national supplements containing additional information
on risk management for example, Supplement 2
(Calculation aids for estimating the risk damage for
structures), which offers assistance with the often
complicated process assessing the risk damage.
The local risk determined multiplying the fre-

The building’s required risk level determined the
basis the risk lightning strike and the damage
