The presentation about the gap of building energy saving between China and other countries is illuminated

and the features of embodied energy and building energy intensity are also narrated.Moreover

the introduction is present about the features of subtropical climates

thermal-humidity load and the energy consumption of building materials and construction process.The building total energy consumption involves construction and operation energy

so it can’t be done only to consider building original investment or operation cost.On the contrary

it convicts that it is helpful to building energy saving to minimize energy intensity embodied in building lifetime.
