Modern society exerts considerable strain on our architectural heritage, partly due to the increase of population and the associated demands on the built environment, and also because of the pernicious effects of pollution. The difficulties and costs of repairs and maintenance contribute to the neglect of important buildings in times of economic stress. It is hence important that our research addresses not only technical questions, but solutions that can be implemented in practice, where social and economic considerations may be paramount. The STREMAH conference fulfils the important function of bringing together experts from different disciplines from all over the world to discuss problems of common interest and put forward solutions. The STREMAH conference over the years has addressed interdisciplinary topics and evolved into a meeting that attracts a wide range of expertise. It has also produced many outstanding contributions published in the conference books distributed throughout the world. Furthermore, papers published since 1993 are available in the WIT eLibrary (http://library.witpress.com), where they constitute a permanent record of the most significant work in the field.
