Mold growth on walls also indicates a thermal problem. It grows in cold corners of your home. These areas represent significant thermal bridges.
Excessive humidity stems from a temperature imbalance. Warm indoor air cools abruptly when it comes into contact with cold walls. This process generates condensation and promotes mold growth.
Insufficient ventilation exacerbates this problem in thermal sieves. Moisture remains trapped in the home without effective ventilation. This situation gradually deteriorates the building’s structure.
Abnormally high energy bills
Excessive energy bills are a reliable indicator. You’re experiencing above-average energy consumption. This situation is a direct result of poor thermal performance.
Compare your costs with those of similar properties. A significant difference indicates an insulation problem. Your heating system is constantly working to maintain the temperature.
Thermal colanders consume up to three times more energy. This excess consumption significantly increases your budget, representing hundreds of euros wasted each year.
A quote for energy renovation work then becomes relevant. The investment in insulation quickly pays for itself. You sustainably reduce your bills while improving your comfort.
The heating that works constantly
Your heating system runs almost continuously in winter. It struggles to maintain a comfortable temperature. This situation clearly indicates a thermal strainer.
The thermostat remains constantly active despite moderate settings. Heat escapes quickly through various weak points. Your home cools down as soon as the heating is turned off.
The rooms have very uneven temperatures. Some areas remain cold despite intense heating. This thermal imbalance reveals localized insulation problems.
Energy inefficiency also affects your overall comfort. You need to wear warm clothes even indoors. This unpleasant situation persists throughout the cold season.
The energy performance diagnosis (DPE)
The energy performance diagnosis is the official benchmark tool. It precisely assesses the thermal efficiency of your home. This mandatory document classifies your home according to its energy consumption level.
Understanding energy classification from A to G
The DPE classifies housing on a scale from A to G. Categories F and G officially identify thermal sieves. This classification is based on annual energy consumption.
Class A represents high-performance housing. They consume less than 70 kWh/m²/year. Thermal sieves generally exceed 330 kWh/m²/year.
The ranking also takes into account greenhouse gas emissions. This dual assessment provides a comprehensive view of performance and effectively guides your renovation priorities.
The 2021 DPE reform has strengthened its reliability. Calculations are now based on objective criteria. The thermal sieve’s status thus becomes undeniable.
How does a DPE take place?
A certified diagnostician performs this mandatory assessment. They carefully examine all the thermal elements of the home. Their inspection covers insulation, heating, and ventilation.
The professional records the precise characteristics of your home. He or she measures the surface area and analyzes the materials used. This data is fed into a specific calculation software.
The inspection also includes energy systems. The diagnostician evaluates your heating and hot water production. He also examines ventilation and air conditioning systems.
This assessment typically lasts between one and two hours. The professional takes photos and notes their observations. They then prepare a comprehensive report, including the energy rating.
Interpreting the results of the DPE
The DPE report presents your estimated energy consumption. It precisely indicates your energy class from A to G. The F and G ratings confirm your thermal sieve status.
The document also details the weak points of the home. It identifies the main sources of heat loss. This information will effectively guide your future renovation work.
The report also provides recommendations for improvement. It suggests priority work to improve performance. Each suggestion is accompanied by an energy savings estimate.
Reno ‘s expertise helps you interpret these results. Our specialists analyze your DPE in detail. We then develop a personalized and effective renovation plan.
Validity and cost of an energy diagnosis
The DPE remains valid for ten years since 2021. This period gives you time to organize your work. The document remains mandatory for all real estate transactions.
The cost of the diagnostic varies between 100 and 250 euros. This price depends primarily on the size of the home. Higher rates apply for larger homes.
Some local authorities offer grants to finance this assessment. These subsidies significantly reduce your investment. Check with your town hall or department for details.
Investing in an energy performance certificate (EPC) is always worthwhile. It provides you with detailed knowledge of your home’s performance. This information effectively guides your energy renovation decisions.
Critical points to inspect yourself
Before calling a professional, you can perform an initial diagnostic. Certain elements easily reveal thermal weaknesses. Your careful observation already provides valuable insights.
Insulation of walls and attics
Exterior walls are often the main weak point. They represent the largest surface area in contact with the exterior. Their poor insulation generates significant heat loss.
Touch the walls in cold weather to assess their insulation. A cold feeling clearly indicates a thermal problem. This simple method effectively reveals critical areas.
Poorly insulated attics cause up to 30% of heat loss. Heat rises naturally and escapes through the roof. A visual inspection of the attic allows you to assess the existing insulation.
Wall and attic renovations are becoming a priority. They significantly improve energy performance. The investment quickly pays for itself thanks to the savings .
Joinery and glazing
Old windows create significant thermal leaks. Single glazing has very low thermal resistance. It creates a feeling of cold even without a draft.
Inspect the seals around windows and doors. Cracks or loose seals allow air to leak in. These defects significantly deteriorate the overall insulation.
The candle test effectively reveals drafts. Hold a flame close to closed openings. Its movement clearly indicates cold air infiltration.
Installing double or triple glazing transforms thermal comfort. It significantly reduces heat loss. This improvement also reduces external noise pollution.
The heating system and its performance
An outdated heating system compromises energy efficiency. Older appliances consume more energy for mediocre results. Their efficiency gradually declines over the years.
Check the age and condition of your heating system. Appliances over fifteen years old often have insufficient efficiency. Replacing them then becomes economically viable.
Also observe the heat distribution in your home. Persistent cold spots indicate an imbalance in the system. This situation requires a complete overhaul of the installation.
New technologies such as heat pumps offer efficient alternatives. They significantly reduce your energy consumption. These modern solutions are ideal for renovating thermal sieves.
Housing ventilation
Inadequate ventilation exacerbates thermal problems. It causes significant heat loss. It also promotes the accumulation of humidity in the home.
Inspect your air vents and intakes. Make sure they’re not blocked or clogged. Their proper functioning remains essential for thermal balance.
Excessive condensation on windows indicates insufficient ventilation. Moisture builds up, creating an uncomfortable environment. It also promotes the growth of harmful mold.
Installing a dual-flow CMV significantly improves energy efficiency. It recovers heat from the extracted air to preheat the incoming air. This system significantly reduces heating requirements.
