Enter your project data to generate a preliminary lightning-protection design and quantity estimate based on applicable IEC / IS / NBC design criteria. Review the IEC 62305-2 risk-input requirements, compare Rolling Sphere, Mesh and Protective Angle methods, and prepare an indicative BOQ for budgeting, tendering and initial project planning.

Enter the project geometry and roof conditions first. The visual model and preliminary method view use the selected design criteria. Final design criteria remain subject to the IEC 62305-2 risk assessment, complete project information and engineering review.
The risk-management step comes before finalizing the protection measures and LPS design. Building geometry/use are taken from the project inputs; complete the remaining risk information here. Until the required inputs are reviewed, the website shows a preliminary design estimate only.
Enter the missing details in this section. After submission the project status changes to Ready for SN Engineering Risk Review.
Use the same building to compare Rolling Sphere, Mesh and Protective Angle arrangements. The visual, preliminary quantities and explanations change together. Applicability depends on the structure geometry, selected LPS class and the applicable IEC / IS / NBC design criteria.
Whole-building strike-point and protected-volume evaluation.
Roof conductor network using the selected LPS mesh reference. Mesh intersections are not automatic rod locations.
Local air-terminal protection where geometry and applicable height limits permit.
| Comparison | Rolling Sphere | Mesh | Protective Angle |
|---|---|---|---|
| Primary design concept | Checks exposed strike points around 3D geometry | Roof conductor network | Protective zone around an air terminal |
| Complex roof / HVAC / PV | Strong fit | May need additional rods / detailed checks | Local use only where applicable |
| Simple flat roof | Applicable | Strong fit where mesh arrangement is selected | Can be suitable for local points |
| Vertical rods | Placed only where protected-volume design requires | Not automatically at mesh intersections | Method depends on selected rod geometry |
| Customer visibility | Very clear 3D protection concept | Very clear conductor layout | Easy for simple local geometry |
| Main limitation | Needs actual 3D geometry | Does not by itself solve all protrusion/clearance issues | Not suitable as a universal whole-building shortcut |
Even if no drawing is uploaded, the system provides preliminary planning quantities from the entered dimensions, building use, rooftop condition, selected LPS class and stated calculation assumptions. These quantities are for budgeting, tender preparation and initial project planning only.
