The purpose of this study is to analyze patterns of public school building layout types, open space and relationship with communities in the Manhattan grid plan. The study illustrates how building layout patterns of school facilities are influenced by societal demands in the urban grid environment. During the nineteenth century, the Island of Manhattan was transformed into a physical representation of the Cartesian coordinate system via the development of the grid street plan. In order to take advantage of streets as urban space, it is quite important to understand characteristics of communities and open space relationships between buildings and streets. Moreover, the strategic planning of schools' outdoor space vitalizes public streets as a critical community anchor. This research reviews 118 Manhattan public schools and categorizes them by (1) building layout type, (2) site type, (3) circulation and public open space, which are the biggest factors that determine the layout patterns of the public schools in Manhattan. As a result of analysis, the layout patterns are classified into seven types : "ㅡ", "L", "ㄷ", "ㅁ", "H", "T" and "other" type. Of these, "ㅡ" type and "L" type occur most frequently, because these configurations most flexibly fit into the limited grid-locked blocks, the various types of site & topography, and adapt most dynamically to the open spaces created by using avenues and streets. The ultimate objective of this study is to provide a case study for future efforts to plan open spaces for campuses that effectively utilize the streets in proximity.

The performance of the daylighting in buildings depends on building site and shape. As an energy saving design strategy, daylighting is a key issue in green building design. In this paper, the influence of the adjacent or obstructed building on daylighting performance of the office building in urban area was analyzed. A typical office building about 20 storeys with obstructed buildings has been modeled and simulated using Radiance. The parametric simulations have been performed to analyze the influence of the daylighting performance (illuminance, luminance) of the analyzed office. The results show that the possibility of the glare was decreased when the obstructed building is located in south, also the illuminance level was significantly decreased. When the obstructed building is located in north, the changes of the illuminance level and luminance possibility were somewhat small compared to the unobstructed condition. The daylighting performance of the analyzed building was most affected by the obstructed building in winter season.

The fields of green building and ecological design have much to offer to those who are seeking to improve the ecological impact of schools and school grounds. These well established disciplines are particularly useful to existing schools considering renovations to make them more energy, water, and resource efficient as well as healthier places to work and play, Green building and ecological design principles and techniques are also very effective, of course, if incorporated into the design for brand new school buildings. The major concept of the Eco-school plan is to understand that the school consists of an ecosystem, so the design concept should focus on minimising impact but at the same time maintaining close contact with the environment. T his is becoming the basic concept in applying the Eco-school design to the new 21st century school building. This thesis is an analysis on the methods of application, based on careful examination of case-studies from the U.S.A about detailed plan element and design method, through the following six aspects ; (1) site use plan, (2) green plan, (3) water system plan, (4) materials and recycling of resources, (5) energy use plan, (6) indoor environment plan.

Traditional reinforced concrete slabs and beams are widely used for building. The use of flat slab structures gives advantages over traditional reinforced concrete building in terms of design flexibility, easier formwork and use of space and shorter building time. Deflection of the slab plays a critical role on the design and service life of building components; however, there is no recent research to explore actual deformation of concrete slab despite various advancements within the design codes and construction technology. This experimental study adopts the Hydrostatic Levelling Cells method for monitoring the deformation of a multi-storey building with flat slabs. In addition, this research presents and discusses the experimental results for the vertical deformation.

This study compared 24 newly-built elementary schools in Sejong City regarding the size of the site and school, as well as the outdoor space to improve the site and space programming in school planning. Among the others, one result indicates that the overall number of classes in a school should be reduced to 48, including the affiliated kindergarten, instead of the present number of 50. In addition, the number of classes must be counted in lieu of the number of student by classifying the size of school. In light of the present mean ratio of school building area per site in the city of 24.6%, which is much higher than other comparable city schools, the ratio should be about 20.0% by increasing the sports facility and outdoor spaces. In addition, the deprivation of the area caused by the district-unit-plan and the irregularity of the place should also be considered when determining the size of a school and site.

