However, natural environmental damage brought by us is also accelerating. Natural disasters happen frequently, including ecological degradation and deterioration, energy resources crisis, greenhouse effect, earthquakes, tsunamis, volcanoes etc. The global crisis has once again waken-up call to mankind. How to properly solve these crises had become a common and urgent responsibility of mankind. This paper will mainly discuss and seek some new potential methods in solving energy crisis and environmental problems from the perspective of automotive and architecture design. As an architect, how to avoid light pollution and reduce heat absorption of roof, increasing heat reflectance of roof are becoming their main and urgent responsibilities. On the other hand, reducing greenhouse effect, researching and developing new low-carbon, low-emission fuel sources are also becoming automotive designers＇ obligations. Living in harmony with nature ＆ earth is becoming the common human themes of the 21 st century.展开更多
