Under the conditions of the threatening ecological situation on our planet humanity comes to the inevitable need to undertake measures to reduce or eliminate the negative impact of human activities on the environment. In this context the construction of green or green homes can be considered as a means to reduce the harmful effects of human presence. By changing his habits or his investment choices during the construction of his home, everyone can make the home healthier and significantly reduce energy consumption and natural resources. By acting together, we can come to contribute to the health of our planet.

Today we see the increasing number of green homes. They are growing but they are more than a fad. The green habitat fate of confidentiality and is becoming an important market segment of construction and renovation.

What houses can be called green? We can define the ecological efficiency as the ability of a device or a home to be environmentally controlled for a financial cost. A home is called "green" or "green" when built with natural and healthy materials, and its not working night or very little to the environment. One can also consider here the autonomous houses seeking energy independence and autonomous water management.

So the issues are primarily related to the additional expenses required to consrtuction such houses.

An estimated 7 000 - 9 000 green homes built each year in France. It is generally said that to build a green house generates an additional cost of 3 to 8%, mainly due to the addition of manpower and material costs, or home automation. This does not preclude projects multiply. We will try to analyze the examples of green building throughout the world in order to know the varieties and understand the scale of this process.

1. Save energy. It can reduce energy consumption by 90% when using all the knowledge available today. This is what motivated the development of whole neighborhoods, as 3edzed near London (Beddington Zero Energy Development Fossil) that aims to be ;arbon neutral show. Its power consumption does not exceed 40% of an equivalent area 'normal."

The designer Bedzed, Bill Dunster, tightened the links between housing, shops and )ffices, he voluntarily mixed. This urban design would have the advantage of meeting he housing needs of the British in the goal to build only on the Land without encroaching on agricultural or natural areas.

The French architect Jacques Ferrier envisioned a tower project "Hypergreen" high of tbout 250m for Lafarge: natural ventilation, solar electricity, everything is done to ninimize energy use (70% less). This project in particular was considered to Shanghai. It is distinguished by the available space for gardens between the facade and interior ;paces.

2. Self Houses. There are housing projects operating to 100% autonomous and clean through the use of rain water, wind energy and, of course, sun. Thus, developed by English architect Bill Dunster, the house received an award and aims to be fully 'sustainable".

The architect Jean-Baptiste Barache designed a house 100% recoverable and bio assembly. Seeking to use only natural light, the house has openings for heating a greenhouse in winter and keep good weather in the summer. The windows are made of recycled wood, recovered on film sets. The house is not supplied with electricity. This allows the recovery of the natural light.

3. Districts and ecological cities. The architect Norma Foster goes on another scale and imagines a city with 0 impact in Abu Dhabi.

China needs to build 400 new cities by 2020 to cope with its rapid urbanization that requires him to stay 300 million rural. Beijing will therefore try to Dongtan new town planning approach. A "green city" which will recycle energy and water and can accommodate 500 000 people in 2040.

As one of the fashion trends in construction today, houses, neighborhoods and ecological cities offer a wide variety of forms and ways of saving natural resources and introduce a new way of life . They fit directly into urban projects long term and can be considered as an innovative and compelling perspective in sustainable development of our planet.
