Wind certification, also referred to as wind compliance, is a product approval in which equipment for buildings are evaluated for their ability to withstand the effects of wind and windborne debris.

The goals of wind certification are to ensure that:

  • Equipment for buildings remains in place (anchorage stays intact)
  • Pieces or portions of equipment do not detach and pose a threat to life-safety or other equipment
  • Essential facilities (hospitals, police and fire stations, emergency shelters, military installations, data centers, nuclear facilities, etc.) are able to function and provide critical services following a wind event.

Wind certification or analysis for wind loading is required for most buildings, and it is not limited to just essential facilities. Consideration of wind effects is an essential part of building design.


Wind certification is a systematic analysis of equipment for wind loading. Each part of the product needs to be evaluated including the Main Wind-Force Resisting System (MWFRS), components and cladding, and anchorage. Components and cladding receive the wind forces, while the MWFRS transfers the wind forces through the component and down to the supporting structure through the anchorage. A complete load path needs to be maintained throughout the equipment, down to the supporting structure.

A well-developed wind certification program requires detailed consideration of the equipment under consideration. In order to properly develop a program, certain key elements must be considered, including: materials of construction, externally mounted sub-components, product options, mounting details, connected elements and details of construction. These items must be accounted for in the certification and appropriately documented so users understand certification limitations and ensure a valid wind certification for a given installation.
