Energy-intensive building

After several years of R & D, Avenidor has embarked on an extraordinary project: to build the 1st Passive Premium certified and 100% autonomous house in the world.

The Avenidor building is located in the KZB Group's sustainable housing center (Ahun in Creuse).

Here are the peculiarities of this house:

  • Certified passive premium by the PassivHaus Institute

No heating or cooling system (thanks to the design of the envelope and the orientation of the building in order to make the most of the solar contributions)

  • Exceptional living comfort (no cold areas, optimal air quality, etc.)

100% autonomous in electricity (fields of photovoltaic panels bi-facial and park batteries)

100% autonomous in drinking water (rainwater drilling or recovery, filter body purification system and UV bactericide)

  • WIFI system without being connected to the traditional wired network (amplification of the 4g and redistribution in WIFI)

In short, this house is so powerful that it surpasses the RT2020 (future thermal regulation of the building), it works by making the most of what nature has to offer.

Our goal is to make this type of housing accessible to all and thus drastically reduce pollution related to buildings. That is why, from September 2018 we offer our solutions to individuals wishing to afford an exceptional house, tailor-made and eco-responsible.

Owner approach of sustainability

Pollution related to the building activity sector accounts for 25% of total CO2 emissions in France.

Alarmed by this observation Avenidor aims to design houses that have no impact on the environment, from their realization to their use. In order to take up this major challenge, the prototype presented here has been developed to consume very few resources and use only renewable energies, while favoring materials with low environmental impact.

Architectural description

Architecturally inspired Alsatian, the house Avenidor is built of cellular concrete (masonry material the least impacting ecologically and offering the best performance) and is insulated with polystyrene (recycled) extruded under raft and expanded in elevation. This house of 252m ², has 3 levels:

  • A basement in heated envelope
  • Ground floor (living room and open kitchen, WC)
  • R + 1 (3 bedroom and 3 bathroom)

Through its aesthetics, Avenidor demonstrates that a high-performance building can have a traditional architecture. One of the challenges of this construction was to make half-timbering reconstituted stone fixed directly on the ITE without diminishing the effectiveness. In addition to benefit from a perfect insulation (R of 10 on average overall envelope) the building is oriented in order to make the most of the bioclimatic contribution (maximum opening to the south and very little to the north) .Here is precisely the constructive mode of the house:

Raders:

From bottom to top :

  • All coming 100mm
  • Geotextile membrane
  • DOW XPS (λ = 0.029 W / mK) 240mm
  • Anti-hiking membrane
  • Reinforced concrete slab (λ = 2,500 W / mK) 300mm

U Radices = 0.104W / (m²K)

Exterior walls:

From outside to inside walls:

  • 25 mm reconstituted stone cladding (aesthetic function)
  • Crepe facade covering 15 mm
  • TE ZOLPAN EPS (λ = 0.038 W / mK) 200mm
  • YTONG cellular concrete block (λ = 0.090 W / mK) 365mm
  • SIGA steam
  • Unvented air gap 48mm
  • 18mm plasterboard

    UMurs ext = 0.098W / (m²K)

Roofing:

From outside to inside:

  • Roof tiles
  • By rain
  • Fir farmhouse
  • Projected cellulose wadding (λ = 0.039 W / mK) 600mm
  • Oriented Strand Board 22mm
  • SIGA steam
  • Ceiling in plasterboard 13mm

UToiture = 0.073W / (m² / K)

Window

  • HF310 Wood-aluminum frame chassis
  • Triple glazing 48mm, 44b.2 (VSG) / 16Ar / 4 / 15Ar / b4

U g-value = 0.88 W / (m²K)

g -value = 60%

Uw = 0.898 W / (m²K)

If you had to do it again?

As our prototype house has achieved the expected consumption and performance targets, we would like to increase the share of bio-sourced in our homes. This is why we are currently developing a straw house carrier that will have the same performance and will also be 100% autonomous.

All the people having stayed in our house are unanimous on the comfort of life which it proposes:
Irreproachable quality of the air managed by the VMC double flux.
Outstanding acoustic comfort
Feeling of homogeneous heat throughout the house

    Management / Coinvolgimento dei stakeholders

    1st certified Passive Premium home and 100% autonomous. It is the combination of materials, equipment, know-how and studies that made this house a success. Nowadays we have the experience and the technology to build the future, why stay anchored in the past?

    Each stakeholder must be told the purpose and the issue of their work. On-site crews are rigorous when they understand the impact of their tasks on building performance. The most complicated is to obtain the insurance of CMiste (procedure started in November 2017 ...)
