such a way that it channels desirable prevailing wind directions as part of the ventilation strategy, aiding the passive cooling of the space.

The exhibition spaces are surrounding the courtyard behind the  wall made of weathered steel. The overall area of the weathered steel is over 2000 m² and consists of more than 100 individual panels. Each panel features a unique linear design which, when assembled, forms a continuous pattern that extends across the entire courtyard. Each panel is 10m high and 2m wide and the pattern was laser cut into the weathered steel panels which are hooked to a mild steel support structure.
