ABSTRACT
Be lean, be green and be clean are the mainstream thoughts in sustainable building design. However, lacking of regional and empirical design data and references impedes architect and engineer’s bold endeavour in the real project. This article studies various tall building low carbon and low energy strategies in the selected Chinese cities like Beijing and Shenzhen within their representing climate zones. Computer based dynamic thermal simulation is used to understand building envelope, building system, and renewable energy’s impact on tall building energy consumption and operational carbon footprint. Based on IPCC’s Climate Change 2007: Mitigation, mature technologies are the key carbon mitigation and energy saving measures in the coming years till 2020. So, their performances are assessed and rated by international green building standard like LEED. Advanced and renewable technologies subsequently are investigated to minimize building operational carbon footprint further as well as to achieve higher energy saving.
Keywords: Carbon footprint, Dynamic thermal simulation, LEED, Renewable energy, Tall building.
