On the final day of the United Nations Framework Convention on Climate Change (UNFCCC) 21st Conference of Parties (COP21) in Paris, the countries of the world reached an agreement to combat climate change and make investment towards a low carbon future. In recent years, the environment issue has been one of the most concerned questions. The over-exploitation of the resources like coal, gas and petroleum caused pollution, raising the temperature and other related problems. People have already made some actions like making studies on electrical driven vehicle and explore more ways to use free resources like wind, solar and tide. As long as people make attention to the urgent problem, we can save our future and correct the improper behaviors we perform to nature. In the following pages, I show my study of solar energy and the idea of combining living style with the technical method together to realize the full-aspect self-sufficiency living in a high rise building.
