The purpose of energy-autarkic habitats is to be independent of third parties concerning energy consumption for living. This material can be based and resource-efficiency respective material, living space and energy. Autarky can be defined as the quality of being self-sufficient. As a self-employed person, it is morally only for the sake of doing “good”, independently of other incentives. In the past, people have had to live with a certain degree of self-sufficiency in their lives. network of proving these needs has been established (craft, trade, profession). In times of the industrialization which led to a destiny of dependency but made live “easier”. Nowadays there is a trend “back to the roots” – being independent of coal, renewable energy (wind, sun, water, wood).

Even in antic times people thought of energy-efficient living and tried to optimize conditions. By orientation to the winter sun as it is possible to heat up the wind, the wind forms, the compact forms with the less surface.

An Igloo is a habitat with a compact form that has a small surface area (compare the low energy form of a drop of water; This results in lessening the wind and reducing the cooling of the building. The igloo contains an airtight shell, which helps to keep the temperature inside constant. Concerning heating is relatively small volume to heat (as mentioned above, volume-surface-ratio).

A peat house provides, similar to the igloo, a compact form with the surface and hence less exposure to the wind. It also shows a near air shell with good heat insulation (peat). An optimized orientation to the sun adds additional degrees during the day.

Log houses have the same advantages as mentioned above. The material wood offers a good heat insulation and a good airtightness can be achieved by filling the gaps with moss and clay.

Monte Rosa Cabins mark a milestone in high alpine building presenting a high degree of energy autarky of over 90%, meaning that it is needed locally from renewable sources. The technical systems are based on existing technology (combined heat and power unit, photovoltaics, thermal collectors), innovative wastewater treatment (for the wastewater is going to be purified on-site to be reused as greywater) and foremost an ingenious energy management, which takes Intake of the autarky.

The basis for Mikrohaus is 8.80 × 3.44 × 3.25 cubic meters, which makes it possible for a modular assembly system to multiply and expand. The cube (s) do not have any fundamentals (only screws of 1.40 m length) which allows some kind of mobile living. It is required. Additional floats can also be installed on water. The photovoltaic (PV) energy supply. The cubical form allows a good ratio of volume to surface. The concept includes wastewater treatment for greywater via wastewater treatment plant with an ultraviolet light (UV) treatment unit for sanitary water. Additional planted walls (www.gruenwand.at) are used outside (for cooling / summer, insulation / winter,

Autarc homes provides the first generation of passive and self-sufficient guests. The swimming and rotatable passiv-house has its own on-board energy generation, water supply and disposal. The idea is to provide a sustainable, energy-efficient, environmentally compatible and affordable living space. The building can be oriented to the most possible effect out of it. As this building is located on the water is very energy efficient. The tasks are decentralized energy supply and storage, decentralized effluent disposal and recycling / reprocessing and drinking water supply.

Life on our planet is a permanent energy flow between living things and the environment. Most of the currently used energy resources, such as oil, coal, natural gas and uranium are non-renewable. The supply of them buried in the earth is limited and we are using them at a rapid pace. Renewable energy resources such as Solar energy, wind energy, small hydropower (eg Swimming hydroelectric power plant), geothermal energy and biomass fuels are becoming increasingly attractive. Solar, Photovoltaics, water and wind energy do not send pollutants into the air as it occurs with coal and petroleum energy. Hydrogen storage (storage by hydrogen) The objectives are to store H 2 in solid metal hydrides from which it is possible to recover from an alternative and safe, high volume efficient storage method.
