Abstract
This study analysed climate change effects concerning the resilience of timber buildings located in southern Chile, specifically in two cities: Collipulli and Temuco (Araucanía Region). A digital fuzzy logic method was used in a set of timber buildings declared as heritage conservation buildings by Chilean Government standards. The outcomes revealed that climate change impacts did not substantially alter the functional performance of the set of heritage timber buildings examined. This study’s results can assist in developing upcoming strategies or recommendations that can support adaptation policies for administering architectural heritage regarding climate change forecasts. These data will invaluably help stakeholders who support the conservation of timber structures located in the southern environment of Chile and under the changing climatic hazard.
Highlights
Heritage buildings and infrastructures are one of the most visible parts of a society and even of a region’s history, showing several forms of cultural values expressed over time [1]
The three subsections discuss the applicability of the fuzzy logic model to the set of case studies examined in the Araucanía Region: (i) application regarding current climate conditions; (ii) application considering two climatic situations (RCP2.6 and RCP8.5) of climate change predictions for a near future period (2020–2044); (iii) application of the fuzzy logic system to the sample concerning two specific climatic situations (RCP2.6 and RCP8.5) for a distant future period (2045–2069)
The functional performance method (FBSL2.0) was applied to a total of seven timber buildings located in southern Chile: four in the capital region of Temuco and three in the city of Collipulli
Summary
Heritage buildings and infrastructures are one of the most visible parts of a society and even of a region’s history, showing several forms of cultural values expressed over time [1]. Institutions, authorities and stakeholders have accepted the inevitable requirement to maintain their socio-cultural resources [9] This is paramount because the renovation of urban heritage city centres offers several benefits related to several variables associated with regenerating neighbourhoods [10], which could be more appropriate for possible new external investments. The urban heritage city centre is mainly constituted of public spaces, called historical zone conservations (HZCs), and buildings, called historical building conservations (HBCs), which, due to the fact of their historical features, are defined as examples of collective memory conveyed from generation to generation These urban and architectural locations reflect several cultural features that define the community backgrounds of the municipality and even the territory in which they are placed [11]. New research must be developed to assess and understand climate change effects on the architecture, construction and engineering sectors, for heritage buildings, to achieve new advances to be adopted in future practices
