“…For the use of wood as a building material in multistory residential construction, precise knowledge of the material properties and the structural-physical behavior is necessary [27]. With regard to thermal insulation and moisture performance as well as energy aspects, timber constructions can be comparable to reinforced concrete constructions [3]. In addition to the acoustic improvement of constructions, the ecological effects should also be considered when considering the development and planning goals.…”

“…As a result, the use of natural and renewable materials, such as wood, has been increasing in the recent decade. This raw material has been used as a building material in traditional construction for centuries and its material properties as well as its building physics characteristics provide it with good prerequisites as a material for innovative and sustainable construction solutions [3]. Due to the increasing awareness of sustainability and resource conservation, it is therefore gaining importance in contemporary architecture [4].…”

Due to the high consumption of resources and energy in the construction sector, the development of resource-efficient and sustainable construction solutions is gaining increasing attention. The awareness of sustainability and resource conservation results in the interest of using natural and renewable materials in contemporary architecture. Timber construction methods offer both constructive and ecological potential for sustainable solutions. From a building physics perspective, the acoustic performance of lightweight buildings, such as those made of timber, presents a challenge. Even if standard requirements are met, the increased low-frequency sound transmission typical for light-weight construction can cause discomfort and is already the subject of questions in building physics, which are currently increasingly extending to timber construction. Within the framework of a holistic approach, this paper compares the problem of acoustic properties, design optimizations and the ecological properties of timber-frame and solid timber construction components. The comparison with heavy materials, such as concrete, shows the relation of acoustic optimization with the change of the environmental profile. In order to establish the interaction between acoustic quality of wooden ceiling constructions and their ecological characteristics, this article aims to demonstrate the potential of materials used in the building sector under ecological aspects considering a life cycle analysis.

“…These differences are mainly caused by the thermal mass of the load-bearing materials and the thickness and properties of the thermal insulation. In Müller et al [16], the different energy demands for cooling and heating of timber and RC structures are modelled using WUFI software based on a one-room model. The results show that the cooling energy demand is higher for both timber frame and mass timber construction compared to precast concrete, while the heating energy demand is slightly lower.…”

With the introduction of energy-efficient buildings, the importance of embodied energy in new buildings has become increasingly relevant to minimising the impact of climate change. This study compares two existing four-storey residential buildings: one building has a reinforced concrete (RC) structure and the other has a timber structure. The study’s aim is to find out which building components are responsible for the largest embodied impacts and whether there are differences between the two construction methods. The specificity of the wooden building is the combined use of solid and lightweight timber elements. The methodology consists of a general life cycle assessment (LCA) and a more detailed analysis of the product stage using the eco2soft software. The heating and cooling energy demand was calculated using the WUFI Plus software with recent regional climate data sets. The results show that for both types of construction in multi-storey buildings, it is not only the superstructure that needs to be considered, but also the floor structures, which have a major influence on the embodied impact. The timber building requires less energy to maintain the indoor climate within the set temperatures. As climate change has progressed rapidly in Austria in recent years, it is recommended that the standards for climate models be updated more quickly to allow realistic prediction of thermal comfort at the design stage.

“…Nowadays, much attention is paid to resource-saving and environmentally friendly materials that have a minimal environmental impact. Whole-section timber meets these requirements in full (Müller et al, 2021;Skullestad et al, 2016). According to the results of studies on wood materials, solid wood has the least impact on the human habitat (Cabral and Blanchet, 2021;Dias et al, 2020).…”

Introduction: In recent years, houses out of vertical squared timber have become widespread. Vertical bars make it possible to use the effective wood behavior in compression and ensure maximum strength of the material along the fibers. Vertical bars are subject to compression with bending, which can result in loss of strength and buckling in building structures. In the available research papers and technical literature, the issue of the stress-strain state of such walls has not been analyzed. The purpose of this study was to formulate a calculation method for walls out of vertical squared timber, based on the available traditional approaches to wooden structures. We propose a calculation method for walls out of vertical squared timber as a set of elements resisting compression with bending, including a check for limiting slenderness. Results: Permissible heights of walls for buildings with bays of 10 and 12 m were obtained. The results can be used in the design of low-rise residential and public buildings, mansard superstructures of multi-story buildings.
