Last year, GEOEG and enerdrape have been selected to showcase a project at the Thematic Exhibition of the forthcoming 2021 Seoul Biennale of Architecture and Urbanism (SBAU). After a year of work, this project will soon be exhibited at the SBAU in Seoul, South Korea – in exactly 10 days from now!

41’000 m2 de dalles énergétiques, 18’000 m2 de murs énergétiques and 1’382 m de pieux énergétiques

The various layers beneath Chicago and the vision proposed by GEOEG + enerdrape. The historic images of the freight and trolley tunnels are courtesy of Mr. Bruce Moffat, author of the historical book “40 feet below.”
About the project: As one of the densest American cities, Chicago suffers from torrid summers and freezing winters. Greatly as a result of this climate, the city has tremendous thermal energy requirements, which currently contribute to 71% of the citywide CO2 emissions due to reliance on non-renewable energy sources. Such emissions cause global warming, requiring a paradigm shift to avert catastrophic results of climate change.
The underground offers Chicago and all cities worldwide two critical attributes: energy supply resilience because it provides renewable geothermal energy for space conditioning and hot water production, continuously and irrespective of the weather, and environmental resilience because conditions underground are protected against extreme weather.
This installation reproduces an energy tunnel beneath Chicago that dynamically harvests heat from the ground and the people passing therein to power the city. Starting from tomorrow, this visionary urban intervention proposed for Chicago may disrupt many other cities across the globe. Examples of energy geostructures such as tunnels developed by GEOEG can be found in our projects and are also described on their dedicated webpage.
About the team: This project has been possible thanks to the contributions of a diverse group of people, including scientists, engineers, designers, and architects – the essence of GEOEG and enerdrape. Meet them below!

This project has been developed in collaboration with Carlo Gaffoglio Design and is supported by BDA Design, Swiss Korea Fund, the Swiss Embassy in Korea, and the Office for Economic Affairs and Innovation of the Vaud Canton.
