Energy-intensive building

The media library of Saint-Joseph (Reunion) questions the identity of the contemporary architecture of Reunion, that of the Sud Sauvage more precisely. It refers to images , block of basalt, fagot of vetyver, geko, kalbanon but especially for uses , taking again the progressiveness of the sequences of traditional entries, creating a progression between the public space and that of the intimate one.
The building incorporates a direct relationship to the outside, blurring its limits with the interior. Only way to succeed, the design of an open building, passive, so without air conditioning. He achieves this by insulating, protecting himself from direct sunlight, by ventilating naturally and by adding a low-pressure chimney.

Envelope performance

    The indicators Ubat, compactness or airtightness are not applicable for a non-conditioned building in a tropical climate. Only count the sun protection of the porosity of the envelope to make natural refreshment
    Solar factor of bay windows: N 0,30 E 0,30 S 0,40 O 0,25
    Solar factor of opaque walls: 0.05
    solar factor of the roofs: 0,02
    porosity of facades: 30%

More information

Project delivered in December 2017 so waiting to return. The PREBAT program of the ADEME will allow a precise measurement.

Systems

    • No heating system
    • Solar Thermal
    • Tape
    • No cooling system
    • Natural ventilation
    • Solar Thermal
  • 70,00 %
  • ventilation et rafraîchissement entièrement passifs à l'exception d'un local serveur et d'un local fonds anciens

     98 m2 de photovolataque en attente de mise en place

Urban environment

  • 7 394,00 m2
  • The media library assumes its status as public equipment, it is now a signal in the heart of a city center, a meeting place especially for the youth of St. Joseph.
    The square is thus treated like a public place, terminals to sit down, an amphitheater taking place in bottom of scene, to wait or to attend the shows outside the walls of the media library.

    Gros œuvre / Charpente, couverture, étanchéité

    Green roof on the base and above the youth area

    Participates in the landscape of the floors, totally accepted by MOA

Water management

    65% of the water requirements of the sanitary systems fed by the recovery tank system

Indoor Air quality

    In any case, the air exchange rates required by the natural cooling are between 120 and 300 vol / h and evacuate in a few minutes any internal pollution.

Comfort

    inconfort selon la méthode de Givoni sur moins de 1 à 3% du temps selon les locaux

    The mismatch between natural ventilation and acoustics has been treated by multiplying the absorption devices in vertical and horizontal walls:

    • Acoustic wool between fishnet and floors
    • Perforated placo + absorbent
    • Wool of compressed wood in dressing
    • Acoustic baffles in ventilation shaft
    • Rubber floor for impact noise reduction

GHG emissions

  • 24,00 KgCO2/m2/an
  • 29 kWh / m² year of electricity with a Reunion mix at 0.820 kg CO2 / kWh

Life Cycle Analysis

    wood

    • wood structure on:

    - facades and roofs of the youth boxes (Mamothèque, story room, ...)

    - facades R + 1 of the administration building

    - façades R + 1 to R + 3 of the building Adults

    • Wooden cladding on facades R + 1 to R + 3 of the building Adults
    • Wooden shingles on roofs of youth boxes; wood cladding
    • Wood solar protection
    • Acoustic ceilings made of solid wood on the Vetiver building

Reasons for participating in the competition(s)

Passive building without air-conditioning functioning through ventilation through a low-pressure chimney. Protection of solar radiation and over-insulation. Light wooden facades to reduce the inertia of the walls. Water management by maximum permeability, establishment of green roofs and recovery of sanitary EP.
Contribution of the landscape as much in its relation to the interior / exterior space as for reducing the effect of overheating at the foot of the building.
