Regeneration of abandoned industrial facilities can heighten the availability through potential values that cannot be found in newly-built buildings and through the sense of overscale space. Furthermore, backward regions can be activated by assigning their identity and establishing social-cultural infrastructures. The aim of the present study is to analyze and integrate of characteristics of design expression based on a case of creative space in Shanghai. A research on the creative space in Shanghi designedly proceeded according to government's extensive administrative support and policy. We keep appearances of industrial buildings as close as possible to their original condition, thereby revealing symbolism and forming unique characteristics that distinguish them from those of other areas. While keeping the shape characteristics of the bridge8, M50, Red Town, 2577 Greative Garden and 1933 Shanghai, we designed spaces in terms of spacial variability, oneness, accessibility and continuity and activated areas by inducing residents' participation and fostering art and cultural oriented facilities. These characteristics of design expression are factors to be considered in regenerating abandoned industrial facilities internally and hopefully they are used as a reference of design plan.

Windows are widely used for natural ventilation of the various buildings. Especially high level windows as a part of industrial ventilation systems, play a crucial role in natural ventilation. Compared to mechanical ventilation system, natural ventilation has the advantage of lower installation and operating costs. In general, high level windows for industrial buildings have three types; louver type, 45$^{\circ}$ open type and 90$^{\circ}$ open type. Based on previous studies, it was found that the louver type and 45$^{\circ}$ open type are very effective in reducing rainwater penetration, but they did not have enough ventilation efficiencies. Preliminary tests were performed with the various types of windows. It was found that a 90$^{\circ}$ open double layer type window was the best among those which tested in our preliminary tests. Simulated rain was used to estimate the amount of rain penetrated through windows and to observe the paths of rain penetration. Various 90$^{\circ}$ open windows were tested to find the windows with minimum rain penetration and maximum ventilation efficiency.

The wind-induced transient response of internal pressure following the creation of a sudden dominant opening during the occurrence of high external pressure, in low-rise residential and industrial buildings was numerically investigated. The values of the ill-defined parameters namely the flow contraction coefficient, loss coefficient and the effective slug length were calibrated by matching the analytical response with the computational fluid dynamics predictions. The effect of a sudden i.e., "instantaneously created" windward opening in the Texas Technical University (TTU) test building envelope was studied for two different envelope flexibility-leakage combinations namely: (1) a quasi-statically flexible and non-porous envelope and (2) a quasi-statically flexible and porous envelope. The responses forced by creating the openings at different time leads/lags with respect to the occurrence of the peak external pressure showed that for cases where the openings are created in close temporal proximity to the peak pressure, the transient overshoot values of internal pressure could be higher than the peak values of internal pressure in the pre-sequent or subsequent resonant response. In addition, the influence of time taken for opening creation on the level of overshoot was also investigated for the TTU building for the two different envelope characteristics. Non-dimensional overshoot factors are presented for a variety of cavity volume-opening area combinations for (1) buildings with rigid/quasi-statically flexible non-porous envelope, and (2) buildings with rigid/quasi-statically flexible and porous envelope (representing most low rise residential and industrial buildings). While the factors appear slightly on the high side due to conservative assumptions made in the analysis, a careful consideration regarding the implication of the timing and magnitude of such overshoots during strong gusts, in relation to the steady state internal pressure response in cyclonic regions, is warranted.

The purpose of this study was to analyze and compare the characteristics of floor plan of Underwood hall, Appenzeller hall, and Stimson hall in Yonsei University. These buildings in Yonsei University are the representative higher educational institution buildings that were constructed by Western missionaries during the Japanese colonial period. These buildings were designed by the master plan that had been made before the construction. Therefore, these buildings have many similarities but each building has individual characteristics. This study focused on two parts. One is the characteristics of the shared space, such as like corridor, hall, and stairs. These characteristics show the differences between each building because they used different methods and locations of shared space and rooms for the floor plan to include the different functions. The second is the relationships with the floor plan and other plans like the master plan, elevation plan, and structural plan. These relationships show that each building has unique characteristics that are related to the floor plan.

