A) HISTORY :Less 10 approximately 000 years, at the end of the glaciation of WURM, the man already homo-sapiens seeks his food in continual displacement. It is the time of the dwellings light, traced in extreme cases of surface necessary to its activities and consisted of a thin and light but essential wall to protect itself from the bad weather, (because it lost its fur while being protected from skin garments during terrible the the 600 000 last years glaciations). No concept of straight line or angle governs the layout of its shelter. All is curved around him: self-centredness reinforced by the instinct of self-preservation of the survival of the Dés species at the time poses the problem of the report/ratio of the man to his dwelling Depuis, it will not cease improving the techniques of its habitat by taking account of the parameters of its existential reality. It will be initially the sedentarisation requiring the storage of the food products and the tools, then the urban centre (stage " tortoise ") accumulating of richnesses coveted by the wandering hunters reducing to poverty itself by the food scarcity. Finally the fortifications which will be the container of an urban growth being compressed more and more by creating the " Carréisme " after having passed by the " mosaic " stage

After the unification of the large countries, the obsolete fortifications do not confine any more the city, and appears a new financial organization capitalizing and developing industry. Already started by the demographic growth, the rural migration will develop and continue human compression, by centripetic aspiration. It is the time of the land higher bid developing the conquest heights where flower the buildings and the turns. There, rejected with the periphery, the populations pullulate in stacking where régne the " Carréisme " more organized and most constraining of all times.

Then appear contradictions, source of already known social distortions of old. Psychological faintness, cancellation of the concept of wall and especially of territory, social stress developing the anguish, narcotic self-destruction, delinquency and by-products: racism and violence. It is the effect " Bronx " where whole districts are devastated, plundered and reduced to the state of ruins by collective aggressiveness. Here the phenomenon of compression reaches almost its paroxysm while starts the favoured urban exodus by pollution, and the financial conditions of subsistence (squaterisation).

B) SEEKS AND DEFINITION

• Dimensioning curves livable volumes .
• The thorough study of the motionless human stature (organic statics) and moving (organic dynamics) highlights the rotundity of the obstruction of the human body.
• The analysis and the classification of the activities practised by the man in his habitat stress the concentric form of their organization.
• Displacement between the various activities shows the sinuosity of circulations.
• The whole of these observation determines the " flow chart " true nervous system surface and volumetric of a livable space.
• The limits reached by this livable space is curved, it is the return to the original curved dimensioning practised since the Neolithic era.
• The construction of a wall around this space requires, if one wants to respect his configuration, an adapted technology.
• The whole of this search led us to study and develop walls to simple horizontal and vertical curve, and to S curves concave (spherical and derived) and reversed (hyperbolic parabola)La put in practice technical such walls confirms the simplicity and the effectiveness of the implementation; moreover the unit of volumes thus carried out present of the very interesting characteristics and brings an often effective solution to questions raised by the " carreism " and remained until there without answers.

C)CARACTERISTIQUE AND ADVANTAGES

Characteristics :Elimination of discontinuity enters the wall and the roof cancelling the concept of wind-bracing.

• Para-seismic resistance because of this geometrical continuity.
• Resistance to the parameter snows and wind by an effect of aérodynamisme very strongly improved
• Possible para-cyclonic resistance for the public buildings.
• Reduction in the obstruction visual in the environment
• Technological simplification by the unification of the technique of construction.
• Multiplicity of the methods for realization.
• Car-construction more largely favoured.
• Possibility of industrial prefabrication of great series.

Advantages:a) Techniques :Diminution of the quantity of materials implemented (very significant)

• Reduction in the weight up to 80 % allowing the reduction of the foundations
• Use of the grounds hitherto a41dernier $c-b1,e,10 $c-b26 ce $c-b16 $c-b43,bn,84 inconstructibles (escarpés or too pieces of furniture)
• Reduction in the surface of built wall from 25 to 35 %
• Coefficient of form very clearly improved from 20 to 40 %
• Sealing definitely higher than water and the air Maintenance facilitated by the absence of heteroclism of the technique and the suite materials

  précédenteb) Thermal Reduction in the loss:

   

  - By the reduction in the surface of wall (approx. 40 %) - By the linear reduction (peripheral report/ratio minus 25 % env) - By the reduction in volumes of stratifications Reduction in the power of heating installation (env. 50 %) solar Facility of heating... The absolute record was reached by a curviform dwelling in Drome: 2,6 kg/fioule/m2/an (average main road 18 kg/fioule) - Financial Process ARCHA c) Reduction in the cost of construction from 15 to 80 %

   

  - Dome hull ferro-concrete minus 15 % - Dome hull plasters less 30 % - Dome hull industrialist minus 50 % - geodetic Dome drink less 60 % - Dome tries (yourte) less 80 % the continuation belongs to the future, but already from the hundreds of million men will be born from here year 2000 and the habitat cannot be defined any more as in the past, modelled by
