Lightning storms pose a great threat to buildings. Prevention is one of the highest priorities and nowadays it is mandatory for a building to have lightning protection if they are exposed to such forces. Protecting our cultural heritage is key to preserving our past. In my diploma work I give an overview about the steps of designing lightning protection for monuments described by the 2006 European Union lightning protection standard which was introduced as MSZ EN 62305 in Hungary. There are still many questions and interpretation problems surrounding the new standard, because professionals had been using the Hungarian MSZ 274 standard for centuries. Apart from getting an efficient lightning protection, it is also very important for the monument to retain its cultural value by not having an oversized protection. I demonstrated how to perform the necessary risk analysis, which is the longest part of the design. I collected the lightning protection measures that we can use on the score of the risk analysis and how to design it.
In the second part of the diploma work I will explain the design process of the lightning protection of a specific building. My choice fell on the town hall of Baja, which was built in 1745 in Baroque style by the order of the Archbishop of Kalocsa. I performed the necessary risk analysis and then I designed the external and internal lightning protection system step-by-step. I also used the existing metal parts of the building for the external lightning protection system. During the design of the lightning protection I had to consider the aesthetics of the building while also creating an adequate level of protection.
