The May/June 2009 issue of "Facilities Manager" introduced APPA readers to the Whole Building Design Guide (WBDG)--today's most comprehensive Internet-based depository of resources contributing to a systems approach for everything of a building nature. The emphasis in that article was on Operations and Maintenance (O&M) issues and procedures. In this article, the author applies WBDG's "Design Guidance Model" (a complement to O&M issues) to address safety and security design needs in the open spaces surrounding and contiguous to education, commercial, and industrial buildings. There are four sections for the author's discussion: (1) WBDG's Design Guidance; (2) WBDG's Design Objectives; (3) WBDG's Design Disciplines; and (4) Safety, Security, and System Dynamics. (Contains 13 notes.)
