, Design of Exterior Shading Devices, was developed to offer design considerations for manufacturers, architects and other members of the design team, as well as present important information for those responsible for facilities maintenance.

“Exterior shading devices are often incorporated into the façade of commercial and institutional buildings to reduce solar heat gain and to add elements of visual interest,” said Steve Fronek (), Chair of the AAMA APG Shading Device Task Group. “This technical information report presents design considerations for manufacturers, architects and other members of the design team, as well as information for those responsible for facilities maintenance.”

This document should be used in conjunction with , Standard Test Method for Static Loading and Impact on Exterior Shading Devices, in preparation of architectural drawings and specifications, shop drawings and structural calculations, and maintenance programs, to avoid some of the technical and practical issues that can arise from improper design or application of shading devices.

Items in the scope of this document include, but are not limited to, impact loading on exterior shading devices, combined loading, new construction/renovation, window washing considerations, thermal bridging, glazing and more. Items not within its scope include interior light shelves, window wells and other considerations.
