Energy renovation has been at the heart of a number of projects and issues for several years. Aiming to improve the energy performance of a home but also to fight against CO2 emissions, it is framed by families of work, devices and conditioned by financial aid. The launch of France Rénov ‘strengthens the aid system.
On January 12, 2022, Emmanuelle Wargon, Minister for Housing, inaugurated the new public service for the energy renovation of housing: France Renov ‘. With the aim oferadicate thermal strainers, the service aims to be a one-stop-shop for simplify information and access to aid relating to energy renovation. Private owners wishing to carry out work to improve energy performance of their accommodation will now be able to be supported by the service which already has 1,000 advisers across the country.
What is an energy renovation?
The energy renovation of buildings (private homes as well as business premises) brings together a set of works that should lead to better energy performance (or efficiency). In other words, such work makes it possible to better control its energy consumption, to lower its energy bill but also to reduce its CO2 emissions. And this last objective is sizeable since the building remains a highly polluting sector in greenhouse gases in France with transport, industry, agriculture or the tertiary sector. This set of activities is known to actively participate in global warming, a vast problem that requires every government in the world to review its way of life.
But, at the individual level, energy renovation improves the quality of life, in particular through better thermal insulation, more efficient heating equipment or more modern ventilation systems. Among the affected and priority dwellings, those which are considered as “energy sieves”, that is to say very poorly insulated dwellings leading to overconsumption of energy. Most often, these are buildings dating from the 1970s, a period in which a key work item such as thermal insulation was not yet taken into consideration.
What works are affected by energy renovation?
The energy renovation of buildings provides for a set of work per shift: insulation, heating, ventilation. These three positions form the winning triptych and to help you choose the right equipment and techniques, you are supported and advised by building professionals. As such, we hear a lot of talk of RGE craftsmen, translate Recognized as guarantor of the environment. This label guarantees the involvement of these building professionals in carrying out energy renovation work and the use of renewable energies.
Priority within the framework of an energy renovation, thethermal insulation enables energy performance to be combined with lower greenhouse gas emissions. Not to mention that poor insulation leads to a loss of energy and increases the energy bill every month. Among the areas to be isolated, the roof which, according to figures from the Ecological Transition Agency (ADEME), generates nearly 30% of heat loss, but also floors and walls. Materials, thickness, techniques, so many parameters are integrated by professionals to achieve high-performance thermal insulation.
Without good thermal insulation, there is no efficient heating point! This is why isolating is the first task to be carried out. Then the choice of heating equipment and type of energy are two key points in the context of an energy renovation. Programmable radiators, thermostatic valves, condensing boilers, fresh water radiators, all the equipment recommended in order to improve performance and comfort on a daily basis.
And the use of renewable energies takes on its full meaning with heating equipment since thesolar energy (photovoltaic solar panels, thermodynamic water heater …), the geothermal (geothermal heat pump), the biomass (wood pellet or pellet stoves) or theaerothermal (Air-Air heat pump or Air-Water heat pump) meet the main challenges of energy renovation.
One healthy and properly ventilated housing is also a guarantee of energy savings and comfort. Energy renovation therefore includes ventilation among the key positions. Nowadays, the controlled mechanical ventilation (CMV), single or double flow, is the recommended equipment in order to maintain quality air and sanitized housing. There is even the distributed mechanical ventilation (VMR), a technology which ensures the renewal of the air in each room independently, and the mechanical ventilation by insufflation (VMI), a system that renews the air by injecting outside air, filtered and heated beforehand.
Doors and windows also affected
Other families of work are recommended in the context of an energy renovation, in particular the replacement of the openings (doors and windows) in order to ensure both good thermal and sound insulation of the home.
What aid and eligibility conditions in 2022?
Several devices, aids and conditions exist and are likely to change from one year to the next within the framework of the finance law. We will review the main ones for 2022, this list being non-exhaustive.
The birth of France Renov ‘
Latest in the framework of the climate and resilience law, France Renov ‘has been an active public service since 1is January 2022. Founded by the Ministry of Ecological Transition, it helps individuals with modest incomes who want to carry out energy renovation work. Free, objective and personalized, the advice given allows support throughout the work. France Renov ‘is of course a website rich in dedicated information, advice spaces and reception points throughout France, a single number (0 808 800 700) to talk to advisers about the entire process or even a financial aid simulation tool.
MaPrimeRénov ‘, formerly the Ecological Transition Tax Credit (CITE), is a financial aid offered by France Rénov’ intended for the most modest households who live in poorly insulated housing (main residence) (thermal strainers). Support, preferential financing rate and large-scale work are provided for in this system, which will see its terms unchanged in 2022.
MaPrimeRénov ‘Sérénité (formerly Live Better Serenity by Anah)
This aid is offered by the National Housing Agency (Anah) to people with modest to very modest incomes in order to support them in renovating their main residence. This financial boost is calculated according to the amount of the work, but it cannot exceed 18,000 euros.
Energy saving boost
This premium brings together two dedicated aids: one for insulation, the other for heating. It allows individuals to carry out energy renovation work such as insulation of the roof, attics or low floors and the installation of heating equipment using renewable energies.
VAT reduced to 5.5%
Intervening in the context of energy renovation works, VAT at a reduced rate of 5.5% is applied on the condition of calling on a professional for both the work and the equipment.
