On the threshold of the 21st century, the paradigm of the city planning began to be shifted from the efficiency-focused functions towards environment and sustainability. In the past, housing complexes were built as many as possible due to the rapid urbanization with the focus on efficiency and economy, despite such serious environmental problems as global warming, air pollution, water pollution and increasing wastes.
Since the UN Environmental Conference held in Brazil in 1992 which declared 'a sustainable development', each nation has been more and more concerned about the environmental-friendly buildings conducive to reduction of the environmental loads, while researching into them actively. In Korea, Ministry of Environment and Ministry of Construction and Transportation have been operating 'the Environmental-Friendly Building Certification' system in response to international community's concerted efforts, while Korea Land Corporation has suggested a guideline titled 'Eco-Environmental City Development Handbook' for housing site development.
The purpose of this study was to analyze the environmental-friendly factors for the housing redevelopment plans and thereby, suggest the ways to improve them. For this purpose, the researcher comparatively analyzed their environmental-friendly planning factors in reference to 'Environmental-Friendly Building Certification' system (for apartment houses) and 'Eco-Environmental City Development Handbook' and thereby, arranged the criteria for assessment of the environmental-friendly buildings. Based on these criteria, the researcher sampled 3 apartment housing complexes of each development type (n=12) in Seoul and the capital area which were occupied after 2000 and therewith, assessed their environmental-friendly factors. As a result, it was found that 'the environmental-friendliness certified housing complexes' were most excellent, followed by 'apartment housing complexes planned and developed', 'ordinary apartment housing complexes' and 'redeveloped apartment housing complexes' in their order. On the other hand, as a consequence of surveying residents for their satisfaction with their living environment, it was disclosed that the certified environmental-friendly apartment houses were prices about 20% higher than the other complexes.
In addition, the researcher used the above criteria to analyze the environmental-friendly factors of the sample apartment houses and thereby, reestablished the criteria applicable to 4 eco-environmental sectors which might well be neglected: land use plan, pedestrians' and vehicles' circulation, residents' amenities and eco-environment. Then, the researcher sampled 'Nangok Redevelopment district' in Seoul occupied in 2006, because it was deemed to represent the redevelopment districts in Seoul and thereupon, analyzed its environmental-friendly factors in reference to the reestablished criteria. As a result, it was found that it was poor in 3 sectors: 'pedestrians' and vehicles' circulation', 'residents' amenities' and 'eco-environment'.
Lastly, it was conceived that if a system should be operated to reflect the environmental-friendly planning factors, more environmental-friendly apartment housing complexes would be developed or redeveloped.
