Located in the neighbourhood of ‘Ravine Blanche’, in Saint-Pierre, Niama is a social housing operation that includes 19 units. The building is closed to a new urban park, both part of an urban renewal program that aims at restructuring the neighborhood and connecting it to the city center. Ravine Blanche is the only neighborhood that awarded the french 'EcoQuartier' certification in the tropics among 32 other projects in 2013. This existing neighbourhood already received in 2010 a local distinction for its innovative approach.
The building includes passive features such as cross natural ventilation and solar shading devices so as to enhance thermal comfort while reducing energy consumption.
Sustainable development approach of the project owner
Located in the neighbourhood of ‘Ravine Blanche’, in Saint-Pierre, ‘Niama’ is a new social housing operation that was completed in the end of the year 2014. Niama is compliant with the Thermal, Acoustic and Ventilation French Regulation for the overseas territories (in French: Réglementation Thermique, Acoustique et Aération or RTAA DOM). RTAADOM is applied to the design of new residential buildings only and requires mandatory rules concerning thermal, acoustic and ventilation performances. The objectives of the project were to house people at low-level income inside comfortable apartments. As a result, Niama uses many passive design strategies in order to reduce its energy consumption while maintaining satisfactory thermal comfort conditions inside the building. The building was also designed so as to be integrated within its environment.Architectural description
Niama has been designed and built on the basis of local climate and resources, for energy (sun) and materials. Passive features such as building orientation, natural cross ventilation or the choice of construction materials such as wood, have been taken into account. Since the effects ofvegetation on a site's microclimate can be considerable, the building is surrounded by native plants and trees.
In addition, the park and the building include features for the integrated management of rainwater , such as a serie of landscaped ditches and basins, the design of a path allowing the natural flow of rainwater, as well as the consideration of soil permeability and the type of covering materials.
If you had to do it again?
Each apartment has its own parking space. However, the actual rate of use is approximately of only 30%. The related area could have been used for vegetation or other common areas.

The roof is composed of an insulated sheet metal complex "Mauka Brizz" (from ArcelorMittal) and 13mm of plasterboard.
For the solar exposed walls, the materials used from the exterior to the interior are listed below:
First floor: 18cm of concrete + 2cm of expanded polystyrene + air gap of 0,5 cm + 1,3 cm of plasterboard
Last floor:2cm of wood + 3cm of expanded polystyrene + air gap of 10cm + 1,3 cm of plasterboard
Other floors: Insulated sheet metal complex Mauka Brizz (ArcelorMittal)+ 18cm of concrete
Each floor is composed of different materials according to the facade orientation and the sun exposure.
This product was well accepted by the different stakeholders of the project.
