Philadelphia House is a refurbished commercial office building located along Moi Avenue in Nairobi’s CBD. Originally built in the mid-20th century, the building underwent a comprehensive retrofit, including full upgrades of electrical, mechanical, and plumbing systems. UGC was engaged to guide the project team through a sustainability strategy that met the EDGE standard, focusing on energy and water efficiency while preserving the building’s original structural elements. This project serves as a powerful demonstration of how older buildings can be modernised to meet international green building standards without the need for complete reconstruction.
