Bird-friendly building design
Preface This is the first edition of CSA A460, Bird-friendly building design. CSA A460 covers bird-friendly building design in both new construction and existing buildings. This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group. Scope 1.1 General 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. 1.2 Exclusions 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. 1.3 Terminology 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.
