The house passivates still called “low-energy-house” attracts followers more and more, a situation which is explained by the fact why it has a low energy consumption. The passion which this kind of dwelling knows appeared about ten years ago. It is especially in terms of heating that this construction dissociates others.
Energy consumption
The passive house is a house which consumes very little energy and it is a question here of using passive techniques to make it possible to the inhabitants to save a maximum of energy. For that, it essential to study well the orientation of the house and the site of the openings. That is essential, because it will be especially the solar energy which will be requested.
In this case, one speaks about bioclimatism where it would be necessary to optimize the elements of capture of the rays of the sun. It is even advised to choose a bioclimatic veranda. It would be also judicious to adapt the parts in order to allow a better air circulation in all the building.
The other essential point for the energy saving is the fact of increasing the insulation of construction. For that, it would be necessary to multiply the openings on the part which is exposed to the sun and to make the opposite on the less exposed parts.
However, in order to make it possible to keep more heat in the building, it is advised to choose the windows with triple glazings. With regard to the elements of insulation, they will have to be approximately a 10 cm thickness. All that will make it possible to keep the heat brought by the sun which will be very useful to heat the habitat when the night fall. The heat released by the inhabitants will also make it possible to keep a stable temperature in the house.
The cost of construction deadened in time
It should be known that the construction of a passive house requires a very important investment that for the ordinary houses. This is due to the fact that the materials which will be used in the construction industry are expensive. It takes indeed a considerable time for the manufacturing of certain elements. It is in particular the case for those which are used to increase the insulation of the building.
Moreover, the request is not very important yet in the field therefore the materials are not produced yet in series. To be able to acquire some, it is thus necessary to spend a rather important amount of money.
Even if the price of acquisition of such a good is raised enough, the benefit which will result from this are not less important. Specificities of the house will thus make it possible to the owners to make a considerable economy in terms of energy.
Tax incentives
The passive houses have also much advantages at the tax level, a situation which is seen especially on the tax cuts. Generally, the manufacturing of such a building would make it possible to the owners to reduce their tax up to 830 euros. Moreover, that will be applicable during the ten next years after the delivery of the good.
As regards the houses which have a certification Zero-energy, they profit from a tax cut which can reach 1700 euros. In fact the buildings consume only 15 kWh/m2 which can have this certification. |
