Building prediction and control theory have been drawing the attention of many scientists over the past few years because design and control efficiency consumes the most financial and energy. In the literature, many methods have been proposed to achieve this goal by trying different control theorems, but all of these methods face some problems in correctly solving the problem. The Evolutionary Bat (EB) Algorithm is one of the recently introduced optimization methods and providing researchers to solve different types of optimization problems. This paper applies EB to the optimization of building control design. The optimized parameter is the input to the fuzzy controller, which gives the status response as an output, which in turn changes the state of the associated actuator. The novel control criterion for guarantee of the stability of the system is also derived for the demonstration in the analysis. This systematic and simplified controller design approach is the contribution for solving complex dynamic engineering system subjected to external disturbances. The experimental results show that the method achieves effective results in the design of closed-loop system. Therefore, by establishing the stability of the closed-loop system, the behavior of the closed-loop building system can be precisely predicted and stabilized.

This study was performed to construct the spatial systems and shape grammars in architecture based on Froebel's educational idea and building gifts. Especially, it studies on the geometrical principles of Froebel's building gifts and it's types, and then illustrates applied examples about design vocabularies, spatial relations and shape rules of the spatial systems and shape grammars in architecture. The conclusions of this study that starts these purpose are as follows. First, Froebel's educational theory is based on principles and rules which are perceived through the observation of nature, and Froebel's kindergarten method consists of geometrical building gifts and categories of geometrical forms. Second, the characteristics of Froebel's building gifts are mathematical size, proportion, symmetry and the rules of spatial relation. Third, the development to the construction of spatial systems and shape grammars in architecture focus on the vocabularies of architectural elements, and Froebel's building gifts are used for illustration of examples in these formula.

In this study, attempts to analyze the case study of production design were carried out through: 1) exploration of the factors influencing the interface between architectural and production design phases; 2)application of precast technologies. Building design and construction planning in Japan may be characterized by ample use of Production Design which extends over the whole projects phases. Taking a composite construction system for apartment buildings which allow for alternative combination of different technologies as a case study object, three projects have been chosen to analyze actual process of determining product sub-system and their specification. And the expectancies of this paper are that it can be used as efficient data for improvement of system to systematize Constructability(Buildability) in korea.

The symmetry is general geometric design principal in contemporary architecture shape. But, Symmetry sometimes easily causes unreasonable design. In some reason, two of symmetric units in the apartment, one side of unit have very reasonable plan and arrangement but opposite side unit nay not. For example, if the kitchen on right unit had right-handed arrangement, the symmetrical other would have left-handed kitchen arrangement. In addition to this, if each house unit has the same plan but different direction, each unit has different usage or affects the residents' life pattern. Nevertheless, Architects use only one unit plan to design public housing development by using symmetric operator (mirror, proper rotation, inversion center) at their option. This study suggests that using group theory and mathematical matrix rather than designer's discretion can solve this symmetry problem clearly. And, this study analysis the merits and demerits between each symmetrical pair of unit plan shapes by using mathematical point group theory and matrix.

The purposes of this study were to compare Louis I. Kahn and Rem Koolhaas, both of whom established their architectural theories and granted rationality to them by applying the theory of psychoanalysis, and examine common and different characteristics in the inner space composition of a building between them. The study also set out to confirm a basic premise based on which to develop a metaphysical design concept by applying the theory of psychoanalysis in the inner space composition of contemporary architecture in future from the more developed and integrated perspective of modern psychoanalysis. As a result, Kahn sought after a metaphysical design concept through the combinations of inner unit spaces including servant and served space, which are comparable to the confrontation between consciousness and unconsciousness from the perspective of psychoanalysis. Unlike him, Koolhaas applied the concept of folding to his architectural plans based on the theory of post-structuralism and created a metaphysical design concept by more focusing on connections between unit spaces rather than their combinations. While Kahn worked on his designs with much interest in the combinations of inner unit spaces in horizontal circulation by separating it from vertical circulation, Koolhaas created a new design concept beyond the limitations of Kahn, who had a confronting, dichotomous view of the world between the phenomenal world and the metaphysical world, by making use of inclined slabs to connect upper slabs with lower ones. The findings show that there can be various metaphysical design concepts depending on how to connect and combine two confronting concepts when applying the theory of psychoanalysis to architectural design.

