South Korea and Germany differ in their climatic conditions and structural building properties. With the focus on residential buildings, both countries have different approaches to assessing and increasing resilience to heavy rain and summer heat and thus adapting to climate change.
The aim of the project is to identify the differences in climatological boundary conditions (monsoon in South Korea, more intensive heat waves than in Germany) as well as constructional features and based on this to point out corresponding risk potentials with regard to heavy rain and heat events.In addition, it will be demonstrated how the different countries proceed to reduce vulnerability. Finally, the effectiveness of summer heat adaptation measures will be analysed by means of thermal building simulation of a common Korean and a German multi-family house type.
Within the project, different climate adaptation measures representative for the climate conditions in Germany were analysed and summarised for the Korea Environment Institute (KEI) in Sejong, South Korea. The focus is set on summer heat, extended to heavy rain and flooding, which are increasing in intensity and duration in both countries, Germany and Korea. In sumemr 2019, a workshop between representatives of the IOER and the KEI took place in Dresden, Germany, where the KEI presented the requirements and the IOER presented the first results. At the end of 2019, the results were summarised in the English-language report entitled "Climate Change Protection and Adaptation in Germany regarding Summer Heat Waves and Heavy Rainfall" and submitted to the KEI. The KEI in turn integrated the results into its report "A study on how to provide land and building information considering climate adaptation" (1).
Within the project, it became clear that the two countries differ in terms of appropriate summer heat adaptation measures:
Accurate component analyses of Korean single- and multi-family houses were conducted, which were transferred to the building performance simulation. The detailed comparison of two reference apartment buildings, a representative 40-story high-rise building from Korea and a 5-story low-rise residential building from Germany, and the different effectiveness of climate adaptation measures to summer heat in Korean and German climate will be published in an English-language journal by mid-2021.
