Energy-intensive building

The house Europassive® 2 Ho result of a bioclimatic design integrating the constraints of a plot and regulation of new development. The general concept was to give an overall unit to two different organizational entities: the volume heated and unheated volume. Technically structural envelope to the passive volume is continuous (including tile) to prevent any thermal bridge. It is laid on concrete sleepers. The insulation consists of cellulose wadding and blown panels of wood fibers.

  • In the end, its performances are exceptional: a heating requirement of 8 kWh / m2 year
  • A total primary energy consumption of 92kWh / m2 / year

Sustainable development approach of the project owner

Attached is the testimony of the Masters Authority:

"Our prime contractor has been able to move towards solutions related to solar energy, recycled and bio-based materials, and a reduced carbon footprint. He recommended solar energy for heating and domestic hot water , insulation made from recycled materials (tissue paper). During construction, recycling of waste and scrap materials was favored, most of the artisans was chosen in a perimeter of 25 km, from the perspective of a "clean" construction and low in CO2. These actions are perfectly consistent with the approach of the construction by KMO agency, which is based on wood construction and the most modern eco-labels ".

Architectural description

Bioclimatic design, bio-based materials, very healthy indoor air.

Building users opinion

Testimonies of Mr. & Mrs. POINSOT:

We were very happy to work with the agency KMO:

• Very available to give shape to the project from the design, reflect together, suggest solutions, and advise us,
• A follow very regular and extremely reassuring site: the Work of Master has been present every day on site at key moments. The site meeting was routine each week, with mandatory presence of the speakers,
• A requirement of the Master Work of inflexible vis-à-vis the companies working on the construction, which has borne fruit so that nothing is left to chance, and that all the details are known and controlled,
• An impeccable compliance deadlines, if not record,
• A result that meets our demand, in addition to being well within the requirements of the Passivhaus label.

If you had to do it again?

The project owners have reported me to have my full confidence and would even be ready to begin the adventure to further improve the concept.
