“…Reliable models of the degradation of stone claddings along the service life are required for the optimization of the maintenance and service life expenses of the external stone cladding [37]. A key factor in maintaining the durability and service life of the stone claddings is the external claddings' maintainability [38]. Recent models have made it possible to forecast the service life and maintenance of exterior stone cladding facades by introducing the condition-based, functional, and physical performance of natural stone claddings [39,40].…”

The attractiveness and durability of stone claddings make them a common exterior finish. However, comparative research of the performance of long-lasting “dry fixed” stone claddings and those made using the “wet fixed” method has not yet been carried out. The objectives of this study are to (1) characterize the deterioration patterns of exterior dry- and wet-fixed stone claddings exposed to normal and marine environments; (2) evaluate the life expectancy limiting coefficient (modifying factors), and (3) quantify the influence of a marine environment on both cladding methods. The research methods integrate laboratory tests with the field survey and probabilistic service life prediction methods. The results of laboratory tests indicate that the compliance of the stone with the requirements of the standard does not assure the durability of the stone when used as an exterior cladding material in a marine environment. The findings of the probabilistic methods show that, in both normal and marine environment service conditions, the fixing method has a significant impact on the rate of the stone deterioration process and the long-term durability of dry-fixed stone claddings.

“…Urbanization has not only sprawled horizontally, where lands are cleared and buildings are erected, but also vertically, where we continue to build taller and taller buildings, especially in land-scarce cities [3,4]. With the unprecedented rate of urbanization, the field of building maintenance and management has been growing in both research and applications [5][6][7]. One of the major areas in building maintenance and management is building inspection for defects and fault detection.…”

Climate Change Projection and Its Impacts on Building Façades in Singapore

Singapore is one of the most populous countries, and the majority of the population stays in high-rise public flats. In 2021, there were about 1.1 million public residential units, of which 79% were above 20 years old. The number of incidents of falling objects from a height has been increasing due to the aging and deterioration of buildings. The Periodic Façade Inspection (PFI) regime was enacted in 2020 to mandate façade inspections for all buildings above 13 m and exceeding 20 years old. However, the relatively new PFI regime has not considered the potential impacts of climate change on building façades. In this paper, the common root causes of façade defects that can be impacted by climate change are first identified. Based on the climate projection in Singapore to 2100, Singapore is expected to experience a higher mean temperature, a higher rainfall intensity, more extreme rainfall events, and a higher wind gust speed. Overall, these changes in the climate pattern will accelerate corrosion or degradation, material fatigue, adhesion failure, biological attack, and humidity or dampness. The impacts of climate change on vertical greeneries are also discussed. This paper provides a first insight into the key concerns to focus on for the future revision and improvement of the PFI regime to incorporate climate change impacts on façades.
