  1. IAIA 07, Seoul The Promotion of Environmental Assessments concerning Urban Climate and Air Quality in Spatial/Land Use Planning in Seoul, Republic of Korea Jeong-Hee Eum Johann Köppel, Dieter Scherer, Ute Fehrenbach June 06, 2007 Berlin University of Technology, Germany

  2. Introduction Strategic Environmental Assessment in Korea • Since June 2006 • SEA = Prior Environmental Review System (PERS) • Framework Act on Environmental Policy • 13 environmental issues including meteorological characteristics should be evaluated in spatial / land use plans. Introduction Method Result Conclusion

  3. Evaluation relevant to Climate in PERS Evaluation Criteria • Meteorological data (e.g. wind speed and direction), which affect dispersion of air/odor pollutions • Effects of air/odor pollutions from the neighboring areas on the objective area • Meteorological changes caused by new developments Evaluation tools • Meteorological data measured with weather stations • Model simulation Planning-oriented criteria and spatially-distributed information for spatial planning are needed! Introduction Method Result Conclusion

  4. Concept Ventilation Air quality Thermal situation Planning-oriented Evaluation Criteria Spatially-distributed Information Ventilation • Maintain ventilation • Improve ventilation • Reduce risks of hazards caused by strong winds Air quality • Maintain transport of fresh air • Improve transport of fresh air • Reduce risks of air pollution Thermal situation • Maintain transport of cold air • Improve transport of cold air • Reduce risks of ther. pollution • Reduce frost risks / heat loss Introduction Method Result Conclusion

  13. Summary and Conclusion • Due to climate change in global level, increasing urban temperature is expected. • This study showed a way how the climatic elements can be evaluated for spatial/land use planning, concerning planning-oriented evaluation criteria. • The spatially-distributed information, such as climate analysis maps and planning-oriented information will enable SEA executors to consider the issue of urban climate and air quality in spatial planning more efficient than before.
