“…On the other hand, among architects uncertainties related to compatibility issues concerning building codes have hindered, for example, usage of cross-laminated timber (CLT) (Laguarda Mallo and Espinoza 2014). Connected to building solutions, for example choice of technologies has been found to affect acoustics and insulation properties of CLT structures (Van Damme et al 2017).…”

Multi-storey wood building (MSWB) provides options to enhance sustainable development. Despite this, no comprehension exists on how consumer perceptions differ regarding (1) willingness to live in modern houses made of timber or (2) prejudices against living in houses made of wood, although they play important role in marked demand of MSWB. In this research, views of consumers on the benefits of wood from technological, ecological, social and economic perspectives are being studied. The material of the study is based on data gathered in June-July 2018 by a postal survey sent for 1000 people living in Finland with a response rate of 25.6%. According to the factor analysis results, there are two main consumer categories based on their perceptions on sustainability benefits of wood, i.e. the ones favouring ecological and physiotechnological benefits of wood and the ones favouring aesthetic and well-being benefits of wood. Additionally, according to binary regression analysis results, they differ from each other in their willingness to live in wooden houses and in their prejudices against the appropriateness of wood as a structural material. The results emphasize the need for deepening the understanding of the sustainability issues affecting the acceptability of wood among different types of consumers.

“…The other characteristic, important for the serviceability of these structures, is its dynamic behaviour and it has been extensively studied in the literature (Damme et al 2017, Casagrande et al 2018, Kozaric et al 2019, Huang et al 2020). The CLT system can be used for single unit housing and multi-storey buildings.…”

The beginning of the new millennium brought a revolution in the application of timber as a material for the construction of multi-storey buildings for various purposes. The CLT is a European innovative timberbased material in which timber boards, made of home-grown timber species (mainly Spruce) are assembled in layers and glued together crosswise in order to form massive timber wall and floor panels. The crosslamination method gives a material with high stability, good mechanical properties, good thermal insulation and a good behaviour in case of earthquake or fire Cross laminated timber (CLT) is an innovative timber-based product that enables the structural design of multi-storey and high-rise buildings with a number of advantages, of which its seismic behavior stands out. This paper presents the basics of seismic analysis of multi-storey buildings made of cross-laminated timber construction, the way of forming connections of structural elements in accordance with the appropriate seismic load and an overview of specific parameters that are part of the calculation, based on certain experimental observations and state of the art of codes and research in this field.

“…Additionally, CLT is mainly structural but can also be used as a facade material and a secondary building material, e.g., floor and non-structural walls [ 19 ]. In the literature, many studies focus on the technological aspects of EWPs, their use in construction, and different building solutions [ 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 ]. Several studies address wood as a structural material in buildings from the perspectives of key professionals (e.g., [ 51 , 52 , 53 , 54 , 55 , 56 , 57 , 58 , 59 ]) and consumers or residents (e.g., [ 60 , 61 , 62 , 63 , 64 , 65 ]).…”

To date, in the literature, there has been no study on the comparison of hybrid (timber and concrete) buildings with counterparts made of timber and concrete as the most common construction materials, in terms of the life cycle assessment (LCA) and the carbon footprint. This paper examines the environmental impacts of a five-story hybrid apartment building compared to timber and reinforced concrete counterparts in whole-building life-cycle assessment using the software tool, One Click LCA, for the estimation of environmental impacts from building materials of assemblies, construction, and building end-of-life treatment of 50 years in Finland. Following EN 15978, stages of product and construction (A1–A5), use (B1–B6), end-of-life (C1–C4), and beyond the building life cycle (D) were assessed. The main findings highlighted are as following: (1) for A1–A3, the timber apartment had the smallest carbon footprint (28% less than the hybrid apartment); (2) in A4, the timber apartment had a much smaller carbon footprint (55% less than the hybrid apartment), and the hybrid apartment had a smaller carbon footprint (19%) than the concrete apartment; (3) for B1–B5, the carbon footprint of the timber apartment was larger (>20%); (4) in C1–C4, the carbon footprint of the concrete apartment had the lowest emissions (35,061 kg CO2-e), and the timber apartment had the highest (44,627 kg CO2-e), but in D, timber became the most advantageous material; (5) the share of life-cycle emissions from building services was very significant. Considering the environmental performance of hybrid construction as well as its other advantages over timber, wood-based hybrid solutions can lead to more rational use of wood, encouraging the development of more efficient buildings. In the long run, this will result in a higher proportion of wood in buildings, which will be beneficial for living conditions, the environment, and the society in general.
