Nairobi’s skyline is changing — not just with height, but with purpose. Across the city, developers and building owners are discovering that retrofitting existing buildings with sustainable systems isn’t just good for the planet — it’s great for business.

Retrofitting means upgrading older buildings with energy-efficient lighting, better insulation, water-saving plumbing, and renewable energy solutions like rooftop solar.
According to the Kenya Green Building Society (KGBS), green-certified buildings in Nairobi enjoy up to 25–35% lower energy use and higher tenant satisfaction.
Beyond energy savings, green retrofits also help properties qualify for green financing, making sustainability financially rewarding.
Example:
One Nairobi office block reduced its electricity bill by 30% after replacing outdated air conditioning with an EDGE-certified HVAC system. The project’s payback period? Just under 3 years — with improved asset value.
