 materials13Building materials have changed a lot over the past 50 years.  In recent years the term "green" has been coined for the use of building materials that are better for the environment.  There are many different ways that things can be better for the environment, there are materials that used recycled products, there are things that use less energy to run then they used to, and there are things that have been introduced into the building community that basically uses no resources from the environment at all.

Building materials that are considered "green" are materials that have a low impact to the environment.  These materials are often fast growing plants like bamboo, that means that it grows back quickly, and can be used again in a short time.  Other materials are that are considered environmentally friend would be listed below.  These are actual materials that can be used to build the framework of the home.  That consists of the outside walls, the slab of your home, and other parts of the skeleton of the house being built.

  • Ecology blocks - Are large blocks of concrete that have a groove across the Ecology blocks are good because they can be reused.bottom side of them and a hook on the top so you can move them with machinery.  These blocks are often used to make walls for retaining earth.  These are considered environmentally friendly because they can be taken down and used somewhere else, where concrete walls that had been used have to actually be torn down to be dismantled.  Ecology blocks are also used with remaining concrete left in the mixer trucks after they are done at a job.

  • Dimension stone - This stone is all natural and Dimension stone is cut from quarries all over the country.can be used in many different applications of the building process.  The "green" part of this is that it is all natural so all that has to be done is to cut it.  Other materials that this can replace like concrete, aluminum, and steel all have to be manufactured with cause air, and water pollutants.  They are also considered green because they can be recycled and reused where as the other materials can''t be reused most of the time without having to be processed again.

  • Compressed Earth Block (CEB) - Is a block that goes through a process of Compressed earth blocks are made right at the job site.using earth, non-expandable clay, and a aggregate and compressing it with a machine to make blocks for walls of homes.  Though this way is very environmentally friendly it can only be done in areas that do not see much rain.  Areas like New Mexico, Arizona, California, Colorado, and some in Texas.  One good thing about this is that the earth that can be used is usually at the actually building site, and if the concentration of water to earth is right it can go straight from the pressing machine to the wall.  This saves in shipping costs and pollutions.

  • Adobe - This is another form of natural building materials, this is a form of Adobe bricks are dried from the sun, and adobe mud is applied to home and then dried by sun.concrete but it can be used from all natural materials.  It uses sand, clay, water, and some kind of fibrous material like straw, sticks, or dung.  This is then formed into bricks and laid out in the sun to dry.  Like CEB this is normally used in fairly dry areas because water can compromise the integrity of the brick.  These types of buildings are found in the Middle East, South America, North Africa, and Southwest United States.  Besides being made from natural resources the other benefits of Adobe is that they have a larger thermal mass then other forms of wall materials.  Thermal mass is the ability of the material to absorb the heat or cold from the outside so that it is not transferred to the inside of the building.

There are other materials that can be used to build the outside walls of buildings, but they are a lot like the methods that are mentioned above.  These other types are baked earth, rammed earth, and clay.

Green roofs started in Europe and are becoming more popular in the United States.There are other parts that can be green on the outside of your home.  Many new things are being tried to make buildings and homes more "green".  This includes the roofs of many homes and buildings around the world.  These are called green roofs, it is a process where people put sod on the roof of homes and buildings to make them more environmentally green.  Green roofs have been used in Europe for centuries but is gaining popularity in the United States.  Homes in Northern Scandinavia have been around for centuries, and the modern version started in the 1960''s in Germany, it''s not said that about 10% of all homes in Germany have green roofs.

Green roofs have a lot of environmental benefits, although it may need patches sometimes and some maintenance it doesn''t need to be replaced like shingled homes.  GreenChicago''s city hall has a green roof roofs also add to the insulation of the home, the roof will absorb most of the heat that is generated from the sun, and that will lower your energy bills considerably.  Green roofs are becoming more popular in major cities in the United States because of the advantages of heat displacement.  The Chicago City Hall Building has a green roof and is normally 25 to 80 F cooler then other traditional tar roofs.  The other advantages that people have noticed are that you can grow other things on green roofs like vegetables, and fruits.  These are usually done in cities where there are flat roofs or homes that have been built recently with the green roofs being planned in the building process.
