Energy-intensive building

The social landlord, New Logis Provencal, has achieved a complete rehabilitation of 190 housing in Orange Fourchevieilles neighborhood thanks to the funding program ADEME-Region ERDF.

The six constructions built in 1960, had a negative image because of their appearance and a number of technical problems. The NLP adopted then, an orverall response, in order to respond to 4 objectives:

  • reduce energy consumption to reduce rental costs;
  • change the image of the neighborhood by a complete transformation of the architecture allowed by the insulation of facades;
  • improve comfort through renovation of common areas and equipment;
  • enhance the attractiveness of housing.

These buildings are now reaching the level of thermal performance of the RT2012 (French certification), while providing quality architecture that completely transforms the perception of this neighborhood in the city.

Sustainable development approach of the project owner

The project is part of the rehabilitation of buildings C, D and E located in "rue du Bellay" and buildings A, B and G located in "rue Descartes" on the perimeter of Fourchevielles District in Orange.

Architectural description

Project management company highlighted the architecture of buildings with a complete redesign of the facades. This allows a simple reading of the buildings components and entrances. A game of superposition and offsets has been possible by varying the insulation thickness.

Urban environment

    The buildings are arranged along the streets with parking alignment, creating a certain urbanity. Playback of traffic and access to the buildings is simple. The project contributes to the diversity of housing in the municipality.

    - External Insulation system of expanded polystyrene, with multiple possible finishes. It is widespread and has been placed on nearly 400 million square meters of facades in the world. - Cladding PARKLEX S - TERREAL THERMOREAL GEBRIK Base papanels, hand molded appearance.

    The external insulation system, is a key element of the performance of this project. It helped make the building more comfortable without reducing the living space. The choice of cladding panels brings a contemporary look to the project that is much appreciated.

Construction and exploitation costs

  • 4 950 000

Reasons for participating in the competition(s)

The building obtained the Mediterranean Sustainable Building certification (BDM),bronze level, with a primary energy consumption (TPEC) of 53 kWh / m².year (a gain of 75 % compared to the TPEC 211 kWh / m².year). The intervention focused on the envelope and systems, including photovoltaic and solar thermal generation.

This project contributed to re-qualify this particularly disadvantaged neighbourhood. A consultation and a sensitizing program were conducted. Social insertion provisions enabled unemployed persons from the neighbourhood to work during the construction phase.
