how core concepts and principles relate to each stage
of a building’s life, each guidance chapter contains
hyperlinks to relevant principles described in Chapter
1 and other related material throughout the text. Each
guidance chapter also includes methods for verifying
the appropriate implementation of the moisture
control recommendations and a reference section
that identifies additional related resources for readers
interested in more detailed information.
