\tClimate-resilient restoration strategies\u00a0<\/p>\n
When it comes to restoring historic buildings, the current guiding principle is to preserve as much of the original structure as possible. To achieve this, the ETH Zurich researchers are studying how exactly the sandstone becomes damaged.\u00a0Water plays a key role in all degradation mechanisms,\u00a0and much of this comes through rain. While vertical rain can be managed by architectural interventions, wind-driven rain cannot. Exposure to such rain, but\u00a0in particular extreme\u00a0events of fast and extreme wetting, followed by rapid drying appears\u00a0to be\u00a0a\u00a0key factor\u00a0in\u00a0degradation and\u00a0is\u00a0very\u00a0location-specific.\u00a0\u00a0<\/p>\n
During such events, moisture penetrates the clay-bearing sandstone used to build the cathedral and causes damage through processes such as swelling, salt crystallisation and freezing. To study how damage occurs and examine the influence of air pollution, the ETH Zurich researchers have been measuring wind-driven rain and the local microclimate, as well as moisture profiles within the stones over a number of years using a network of sensors around the cathedral.<\/p>\n
Alongside this, ETH Zurich researchers are also developing a model to\u00a0correlate local exposure, in particular\u00a0wind-driven rain,\u00a0to the observed forms and extents of\u00a0damage. Experts could use\u00a0this\u00a0as a tool to\u00a0predict\u00a0how damage may change in the future, not just\u00a0as a result of\u00a0the course of time, but in relation to climate changes, in particular the nature,\u00a0intensity\u00a0and frequency of extreme events\u00a0around the cathedral. They could then use this information as a basis to develop tailored restoration strategies and improve the durability of restoration measures,\u00a0anticipating\u00a0the consequences of climate change, which\u00a0represents\u00a0a real challenge\u00a0for practitioners.\u00a0\u00a0<\/p>\n
Applicable to other buildings\u00a0<\/p>\n
The use of digital tools such as 3D models or\u00a0Heritage\u00a0Building Information Modelling\u00a0is nothing new\u00a0in built\u00a0heritage.\u00a0However,\u00a0the \u201cHeritage++\u201d project takes this one step further by integrating information from various disciplines,\u00a0with a focus on conservation,\u00a0allowing it to be used interactively\u00a0and also\u00a0making it possible to include\u00a0conservators\u2019\u00a0practical knowledge\u00a0and\u00a0expertise. In\u00a0the\u00a0future, the digital co-pilot, as applied in Lausanne Cathedral, could also be used for other sandstone monuments, such as bridges,\u00a0castles\u00a0or monasteries, and, in the medium term, for buildings made from other construction materials.\u00a0<\/p>\n
Christophe Amsler, the architect responsible for Lausanne Cathedral, believes that digital technologies will become an integral part of conservation work: \u201cPreserving historic monuments requires constant care and attention. Advances in technology can help us to repair and\u00a0keep\u00a0these buildings\u00a0living, but at the same time, we need to remain faithful to the original spirit and heritage of the monument.\u201d\u00a0<\/p>\n","protected":false},"excerpt":{"rendered":"Climate-resilient restoration strategies\u00a0 When it comes to restoring historic buildings, the current guiding principle is to preserve as…\n","protected":false},"author":2,"featured_media":101691,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":"","_share_on_mastodon":"0"},"categories":[9],"tags":[1208,225,8614,6243,94,1202],"class_list":["post-101690","post","type-post","status-publish","format-standard","has-post-thumbnail","category-lausanne","tag-architecture","tag-artificial-intelligence","tag-computer-and-information-technology","tag-homehero","tag-lausanne","tag-news"],"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@ch\/116901615092058041","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/ch\/wp-json\/wp\/v2\/posts\/101690","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/ch\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/ch\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ch\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ch\/wp-json\/wp\/v2\/comments?post=101690"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/ch\/wp-json\/wp\/v2\/posts\/101690\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ch\/wp-json\/wp\/v2\/media\/101691"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/ch\/wp-json\/wp\/v2\/media?parent=101690"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/ch\/wp-json\/wp\/v2\/categories?post=101690"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/ch\/wp-json\/wp\/v2\/tags?post=101690"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
