With the increased demand on housing quality and effective urban redevelopment, a new paradigm in reconstruction project is in need. Especially, the Urban and Residential Environment Improvement Law which initiated on July 1, 2003 has become a significant turning point. This code is expected to function as a consistent and systematic measure. This study will examine the code's major concepts and methods to progress reconstruction projects effectively. The application of construction management is examined carefully since the new code requires renewal project consulting firms to function as a professional complement rather than simply perform administration work, as in the past. Also, construction managing methods that can be related to renewal project consulting are examined and speculated. Lastly, methods to improve efficiency in reconstruction projects are introduced through case study and analysis on applicability and expected results.

Performance improvement of local exhaust system used in toilet and cooking place are main concern in a field of ventilation. In Korea, There are many high riser residential apartments in recent years. These buildings were not viewed as being major contributors to exhaust pollutants producted in indoor. It was because many engineers thought that exhaust in high riser building depends on stack effect. This study investigates on the performance improvement of terminal device, roof fan, of vertical spiral duct used in high riser residential apartments. This paper focuses mainly on the effect of accessories, number or shape of blades, composed of roof fan with function of exhaust air volume of toilet and cooking place. Roof fan with 10 blades is observed at optimum exhaust performance in this study.

For the improvement of the cultural rural village(new rural village project), it is very important to find the various planning alternatives. The purpose of this study is to suggest the ideas which are able to be applied to the rural site planning. The YoungMoon project site located in Kyunggi province was selected case study, The followings are suggestions developed in the process of preparing an alternative plan for the case study. 1) The preparing of the rural site plan is the organizing process of the planning ideas responsive to the condition of both a project site and the project directions. 2) In developing the schematic plan, it is very useful to introduce the cluster madang (small public open space) including 25 houses as a basic planning unit. 3) In comparison with the project plan, the alternative plan presented by this study has advantages of amenity and public space of the residential environment of the new rural village. It is properly said that we have to more and more discuss the best solution to take in planning the rural site, and this efforts contribute the improvement of the quality of the new village project.

This study investigated the construction and operation status of sewer pipes and water-purifier tanks near densely populated areas like large apartment complexes, in order to find out cause for offensive orders. The study results revealed that the main cause arose from the water-purifier tank and public sewer pipes near ordinary residential areas. First, in case of independent water-purifier tanks, the air is forced into the rotten part of large tanks nearby which should be operated in an anaerobic state, so that the tank changes into an aerobic state, or dirty water, which is returned during the sludge return process, falls on the top of the rotten tank, preventing scum from forming within the tank. Such problems cause incompletely purified water in the purifier tank to be discharged, which in turn results in filthy water. Second, in case of public sewer pipes, deteriorated or aging pipes, or the mixture of rain water and dirty water by mixing up combined and separated sewers system can cause foul odors in residential areas. Therefore, offensive odors in residential areas can be radically reduced through the appropriate construction and management of facilities including water-purifier tanks. As well, if more separate sewers are installed as part of an improvement project for public sewer pipes, complaints about foul smell can be minimized.

As horizontal expansion of a city reaches the uppermost limit, on the ground of perpendicular expansion and efficiency of land use, skyscrapers go on increasing in number. However, skyscrapers which were newly built in Korea have many problems such as consumption of enormous amounts of energy, destruction of natural environment, and traffic jam. And from now on, environment-friendly development of skyscraper is urgently needed. Therefore, in this study, we tried to find the planning elements and estimation indexes to improve the environment-friendly quality of high-rise residential architecture by investigating environment-friendly skyscraper certification in Korea and the other countries. For that reason, we investigated the application ratios of 10 cases in Korea. And the results showed that the application ratios of environment-friendly estimation indexes were lower than 50% and the environment-friendly quality of skyscrapers in Korea was generally low. Therefore, based on these planning elements and estimation indexes, we tried to establish the guideline of improvement direction for environment-friendly development of high-rise residential architecture in Korea.

The residential space of super high-rise buildings, having a form of a huge three-dimensional vertical city, affect the residents psychologically and qualitatively according to the line of flow. Because of these affects, the system of the line of flows is a very important factor. In this study, we recognize the super high-rise apartment's line of flow as a semantic network system based on case studies. And we also understand the mutual relationship by analyzing each space to recognize what effect it does on the residential environment. Furthermore, to bring up a better semantic network system for super high-rise apartment's line of flows is our goal. According to the case studies, the semantic network of the line of flow consists of 3 parts: the functional network, economical network and unit network. The functional network is composed of the 'need' and 'has', while the economical network includes variable walls that can be changed following the user's taste and eccentric positioned living rooms that protect personal privacy. Therefore the economical network started to appear while the personal value changed according to the improvement of the social condition. Finally, the unit network is a network that effects each unit that has ambiguous boundaries due to the appropriate arrangement between transitional spaces. And the unit network is based on the functional network.
