Meaning of Green Building
“ Ecological construction ”, “ sustainable construction ”, “ bioclimatic architecture ”. All these concepts are related to an intelligent occupation of the built space in harmony with the environment. However, each one has its particularities and different approaches to work.
Although it has the same objective as the other concepts, it has a different strategy through the use of materials available on the construction site, in addition to advocating the integration of the construction with the landscape to cause the least possible visual impact.
Ecological architecture has as its main objective the use of materials available on the construction site.
These can be made in an artisanal or semi-artisanal way and that use, in most cases, renewable materials such as straw and vegetable fibers.).
An example of green building is the Eskimos using the ice, the Indians using the land, and various other examples of indigenous peoples who only had local resources.
It is almost a consequence that these buildings maintain an integration with the local environment, minimally interfering with the landscape.
Of course, no one will have to live in an igloo. Some examples of modern buildings that follow the concept of ecological construction can be seen in Germany, the United States and Mexico, for example.
Bioclimatic architecture has as its main focus the comfort and well-being of the resident / user through the adaptation of the construction to the local climate, generating a better use of energy.
Sustainable construction aims to reduce the environmental impact of construction through the use of less aggressive techniques, materials and technologies before, during and after work, which guarantee the sustainability of the company through the use of durable materials, the reuse of water and alternative forms of energy.
Ecological Construction Techniques
It is clear that the techniques have evolved and today, we have different options of materials and finishes that allow for a much bolder look than in the past.
In addition to greater durability, although the historic cities do not deny that these materials are already quite resistant.
In Germany, in the city of Weilburg, there is the tallest building in Europe built from raw earth (rammed earth).
With 7 floors, the building has already withstood a fire and is almost 200 years old.
Some other materials that can be used in ecological constructions are: wood, stones, adobe (raw earth blocks that do not go through the firing process of conventional bricks), cob (clay mixture with mixed vegetable fibers widely used in England), earth -cloth or just pressed straw in the form of blocks (straw), caulet (clay, lime, cement and vegetable fiber mixed), super adobe (adobe-type mixture stacked in polypropylene bags).
Each material requires specific care for its use and maintenance and offers different work possibilities.
In the same way as in sustainable construction , in ecological construction measures to save water use, energy efficiency and waste management cannot be lacking.
It is important to always observe if the materials used were extracted in a sustainable way (without deforestation and other degradations).
