Renovating your home is about reducing energy waste. Energy conservation work aims to reduce our energy costs and also protect our environment.
According to the IEA (International Energy Agency), real estate has the potential to reduce its CO2 emissions by 24% by 2050, just with renewable energies, knowing that old housing is the biggest consumer of energy. As a result, homes are poorly insulated and therefore consume more energy.
You live in an old home, its energy consumption and greenhouse gas emissions are considerable, so you are considering saving on energy costs and protecting your environment.
To do this, accessible means are at your disposal to carry out a quality renovation, knowing that improving your home will also allow you to enjoy better comfort.
Renovation works to save energy are: heating, insulation, air quality.
The heating system
It is important to control the ambient temperature of your home to achieve real savings in order to reduce your bill, knowing that heating and domestic hot water production (electric water heater) are the most important items in terms of energy consumption. It is therefore advisable to opt for ecological heating.
Rehabilitating the insulation from the outside reduces the need for heating and air conditioning. Reinforcing the insulation of your home also means making significant savings, because you will avoid heat loss in winter, but also having freshness in summer.
Therefore, you can choose natural insulators that have a thermal conductivity between 0.040W/m²C and 0.06W/m²C, such as vegetable, mineral or recycled insulators.
Improving air quality through a Canadian well that can be combined with high-performance ventilation systems such as dual flow CMV or heat pumps also has many advantages.
Energy saving work: the areas to be treated as a priority
To reduce your energy bill as much as possible, the areas to be treated as a priority in terms of insulation are:
- the roof: hot air accumulates in height if the latter is poorly insulated, there is a heat loss of 25 to 30%;
- poorly insulated walls correspond to a heat loss of 20 to 25%;
- openings such as windows and doors: about 10 to 15% of heat loss from a house,
- the floor: 7 to 10% of loss;
- thermal bridges, on the other hand, correspond to a loss of 5 to 10%.
Assistance for this work
When performing energy-saving work, you can benefit, under certain conditions and criteria, from various financial assistance to carry out insulation work on walls and roofs, or work on the heating system or domestic hot water equipment.
Some government schemes aim to facilitate the provision of eco-loans by banks to low-income households undertaking work to improve the energy performance of existing housing. The scheme on energy transition for green growth, allows banking institutions to benefit from a guarantee when granting loans.
These government aids aim to bring together all public and private stakeholders in energy renovation and renewable energies. Some companies provide advisors to carry out a free assessment of your energy consumption and will indicate the work best suited to your home and the existing assistance available to you. They can answer your technical, financial or legal questions, and also advise you on how to reduce your energy consumption.
