Abstract
The growing diffusion of cross-laminated timber structures (CLT) has been accompanied by extensive research on the peculiar characteristics of this construction system, mainly concerning its economic and environmental benefits, lifecycle, structural design, resistance to seismic actions, fire protection, and energy efficiency. Nevertheless, some aspects have not yet been fully analysed. These include both the knowledge of noise protection that CLT systems are able to offer in relation to the possible applications and combinations of building elements, and the definition of calculation methods necessary to support the acoustic design. This review focuses on the main acoustic features of CLT systems and investigate on the results of the most relevant research aimed to provide key information on the application of acoustic modelling in CLT buildings. The vibro-acoustic behaviour of the basic component of this system and their interaction through the joints has been addressed, as well as the possible ways to manage acoustic information for calculation accuracy improvement by calibration with data from on-site measurements during the construction phase. This study further suggests the opportunity to improve measurement standards with specific reference curves for the bare CLT building elements, in order to compare different acoustic linings and assemblies on the same base. In addition, this study allows to identify some topics in the literature that are not yet fully clarified, providing some insights on possible future developments in research and for the optimization of these products.
Highlights
Cross-laminated timber (CLT) is an engineered timber product at the basis of an articulated construction system that is rapidly establishing itself for the construction of wooden buildings designed to achieve particular structural performance, allowing the rationalization of site management and reduction of construction time [1,2,3].Among the wooden construction systems, cross-laminated timber structures (CLT) represents one of the most interesting and innovative material
This systematic review of the acoustic characteristics of cross-laminated timber systems was not limited to an analysis exclusively based on the evaluation of the progression of knowledge on this topic, and tried to frame the problem of noise protection in the broader context of the definition of the main aspects necessary for an overall characterization of a relatively new building product
It has highlighted that the acoustic aspects have been the subject of interest in a systematic way only after 20 years of use of this construction system
Summary
Cross-laminated timber (CLT) is an engineered timber product at the basis of an articulated construction system that is rapidly establishing itself for the construction of wooden buildings designed to achieve particular structural performance, allowing the rationalization of site management and reduction of construction time [1,2,3].Among the wooden construction systems, CLT represents one of the most interesting and innovative material. The reduction of energy consumption is currently one of the main priorities at international level and the building industry represents one of the sectors that can make an important contribution to saving energy and achieving the objectives of energy efficiency [6,7,8,9]. Taking into account these evaluations, the European Union is moving the construction market in a more ecological direction with the aim of achieving a 20% reduction in global energy consumption by 2020; many designers are taking into consideration new sustainable technological solutions [10]
