Envelope performance

More information :

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

Heating system :

 98 m2 de photovolataque en attente de mise en place

Urban environment

• Land plot area : 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.

Product category : Structural work / Carpentry, cover, titghtness

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

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

Acoustic comfort :

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

• GHG in use : 24,00 KgCO₂/m²/an
Methodology used :

29 kWh / m² year of electricity with a Reunion mix at 0.820 kg CO2 / kWh

Life Cycle Analysis

Eco-design material :

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
