Evaluating protection against lightning for historical buildings and cultural heritage monuments

Abstract

A review on the lightning risk management and lightning protection of historical buildings and cultural heritage monuments is presented. Cases of lightning-related damages to historical monuments worldwide are presented with emphasis given to cases in Greece. Recorded incidents stress the need for an effective lightning protection system (LPS) design, ensuring sufficient protection of the monument against lightning, including its installations and contents, as well as persons. External LPS of several monuments and historical buildings worldwide are also presented. An external LPS has been designed for the Parthenon monument in Greece in accordance with IEC 62305. The LPS design has been evaluated based on a stochastic lightning attachment model. Revisions to the risk management of IEC 62305 with special focus on historical buildings and cultural heritage monuments are suggested. As this special category of structures is most commonly subject to constraints with respect to aesthetic intervention and construction, dedicated studies employing alternative methods for LPS design, based however on physical grounds, are required.
