: A definitive "Yes/No" statement on whether a protection system is mandatory. : Recommendations for Class I, II, III, or IV protection based on the required efficiency. Surge Protection (SPD)

Pinpoints exact vulnerabilities, such as whether a building specifically requires internal surge protection (SPD) rather than external grounding mesh.

SIRAC outputs usually generate clean, comprehensive PDF reports that satisfy local regulatory inspectors and insurance auditors. Who Benefits Most from SIRAC?

Manually calculating lightning risk involves balancing dozens of interconnected formulas, probability factors ( ), and loss factors (

Instead of requiring users to manually compute dozens of interconnected formulas, equations, and probability factors, SIRAC allows users to input specific parameters about a structure. The calculator then instantly processes the data to determine whether lightning protection measures are mandatory, and if so, what Level of Protection (LPL I to LPL IV) is required. The Core Methodology: IEC 62305-2 Risk Types

Offers the basic level of protection (84% efficiency) suitable for simple commercial structures with low internal hazards.

Instead of forcing engineers to calculate collection areas, probability factors, and loss values by hand, SIRAC uses a guided interface to process baseline data. It evaluates the specific risks associated with a structure and outputs a clear verdict on whether a Lightning Protection System (LPS) or Surge Protection Devices (SPDs) are legally or practically required. The Core Methodology: IEC 62305-2 Risks Evaluated The calculator then instantly processes the data to

It is primarily applicable to single-zone structures , meaning it doesn't easily account for complex buildings with vastly different internal sections.
