Study On The Impacts Of Climate Change On Building Engineering

The last 20 years have seen the subject of climate change move from a question of science to one of global political, economic, society and technology policy. To the extent that the construction projects have engaged with climate change, its efforts have hitherto been focused on reducing energy use and carbon emissions to mitigate change, research on adaptation to climate change for the construction is still in its initial stage, there are still many problems to be studied in depth. Under this background, this paper carries out the following works:1. Systematic study on the impacts of climate change on the construction engineering (including built environment, construction materials, building structure and properties of concrete structures) from macro- and micro- perspectives are presented. In response to climate change, measures are given from both adaptation and mitigation aspects to provide technical guidelines for construction enginereing achieving adaptability in the context of climate change. At the same time, based on the current research status, this paper points out the needed scientific research work in the future .2. According to China's current conditions, a Climate Change Adaptability Assessment (CCAA) tool is designed and developed for rural buildings. The aim of this system is to assess the vulnerability and adaptability of a building to the effect of climate change, identify the impacts of climate change on an individual building, and provide a simple and easy method for the owner to decide whether to take necessary measures to adapt climate change. This system contains 3 first-level indicators (adaptation and mitigation), 5 second-level indicators (overheating, flooding, torrential rain, wind and GHG emissions), 2 third-level indicators.3. Two rural residential buildings of Shandong province are selected for cases study, demonstrating the application of the proposed method. The aim of the case study is to check the rationality, feasibility and practicality of the assessment tool and examination which one's adaptability is better in the context of future climate change. In the final of the cases study, specific proposals are put forward for two buildings about how to adapt and mitigate future climate change.
