The essential points to know for a successful energy renewal

Energy renewal is a crucial topic for owners and housing tenants, in particular as regards the improvement of the energy efficiency of the buildings.

Understanding its aspects allows to obtain substantial savings and contribute to the conservation of the environment. Below, we will explore various key elements of energy renewal, such as isolation, roof, orientation and position of the building.

What is the renewal of energy?

Energy renewal includes a series of works to improve the thermal and energy performance of a building. These interventions not only reduce energy consumption, but also to improve occupants' comfort.

This renewal may include different types of work, such as isolation, the replacement of heating systems or even the implementation of renewable energy production devices. For more information on these practices, you can consult this site: the Breton Center of L'Abitat.

The importance of isolation in the renewal of energy

The isolation plays a fundamental role in reducing the thermal loss of housing. Good isolation limits heat losses in winter and keeps freshness in the summer. There are several insulation techniques, adapted to the different parts of the house: walls, roofs, floors and windows.

The different types of insulation

There are several insulation methods. The isolation from the inside consists in placing insulating materials on the internal walls, while the isolation from the outside covers the facades of the building with insulating panels.

The latter solution is often more effective because it limits thermal bridges. The roof insulation is also crucial because most of the thermal losses are performed by the roof. Finally, the insulation of the attic, lost or developed, also contributes to substantial energy savings.

The role of the roof in energy efficiency

The roof is a key element in any process of renewal of energy. In fact, up to 30% of heat leaks can be loaded on a poorly isolated roof. The renewal of the roof generally includes the revision of its seal and the cooling of its thermal insulation.

Materials for good roof insulation

Two main types of materials are used to isolate the roof: thin isolation and often insulation. The former are less bulky and are perfectly suitable for limited spaces, however they must be installed as well as other insulating solutions because their only efficiency is limited.

Isolation often as rock wool or glass wool has better thermal performance. However, they require more space to install.

Advantages of a well isolated roof

A well -insulated roof allows you to reduce not only energy costs related to heating and air conditioning, but also guarantees better thermal comfort throughout the year.

In addition, an adequately isolated structure appreciates the property by increasing its energy class. This can be essential when they sell or rent accommodation.

Orientation and position of the building

The orientation of a building significantly influences its energy consumption. The well -oriented accommodation recovers the maximum free sun intake, thus limiting the needs in heating and artificial lighting.

Impact of orientation on energy performance

Ideally, the main rooms (living room, dining room) should be oriented to the south to benefit from the maximum sun. The rooms can be directed to the east, ensuring a pleasant temperature in the evening.

The service parts can be positioned in the north. In addition, to design progress on the roof or place deciduous trees near the windows, it allows you to naturally adjust the internal temperature based on the seasons.

Influence of the geographical position

The geographical position also affects the energy efficiency of a building. For example, a house located in a cold region requires reinforced insulation compared to a house located in a temperate area. The local climate must therefore be taken into consideration by the energy design or renewal phase.

Techniques and materials for the renewal of energy

Different techniques and materials can be used to optimize the energy performance of a building. Choosing the right insulating materials, replacing the old windows with more efficient models or integrating renewable energies, they are all possible solutions.

Efficient heating and cooling systems

Replace a dilapidated heating system with a condensing boiler, a heat pump or photovoltaic panels significantly improves energy efficiency. These modern equipment consume less energy and use renewable energy sources.

Positioning programmable thermostats and thermostatic valves on radiators also allows you to better adjust the temperature and obtain substantial savings.

Use of high -performance Windows

The windows also play a crucial role in the renewal of energy. Opt for double or triple windows for double windows limits heat losses.

PVC or wood frames offer good insulating performance and last long. For even more efficiency, it is recommended to add sun protection devices such as rollers or outdoor curtains.

Walls and floors

The isolation of walls and floors must not be overlooked. Complete energy renewal by reducing thermal bridges.

The materials used vary according to necessity: cellular cement, expanded or extruded polystyrene, cellulose muffler, among others. Make sure to choose efficient and respectful materials of the environment.

Economic and environmental issues

Energy by renewing a building represents a certain cost, but the available subsidies and financial aid allow you to make these works accessible to everyone. There are incentive devices such as energy prizes, tax credits or even zero loans -rate.

Long -term financial benefits

Although the initial costs may seem high, the return on investments is tangible thanks to the energy savings made month after month. Therefore, energy bills decrease considerably, allowing owners to carry out the work.

Positive impact on the environment

In addition to the economic benefits, energy renewal actively contributes to the protection of our planet. Reducing energy consumption reduces carbon imprint, thus participating in the fight against global warming.

Use ecological materials and use renewable energy sources strengthen this ecological commitment.
