Utomhuskonstruktioner i trä : några erfarenheter från byggnation i trä av flerbostadshus
- 2017

Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Användandet av materialet trä i produkter är ett lån från naturen som förr eller senare genom nedbrytning av vedsubstansen ska återföras till det naturliga kretsloppet. Avseende användningen av solitt trä i produkter bestäms tidsperioden innan återföringen till naturen av produktens konstruktion och trämaterialet i sig självt i relation till den omgivande miljön samt användningen och hanteringen av produkten. En produkts förmåga att motstå, eller behålla sina egenskaper trots dessa yttre påfrestningar benämns dess beständighet.

Konferensbidrag (refereegranskat)abstract
- The industrialization of wooden house building processes from traditional on-site production to off-site prefabrication is challenging, concerning the possibility of effective handling of numerous product variants, where each house is more or less unique. To obtain high productivity in the production, a well-balanced flow with minimization of waste is of great importance. In Sweden, many off-site house producers are in the starting phases of introducing advanced automation technologies in their production processes and the need for a more detailed process control therefore increases. In previous studies, the installation of windows has been identified as a demanding step in the prefabrication process, since it often creates a bottleneck i.e. the most overloaded part of process (Slack et al., 2016) and thus negatively affects the cycle-time and a balanced production flow.This study aims to understand, how the effectiveness of windows installations could be improved. By using a multiple case-study methodology, processes of several companies are compared and discussed. Further, suggestions for improvements are made for one case company. The results show that a replacement of the windows installation could (a) shorten the cycle-time of one wall by more than 10 %, (b) reduce the queueing time for the entire wall assembly process by more than 48 % and consequently (c) help to create a more balanced production flow.

Konferensbidrag (populärvet., debatt m.m.)abstract
- Due to devastating fires in several Swedish cities between 1838 and 1843, timber was not allowed to be used any more in bearing constructions for buildings with more than two floors. In 1994, the building code was changed towards functional requirements and timber could be used again in multi storey applications. However, this 150 year lasting prohibition let to the fact that building with timber in such applications barely developed. The market and the industry were used to steel and concrete, and mostly still are. Therefore, a strategy for more wood in construction was launched and implemented by the Swedish government in 2004, a.o. aiming at increasing the competition of building materials and -techniques. Here, prefabrication in an industrialized way was highlighted. Additionally, more Swedish wood should be processed domestically to save and provide jobs, but also to meet environmental concerns about reducing the CO2 footprint (Schauerte 2009).Regarding the implementation of that strategy, the Minister for Communications and Regional Policy in the Ministry of Industry, Employment and Communications, Ulrika Messing, stated that regional innovators and entrepreneurs would be of utmost impor- tance to reach the set up goals. Here, Växjö municipality comes into play.

Digital competence – state of the art and future needs in the Swedish wooden house manufacturers : SHS rapportnr: 30103
- 2023
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- The aim of this pilot study was to identify the existing level of digital competence and skills at wooden house manufacturers and to understand the future perceived needs they have in relation to these competences. This is motivated by the acknowledgement that digitalization has been emphasized both as a critical necessity and significant challenge for this industry.The number of responding companies in the study is rather low, offering a partial snapshot of the current state of the industry and potential future directions. However, it does provide valuable insights and considerations for future strategies for digitalization of the industry.The wooden house manufacturing industry is facing challenges relating to the overall business cycle as well as the effects of war, inflation, and increased competition. Despite these challenges, the industry appears to be aware of the potential possibilities that digital technologies may offer. Overall, they are rather content with the current level of digitalization and the level of digital competence among their staff. At the same time, they realize the need to continue investing in hardware and software as well as continued enhancement of digital skills for the staff. Presently, only a very small portion of total investments in the industry is allocated to digitalization.Most companies employ similar technologies and a variety of similar strategies to enhance their competences. The primary focus in terms of digital competence lies in the areas of production, marketing, communication, and sales. Areas such as customer support, decision-making, testing, and certification are not prioritized. Most of these companies recognize the need of digital competence development for their staff to effectively use contemporary digital technologies. Furthermore, they see a growing demand for digital competence over the next three years, particularly in domains such as artificial intelligence (AI), cybersecurity, infrastructure, and social media/marketing.

Tidskriftsartikel (refereegranskat)abstract
- Wood buildings are considered as a viable option to support the effort minimizing the current housing shortage in Sweden. Companies trying to develop into this industry are needed to increase the use of prefabricated wooden elements, volumes or modules in an industrialized way. Suitable companies to make this development could be found amongst firms producing wooden single-family houses. These companies currently act on a highly competitive market with many companies offering relatively homogeneous products or services. Therefore, differentiation towards the wooden multi-family house industry could be considered as a long-term strategy, minimizing the economic distress and improving the survival of the company.The study is aiming at describing the development of economic distress and market concentration ratio in the Swedish industry for wooden single-family houses, for an eleven-year period from 2005 to 2015. The companies could be helped to understand, if and how the market concentration ratio and the economic distress are connected, linking company size to economic stability and efficient resource utilization. This will be conducted by applying Altman’s Z’-score model, grouping firms into a risk, a grey or a safe zone, combined with calculating the industry structure by means of the concentration ratio model. The required data were collected from the annual reports of the 51 relevant firms in the industry.

