Kigamboni Housing Estate

First Green-Mark Certified Affordable Housing in Kigamboni Estate

Kigamboni Housing Estate

Building a resilient community for 190 sustainable and affordable homes in Dar Es Salaam for African cities to model after.

Working with the National Housing Corporation (NHC) of Tanzania, GreenA Consultants worked on this project which might possibly be the first green certified affordable housing estate in Africa. This affordable sustainable housing project in Dar es Salaam consists of 190 units.

Green homes are built with people in mind. They maximize the use of natural energy and decrease the consumption of non-renewable energy, thus, reducing carbon footprint.

This passive design for the houses were designed for the people in mind, without the need for expensive cooling technologies. Passive features reduces its dependency on energy without compromising comfort and performance.

Program Breakdown:

187 Landed Houses (80 sq. or 130 sq)
Clinic (316 sq)
Kindergarten
Nursery School (1500 m2)

“Sustainability is not limited to those who have the money nor does it require elaborate technology.
It does however, need a level of education and expertise to facilitate the energy efficiency efforts.”
– Farizan d’Avezac de Moran

Training Locals in Energy Efficiency & Green Building Techniques

All the works of the houses are done by locals therefore spreading knowledge and skills throughout. There is a local training centre to train workers on trades including carpentry, plumbing as well as construction of walls using hydraform.

Other than improving skills for future employment opportunities, this project is also developed to be socially inclusive. The development aims to redefine the vision for affordable housing. With an emphasis on the flexibility and liveability of a space.

Some of the passive design strategies used.

Minimize West and East facing façade to lessen sun exposure.
Openings facing prevailing wind direction.
Daylighting Fenestration
Pitch roof design with air gap and perforation in the roof cavity provides and inexpensive method of direct solar radiation protection.
Orientation of the houses are designed in such a way that the inter-blocking of winds are reduced.
Natural ventilated with fan points and with good cross ventilation. Apparent shading is only at the front porch of the house.
Feature homes with outdoor kitchen to promote natural ventilation in wet areas of the home. By placing the kitchen outdoors, ambient temperatures and indoor air quality are maintained.
A spacious garden at the back of houses can also enhance the extraction of hot air.
A CFD Analysis was conducted in the pre-design to enhance the opening configuration and to verify the appropriate air renovation rates.
