The document presents a business case for a proposed upgrade to the Chamberlain building at the University of Queensland. The project aims to retrofit the existing building by installing a new dynamic facade and upgrading the internal spaces. This will enhance the building's sustainability, reduce energy costs, and improve the learning environment. Three upgrade options were considered: doing nothing; installing just a new facade; or a full retrofit of both the facade and internal spaces. A full retrofit was determined to best meet the evaluation criteria of enhancing the university's reputation, being cost effective in the long run, improving teaching and learning, managing time well, minimizing disruption, staying on budget, ensuring quality, and fitting with the surrounding context aesthetically.
