Good Leads the Way; A Headquarters' Decarbonization Journey

The renovation and restack of 13 floors at the United Airlines headquarters in Chicago created a hybrid workplace infused with a dynamic energy that reinforces employee pride. This space brings together staff through shared experiences connected to United's brand story: an airline where Good Leads the Way. Re-use and revitalization of the existing space was a priority to align with United's sustainability goals. Circular design strategies were implemented, creating a next-life in lieu of an end-life for many of the tenant improvement materials and furniture. After optimizing reuse, new FF&E specifications included criteria for recycled content, material and occupant health, yielding a significant embodied carbon reduction of over 3,000 metric tons of CO2e emissions. This large-scale project case study demonstrates how circular design/economy strategies can be incorporated to deliver successful next-generation workplace environments while having a positive impact on people and planet.
