Domestic hospital architectures were developed with the nation's industrialization after 1960s. Particularly, with the rapidly growing healthcare demands according to The National Health Insurance Plan which was introduced in 1977 and expanded to entire nation in 1989, the number of healthcare facility is also increasing according to the expansion of the existing facilities and construction of new buildings. Now, twenty to thirty years were past since that growing period of healthcare architecture. Many hospitals are facing on the phase of restructuring and modernization for their resources. J university hospital is a representative case of hospital development which the growth of facility was stopped by insufficient site area. This study, analysing its past statistics and drawing data of that hospital, presents the characteristics of the changes and basic data of the master planning for the future hospital development.

Seismic retrofit of an existing steel-reinforced concrete hospital building that features innovative use of a continuous energy-dissipative steel column (CEDC) system is presented in this paper. The special system has been adopted to provide an efficient solution taking into account the difficulties of applying traditional intervention techniques to minimize the impact on architectural functionality and avoid the loss of building function and evacuation during the retrofit implementation. The lateral stiffness and strength of the CEDC system were defined based on the geometric and mechanical properties of the steel strip dampers. The hysteretic behavior under cyclic loadings was defined using a simplified numerical model. Its effectiveness was validated by comparing the results of full-scale experimental data available from the literature. All the main design considerations of the retrofitting plan are described in detail. The effectiveness of the proposed retrofitting system was demonstrated by nonlinear time-history analyses under different sets of earthquake-strong ground motions. The analysis results show that the CEDC system is effective in controlling the deformation pattern and significantly reducing damage to the existing structure during major earthquakes.

The current hospital buildings try to support the functional needs and the social requests that is proper for so fast changes of the society. The historical changes of the hospital is affected by many direct or indirect factors as same as the societal changes. The factors of the changes are so various as the aspect of the disease, the development of medical care, the medical system, the medical facility, the social demands and so on. This thesis aims to investigate the historical traces of the ancient hospital wards through factors related to the changes therefor it will be known what factors affected to the changes of the ancient historical hospital wards. Finally it will be not only presupposed a proper counterproposal to the changes of a future hospital scope, but it will be also known the history of the hospital wards.

China is prone to earthquake disasters, and the higher seismic performance is required by many existing civil buildings. And seismic evaluation and retrofit are effective measures to mitigate seismic hazards. With the development of performance-based seismic design and diverse retrofit technology for buildings, advanced evaluation methods and retrofit strategies are in need. In this paper, we introduced the evolution of seismic performance objectives in China combined with performance-based seismic design. Accordingly, multi-phase evaluation methods and comprehensive seismic capacity assessment are introduced. For buildings with seismic deficiency or higher performance requirements, the retrofit technologies are categorized into three types: component strengthening, system optimization, and passive control. Both engineering property and social property for the retrofit methods are discussed. The traditional seismic retrofit methods usually are costly and disturbing, and for example in Beijing, seismic strengthening costs approx. 1000 RMB/m² (for 160 USD/m²), for hospital building even more expensive as 5000 RMB/m²(for 790 USD/m²). So cost-efficient and little disturbance methods are promising techniques. In the end, some opinions about the retrofit strategy and schemes category are shared and wish to discuss the situation and future of seismic retrofit in China.

This research introduces necessity to derive new certification criteria for the hospital considering healing environmental factors in G-SEED. The method of research is reference study to discuss concept of healing environment factors and case study to find ways for problem and improvement by comparison of G-SEED with foreign certification system. And the research conclusion is such as follows. First, it is necessary to develop certification criteria of the hospital for G-SEED which is lack of healing environmental assessment factors unlike foreign certification system. Second, The hospitals are certified by criteria of The Other Buildings in G-SEED which dose not take into account the characteristics of the hospital. Especially hospital waste and use of enormous water are the important factors required, which is already evaluated in foreign certification criteria.

In many other buildings, hospital is very important because of its function and purpose. A proper building service systems including heating, cooling, ventilation and plumbing systems is required in hospial. Besides, a special systems like medical gas, vacuum cleaning systems are required to prevent contamination as well as cure a patient in hospital. Ventilation is very important method to keep the indoor pressure and clean class. There are some specific rooms to consider clean class and indoor pressure in the general hospital. In this article, specific rooms were set to operating room, laboratory, ICU, isolation unit, and sterilizer room. In this case study, design factors of ventilation system, including air changes of OA and TA, indoor pressure, clean class, filter, and material of system, of specific rooms in hospital were proposed through a literature research and a design examples review.

Space transformation of hospital architecture happens more rapidly than other types such as school and office buildings. This requirement is caused by medical demand, service transformation, technical development and equipment changes. Grand scale extension and rapid change in hospital architecture affects whole planning; therefore, it is important to design in the macro perspective such like Life Cycle. Grand scale extension is difficult process to rebuild growth and transfer of hospital architecture and to adapt to the future change. That's why simple planning gives limits to some departments in a short-term and brings another reform such as more extension or interior renovation in a long-term. This study surveys various space transformation and grand scale extension of EB hospital extended recently, and it is to find planning condition in extension.

Increase in oil prices and building energy consumption has been a great burden for Korea which has significant energy dependence on foreign energy sources. In this context, reduction of building energy consumption, which comprises 40% of total energy consumption, is a very important issue. This research therefore empirically analyzed a hospital "P" that implemented ICT-based energy consumption and cost reduction initiative. The hospital first replaced existing water absorber for heating/cooling air and boiler for heating water with water heat storage heat pump system. This was accompanied by subscribing to different electricity price plans to maximize cost reduction. Secondly, the hospital additionally applied ICT-based optimized control algorithm that considers surrounding factors (external temperature, changes in energy demand). The analysis of these mechanisms indicate that the ICT-based energy consumption and cost reduction initiative for hospitals can reduce energy consumption by 53.6% with replacement of low-efficiency equipment and additionally by 18.2% with optimized control algorithm. The mechanisms will provide energy consumption reduction opportunities for other hospitals and buildings with high energy consumption.
