Biodiversity and natural areas

The green frame

  • Ecological continuity are based on several elements of the landscape:
    • city ​​park: better integration of the operation in the mid-slopes
    • 3 northbound green corridors crisscrossing troughs corresponding to the site
  • The sanitation facilities are decomposed into multiple pools and terraces of sizes and shapes
  • These basins hinder water densely planted rains, marked by low walls and riprap
  • Urban park, pathway space, green areas, combine the ecological, economic and social
  • Integration of local sectors in order to promote the economy of Reunion of Works and limit imports (basalt, endemic plants ...)
  • Choice primarily basalt (covering, wall) produces locally for public spaces (courts of CAF, squares, pedestrian crossings ...)
  • The Beauséjour landscape project is based on the geography of the site, with the water as a conductor pattern wire

  • Valuation of endemic and indigenous flora along the walking areas and paths:

    • For opaque: 14,000 endemic / native and exotic 14000

    • For trees and shrubs: 13,000 endemic / native and 500 exotic


    • Management of natural areas

Climate adaptation, resources conservation, GHG emissions

  • Integrating ventilators instead of air conditioning
  • Solar hot water
  • An electric bike for free by acquiring a residence
  • Screen shade on the most exposed facades
  • Use of Trespa and ondulite sheet on the facades to ensure a comfortable temperature
  • External joinery to privilege natural ventilation 

Energy sobriety

  • The choice of LED on all project to control consumption

  • Restrictions on range of street lighting furniture in Beauséjour: meets the environmental objectives of the project, higher optical performance to 70%, less than 5% of the luminous flux directed towards the upper hemisphere (ULOR)

  • Variation in intensity and color during the night


    • Urban Lighting


Built to bioclimatic principles:

  • Buildings are vegetated surroundings, providing shade and freshness.
  • Sun protection (roofs, facades and windows) and natural ventilation shutters (or classic opening) front.
  • Façades exposed to strong winds of trade winds (East and Southeast) have a wind shield

Energy management :

  • No air conditioning. The projects have many openings to the outside in order to promote natural, cross ventilation and natural lighting.
  • Artificial lighting will be achieved by efficient lighting (compact fluorescent lamps, fluorescent, LED), the number and distribution of lighting will be optimized to minimize power consumption while maintaining satisfactory illumination of premises.
  • Use of solar energy for hot water.
  • Energy-saving lamps in public areas
Water Management :
  • Car parking lots are arranged primarily within buildings and internal service channels are downmixed to limit the outer surfaces waterproofed
  • Prioritize specific mechanisms of infiltration and delay stormwater (ditches, swales, riprap) are arranged to facilitate the penetration of rainwater into the soil of the plot.

Choice of construction processes and products:

  • Riprap, infiltration devices and rubble walls will be carried out primarily with the rock cuttings from the site excavations and earthworks.
  • Use of wood for structural reported structures (walkways, roofs, poles) for decks and sun protection is preferred.
  • Protection of exposed cladding facades
  • Some elements of protection to the wind and sun (double skin facade East, West facade sliding panels) will be made of PVC coated polyester fabrics of micro-perforated
  • Integration across all markets award to respect a "clean worksite charter"
Establishment of an environmental coordination of work
