The core values of low carbon sustainable residential development are energy conservation and emissions reduction, promoting the transformation from modern architecture to green sustainable architecture.
Although our country's emissions of carbon can not reach the emissions standards of the developed countries in the short term, but also our country should put forward the important index with the possibility to implement data range.

Other data can be gained from reference [5] .
The attenuation process can be divided into three stages, firstly, before bar corrosion, reliability index β keeps basically the same; Secondly, after bar corrosion, reliability index β begins to drop, it is a modest reduction; Thirdly, after corrosive crack appears in the concrete protective layer, reliability index β drastically pruned.

These data were used to defy the range of temperature for XRD investigation between 500 and 900 °C for the as-spun PVP/KNNL composite nanofibers.
The reduction in size of the nanofibers could be attributed to the decompositionof PVP from the nanofibers and the crystallization of KNNL.

That means that, the driving force for grain growth is a reduction in the energy which is stored in the material in the form of grain boundaries.
The n values at different temperatures are obtained by fitting the experimental grain size data using Equation (1) and the calculated n values are given in Table 1.
