Summary
This study aims to understand the views and experiences of Tampere residents in Finland about multi-story timber-framed apartments and wooden structures through a questionnaire. The 151 responses highlighted two main issues: (1) multi-story timber-framed apartments were rated as a good product in terms of user satisfaction, which was based on the following findings: (1a) for most of the respondents, the apartment had fresh air and a suitable temperature on cold winter days; (1b) the majority felt safe living in a multi-story timber-framed apartment; (1c) respondents generally were satisfied with the soundproofing, except for the disturbing noises from the upper floor and the stairwells; (1d) residents’ opinions were mainly positive regarding most of the functional features such as storage facilities, the location and access roads of the building, exterior facade, and wood visibility level; (2) there exists a demand for multi-story timber-framed residential buildings in the market, especially in the customer segment, which is defined as ‘environmentalist’. This was based on the following findings: (2a) living in an environmentally friendly, low-carbon, natural-material apartment, cozier living in a timber-framed apartment, and meaningful use of wood in interiors were notably more important for the extremely satisfied residents; (2b) building facades, and floors and ceilings inside the apartment were the places where the use of wood was most desired in the apartment. This article is intended to be a guide for key construction experts, e.g., architectural designers and developers to better understand and meet the demands and needs of timber-framed apartment residents in Finland.

Summary
As a result of increasing urbanization, the need for sustainable housing, e.g., tall (over eight-story) timber apartments, is increasing in Finland. Leveraging the experience of key Finnish professionals plays a significant role in the transition and expansion of sustainable timber housing as an essential part of the forest-based bioeconomy. This interview-based study will serve to fill a gap by examining the views of key professionals with experience in tall timber residential construction, using Finland as a case study. The 21 interviews primarily highlighted that: (1) the construction cost was the most important parameter affecting the architectural and structural design; (2) the most critical consideration influencing the overall design was reported to be the structural system selection and structural design, followed by city planning and client control; (3) key professionals assessed the building’s form and the main dimensions of the building’s mass as the most significant parameters affected by timber construction; (4) the main structural considerations that needed to be developed for tall timber housing were the bracing solutions and fittings, the structures of the intermediate floors, and load-bearing vertical/partition structures; (5) construction preconceptions, the lack of cost-competitiveness, and the lack of construction expertise/actors were considered to be major obstacles; (6) the most important parameters for the future of tall timber apartment buildings were reported to be education, timber construction marketing and public awareness, land delivery conditions, the unification of public administration, and financial support; (7) tall timber building design was reported to be a complex subject that requires close collaboration, especially between the architect, the structural designer and the wood supplier. This paper will help us to understand the boundary conditions affecting the design, the development needs in solutions, the importance of design parameters, the design parameters affected by timber construction, and the prospects, measures and obstacles to tall timber apartments from the perspectives of key Finnish professionals, thereby aiding the sound planning and development of tall timber housing projects.

Summary
Adhesives and metal fasteners play important roles in the composition and connections of engineered wood products (EWPs) such as cross-laminated timber and glue-laminated timber in the building construction industry. However, due to their petroleum-based nature, adhesives can cause toxic gas emissions, while metal fasteners compromise the end-of-life disposal and reusability of EWPs. These issues adversely affect the sustainable material properties of EWPs. Numerous studies have been conducted in the literature on the technological, ecological, social, and economic aspects of EWPs in construction with different construction solutions, but no studies have been conducted to evaluate the technical performance of dovetail wood board elements (DWBE) in multi-story or tall building construction. This study focuses on adhesive- and metal fastener-free DWBE as sustainable material alternatives for ecologically sensitive engineering solutions. Various preliminary design proposals are presented for DWBE using architectural modeling programs as an environmentally friendly approach intended for use in the timber construction industry. The research findings are based on a theoretical approach that has not yet been practically tested but is proposed considering existing construction practices that need further investigation, including technical performance tests. It is believed that this paper will contribute to the promotion and diffusion of DWBE for more diverse and innovative architectural and structural applications, particularly in multi-story timber building construction, as one of the key tools in tackling climate change challenges.
