Creating a feature for the involves digitizing the parameters found in IEC 62305-2 Annex J . This tool was originally designed to assess lightning risks for simple, single-zone structures without requiring the exhaustive calculations of the full standard. ⚡ Core Functionalities of SIRAC
Another comparative study looked at SiRAC versus the full standard method when applied to a heritage building in La Plata, Argentina. The paper noted that SiRAC allowed for more than one service line (power, telecom), which was useful, but it ignored the influence of adjacent structures—a factor that could be critical in dense urban environments.

To calculate these figures, a tool like SIRAC or its modern equivalents takes four specific categories of inputs: 1. Structural Dimensions simplified iec risk assessment calculator sirac

A free online tool and mobile app specifically designed to simplify the IS/IEC 62305-2 calculations .
By condensing multi-layered algebraic equations into a user-friendly interface, SIRAC allows engineers, architects, and safety officers to input basic structural data and quickly determine whether a building requires a Lightning Protection System (LPS). The Core Methodology: IEC 62305-2 Compliance Creating a feature for the involves digitizing the
Automatically computes the collection area for the structure and its connected lines.

This was where Henderson usually tuned out, but Elias knew it was the heart of the matter.
