Energy-intensive building

As part of the design and implementation of a passive ecological deposit, we have adopted a holistic approach to building. Our goal is to disseminate our knowledge and know-how in the field of passive biosourced building.

Sustainable development approach of the project owner

Bioclimatic house, biosourced materials, passive design, autonomy in water

Architectural description

This building totally blends into its environment.
Located in the Ile de France, it is part of the landscape in all discretion. The facades are covered with an insulating coating very "perspirant" and then painted in a stone tone similar to the concrete coatings of the neighbors. A roof with two slopes covered with tiles harmonizes with the neighborhood. The exceptional elements are to be discovered inside.

Building users opinion

House cool in summer and warm in winter. Very pleasant to live, no feeling of current of cold air. The lodge welcomes tourists from all five continents. The lodging has been unanimous since its opening.

More information

The calculation method used is PHPP. A regular follow-up allowed us to check that the house has been working perfectly for 5 years with 4 people. Since the opening of the lodging the consumptions have greatly increased. It is very difficult to educate visitors. This demonstrates how the use of a building affects its energy balance. It is imperative to have a responsible approach to energy to optimize the liability.

    This innovative system that considers water through the 4 elements, coupled with a biological filtration system and lagooning ensures the home passive ecological self-contained water.

    The AMILO diesel filtration system has been certified by:
    - NSF independent international certification body for human health products
    - Water Quality Information and testing laboratory products for industry and water professionals
    - USA Environment Prtotection Agency Organization for the Protection of Human Health and the Environment Laboratories & Research

  • 16 000,00
  • 45 000
  • 530 000

GHG emissions

  • 5,00 KgCO2/m2/an
  • In use, priority is given to solar thermal, which covers about 60% of the domestic hot water requirements and contributes 20% to heating, and then wood covers 30% of the winter calories of the ball

  • 60,00 KgCO2 /m2
  • 100,00 année(s)
  • Based on ADEME method. The envelope consists of monomur terracotta brick, exterior cellulose insulation, wooden floor and brick wall of raw earth.
