Energy: Renovating old buildings without increasing the bill
Hello, this is Claude. Renovating an old building without breaking the bank is possible thanks to a clever combination of government subsidies, eco-friendly materials, and energy-efficiency tips. The challenge: reducing energy consumption while respecting the unique character of the house.
- Apply for the energy efficiency bonus (CEE) before signing the quote.
- Create your account on MaPrimeRénov to prepare your application.
- Schedule an energy audit for an accurate diagnosis.
- Consult a RGE-certified craftsman specializing in thermal renovation.
- Use the interactive Rénov’Action map to discover regional aid.
To find out everything about grants for renovating old houses, this complete guide is a goldmine of information. And to delve deeper into the unsurprising energy-related aspects of the work, here’s a useful article on recent changes in energy renovation.
Energy renovation in old buildings: a challenge to be met without fearing the bill
Renovating a house built before 1990 often means improving thermal insulation and installing an eco-friendly heating system. This may seem out of reach, but current renovation grants make the project easier. The secret? Clearly coordinate MaPrimeRénov, the eco-PTZ and energy bonusesto reduce the remaining cost.
Insulating an attic or replacing a boiler are major steps to reduce heat loss. For very low-income households, subsidies can cover up to 90% of insulation work. A FAIRE advisor reminds us that “optimizing energy efficiency is not an expense, it’s a long-term investment.”
Did you know that?
In Brittany, Ms. C. renovated her 110 m² farmhouse with wood wool insulation and a pellet stove. Thanks to subsidies, she saved €800 per year, without altering the charm of the exposed beams.
Keys to effectively reducing energy renovation costs
Starting with an energy audit is the best way to avoid mistakes. This assessment highlights thermal weaknesses and proposes a suitable action plan.
| Work | MaPrimeRénov amount (€/m² or fixed amount) | Target audience |
|---|---|---|
| Roof insulation | €25 for very low incomes, €20 for low incomes | Owner-occupiers |
| Air/water heat pump | €5,000 for very modest incomes, €2,000 for the highest | Landlords and occupants |
| Energy audit | €500, decreasing according to income | Any home |
If it’s a stone house, opt for breathable insulation such as bio-based insulating brick. If it’s a timber frame structure, wood wool remains the gold standard. In all cases, it’s essential to combine insulation and ventilation to prevent dampness and pests, as explained in my dedicated article on… good energy audit practices.
Simple 3-step procedure
- Submit the energy bonus application before any quote is signed.
- Launch the MaPrimeRénov application with an audit for major works.
- Take out an eco-PTZ loan to spread out the remaining costs without interest.
Energy bonuses and eco-PTZ loans: a winning combination to better finance your renovations
There Energy bonus (CEE) The key to financing insulation or a new boiler remains the same. Remember, the application must be submitted before signing. The eco-PTZ, on the other hand, offers a zero-interest loan of up to €50,000 to spread out the payments.
For example, Mr. and Mrs. S. in Limoges insulated 100 m² of attic space thanks to energy grants and MaPrimeRénov, reducing their out-of-pocket expenses to €700. This made the project profitable in just two winters.
Some tips for combining aid effectively and reducing costs
- Remember to check your eligibility for each benefit based on your income.
- Pay particular attention to the quotes to ensure that the work is RGE certified.
- Find out about local aid that maximizes the national subsidy.
- Plan the work sequentially, following the order of the subsidies.
- Hire a Renov’ consultant for a flawless installation.
Eco-friendly materials and gentle renovation: how to reconcile old-world charm and energy efficiency
Respecting existing buildings is crucial. Traditional materials like lime-hemp or bio-based insulating bricks promote a balance between thermal insulation and breathability of the walls. This prevents moisture problems and preserves the natural appearance.
Reducing energy waste also involves sustainable solutions. Once again, choosing a well-certified RGE-certified professional will be an asset in proposing a suitable mix that won’t increase your bill.
A little tidbit: an old building near Toulouse saw its gas bill drop by 60% thanks to these wise choices and a modern double-flow ventilation system.
What type of assistance should be prioritized for an energy renovation of an old house?
Is an energy audit required for all work?
Only comprehensive works or MaPrimeRénov ‘Performance’ files require it, not for a single insulation measure.
How to avoid losing energy bonuses?
The application for the CEE bonus must be submitted before any quote is signed.
Does VAT reduce the bill?
Yes, at 5.5% on supplies installed by RGE certified professionals.
Can I receive multiple forms of assistance simultaneously?
Yes, as long as the correct order is respected: CEE, then MaPrimeRénov, then eco-PTZ.
Thank you for your interest; Claude
