The toilet in school building is one of most crucial elements for the recent changing face in school design, but the number of toilets and urinals in most school may not be sufficient to meet current needs, especially in the girl's toilet rooms. This study aims to suggest a guideline in designing the toilet in school buildings and propose the optimum area and development of models. The survey for this study is conducted through questionnaires collected and research from 9 schools in Seoul. The results of this study, it is suggested that the number of toilet facilities in school buildings be required by ratio of 0.5 toilets per a class and 1.1 urinal per a class for boy. In case of girls, it is suggested that ratio of 1.6 toilets per a class. Based on the result, it also propose various unit plans for each class block with space such as rest zone, green zone, powder zone etc.

High-rise buildings are increasingly viewed as having both technical and economic advantages, especially in areas of high population density. Increasingly taller buildings are being built worldwide. Increased heights entail increasing flexibility, which can result in serviceability problems associated with significant displacements and accelerations at higher floors. The purpose of this paper is to present the concept of a versatile vibration control technology (MR dampers with bracings) that can be used in super tall buildings. The proposed technology is shown to be effective, from a serviceability point of view, as well as resulting in dramatically reduced design wind loads, thus creating more resilient and sustainable buildings.

Tall buildings are one of the most viable solutions to deal with the global phenomenon of rapid population increase and urbanization. While tall buildings are an essential building type to accommodate ever-growing urban population, as buildings become very tall they also produce many critical design challenges related to social interactions, emergency egress, structural systems, etc. While many different design solutions can be sought to resolve these challenging issues of tall buildings, this paper investigates potential of conjoined towers in producing more livable and sustainable megatall building complexes with an emphasis on their capability in efficiently providing exceedingly tall building structures.

This research suggests the most effective way for improving energy efficiency in tall buildings is a "fabric-first" approach. This involves optimizing the performance of the building form and envelope as a first priority, with additional technologies a secondary consideration. The paper explores a specific fabric-first energy standard known as "Passivhaus". Buildings that meet this standard typically use 75% less heating and cooling. The results show tall buildings have an intrinsic advantage in achieving Passivhaus performance, as compared to low-rise buildings, due to their compact form, minimizing heat loss. This means high-rises can meet Passivhaus energy standards with double-glazing and moderate levels of insulation, as compared to other typologies where triple-glazing and super-insulation are commonplace. However, the author also suggests that designers need to develop strategies to minimize overheating in Passivhaus high-rises, and reduce the quantity of glazing typical in high-rise residential buildings, to improve their energy efficiency.

Achieving sustainable spaces is one of the emerging trends of tall buildings regarding their significant impacts on the cities. Reducing energy consumption and material using is investigated as a widely used approach to achieve more efficient tall buildings. Defining more efficient geometries and form modifications have been adopted for this goal. In this paper the effect of plan shape and diagrid angle on structural efficiency of diagrid tall buildings have been studied. A parametric workbench is applied to generate and analyze models. The goal is to find effective form parameters resulting in more efficient forms. Respectively, all models were generated in Rhino/grasshopper architecturally and analyzed by a finite element plug-in structurally. Based on the results, steeper angles almost cause more displacements and needs to be more stiffened. it can be seen almost more sided models need less weight for the structures and it could lead to more efficient forms.

This study aims to present the applicability of wind turbine generator system to urban buildings for the utilization of clean renewable energy. The results are as follows; According to the wind resource analysis, it has been found that small sized wind power system can be viable for buildings application due to the amplification of wind velocity around buildings or building clusters, in spite of low mean velocity of 2-3m/s in Seoul and Kyunggi urban areas. But planners must perform micrositing analysis around building so that wind turbine can be located at high velocity zones. The system must be designed to avoid obstacles preventing prevailing wind in buildings. It should be recognized that wind speeds are changing depending on the height and length from buildings. The wind power system can be used as a symbol of landmark which shows a sustainable architecture from the scenary Itself A case study for apartment building in urban showed that wind power systems can be applicable in two kinds of place, rooftops and ground levels. Especially, the wind power systems must be carefully positioned so that wind resources do not decrease when it is installed at ground levels. and according to life cycle cost analysis, adaption of new small win4 power systems to buildings were proved to produce a profit if it is considered the expense of environment improvement and the wind speed increasing according to rise of building height. This research will ultimately achieve green architecture that preserves nature and at the same time provides pleasant environment to humans, and will play a great role in establishing the environment-preserving sustainable architecture of the 21th century.

As urbanization increases in UAE, the demand for housing and infrastructures also grows. The challenge is to continue to build but in a different way considering more energy-efficient sustainable buildings. Producing a sustainable design is highly dependent upon effective participation among the diverse parties involved. In the construction industry in the UAE, these parties are fragmented due to the multistage nature of construction projects and multidisciplinary participants, particularly during the design stage. The decisions made during this stage have an extensive impact on subsequent stages of a project's life cycle. Having a sustainability expert during the design stage is important and the awareness of sustainability requirements by all design participants is of equal importance. In this research, recent advances in information technology are used to develop an information model that will improve the sustainability of building during the design stage. An information framework for storing design information and sustainability performance criteria is developed, allowing design participants to collaborate in an integrated environment. This research is expected to help designers produce sustainable designs for building projects.

With the increasing movement towards sustainable construct on, environmental rating systems (ERSs) came into use in the Middle Eastern (ME) region as similar to many other regions. ERSs were first developed to assess buildings and many ERSs have tended related ERSs. Despite the vast infrastructure development in the ME region and in the United Arab Emirates in particular, there is no understand the regional-specific requirements to attain sustainable construction and infrastructure. Tis research addresses these pags and study the theoretical underpinnings of sustainable infrastructure in the region, to propose a regional-specific, infrastructure-related ERS. This paper examines the underpinning factors of sustainable infrastructure in the UAE through a literature review in order to provide insights to determine criteria and subcriteria for the ERS.

Public buildings as a public space of the community have a close relationship with local residents and urban space. Public buildings are not a simple role as office space, but closely related to the life of the local residents. In addition, a variety of approaches, spatial, and program elements should be considered. Rising awareness for public buildings recently, aspect of design also has began to be interested. Small building is a public building that can actively cope with the social and economic environment in the rapid change. However, small building is lacking the design consideration according to the scale and economics. This paper is to present the Design Indicator that can be used to create 'small public buildings' that has been alienated from the large public buildings design development. This is intended to derive and utilize the design categories and design detail indicator of small public buildings. There are composition of design categories and design detail indicator of developed small public buildings. Design categories have developed six such as Public and Harmony, Access, Landscape Design, Space, Sustainable Design, Technique and Performance. Design Detail indicator of Small public buildings have developed all 24.
