Description / Abstract:


This Standard covers bird-friendly building design in both new construction and existing buildings and is intended to reduce bird collisions with buildings. The Standard provides bird-friendly design requirements for glazing, building-integrated structures, and overall building and site design.


This Standard considers design aspects of glazing, buildings, and sites only from the point of view of bird strikes. Other standards and codes make recommendations regarding building characteristics that are not addressed in this Standard (e.g., energy efficiency, building occupant comfort, glazing safety).

Certification procedures are not part of this Standard.


In this Standard, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the Standard; “should” is used to express a recommendation or that which is advised but not required; and “may” is used to express an option or that which is permissible within the limits of the Standard.

Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.

Notes to tables and figures are considered part of the table or figure and may be written as requirements.

Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
