Energy consumption

• Primary energy need : 40,00 kWhep/m².an

Calculation method : RT 2012

• Initial consumption : 475,00 kWhep/m².an

Envelope performance

More information :

As far as the envelope is concerned, the concrete walls have been insulated internally with 20 cm of cellulose wadding, the attic has been insulated with 40 cm of cellulose wadding and the lower floor with polyurethane foam. 6 cm. All of the windows have been replaced by PVC joinery in double glazing.

More information

We have not yet had time to carry out a control audit, nor to have a year of consumption to assess the actual consumption of the building. Similarly, we have not yet done the air tightness test which is planned in the coming weeks.

More information

This is a global renovation project aiming at a BBC renovation level. The initial thermal audit allowed us to define two work scenarios, one allowing a minimum reduction of 30% in energy consumption, the other allowing a reduction of about 400 kWh/m²/year. We opted for the more efficient scenario so that the house could significantly reduce its carbon impact. We also chose to switch to renewable energy for heating and domestic hot water, by installing a wood pellet boiler in place of the old original oil boiler.

Systems

Heating system :
• Water radiator
• Low temperature floor heating
• Wood boiler
Hot water system :
• Wood boiler
Cooling system :
• No cooling system
Ventilation system :
• Humidity sensitive Air Handling Unit (Hygro B
Renewable systems :
• Biomass boiler
• Renewable energy production : 60,00 %

We made the choice of the production of heat by wood in substitution of the old oil boiler. The boiler guarantees both the heating of the house as well as the production of domestic hot water.

This choice was dictated by several reasons:
- The regulations in force as well as our ecological commitment have prompted us to abandon the old oil-fired system;
- Wood is a renewable energy that significantly reduces greenhouse gas emissions;
- The price of wood energy was very competitive on the market and seemed able to guarantee us limited energy expenditure;
- The wood boiler can supply both the old emission system by radiators upstairs, which we wanted to keep in a process of reuse, while allowing us to install a heated floor on the ground floor.

The house is located on agricultural land between the villages of Pouilly-Le-Monial and Jarnioux, in the Commune of Porte des Pierres Dorées.

To the east, a wood (left abandoned) of 10,000m² runs along the width of the land.
To the north, an uncultivated meadow of 8,000m² borders the land.
To the south, passes the departmental road which connects the two villages.
To the west, there is a hamlet with around ten individual houses with private gardens.

Bus stop in front of the house.

Primary school at 800m.

Shops can be reached by car, except for a mini-market, a bakery and a hairdresser 600m away, in the center of Pouilly le Monial.

The only and leading manufacturer of recycled paint in France, CIRCOULEUR recycles and transforms unused paint! By avoiding the incineration of acrylic paints and the extraction of new raw materials, a high-performance ecological paint is produced, with an environmental impact 12 times lower than a conventional paint.
Circouleur also works with people in professional reintegration and with disabilities.
The whole house was painted with these unique paints in France!

The plasterer was surprised and reluctant at first. After seeing the result, he was happy to have discovered the innovation brought by Circouleur!

Permaculture

The results of the impact calculation do not include the reuse of the following furnishing materials:

• Wooden door frames
• Polyurethane cornices
• All the furniture in the house including: sofas, armchairs, tables, beds, cupboards, shelves, household appliances (oven, toaster, washing machine, hotplates, freezer, hood), furniture for the summer garden ...
• Decoration: crockery, vases, frames, mirrors, lighting (lamps, sconces, etc.), all garden tools (lawn mower, wheelbarrow, watering can, garden hose, shovel, rake, garden stone sink, etc.)
• Metal placo rails


Our objective is not limited to reusing materials from the second work, but also includes the desire not to have recourse to the raw material in the decorative aspect: we buy (or recover) second-hand articles, or in the case appliances, refurbished products.

Economic assessment

• Total cost of reuse : 8 000 €
• Cost of reuse in percentage of the operation : 5 %
• Saving realised thanks to the implementation of reused materials compared to new materials : 25 000 €

Social economy

Social economy and professional integration :

The paint used for the walls and ceilings, Circouleur, is an SSE structure because it works with people in professional reintegration to sort paints for recycling, and with people with disabilities, through an Esat, to labeling paint cans.

Comfort

Temperature level :

The 20cm thick insulation guarantees a high level of thermal comfort.

We were able to see this this summer during the heat waves: at the end of October/beginning of November, despite the outside temperatures which had dropped, we did not need to turn on the heating, the inside temperature remaining at 19°C.

GHG emissions

• GHG in use : 1,00 KgCO₂/m²/an
