Abstract
This article proposes a new idea of the selection of number series for the sizes of building components in metric system, which are called not to be concidered significantly without relating sizesi n the system to measurements of the human body. The principal series is of the limited odd numbers; 1, 3, 5, 7, 9, 11, 13 and it is developed by combining the doubling and haloing of the principal series, therefore it has Simplification and correlation which is essential for the modular coordination. Moreover, by rearranging this limited series through the method of decimal repetition, it presents the complete ranges which consist of four or six Fibonacci Series; IM-33, IM-42. First in these Fibonacci Series is based upon the dimension 180cm, optimum height of a man, and extends in both direction from this size, the second contains the doubling series of the above-mentioned series. Both coinaides approximately with "Le Modulor" by Le Corbusier. It is sure that they have enough the necessary simplicity that would allow them to become second nature to the architect and contribute to the rational industrialisation of components. The last four series are also of Fibonacci Series, they contain the approximate Φ number; 1.6, of which they say the proportion of the human body. Generally speaking, these series provide for decimal repetition, arithmetic progressions, geometric progressions; doubling, haloing, tripling, and the introduction of the number Φ, moreover the coincidence with the human scale. As a result, components with measurements based on these sizes can be placed on a module reference gride corresponded with the human body, and the sum of a number of components can be equal to another larger component. At last, this article contains the comparisons with the most frequently used sizes in Japanese products, and with the "Renard Number" R40, R50. DΦ-series & GM-series.