Konferensbidrag (refereegranskat)abstract
- As studies based on data from 2012 show, the Swedish market for wooden single-family houses is highly competitive, with many firms offering relatively homogeneous products or services. In order to serve the demand on that market, only 38 % of the existing firms actually were needed. Thus, an uneven distribution of resource utilization let to welfare losses. Yet since 2012, the demand on the market increased by more than 35 %, which potentially had an effect on resource utilization.This study is aiming at describing the development of the structure and concentration in the Swedish industry for wooden single-family houses, for a five year period from 2010 to 2014. This could help to understand, if and how market demand affects structure, concentration rate and consequently welfare loss due to resource utilization. The required data were collected from the annual reports of the 52 relevant firms in the industry. By means of the Herfindahl-Hirschman Index and the Herfindahl-Hershamann Number Equivalent, industry structure and concentration rate was calculated.The results will show how the industry structure and concentration rate developed from 2010 to 2015, the distribution of resource for welfare purposes and thus, how many firms there actually were needed to serve the market.

Konferensbidrag (refereegranskat)abstract
- The market for Swedish wooden single-family house producers is characterized by perfect competition, i.e. products are highly substitutional and firms mainly compete by prices. Variance in net profit margins, as a key number for profitability, for firms in this industry ranges by 60 %. As net profit margin is defined as net profit divided by revenue, these latter two directly affect net profit margin. Yet, leaving the obvious determining mathematical explanations aside, other factors might affect the profitability of the firms, showing, what distinguishes successful firms from less successful ones.This study is aiming at exploring the factors affecting the profitability of Swedish firms producing wooden single-family houses. By means of those factors, variances in net profit margins might be explained more thoroughly. Data from annual reports were collected from 52 firms in the industry and a correlation analysis performed.The results will show if there are factors that correlate with net profit margins and if yes, what explanatory power these factors have. This in turn might serve as an input for the firms’ strategic development towards a higher profitability of their businesses.

Tidskriftsartikel (refereegranskat)abstract
- Sweden is forecasted to grow its population with 1.1 million people over the next eight-year period, increasing the demand on the construction phase of housing units throughout Sweden. However, at present, 240 of Sweden's 290 municipalities show an existing deficit of available housing units in their regions, resulting in inherent difficulties fulfilling this demand utilizing the current production structure. Therefore, further utilizing wood as a building material could contribute to minimize the gap, as well as fulfilling the EU’s goals towards the Europe 2020 strategy and the EU forest strategies, focusing on development towards innovation, bio-economy, sustainable sourcing and use of raw materials. This study is aiming to identify drivers supporting the Swedish industry of wooden multi-family houses to enable market growth through competitive and sustainable strategies. The representatives within the building process identify drivers, how they perceive their effect on the companies’ abilities to develop based on long-term and short-term strategic impact. Thus, the goal is to find ways in which wooden multi-family houses could compete as a building solution, compared to established solutions, thereby increasing the market share in Sweden. The methods used in this study is surveys distributed to representatives from municipalities, developers, contractors, architects and real estate companies.The result identifies three change drivers influencing the industry development for wooden multi-family houses in Sweden: technological-, knowledge- and environmental- drivers. These drivers have an effect on the companies’ ability for successful new product development and for development of sustainable strategies towards market growth for wooden multi-family houses.

Identifying market mobility barriers for wooden single-family house producers to enter the multifamily segment
- 2018
-
Ingår i: Social Influences. - : Forest Products Society.
-
Konferensbidrag (refereegranskat)abstract
- In the past decades, the housing shortage in Sweden accumulated to a level that led to acute problems for many people combined with continuously rising housing prices. The market for single-family houses, where wood dominates with 85 – 90 % of market share, is highly competitive with many companies offering relatively similar products or services. To serve the demand on that market, only 38 % of the existing companies were needed. One way to tackle the existing housing shortage, and to develop new business opportunities, could be to get more companies from the single-family house industry to produce multi-family houses. Current competence in prefabricated house production could be utilised, yet, other areas could act as barriers for these companies. The aim of this study is to identify potential market mobility barriers for Swedish companies currently producing wooden single-family houses to develop towards the construction of multi-family houses. This will be conducted by initial interviews with decision makers in those companies, combined with a survey-study covering companies within the industry. The results show that the main market mobility barriers are related to the strong market presence of traditional building materials, lack of knowledge by the market of wood as a suitable building material and the importance of governmental guidance and actions.
