DEHNplan – digital lightning protection planning
With the DEHNplan design software, you can achieve external lightning protection quickly and in compliance with standards. With just one tool, you can easily plan standard-compliant external lightning protection for your project.

What makes DEHNplan stand out
The BIM-enabled software (Building Information Modelling) for engineering offices, planning engineers and lightning protection installers facilitates your planning by visualising the protected volume and separation distances and by providing an automatic bill of materials. Regular software updates ensure performance. You do not need any special prior knowledge to use DEHNplan: Your expertise in lightning protection and earthing, as well as CAD knowledge, are the most important prerequisites for using DEHNplan optimally and efficiently.
DEHNplan conforms to EN 62305.
