EDGE Version 3.0 is live!

The Cube has been gratned an EDGE Advanced Preliminary Certificate from Green Business Certification Inc. (GBCI).

The Cube

The CUBE


The Cube is a commercial complex located in Nairobi, Kenya with a striking full glass façade and cantilevered roof over an open outdoor space.

The project tackled sustainability in the early phases of the project by carrying out building simulation modeling to assess daylighting, glare and ventilation impacts to optimize the building performance.

Given the large amount of glass desired by the designers, extra focus was given to lighting efficiency, high performance glazing and solar PV. Ultra-efficient water fixtures were used to minimize water consumption proving how significant and impact this initiative can make. Beyond EDGE the building will have a large focus on sustainable waste management.

The Promenade

The Promenade


The Promenade is a multi-tenant commercial office building in the Westlands area of Nairobi. The seven-story building offers high quality office and retail accommodation for tenants looking for a sustainable and flexible working environment. Tenants also enjoy the building’s generous balconies and breakout areas, which provide space for relaxation and provide an opportunity to connect with the surrounding landscape.

The commercial building utilizes resource-efficient design features and technologies to reduce its environmental impact and lower its operating costs. Higher thermal performance glass, LED lighting, and occupancy sensors were installed to reduce the building’s energy use, while low-flow and water-efficient plumbing fixtures were installed to reduce the building’s water use.

The building’s developer, Krystal Investment Ltd, was committed to improving the resource efficiency of the Promenade, especially regarding the building’s water usage. As the water demand in Nairobi has skyrocketed due to ever increasing modernization and construction in the city, a water-efficient building has become essential. The building was also designed by Symbion architects and constructed by Parbat Seyani.

The Promenade has received final EDGE certification from GBCI.
