The passive house concept is based on the building traditions of the pastInitiated in the seventies in Germany, they have since become a popular concept deal with current environmental issues. This type of housing responds in part to ecological principles to preserve the environment.
How to turn his house into passive house?
The transformation of a house to house passive response to a simple requirement: the reduction of at least 80% of energy consumption or at least to give the character of energy self-sufficiency in heating.
The challenge is therefore situated in achieving this goal of energy conservation. This requires in particular the reduction of heat loss but also by increasing the efficiency of renewable energy.
To achieve this type of renovation, four basic points should be considered:
· The thermal insulation: it must be installed and thought in order to reduce the presence of thermal bridges. For maximum efficiency, insulation will be installed on the outside of the building.
· The breakdown: it is important or even essential in a home to focus on passive ventilation of the building. And install double-flow ventilation can ultimately prevent heat loss through openings such as doors and windows. VMC provides a conventional exhaust stale air and the renewal of clean air.
· The openings: the main sources of heat loss, the openings (windows, skylights ...) must be completely isolated with methods such as double or triple glazingIn addition, they must be properly oriented to take advantage of solar radiation.
· The air tightness of the construction
Advantages of a passive house.
The passive house is a solution for reducing energy consumption among manyIt represents an effective solution as regards heating and the distribution of the energy.
It provides, due to the decrease in energy consumption, a certain independence from fossil fuels. The traditional energy sources are generally oil and its derivatives.
The passive house can also get a better management of hot air while balancing the internal temperatures. The air circulation in a closed circuit also prevents the growth of mold or moisture. The modification of glass guarantees in addition to the reduction of heat loss, a significant sound insulation. These windows can also participate with the proper installation of energy storage.
It is true that the implementation of such works at first seems important. However, the added value and the energy efficiency provided by the facilities will be reflected in part on the property value but also on the energy bill.
The state also gives houses of this type of special aids such as tax credits or loans to do the work. The only significant green renovation is to pay attention to the specific techniques of this type of installation. All miscalculations or implementation may undermine the objectives of a passive house. |
