Comparative Research on the Low-Carbon Urban Block Morphological Design

Reducing carbon emissions to mitigate global warming is a major problem facing mankind. Since city is the main region of global carbon emission, it is of great significance to promote low-carbon development and build low-carbon city. The urban block scale is the key aspect of the construction of low-carbon city, thus the scientifically compiled urban design guidelines have a kind of quite essential practical guiding value for the construction of low-carbon cities. For this reason, the shortcomings of the methods are summarized in this paper through combing, comparing and analyzing the relevant literature from four aspects of calculation and evaluation of carbon emission in block scale, carbon emission and block shape, optimization design method of low carbon block shape, scientific guidance and control of low carbon block form. Furthermore, the key issues, main problems to be solved and aims of future study are discussed.
