Shipping container architecture is a form of architecture using steel intermodal containers (shipping containers) as structural element, because of their inherent strength, wide availability and relatively low expense.

Strength and durability
Shipping containers are in many ways an ideal building material. They are designed to carry heavy loads and to be stacked in high columns. They are also designed to resist harsh environments - such as on ocean-going vessels or sprayed with
road salt while transported on roads. Due to their high strength, containers are useful for secure storage.

Modular
All shipping containers are made to standard measurements and as such they provide modular elements that can be combined into larger structures. This simplifies design, planning and transport. As they are already designed to interlock for ease of mobility during transportation, structural construction is completed by simply emplacing them. Due to the containers' modular design additional construction is as easy as stacking more containers. They can be stacked up to 12 high when empty.

Transport
Pre-fabricated modules can also be easily transported by ship, truck or rail, because they already conform to standard shipping sizes.

Superadobe is a form of earthbag construction  hat was developed by Iranian architect Nader Khalili.
The technique uses layered long fabric tubes or bags filled with adobe to form a compression structure. The resulting beehive shaped structures employs arches, domes, and vaults to create single and double-curved shells that are strong and aesthetically pleasing. It has received growing interest for the past two decades in the natural building and sustainability  movements.
Many different materials can be used to construct Superadobe. Ideally you would have barbed wire, earth or sand, cement or lime, and Superadobe polypropylene tubing (available from Cal-Earth); bags can be polypropylene, or burlap. What is important is that they are UV resistant or else quickly covered in plaster. Virtually any fill material will actually work including un-stabilized sand, earth, gravel, crushed volcanic rock, rice hulls, etc. If the fill material is weak the bags have to be really strong and UV resistant, or else plastered right away.

Cob, cobb or clom (in Wales) is a building material consisting of clay, sand, straw, water, and earth, similar to adobe. Cob is fireproof, resistant to seismic activity, and inexpensive. It can be used to create artistic, sculptural forms and has been revived in recent years by the natural building and sustainability movements. Cob is an ancient building material, that may have been used for construction since prehistoric times. Cob structures can be found in a variety of climates across the globe.
Cob is an old English word for "lump". It refers to lumps of earthen material that are sculpted together to form walls or other features. This is a truly ancient building material, one that can be found (or variations thereof) across the globe and spanning back thousands of years. The benefits of cob are many, and like many of the other materials in the natural builder's toolbox, can be integrated into a structure to take advantage of its strength and beauty in a non-toxic, low-impact, inexpensive, user-friendly way.
Being primarily made of earth, cob is as inexpensive as the soil from which it is made; if this happens to be material pulled out of the site during excavation, it could well be that your investment in a cob wall is little more than a load of sand and some bales of straw. Quite simply, cob is made by mixing clay-rich soil &mdash or if not available, pure clay — with sand, adding in loose straw, and hydrating with water to get the desired consistency. Cob can be thought of very much along the same lines as plaster when analyzing the nature and function of its ingredients.

Adobe is the original solar-powered building material. Sun-dried bricks of MUD and STRAW make adobe one of the most abundant and lowest energy materials around. The wobbly walls of an adobe home hold a charm and romance that evokes the spirit of the desert of the American Southwest. Adobe is perhaps the oldest building material, dating back thousands of years. Mud-brick buildings have been found all over the world, particularly in the Middle East and North Africa. The word adobe can be traced back to the Ancient Egyptian word for mud brick from 2000 b.c. The Great Depression of the 1930s brought widespread attention to adobe construction. The U.S. government sponsored adobe construction projects across the country, particularly in the Dust Bowl regions of the Southwest and Midwest. The low-skill method of forming and stacking mud bricks quickly caught on in these areas. The heat-absorbing qualities of adobe made it the perfect choice for the hot, dry climate. Many of these Depression-era homes are still in use today.Adobe brick manufacturers have made a science out of adobe production. A careful mixture of MUD, CLAY, STRAW, and WATER is poured into a wooden frame (like a mold) and left to bake under the SUN. The molds are quickly removed and the bricks are dry in a matter of hours. Dung is often used as a stabilizer and natural insect repellant. Once dry, the manufacturer sends the finished bricks out for construction.

Rainwater harvesting is the accumulation and storage of rainwater for reuse before it reaches the aquifer. Uses include water for garden, water for livestock water for irrigation etc. In many places the water collected is just redirected to a deep pit with percolation. The harvested water can be used for drinking water as well if the storage is a tank that can be accessed and cleaned when needed.

