To help you learn and use standard, I am here to interpret their own understanding of the content of what standard, something wrong, please correct me criticism.
Code contains common principles, terminology, calculation of the three chapters of the provisions of the construction area and as the Regulation of directions. Are explained together.
The first part of the general principles expounded
normative intention, range, construction area of ​​principles to be emulated. The second part cites 25 term, the provisions of the gross floor area of ​​buildings involved in the relevant parts of an explanation or definition of the term. The third part of the calculation of the provisions of a total construction area of ​​25, including the building area calculation,Gucci Shoes 2010, calculation usages and the scope of the construction area does not count. Provisions that regulate the provisions of the construction area of ​​the specific contents, usages to do the careful definition and description, in order to accurately use the rules and methods. Here to talk approximately the specifications focus on the calculation of floor area requirements.
First, housing construction in the cardinal part of
