What is the ecological architecture
"Eco" is derived from the Greek Oikos, intended for "home" and "home" and later derived into the ecology (Ecology). The 20th century, 60's, the architect Paolo Soleri proposed "eco-building" concept so far, its meaning is constantly expanded and extended. It is now widely believed that the basic principles of ecological architecture is the application of ecological principles and methods of restraint use and transform nature. Find the most suitable for human survival and development of sustainable support for the environment; to the built environment as an organic, with the structure and function of the overall system to maintain.

Then pop some say that the so-called eco-building is to architecture as an eco-system, a huge number of the population living in a super-integrated architecture, through the organization (design) construction inside and outside the physical state space in a variety of factors, so that material, energy in building eco-cycle in an orderly manner within the system conversion, to obtain a high efficiency, low consumption, no waste, no pollution, the ecological balance of the built environment.
As the global environmental degradation, ecological problems have become more serious, there is growing concern about the survival of mankind itself means. Eco-technology play an increasingly important role as the countries to achieve sustainable development, green express and deliver the promised. Eco-technology is the use of the principle of ecology, a holistic approach that considered the issue, pay attention to the whole system optimization, comprehensive utilization of resources and energy, reduce waste and unnecessary wear and tear, with a smaller consumption will gain a huge goal to reasonable access to resources and energy, use, promotion of eco-environment in sustainable development.
Here are two ecological building design
1, New Orleans, "Noah" eco-architecture
A group of ambitious architect has designed a rebuilding in New Orleans called "Noah" ecological architecture, design covers an area of 3 million square feet (about 2.8 square kilometers), can accommodate 40000 people live, there are a range of environmental facilities.

Large-scale eco-building "Noah"

Noah's interiorIf you prefer, you can not out of Noah's life
As a representative of ecological architecture in New Orleans, Noah able to accommodate 2 million dwellings, three hotels and 1,500 timeshare units. A huge pyramid-shaped building in which residents can provide one-stop services to both the size of shopping centers, 8,000 parking spaces, as well as cultural space, schools, municipal facilities, government agencies, as well as health care facilities. If a person is willing to look, he can not out of Noah's life.

Although the sounds live in a building on a lifetime is not the pieces of interesting things, but Noah did when in the design, taking into account as fully as possible to meet the needs of the residents of the building aims to build to withstand hurricane hit, the hurricane had given this side of the Mississippi River city of considerable disaster. Noah's foundation can be floating, the main structure is hollow, so that's designed to make the hurricane no matter which direction attacks can damage the building will be approximately reduced to a minimum.

Positive
From the sustainability perspective, treatment of this very large building, people tend to skeptical, but in fact Noah's can accommodate a large number of residents, the number of the item is worth more than enough material consumption. Noah also to some extent reduce car use in urban areas, because people can be in a building to meet all needs, and the construction of the traffic mainly through the completion of horizontal or vertical lifts, you can say that it is a pedestrian's paradise. There are other environmental design and reliable wind turbines, water reuse and storage systems, air heating and cooling pipes parks, passive-type glass curtain wall, sewage treatment, solar arrays are built on the river's water power generation turbines, etc. . If you really like the designers said Noah can withstand hurricanes, there will be a truly sustainable development, the typical.
2, Calcutta Twin Towers Intercontinental
Calcutta Twin Towers Intercontinental, one of the main purpose of the project is toImproving the building location of eco-climatic conditions to improve the local environment. To this end, the project uses two sets of ecological strategy. First of all, to create different levels of walking garden. A variety of space, such as "walking city" "shopping center" "shop" is located in such a garden roof. To do so, on the one hand and created a beautiful environment, while a variety of space and because of this there is a roof garden becomes cool, reducing the use of air-conditioning system, saving resources. Secondly, the entire site was built within a cannot venue reservoirs, the entire site into two, providing fresh moist air, for a walk in which people with a beautiful garden scenery and comfortable eco-climate and environment.
Intercontinental Twin Towers project in Calcutta, another major objective is toMaximize the utilization of natural resources such as solar and wind power, reduce energy consumption. To create a set of eco-ring (one meter wide) around the building facade for the outside glass shade, absorb solar energy and photovoltaic cells generate electricity through the set. Ring 10 cm away from the glass facade, for the glass facade of the air to provide vertical circulation, reduce the cost of heat and air conditioning systems.

Intercontinental Twin Towers project in Calcutta and then a main purpose ofDesign of appropriate structuresTo achieve two purposes: 1. To reduce large area ratio - generally a large number of high-rise buildings using structural columns to create an effective cross-section. Calcutta, the structural design of the Twin Towers Intercontinental creative. Three main cylinder into a huge triangle, forming the main body of the vertical structure. Most of the elevators and stairs are located in these three pillars, each building of the three pillars of the locations are different.This structure for hotel formed a longitudinal atrium, while farmers need not atrium, tower of the entire structure so as to the center, the moving can provide better tower of co-management daylighting and ventilated. 2. For the construction to provide natural air circulation within the movement. Buildings in different regions around the main structure of the triangle, but the separation between the various regions, and can increase the natural light, while the internal courtyard to provide natural air circulation.