Construction industry has a relatively higher industrial accident rate than other domestic industries. Thus, to reduce the accident rate, researches on the methodology of worker's safety education combined with new technologies like IT technology have increased. In the light of workers' safety information provision, this study develops a VR(Virtual Reality)-based construction site using the BIM(Building Information Modeling) data. The target structures and geographical features are included in the VR-based construction site where the construction machinery model and worker model are also created using a game engine. For highly effective provision of safety information, video clips with suitable captions corresponding to working processes were made with proper screen directing. They should be appropriately connected to correct worker's operations to improve the work commitment level, sense of reality and inducement of interest. From this scenario, the 3D VR-based construction site, which can be experienced through a VR equipment, was created and in the same platform, the safety information was provided by the video clip combined with the suitable captions. Although the real construction site involves various requirements depending on field situation and the expertness and experience of workers are not consistent, the developed safety information provision based on the VR construction site is expected to effectively reduce the incomplete factors leading to construction accidents by improving the worker's perception of workplace safety.

As recent buildings have been enlarged and free-formed, it is hard to represent three-dimensional buildings with two-dimensional drawings and identify design errors, construction errors, difference of construction quantity and construction cost, clash with columns, beams, pipe machinery, and so on. In order to overcome the limitations, BIM(Building Information Modeling) has been used in construction industry. However, BIM in the construction site is not fully facilitated after practical implementation in process control including training, evaluation and analysis of the process. Therefore, in this study, the effect of BIM applied in the construction site is analyzed empirically throughout the survey at the construction site in accordance with the training, evaluation, and implementation of BIM.

In this study, in order to evaluate adequacy of considering local site effect, excluding soil-structure interaction (SSI) effects in inelastic dynamic analysis and design of mid-rise moment resisting building frames, three structural models including 5, 10, and 15 storey buildings are simulated in conjunction with two soil types with the shear wave velocities less than 600 m/s, representing soil classes $D_e$ and $E_e$ according to the classification of AS1170.4-2007 (Earthquake actions in Australia) having 30 m bedrock depth. Structural sections of the selected frames were designed according to AS3600:2009 (Australian Standard for Concrete Structures) after undertaking inelastic dynamic analysis under the influence of four different earthquake ground motions. Then the above mentioned frames were analysed under three different boundary conditions: (i) fixed base under direct influence of earthquake records; (ii) fixed base considering local site effect modifying the earthquake record only; and (iii) flexible-base (considering full soil-structure interaction). The results of the analyses in terms of base shears and structural drifts for the above mentioned boundary conditions are compared and discussed. It is concluded that the conventional inelastic design procedure by only including the local site effect excluding SSI cannot adequately guarantee the structural safety for mid-rise moment resisting buildings higher than 5 storeys resting on soft soil deposits.

The purpose of this study is to analyze the characteristic of common space of public schools in New York City and how the common space can perform a decisive role in enriching public space not as simply connecting between programs but as common space for a wide range of uses for communities as well as students. This study illustrates with a general design guideline of SCA(School of Construction Authority) and how the rules help the common space as an interactive link between community and site/site and school building/building and outdoor space/outdoor space and lobby in the urban context. Since its founding in New York City, 1958, Mitchell/Giurgola Architects office has dedicated itself to working with institutions and public and private schools for 50 years and has been working with SCA for 10 public schools since 1990. Through five school examples by Mitchell Giurgola architects, the study describes how the office suggests public "place" interweaving inner public space and outer public space through lobbies. A result of this research can be proposed what improvements should be made on common space in domestic schools by analyzing of positive aspects of SCA schools.

The purpose of this paper is to find out the factors affecting the apartment price given three sets of variables such as characteristics of apartment building, apartment site, and location. Data of 1,579 housing units in 224 apartment complex sites in Ilsan city were selected from the housing information of four public and private housing sources in 2006. The first set of variables for physical features include housing size (pyoung), preferring-floor, building orientation, heating system and structure of entrance. The second set of variables for building were number of housing units, built year and rank of construction company. The third set of variables for location were distance from number of school, the subway station, distance of department store and park. For the analysis, the hedonic price model, which was one of the methods to estimate social convenience, was used along with the SPSS statistical program and regression analysis. The results are as follows, Firstly, in the structural characteristic variables, it was analyzed that all of the variables except facing affected the apartment price. Secondly, In the site characteristic variables, unusually all of the variables were not affected the apartment price in Ilsan city. Finally, the locational characteristic variables number of school, the subway station, distance of department store and park affected the apartment price. In case of Ilsan city, educational facilities was likely to positively contribute to the price of apartment.
