Which calculation should I choose?
- Lightning Risk Assessment
- If you want to see the protection priority for your facility by looking at its lightning exposure, operational consequence and existing protection together.
- Wind & Stability Assessment
- If you are installing a ballasted tripod air terminal system on a roof, or want a preliminary check of an existing system’s stability against wind.
Both tools are indicative preliminary assessments; detailed, standards-based calculation and reporting are carried out by Asiva engineers.
