ABSTRACT: Under the Kyoto Protocol,Japanwas supposed to reduce six
percent of the green house gas (GHG) emission in 2012. However, until the year 2010, the statistics
suggested that the GHG emission increased 4.2%. What is more challenge is,
afterFukushimacrisis, without the nuclear
energy,Japanmay produce about 15 percent more GHG emissions than1990 inthis fiscal year. It still has to struggle to
meet the target set by Kyoto Protocol. The demonstration area of “smart
community” suggests Japanese exploration for new low carbon strategies. The
study proposed a demand side response energy system, a dynamic tree-like
hierarchical model for smart community. The model not only conveyed the concept
of smart grid, but also built up a smart heat energy supply chain by offline
heat transport system. Further, this model promoted a collaborative energy
utilization mode between the industrial sector and the civil sector. In
addition, the research chose the smart community inKitakyushuas case study and executed the
model. The simulation and the analysis of the model not only evaluate the
environmental effect of different technologies but also suggest that the smart
community inJapanhas the potential but not easy to achieve the target, cut down 50% of the CO2 emission.
