Notes/comments

This acceptable solution is the second edition of G7/AS1. The main changes from the previous version of
G7/AS1 are:

  • The scope of G7/AS1 has been reduced to cover only simple buildings up to 3 storeys in low density developments. Requirements applicable for simple and complex high rise buildings and apartments are available in Acceptable Solution G7/AS2 and Verification Method G7/VM1. To reflect the new scope of the documents and the new document layout, a new introduction and scope has been provided in Part 1. General.
  • The scope of G7/AS1 has been reduced and is no longer applicable for awareness of the outside through another space. The applicable requirements can be found in Verification Method G7/VM1.
  • Portions of text have been re-written to enhance clarity in the document and provide consistent language with other acceptable solutions and verification methods.
  • The definitions page has been revised to include all defined terms used in this document in Appendix B.
