Local Code Requirement

I am not aware that any code in Vietnam or China has been approved as an equivalent standard.

I am not aware of any code outside the US that has gone through the equivalency process except for the three countries that have their own version of LEED (Canada, Italy, and India). Demonstrating equivalency is a rather involved process. It is described below from the Global ACPs for LEED document. The following process is used to determine the equivalency of a local standard to ANSI/ASHRAE/IESNA Standard 90.1–2007. 1. A group interested in determining equivalency of a particular standard should email a request to USGBC through commonlanguage@usgbc.org. 2. USGBC will collaborate with the group to establish a method for creating an equivalency study and a timeline for completion. 3. The group will conduct the study. 4. USGBC will review the study and bring its recommendation to the LEED International Roundtable with approval by the LEED Steering Committee. 5. Typically, the group putting forward the standard will cover the cost of the study and USGBC review. 6. Priority of USGBC review will be determined based on market transformation potential and representation of the country on the LEED International Roundtable. 7. Approval of equivalency will be determined by the LEED Steering Committee and communicated to the group. 8. Upon approval by the LEED Steering Committee, the equivalency will be made available to projects through a USGBC-administered LEED Interpretation.