The first attempt in architectural design theory to consider the perceptual and metaphysical dimension separately with a fully modern scientific manner, which exist in contrast to the Renaissance idea, was Claude Perrault, who emphasized the cognitive factors as an important scientific human issue in building design in 1683 in his book "Ordonnance". Even today many elaborated works to reveal the mysterious design processes based on a set of rational approaches have been introduced since the Design Method movement in 1960's. Their pioneering and challenging efforts to rationalize design process have been mostly rely on the cultural issues whether it takes a qualitative or quantitative stance. On the other hand, however, today's computer generated free form architecture seems not to be aware of those lessons learned from the past and, therefore, this study conducted an extensive research through exploring on morphological building forms with cultural issues to fill up the missing and/or lacking characteristics of today trend in building design.

The fire safety design of performance is fire behavior inside buildings must be scientifically described and systemized as a theory, thereby allowing application to fire safety design of buildings. In this study, experiment of fire behavior according to disposition of combustibles were performed for correlation analysis between flashover and smoke production rate in building structure. As a result, smoke production rates is happened more than 80 m2/s in compartment(ISO 9705). Also, even if the fire load for flashover to if occur smoke did not, which confirmed that the delay time of occurrence.

The purpose of this study is to clarify the difference between design and construction conditions based on theory for support (S) and infill (I) distinction and separation in long-life housing, and to search for future direction. To do this, the SI theory is summarized and the construction situation is examined in the demonstration house and the differences and limitations are analyzed. In order to realize SI separation in Korea, it is necessary to set the position of pipe shafts for sewage and drainage, buried in the structure and Ondol layer of the private pipes, buried various wires in the inner wall, and fixing the position of the inner wall.

It has been known that one-dimensional rod theory is very effective as a simplified analytical approach to large scale or complicated structures such as high-rise buildings, in preliminary design stages. It replaces an original structure by a one-dimensional rod which has an equivalent stiffness in terms of global properties. If the structure is composed of distinct constituents of different stiffness such as coupled walls with opening, structural behavior is significantly governed by the local variation of stiffness. This paper proposes an extended version of the rod theory which accounts for the two-dimensional local variation of structural stiffness; viz, variation in the transverse direction as well as longitudinal stiffness distribution. The governing equation for the two-dimensional rod theory is formulated from Hamilton's principle by making use of a displacement function which satisfies continuity conditions across the boundary between the distinct structural components in the transverse direction. Validity of the proposed theory is confirmed by comparison with numerical results of computational tools in the cases of static, free vibration and forced vibration problems for various structures.

This paper attempted to analyze the Sainte-Chapelle(1242-48) in Paris in terms of Gottfried Semper's theory of four elements. For this aim, this study was divided into two parts: the first part regarding Semper's theory, which included not only the theories of four elements and four technical arts but also the concepts of the two types of primitive dwellings; the second part regarding the Sainte-Chapelle, composed of the overall study and the characteristics of the building and finally the analysis of it in terms of Semper's theory. The Sainte-Chapelle was regarded as a real example of Semper's four elements, in that the building was composed of a sacred altar containing Christ's earthly relics, stereotomic bases made of stone, a tectonic structure featuring linearity, and textile stained glass as an elaborate enclosure. While the bases and the structure were employed as serving elements, the altar and the stained glass played critical roles to make a whole space immaterial and monumental. These two elements served to reveal not only biblical typology but also the religious and political vision of Saint Louis to establish Paris is as a new Holy Land.
