Nobelia Tower construction project in Rwanda accorded Green Star rating

The proposed 19-storey Nobelia Tower construction project in Rwanda has been awarded a 6-Star Green Star building rating by the Green Building Council of Rwanda.

This comes after the completion of the final design of the planned 11 469 m2 building, making it the first Rwanda-based development to achieve the highest certification in green building standards.

The project owner, WSP Parsons Brinckerhoff, a multidisciplinary engineering firm was currently lobbying for funding to proceed with construction.

“We are very proud of the 6-Star rating achievement. At the beginning of the project, the owner’s brief was to produce a design that would set the bar for green buildings in the country and we have certainly done this,” said Eloshan Naicker, Green by Design sustainability consultant.

Eudes Kayumba of Green Building Council, Rwanda said that the building would be a model for future sustainable development.
During the commencement of the project, the Green Building Council of Rwanda was still at its infancy therefore a local context report had to be initiated in a bid to establish the groundwork for the Green Star and put in place the right standards for the climate and environment in Rwanda.

A significant amount of research and assessment was carried out by WSP Green by Design and submitted for assessment by the Green Building Council governing body during the process.

The process provided the Green by Design team with invaluable insights into the local setting which was significant to the project.

The project designers were able to offset the carbon emissions as part of innovative and sustainable features of the building.

The façade of the building additionally contained no glass and was made of a polycarbonate material mesh structure that allowed plants to grow beneath it.

“The main purpose is to make certain that vegetation could grow all over the mesh and create natural shading,” Naicker said.

The team also integrated air- conditioning system, ventilation and a sophisticated heating dehumidify the fresh air.

Meanwhile, a waste management system would be used to create compost adding to ecological value by improving soil, plant growth and biodiversity.

Light-emitting-diode fittings would be incorporated in all usable areas together with intuitive daylight sensors to detect how much natural light was available and compensate for the difference, as well as occupancy sensors.

In order to improve the quality of the indoor surrounding, recommendations were made that no ozone depleting products used in the construction of this building.

The building has generally achieved a high score for its energy performance potential during the design evaluation. All this is attributed to the reduced carbon footprint and carbon dioxide emissions that the design was able to achieve.


  1. This is encouraging to hear that more buildings are having green ratings in Africa. Nobody seemed to be talking green when I returned from my masters in renewable energy and architecture. Hope many more get constructed!
