“Sustainable building”

The principles:

To achieve sustainable architecture should be taken into account;

• The construction site and environmental assessment.   
• Guidance and passive energy use.
• Construction systems.
• Building Materials healthy.
• Energy consumption.
• Waste generation and recycling.

Building materials:

With regard to materials, we say that the degree of sustainability is related to the construction zone. It is necessary to know the natural resources of each place and the extent to which these can be renewed.

Although, there are some materials which generally can be categorized as organic, as it relates to natural products widely existence. Like adobe, bamboo, earth, clay bricks, ferrocement, construction lime and pozzolanic cement.

Adobe: it is a brick made from clay. The ideal mixture contains 20% clay and 80% sand. These materials, mixed with water, are becoming more fluid way to dump into wooden forms to the size wanted. When the water evaporates, the brick is capable of sustaining itself, remove the form and complete the drying in the sun. Full cure takes about 30 days. This is when the brick is as strong as concrete.

Bamboo: bamboo rods are of a type of grass can vary in height from 30 cm to 40 meters, according to the American Bamboo Society. " Grows in different climates, from jungles to the slopes of the mountains.

In some Asian countries this material has been used for centuries as building material for houses, cooking utensils, etc.

Lime: Lime is a versatile and excellent binder and has a long tradition as a construction material for agricultural use and sanitation. Although it has been largely replaced by cement, lime offers many benefits and in Europe is regaining its status among builders. Lime can be produced locally in many parts of the planet, but they should emphasize fuel efficiency and the cooking process.
