Human factors is the most important components of Green Architecture besides the main approach of energy consumption and preservation. That factors are reflected by introduce comfort and healthy spaces , Which suitable for human occupation both physical and psychological. The article concern the relationships of Green Architecture with nature first: as a crucial natural system , second as a natural appearance or views. The work study is concern the style of Green building of Japan architect Nikken Sekkei , Who used the concepts of Japan Traditional Architecture with new technical approach. The conclusion is that the suitable sustainable technical in Green Architecture is by unit and immerge the natural element (sun light and heat-wind flow-earth temperature)as new tools in steps of design process .

Growth is presented as one of the important properties which distinguishes flexible compositions .This property emerges in the middle of twentieth century in some architectural trends as a reaction towards a problem facing the designers, considering the production of compositions that can face rapid changes in design requirements over the time with preserving their architectural identity, however the architecture is a convertible phenomena. The article discusses the importance of this property and how it is achieved in architectural products. The framework of this paper consists 0f one main item (devices 0f achieving growth in flexible compositions) which determine growth ,firstly, then the application of this item on a sample 0f specialized architects , secondly ,finally ,extracting comprehensive description of that property in architecture. Conclusions have been declared, that growth is achieved by employing both formal and structural characteristics, considering cellular geometric shape with many similar fragments or cells which can expand and spread horizontally and vertically like organs, concentration on the principle of similarity (uniformity) in composing the fragments , with articulation as compositional relationships, as well as applying hidden orders based on modular clustered-grid composition ,traditional structure and zoning space system.
