Why start an energy renovation today?
Excessive energy consumption
Many Belgian homes built before the 2000s are poorly or inadequately insulated. As a result, heat loss is significant, especially through the roof, walls, and windows. This translates into high heating bills, thermal discomfort in winter and summer, and a heavier ecological footprint.
Thermal and acoustic discomfort
Poor insulation or an outdated heating system can create cold sensations near walls, icy floors, or temperature variations from one room to another. This lack of comfort can also be accompanied by noise disturbances, especially in adjoining homes or apartments.
A property less attractive on the real estate market
Today, a building's energy performance plays a crucial role in its attractiveness. A poor energy performance certificate score can lead to a significant depreciation at resale or rental. Conversely, a renovated and well-rated property is a major asset in the current context.
Works to consider to improve the performance of your home
To improve the performance of your home, start with an energy audit. Then, insulate the envelope, modernize heating and ventilation, and integrate renewable energies. Each step optimizes comfort, efficiency, and savings.
What long-term benefits for your comfort and budget?
Enjoy complete administrative support, a tailored site (in one or several phases), and a team of all trades. Avenir Rénovations optimizes your comfort while controlling your budget through effective coordination and financial assistance.
Regional grants can cover a significant part of the work. However, you must gather the right documents, follow the steps, and hire certified contractors. We assist you in compiling the file, monitoring the audit, and the procedures with the administration.
Some energy renovations can be done all at once, while others must be phased according to the budget. Avenir Rénovations offers you a progressive renovation plan, avoiding redundancies or technical conflicts between trades (e.g.: avoiding having to break an insulated wall to rerun a pipe).
Insulation, heating, ventilation, carpentry: our network of professionals covers all necessary skills, with a unique project manager to ensure overall coherence.

FAQ: Energy renovation in Belgium
Is the energy audit mandatory?
In Walloon Region and Brussels, an audit is required to access the main regional aids. It must be carried out by a certified auditor. This audit allows you to obtain a roadmap and justify the work undertaken. Avenir Rénovations connects you with a certified partner.
What are the most cost-effective works?
Roof insulation is generally the first area to target, as the losses are the most significant there. Next come the walls, the frames, and finally the technical systems (heating, ventilation). Each project is unique, but these steps are most often recommended by auditors.
How long do the works last?
It depends on the scope. Roof insulation takes 1 to 2 weeks, a comprehensive energy renovation several months if phased. We provide you with a detailed schedule before the start of the work and ensure regular follow-up.
