Energy-intensive building

Two months after receiving the E+C-label by the Minister of Housing and having reached the Energy 3 and Carbon 1 levels, Ecolocost decided to have this house certified with the new BEPOS Effinergie 2017 label to demonstrate its qualities.

The purpose of this house is to demonstrate the feasibility of a revolutionary house with traditional looks, all in a record time for 200 € more expensive per square meter than a house solely following the French RT2012 regulation.

Important points are:

  • Its compactness in order to use the least possible floor area and remain desirable. A functional 3-bedroom house of 82m2 that respects the fundamentals of a quality habitat in all points of view (air, noise, comfort)

  • Its affordable cost: the house was designed to cost 1/3 of the average monthly income of a family of first-time homeowners in highly urbanized areas, about 1,000 € per month land included. Without any energy expenditure since its low electricity consumption is totally covered by its production to reach the annual equilibrium.

  • Its carbon impact, thanks to wood and high quality materials that are fully recyclable, as well as high-quality technical equipment. This house is truly sustainable, can be assembled in a single day and generates virtually no construction waste and no nuisance for the residents.

The goal is to be able to massify the production of affordable positive energy homes by adapting to all architectural types and considerably reducing the construction time.

Owner approach of sustainability

The objective of this project was to make a low-cost 3-bedroom house of very high quality that could be BEPOS Effinergie 2017certified in the financial sense of the term (-0 € over the year) by not using fossil energy sources for its use.

Architectural description

We favored a cubic architecture with 2 solid facades to be able to copy this model in band. This timber frame house has a classic appearance where it is impossible to distinguish the difference with a masonry house.

If you had to do it again?

We have concerns about the installation of the CMV which was a bit laborious, we will do the same on the same ground by addressing this problem upstream.

Building users opinion

The house will be inhabited starting June 1st, 2017, it is planned to study its real life cycle from this date

  • The Compact P system is a modular system offering not one, but several solutions. The Compact P is a ventilation and heating system that provides home ventilation, heat recovery and domestic hot water production. This ensures a daily renewal of the air by evacuating dust, odors and excess moisture for a healthy and pleasant indoor atmosphere. When it is warmer inside and outside the house, an integrated by-pass allows fresh air to penetrate directly to cool to the maximum without using extra energy.

    The Compact P system is a modular system offering not one, but several solutions. This allows you to choose the solution best suited to the size of your home and the needs of your family. The first element of a Compact P solution is always the Compact P itself, the true heart of the system. The Compact P is a supplemental ventilation and heating system ensuring your home ventilation, heat recovery and domestic hot water production. This ensures a daily renewal of the air by evacuating dust, odors and excess moisture for a healthy and pleasant indoor atmosphere. When it is warmer inside and outside the house, an integrated by-pass allows fresh air to penetrate directly to cool to the maximum without using extra energy. If you are looking for a central heating solution, we recommend a Compact P solution with an aerothermal or geothermal heat pump. Only three systems of ventilation and heating in the world benefit from the famous certification passive house, and the Compact P of Nilan is one of them. This certification means that the Compact P is approved for the passive habitat without having to provide additional documentation.

    This machine is ideal in terms of simplicity for a 4 in 1 system (ventilation, heating, DHW and refreshment)