The Goon-rearrangement in 1914 caused a significant change in the Goon office buildings' construction in the Japanese colonial period. The aim of this study was to discover the administrative procedure for the construction of them around the Goon-rearrangement and also in the 1910s generally, the Japanese government-general's policy for the construction and the buildings' condition. This study analyzes the official documents for the Goon-rearrangement between the Japanese government-general of Korea and the To, the digital images of the buildings kept in the National Archive of Korea and the newspapers published in 1910s. This paper examines what the effect the construction had under the stance of the Japanese government-general of Korea, which was very passive regarding the construction of new buildings.

BIM technology has been used in the domestic AEC field since the middle 2000s. BIM has proved its worth in cutting-edge buildings, mega-buildings and freeform buildings in particular. Many freeform buildings could not be completed due to the low level of construction technique. However, many successful cases emerged after adopting digital technology, including BIM which encouraged architects to challenge freeform designs. The modeling software that can generate the freeform shape are not usually able to build the efficient BIM data type in the AEC industry. In this study a process model of the parametric freeform construction member generation and conversion to BIM data is shown and the prototype system is demonstrated.

Efficiency and universality which was the spirit of the modern age, had also an enfluence on our living environment. Various types of individual housing unit were developed and mass-produced. However, the exterior space in our city is a place for our social life and intermediate place to connect the private life of each individual to our society. For the people to adapt themselves well to their environment, it should be well organized which means it is clearly divided and integrated in a hierarchical order. To realize these conditions, adequate boundaries to divide each territory and entrances to connect each territory are two essential elements. One of the possible methods to realize these conditions can be found in korean traditional architecture where the exterior space has the same figural quality like buildings and is the center of the whole composition. Buildings, walls and colonnades are the elements to define space. Gates, pavilions, gabs between buildings and posts are the elements to symbolize the entrance connecting each space. Each exterior space is integrated to a whole composition. One is the gradual differentiation along the axis which is unique in korean traditional architecture. The other is the rectangular connection which is also found in the other area in the world. The results of this thesis are as follows. The exterior space in the housing area should have the figural quality. The elements to make boundaries defining exterior space are classified into horizontal elements such as low buildings and walls, and vertical elements such as tower-shape buildings which define space in a different way. The position of openings in a housing block affects the characteristic and openness of a exterior space. Various types of gates are used to decide the relationship between spaces.

Recently, studies of vibration control performance improvement of tall buildings connected by a sky-bridge have been conducted. In this study, the effect of difference of natural vibration periods of two buildings and install location of a sky-bridge on vibration control performance has been investigated. To this end, 40-story and 50-story building structures were selected as example structures. Analytical models were developed by varying the natural period difference ratio from 1.0 to 1.5. Artificial earthquake load based on KBC2009 was used as an excitation for time history analyses. Based on numerical simulation results, it has been shown that control performance for displacement and velocity of tall buildings connected by a sky-bridge is improved as the difference of natural periods of two buildings increases and the linked story becomes higher. However, in the case of acceleration response, it shows a counter trend compared to displacement and velocity responses.

As abnormal climate phenomena frequently happen due to the after-effect of the global warming, all nations suggest climate change response policies in many different fields to prevent global warming by reducing greenhouse gas. Especially, these days, the realization that the greenhouse gas from city buildings should be decreased is growing, and it is because that buildings are accounted for a quarter of national greenhouse gas emission and it is more than half the percentage of emissions within the city. Accordingly, Korean government sees the need to take an initiating role to fulfill low-carbon green policies and promotion strategies in the public sector, and wants to facilitate greenhouse gas reduction in the private sector as well. In this background, this study tries to examine the low-carbon planning element in public buildings and figure out the amount of carbon reduction and economic analysis centering Cheongju city as case study. Lastly, we propose some suggestion for low-carbon and greening of public buildings.

The vibration control performance of a semi-active damper connected to adjacent buildings subjected to seismic loads was investigated. The MR damper was used as a semi-active control device. A fuzzy logic control algorithm was used for effective control of the adjacent buildings connected to the MR damper. In the buildings control coupled with a MR damper, the response reduction of one building results in an increase in the response in another building. Because of these conflict characteristics, multi-objective optimization is required. Therefore, a fuzzy logic control algorithm for the control of a MR damper was optimized using a multi-objective genetic algorithm. Based on numerical analyses, the semi-active fuzzy control of MR damper for adjacent coupled buildings can provide good control performance.
