Owner approach of sustainability

Nacarat is a developer fully committed to sustainable development. To do this, an ecodesign approach is systematically applied in all programs since 2011.

This project is a test project of the market's ability to foster modular timber construction, with high environmental performances, within a environement that usually is terribly conventional (detached houses subdivisions). This is also the first effective collaboration between Smart Module Concept, a subsidiary of Rabot Dutilleul who builds wooden buildings in a factory 4.0 and Nacarat, the developer pf the Rabot Dutilleul group. The project presented is the show house built in a few days. Another 21 houses of 80m² are still to be built yet.

Architectural description

With their wooden siding, the Seres Villas offer a contemporary architecture in perfect harmony with the green landscape with trees of the neighborhood. Covering an 80m² area, they generously open to the outside thanks to beautiful bay windows and all have a nice garden to relax with family.

If you had to do it again?

Smart Module Concept became subsidiary of Rabot Dutilleul, like Nacarat. The objective is indeed to deploy as much as possible to this industrial tool

    Studies were carried out for a group of 4 houses during design stage. To date, only the show house has been delivered. The results presented are the worst values.

Envelope performance

  • 0,12 W.m-2.K-1
  • Structure
    Three dimensional timber construction system: 2 bunk modules of 5 m wide and 10.5 m long
    Factory Integration of thermal insulation in timber frame
    - significant reduction in thermal bridge, allowing living space gains.
    - Sound insulation: the housing structures are completely independent (no common party wall and floor).

    Facades coverings
    - Made of poplar treated by cross-linking, an ecological process that can make the wood exceptionally stable, durable and resistant. Wood protective treatments that meet the standards. Natural resistance and maintenance-free wood. Flat sheets of fiber cement.

Life Cycle Analysis

    Smart module concept offers space modules wood frame, three-dimensional, almost all of the construction is done in the factory, flooring, tiles, kitchen, bathroom, networks, valves, etc. Of the 18 professions that intervene during the construction of a house only 3 worked on the construction site. The timber used in the building is "Lamibois" and "I-shaped beams" in solid wood core particle. In walls, butted solid wood .

    2in1 system:
    Controlled ventilation + water heater. Hot extracted air enters the 2in1 system, drawn in by the fan of the controlled ventilation. The heat pump collects the calories contained in the extracted air and heats the water in hot water cylinder. The cooled stale air is then discharged to the outside. The house is ventilated, the water is heated!
