Everything about interior design and energy performance

The subject of energy performance is currently at the heart of government policies, as well as the center of attention of households that see their purchasing power are reduced as the gas rate increases.

In five months, the regulated gas rate increased five times in a row, 4.4%, 9.96%, 5.3%, 8.7%, and 12.6%respectively, before the State set up measures to control these increases, including the gender of prices.

Heating represents 67% of household energy consumption, it is therefore naturally the first position on which we can intervene effectively. In addition, the lifespan of a boiler up to 25 years, many equipment still in operation today is obsolete and consume much more than the more recently designed models, with the current energy consciousness.

Premiums are granted to households which replace this equipment, in particular boilers that operate on domestic fuel or propane. Depending on the price of the new boiler and household revenues, the new equipment can be fully funded by subsidies.

The accommodation whose heating works mainly on city gas are particularly concerned, following the price increases previously mentioned. A news
boiler allows on averageSave 15 to 20% of its consumptionor even 30% when the installed boiler is over 15 years old. For a house with an annual consumption of 15,000 kWh, the price per kWh of gas at the regulated rate currently being 0.088 € (in the price zone 2 for the price B1), this represents a saving of € 396 per year.

The wood heating is particularly highlighted today, users particularly appreciate the wood stoves or at granulesas well as insertsespecially for the large area that they can cover and the homogeneous and pleasant diffusion of heat. Unused wood chimneys are also often rehabilitated in order to comply with new standards and be able to reduce the use of heating operating on gas or electricity.

It is important to determine from the start if you want Change the heating installationas this can considerably affect the development of the interior of the accommodation. THE pellet stovesfor example, require a secure space in the center of the living space, which must therefore be thought of to integrate perfectly into the desired atmosphere and style of decoration.

In addition, the distribution of spaces can be optimized according to the heat distribution. Indeed, the recommended temperatures are lower in night rooms than in day spaces. It is recommended to have a temperature of 19 ° C in living rooms, 17 ° C in night spaces and 20 ° C in hygiene areas.

Finally, the renovation of the walls is an ideal opportunity to carry out insulation work upstream, since the whole aesthetic part will already be taken into account in the
decoration project. Subsidies can take charge of part of the work, in particular concerning insulation and ventilation. It is estimated that around 15% of the energy consumption of a housing can be saved by efficiently insulating the walls, mainly those overlooking the outside or a garage.

During the development of the work project, we can integrate the energy subject into the selection of various aesthetic elements.

An essential aspect of the work project is of course the selection of materials. The different textures will rather bring an atmosphere or another, while certain materials are adapted for certain uses rather than others. Decor zo soul offers coating advice, given the significant impact that this has on final comfort in the accommodation.

However, it is possible to integrate the question of energy performance in the selection of materialsin addition to the decorative aspect. For example, while stone or wood keep heat, granite or marble keep freshness. The selection of materials for the project can therefore have a significant impact on the
Housing comfort as well as on future energy bills.

Safety is also important, in the case of the installation of a wood or pellet stove, an insert or a wood chimney, the materials used for flooring there must be adapted and non -flammable, in the event of an accident or projection of sparks or embers.

The doors and windows are the opening points between the interior and the exterior. Formerly, they were designed to isolate the interior of the wind, rain and external elements. Aluminum or wooden window doors were therefore sufficient, generally with simple glazing. However, they generate strong loss of energy. It is estimated between 10 and 15% the loss of energy due to openings on the outside.

Now, theWindow insulation And doors is a key point of their design. The majority of glass walls are in double glazingeven triple glazing for those of superior quality. The energy efficiency of the accommodation, that is to say the amount of energy necessary to have the same comfort in the house, is then higher.

When selecting the doors and windows for the work project, the fact of integrating the dimension ofThermal insulation In the selection can thus save up to € 198 per year for the same house as the previous simulation.

Part of the replacement cost of the glass walls and openings on the outside is covered by the aid previously mentioned. In addition, this type of work often comes into the work funded by energy suppliers in the context of energy saving certificates. Indeed, energy suppliers are led to finance energy savings work in individuals and businesses to compensate for C02 emissions generated by their activity.

The glass pieces, such as verandas, input airlocks or porches, are parts that can particularly be optimized. Their orientation in relation to the sun as well as their provision in the accommodation are elements which must be taken into account. The selection of materials making up the glass walls and the roof must be meticulous so that the room in question retains its comfort both in rainy and ancestor.

Once the project is validated, work can start. It is then essential to regularly check the adequacy between the plans and the work carried out, as well as the conformity of the latter. Although the craftsmen are completely competent, an error can happen and it is amply preferable to realize it when the workers are on site only once the work is completed.

Having carried out the plans and designed the project since its creation, we are naturally indicated to support you in your renovation. But we are also able to advise you on projects carried out by others.

Our advisory role is to ensure that the plans are good understanding by workers, check the reception of materials and their quality, and manage incidents or unexpected that could occur by offering relevant and effective solutions.

Because renovation work can represent a large budget, it is natural to wish to benefit as much as possible from Aids and subsidies
Available to promote the improvement of the energy performance of the private housing stock.

For this, public advisers provide their advice for free and answer users’ issues, concerning the eligibility of work to public aids and subsidies. The latter can be granted by the State, local communities, energy suppliers as seen previously, according to income from the tax household or not, and depending on many criteria. France Rénov ‘advisers will be able to carry out all the simulations necessary to optimize the work budget and target those that will impact the energy consumption of housing.

Note that bonuses are granted to work projects which concern several categories of work, or which have a very strong impact on consumption, such as the bonus «exit of colander» which supports the projects allowing to get out of an energy label F or G, or the «low -consumption housing» bonus which supports the projects allowing to obtain an energy label A or B. These bonuses can go up to 1,500 € each and are cumulable with other aids and Subsidies.