Rainwater harvesting provides an independent water supply during regional water restrictions, and in developed countries is often used to supplement the mains supply. Rainwater harvesting systems are appealing as they are easy to understand, install and operate. They are effective in 'green droughts' as water is captured from rainfall where runoff is insufficient to flow into dam storages. The quality of captured rainwater is usually sufficient for most household needs, reducing the need for detergents because rainwater is soft. Financial benefits to the users include that rain is 'renewable' at acceptable volumes despite climate change forecasts, and rainwater harvesting systems generally have low running costs, providing water at the point of consumption.Benefits of widespread rainwater harvesting to the regional reticulated supply system may include reduced treatment, pumping, operation and augmentation costs, reducing peak storm water runoff and storm water processing costs, as well as reduced greenhouse gas emissions due to reduced dependence on pumping and potential augmentation through sources such as desalination  The concentration of contaminants is reduced significantly by diverting the initial flow of runoff water to waste. Improved water quality can also be obtained by using a floating draw-off mechanism (rather than from the base of the tank) and by using a series of tanks, with draw from the last in series. The stored rainwater may need to be analyzed properly before use in a way appropriate to its safety.
Rainwater harvesting systems can be installed with minimal skills. The system should be sized to meet the water demand throughout the dry season since it must be big enough to support daily water consumption. Specifically, the rainfall capturing area such as a building roof must be large enough to maintain adequate flow. Likewise, the water storage tank should be large enough to contain the captured water. Rain water harvesting is possible by growing fresh water flooded forests without losing the income from the used /submerged land.  The main purpose of the rain water harvesting is to utilize the locally available rain water to meet water requirements throughout the year without the need of huge capital expenditure. This would facilitate availability of uncontaminated water for domestic, industrial and irrigation needs.

A renewable resource is a natural resource with the ability to reproduce through biological or natural processes and replenished with the passage of time. Renewable resources are part of our natural environment and form our eco-system.
Renewable resources are endangered by industrial developments and growth. They must be carefully managed to avoid exceeding the natural world's capacity to replenish them. A life cycle assessment provides a systematic means of evaluating renewability. This is a matter of sustainability in the natural environment.
Solar radiation, tides, winds, geothermal, biomass and other natural elements are renewable resources of energy now called renewable energies.Gasoline, coal, natural gas, diesel and other commodities derived from fossil fuels, as well as minerals like copper and others, are non-renewable resources without a sustainable yield.
Solar Energy is the most easily available source of renewable-energy. The solar rays emitted by the sun are a non-quantifiable and available for use both directly and indirectly. The ideal tool to convert the intangible solar energy into a usable energy is the photovoltaic cell. Concentrated solar power (CSP), is another effective way to convert sunlight into electricity, this technique focuses on taking the sun’s rays and placing it into a liquid that heats up and produces steam that spins an electricity producing turbine. This process uses reflective dishes that direct the sun’s rays to get the maximum energy.The Sun yearly delivers more than 10,000 times the energy that humans currently use. This energy if harnessed can be used for a number of other more simplistic uses. A number of activities that are part of the daily lives of almost everyone’s life can be altered to take advantage of the abundantly available solar energy. Of these, the most simplistic use would have to be solar cooking. Solar-cookers according to a research done in Costa Rica can play a crucial part in curbing deforestation as well as excess carbon emissions. Another innovative tool that takes advantage of the available solar energy are the solar heaters. Again, instead of relying on carbon-emitting non-renewable sources of energy, the solar heaters effectively and efficiently manage to use solar energy to heat up water for domestic as well as commercial uses. Such simple yet innovative techniques play an important part in the daily lives of those individuals that are deprived of the conventional sources of energies such as electricity.

Wind is the movement of air across the surface of the Earth, affected by areas of high pressure and of low pressure. The surface of the Earth is heated unevenly by the Sun, depending on factors such as the angle of incidence of the sun's rays at the surface (which differs with latitude and time of day) and whether the land is open or covered with vegetation. Also, large bodies of water, such as the oceans, heat up and cool down slower than the land. The heat energy absorbed at the Earth's surface is transferred to the air directly above it and, as warmer air is less dense than cooler air, it rises above the cool air to form areas of high pressure and thus pressure differentials. The rotation of the Earth drags the atmosphere around with it causing turbulence. These effects combine to cause a constantly varying pattern of winds across the surface of the Earth. The total amount of economically extractable power available from the wind is considerably more than present human power use from all sources.
Wind power is the conversion of wind energy into a useful form of energy, such as using: wind turbines to make electrical power, windmills for mechanical power, windpumps for water pumping or drainage, or sails to propel ships.Large wind farms consist of hundreds of individual wind turbines which are connected to the electric power transmission network. Offshore wind farms can harness more frequent and powerful winds than are available to land-based installations and have less visual impact on the landscape but construction costs are considerably higher. Small onshore wind facilities are used to provide electricity to isolated locations and utility companies increasingly buy surplus electricity produced by small domestic wind turbines.Wind power, as an alternative to fossil fuels, is plentiful, renewable, widely distributed, clean, produces no greenhouse gas emissions during operation and uses little land Any effects on the environment are generally less problematic than those from other power sources.
A wind farm is a group of wind turbines in the same location used for production of electricity. A large wind farm may consist of several hundred individual wind turbines, and cover an extended area of hundreds of square miles, but the land between the turbines may be used for agricultural or other purposes. A wind farm may also be located offshore. Almost all large wind turbines have the same design — a horizontal axis wind turbine having an upwind rotor with three blades, attached to a nacelle on top of a tall tubular tower. In a wind farm, individual turbines are interconnected with a medium voltage (often 34.5 kV), power collection system and communications network. At a substation, this medium-voltage electric current is increased in voltage with a transformer for connection to the high voltage electric power transmission system.

