To build green, good decisions to be applied
It is not very to have the good construction project, it is also necessary to know well to prepare its project for an optimal optimization. Green construction must in this direction being privileged to the maximum, in particular by the use of éco materials, but also by a total review in the manner of building.
The choice of the good adapted material
To build ecologist consists to follow and respect in a strict way the principles of sustainable development. Once applied that led to a respect and a control of the environment.
Mainly, the use of éco materials instead of traditional materials of construction proves one of the first steps that the éco manufacturers cross initially. Their technical capabilities and functional calculuses similar to the matters more usually used in terms of safety, architectural quality, longevity and fire resistance launched a tendency to the green real estate.
In the same way, the production and the recycling of such materials make it possible to decrease the calorific impact on the environment of the phase of production to that of routing towards the building site.
Their use as diversified as the source of which they can come made ecological choice from construction a commitment for the long run while respecting the principle of sustainable development.
The principal criterion retained by adopting this kind of means is the weakness of cost in terms of gray energy. Gray energy it is the primary energy used during making of a material. The éco materials drawing their source from nature are weak of cost on this level.
The examples of éco materials which currently have the coast and being able to be produced at the local level: wood, ground, the wool of sheep.
To reconsider its construction for a better adaptation to the éco system around
The use of materials with environmental low costs is not all it is also necessary to take account of the parameters of construction of the house.
A plan optimized for a Southern installation full will be able to see a significant reduction in energy consumption for lighting. The natural light easily being able to serve as lighting for this reason. The choice of the ground is thus important, because in the event of bad situation compared to the sun, the invoice of energy can be found penalized of 20% of more than one correctly directed house. Measurement will relate to especially the parts of life such as the rooms, where an optimal orientation will allow the warming and the lighting of the part without preoccupation with an additional expenditure of energy.
The double glazings are advised for the southern windows and with triple glazing concerning the openings towards North. In the same way, it is preferable to forget the use of the round windows whose concrete frame remains a cold bridge letting heat escape.
The main source of energy expense in a traditional house is located in the expenditure to compensate for the thermal losses. So to optimize its thermal isolation proves to be necessary to limit the costs. Within the framework of a éco construction, nature offers many alternatives to the traditional elements of insulation. They can be animal substances such as the wool of sheep or of vegetable matters such as the flax or particularly interesting hemp within the framework of a éco construction.
In addition to already quoted measurements, a responsible attitude can also pass by a system of saving rainwater recovery and in water, a better management of the sorting and recovery of waste, but also by the taking into account of the consequences of construction on the environment which surrounds it.
Added to all this, true a éco construction will use to the maximum the capacities offered by alternative energies such as geothermics or solar energy.
Are you owner of your house?
Make profitable your roof and reduce your invoices up to 70% each month!
Grace to thermal panels, you can convert solar energy and heat your house. You contribute thus to the reduction of the CO2 emissions and the safeguarding of planet, by using an inexhaustible energy source. That will not only enable you to reduce your invoices by producing to you even your energy but to as be less depend on the fluctuations of price of energy as you buy. Moreover, you can profit from a tax credit and State aid to help you to finance your installation.
