Documentation Flexibility 文档灵活性

LEED v5 allows more flexible documentation compared to previous versions. Projects may use online software tools to generate compliance documentation, reducing administrative burden.

与先前版本相比，LEED v5 允许更灵活的文档记录。项目可使用在线软件工具生成合规文档，减少行政负担。

Strategy for Max Points 满分策略

Specify low-VOC products early in the specifications to ensure 90%+ compliance.
在规范中尽早指定低 VOC 产品，确保 90%+ 合规率。
Require submittals from contractors confirming VOC-compliant product installation.
要求承包商提交确认文件，证明安装了符合 VOC 要求的产品。
Track by surface area (especially for flooring, wall, ceiling) to simplify calculations.
按表面积追踪（特别是地板、墙面、吊顶），以简化计算。