LED Technology

  • High efficiency, energy saving by up to 80% Its life expectancy is 17 times higher than the common fluorescent of (6.000 h). It can last up to 100.000 hours
  • White lights
  • Low requirements of voltage and consumption
  • No UV radiation
  • Can be easily controlled and programmed
  • Different types with different levels of radiation
  • High levels of flow and directed intensity
  • Water resistant; perfect for photo-voltaic (solar panels) systems, in comparison to any other type of actual technology
  • The usage of LED lights is quite possibly the most profound change the illumination sector has made since the invention of the electrical light. LED lights are transforming the nature of illumination, opening up new possibilities in ways to use artificial lighting.LED technology, also known as Cold Light, is said to be the biggest illumination revolution since Edison’s invention of the electric bulb, and could eventually replace the conventional light bulbs used up to this point in time. Up until now, these bulbs generated a conventional filament base in which 90% of the energy was transformed into heat and vanished. LED technology shines upon a crystal, where energy is directly converted into light.Incandescent light bulbs (which contain Xenon and Krypton) lose 90% of their energy when converting to heat. With LED, the total energy is transformed into light which considerably reduces the emission of heat produced by the greenhouse effect on Earth.Economic savings; Due to the low power consumption and long lifetime of LEDs, one hour of use costs .001 of a cent.Decrease in repairs: Uninterrupted, LEDs have a lifespan of about 11 years, so they are no longer in need of spare parts, compared with conventional lamps, which only guarantee a 60-hour use.
    Shock resistance: The glass does not shine like a filament, is located inside a clear plastic lens (without glass), so it can be dropped, thrown or climbed over without damaging the car.
    Environmental Conservation: The lower power consumption reduces battery demand, reducing the amount of toxic waste they produce. No mercury (which upon exposure to the environment is highly poisonous) in comparison to fluorescent technology or magnetic induction that contains mercury like the low consumption CFL, for example.
    They emit diffused light, providing numerous benefits to a range of ten meters. Thus, the spaces are lit more evenly without sharp contrasts or 'rings' of light, allowing better orientation and perception of details. The blue light is generated (an effect of "daylight"), so that our night vision is less affected than traditional lighting, offering a better view and perception of depth and detail. Since it resembles sunlight, if projected against a wall in the daylight, one can concur that it does not seem as powerful as a classic yellow light. However, doing the test in the dark is where you really appreciate the great difference in light.

    Light from the sun is a renewable energy resource which provides clean energy, produced by solar panels. Today, solar panels and complete solar panel systems are used to power a wide variety of applications.

    Solar energy, which is also often called "solar power", is energy which comes from the Sun in two forms of radiation: HEAT AND LIGHT. These two forms of radiation are generated from the fusion of helium and hydrogen inside the Sun. Humans on Earth can capture this radiation and use it to create hot water and steam in the case of heat (greenhouse effect) and we can use it to create electricity.

    Each of these two forms of solar energy requires the manufacture of two separate types of solar panels. One is called a "SOLAR COLLECTOR" which is used to heat water and then store it in a tank for distribution when needed. The other kind of panel is called a "SOLAR PANEL", or more formally, a "PHOTOVOLTAIC PANEL".

    Solar panels collect the light radiation from the Sun and convert it into direct current electricity, which can then be converted to alternating current using an inverter. A solar panel (also known as a photovoltaic module) is a device that converts photons of light from the Sun and converts them into an electric current.

    An average home has more than enough roof area for the necessary number of solar panels to produce enough solar electricity to supply all of its power needs. Assisted by an inverter, a device that converts the direct current (or DC current), generated by a solar panel into alternating current (or AC current), solar panel arrays can be sized to meet the most demanding electrical load requirements. The AC current can be used to power loads in your home or commercial building, your recreational vehicle or your boat

    No longer is it necessary to pay huge fees for the installation of electric utility poles and cabling from the nearest main grid access point. A solar electric system is potentially less expensive and can provide power for upwards of three decades if properly maintained. Besides the fact that solar panels make it possible to live off-grid, perhaps the greatest benefit that you would enjoy from the use of solar power is that it is both a clean and a renewable source of energy. With the advent of global climate change, it has become more important that we do whatever we can to reduce the pressure on our atmosphere from the emission of greenhouse gases. Solar panels have no moving parts and require little maintenance. They are ruggedly built and last for decades when properly maintained.

    Last, but not least, of the benefits of solar panels and solar power is that, once a system has paid for its initial installation costs, the electricity it produces for the remainder of the system's lifespan, which could be as much as 15-20 years depending on the quality of the system, is absolutely free! For grid-tie solar power system owners, the benefits begin from the moment the system comes online, potentially eliminating monthy electric bills or, and this is the best part, actually earning the system's owner additional income from the electric company. How? If you use less power than your solar electric system produces, that excess power can be sold, sometimes at a premium, to your electric utility company!
