Defense against damage caused by lightning strikes, lightning protection risk assessment and determining what measures are needed, where and to what extent in a building became important issues nowadays. In 2009, the old lightning protection standard MSZ-274 was replaced by the new standard MSZ EN 62305: 2006.
The risk calculation, being expounded in the second part of the standard, is complex and complicated. The aim of this thesis is to develop a program that supports these calculations. In particular, the program should be able to calculate R1 - risk of loss of human life. In addition, protective measures should also be possible to be set, determining whether the used solution is sufficient or not. The development was governed in a way that facilitates an easier implementation of the other - R2, R3 and R4 - risks calculations in the future.
In the standard I illustrate the program and evaluate the results via the "Hospital" case study. Development and testing have revealed that the risk analysis applied by the existing standard has a number of problems and shortcomings.
In the future this thesis will hopefully be helpful for those students and engineers who work in the field of lightning protection.
