Purple Tower

Purple Tower

Purple Tower is a 62m-high, mixed-use development located along Mombasa Road, in Nairobi, Kenya. The building will include a total of 3 floors of retail space and 12 floors of office space.

The project was developed by Purple Dot International, a local real estate development company which seeks to integrate green building thinking into all future projects. Beyond EDGE, the project is committed to additional sustainability initiatives such as operational waste recycling.

To meet international standards for resource efficiency, energy and water-saving technologies were incorporated into the design, construction and internal processes of the building. Higher thermal performance glass, energy-saving lighting equipped with occupancy sensors, and solar photovoltaics reduce the building’s energy use, while water-efficient plumbing fixtures reduce its water use.

Purple Tower has received a Preliminary EDGE Certificate from Green Business Certification Inc. (GBCI).
