After the concept of apartments was introduced in 1960s in Korea, on account of the development of architectural technology and science, high-rise residences in Korea are getting higher, and these residences have been becoming high-rise commercial/residential buildings since 1990. Nowadays, as the construction of high-rise commercial residential building complex is booming, the difference between these complex and high-rise apartments is getting smaller, and these two kind of high-rise residences are becoming new residential style in Korea. And these high-rise residences are considered the symbol of wealth owing to the marketing strategy emphasizing high quality, refined interior, a fair view, and the protection of privacy. However, high-rise residences bring about many problems related to health and psychology caused by the consumption of a large amount of energy, pollutant emission, the deterioration of the quality of indoor air, and vibration. For this reason, in this study, we tried to emphasize the necessity of environment-friendly access to provide healthy living environment and to reduce the negative effect of housing life in high-rise residences, and find the method to improve environment-friendly quality and health of residents in interior space. Therefore, this study aims to detect the problems and the items to be improved of interior spaces of high-rise residences by quantitative, qualitative analysis of the evaluation elements and the floor planning elements deduced from environment-friendly architectural certification in Korea and the other countries, and suggest the guideline to improve the environment-friendly quality of these interior spaces.

This study is an attempt to quantify rainwater utilization and miscellaneous water demand in Tokyo's 23 special wards, the core of the urban area in Tokyo, Japan, in order to elucidate the potential of further rainwater utilization. The rainwater utilization for miscellaneous appropriate water demands, including toilet flushing, air conditioning, and garden irrigation, were calculated for six different types of building: residential house, office, department store, supermarket, restaurant, and accommodation. Miscellaneous water demands in these different types of building were expressed in terms of equivalent rainfall of 767, 1,133, 3,318, 1,887, 16,574, and 2,227 (mm/yr), respectively, compared with 1,528 mm of Tokyo's average annual precipitation. Building types, numbers and its height were considered in this study area using geographic information system data to quantify miscellaneous water demands and the amount of rainwater utilization in each ward. Area precipitation-demand ratio was used to measure rainwater utilization potential for miscellaneous water demands. Office and commercial areas, such as Chiyoda ward, showed rainwater utilization potentials of <0.3, which was relatively low compared to those wards where many residential houses are located. This is attributed to the relatively high miscellaneous water demand. In light of rainwater utilization based on building level, the introduction of rainwater storage mechanisms with a storage depth of 50 mm for six different types of buildings was considered, and calculated as rainfall of 573, 679, 819, 766, 930, and 787 (mm), respectively. Total rainwater utilization using such storage facilities in each building from 23 wards resulted in the retention of 102,760,000 $m^3$ of water for use in miscellaneous applications annually, and this volume corresponded to 26.3% of annual miscellaneous water demand.

Ground-coupled heat pump(GCHP) systems have been shown to be an environmentally-friendly, efficient alternative to traditional cooling and heating systems in both residential and commercial applications. Although some work related to performance evaluation of GCHP systems for commercial buildings has been done, relatively little has been reported on the residential applications. The aim of this study is to evaluate the cooling and heating performances of a vertical GCHP system applied to an artificial detached house($117\;m^2$) in Seoul. For this purpose, a typical design procedure was involved with a combination of design parameters such as building loads, heat pump capacity, borehole diameter, and ground thermal properties, etc. The cooling and heating performance simulation of the system was conducted with different prediction times of 8760 hours and 240 months. The performance characteristics including seasonal system COP, average annual power consumption, and temperature variations related to ground heat exchanger were calculated and compared.

Currently, the environmental certification such as BREEAM and LEED has been improved for the sustainable development and related research is conducted continuously. Especially, in the respect of economy, it is reported that the construction costs of the certified buildings are more increased than non-certified buildings. However, the report has not focused on the educational building but the residential and commercial buildings. Therefore, the objective of this study is to analyze the difference of construction costs between LEED and Non-LEED educational buildings. To achieve the objective, the buildings data are collected in 21 universities then T-test is used for examining the construction costs. As a result, it shows that the construction costs of LEED buildings are increased by 3.8% comparing with non-LEED buildings.

Heat release characteristics of live fire load are an important parameter for performance oriented fire safety design of a building. While investigations have been carried out on the fire load and its burning behavior in office, residential and commercial buildings and so on, little effort has been paid for the rational treatment of fire load in post office buildings in Japan. In this report, burning behavior of typical combustible objects in post office buildings are studied by measuring heat release rates of plastic palettes with and without postal envelopes or packages and special containers loading numbers of palettes. The test results suggest that dynamic heat release rate is highly dependent on the condition of palettes especially if they load appropriate amount of postal envelopes or not.
