Abstract [en]

Swedish forest growth can be increased through intensive forestry practices, enabling an increased use of forest biomass for climate-change mitigation. However, the diffusion of such practices depends on the forest owners' adoption of them. We study Swedish private forest owners' perceptions and intentions with respect to increasing forest growth by adopting exotic tree species. The results of a mail-in questionnaire survey show that although a majority of forest owners desire increasing forest growth, most owners have only a basic understanding of exotic tree species and a smaller proportion is interested in adopting them. The intention to adopt exotics seems to depend on the perceived performance of the species with respect to the economic aspects of forest management rather than on environmental or recreational concerns. Whereas a knowledge gap among the private forest owners regarding how to increase forest growth is implied, forest owners with higher self-rated knowledge of forestry and exotics have stronger intentions to adopt such species.

Abstract [en]

Purpose - The purpose of this paper is to analyse the influence of regulations, perceptions, and promotions on the emergence of an innovation system for wood-framed multi-storey buildings in Germany, Sweden and the United Kingdom (UK). Design/methodology/approach - This descriptive paper made a qualitative analysis of information collected mainly from secondary sources such as reports, newspapers, journal publications, conference proceedings and general internet search. Findings - Results showed that the conditions for market growth of multi-storey construction seemed to be the most favourable in Sweden followed by the UK and Germany. The regulations are stringent in Germany, followed by the UK and Sweden. In all countries, the construction professionals seemed to have negative perceptions regarding engineering properties of wood. Similar negative perceptions exist among the general public in Germany and the UK, but not in Sweden. The wood construction promotional activities in Germany and the UK are directed to all types of houses, while in Sweden multi-storey buildings are targeted. Research limitations/implications - An important implication of this paper was that it highlighted the usefulness of cross-country surveys at the European level, in order to better understand observed differences in the adoption of innovative systems. However, there might be shortcomings in the comparability of the information across the countries analysed because it was difficult to make an objective assessment of the claims made in some of the information sources. Also, there was varying and limited information about the survey methodologies used in some of the reviewed studies. Practical implications - The study showed that market intervention is needed to promote radical or really new innovations such as wood construction. The variations in the promotional measures undertaken partly explained the variations in growth of wood construction system in the three countries. Originality/value - The paper applied a theoretical framework on technology transition to analyse emergence of wood construction system in Germany, Sweden and the UK. The framework can be applied to analyse the development of wood construction system in other countries also. Copyright © 2012 Emerald Group Publishing Limited. All rights reserved.

Abstract [en]

A better understanding of general hindrances to the diffusion of innovations in the construction sector may help to improve the energy efficiency of buildings. This study uses a web-based questionnaire to collect information on Swedish architects’ perceptions of hindrances to the adoption of innovations in building construction. The responding architects characterise the Swedish construction industry as having a low level of innovativeness. The most influential hindrances to innovativeness were perceived as the focus on project costs instead of life-cycle costs, the economic risks that innovations imply, the focus on traditional engineering models, the construction industry’s tendency to use proven materials and methods, and contractors’ inability to adjust processes. In terms of the involved actors, construction clients were perceived to have the greatest influence on innovativeness, and stronger cooperation between the architect and construction client was recognised as important to facilitate innovativeness.

Abstract [en]

Use of wood frames from sustainable forestry instead of non-wood frames in multi-storey buildings can reduce primary energy use and carbon dioxide emissions in construction. However, construction actors might have different perceptions towards wood frames than towards steel and concrete frames. Such perceptions may influence the actors' decision to adopt wood frames. In this study we use a web-based questionnaire to assess Swedish architects' perceptions, attitudes and interest towards steel, concrete and wood frames in multi-storey buildings (n = 412). Results indicate that the responding architects find concrete the most suitable frame material in buildings of 3-8 storeys, mainly because of the performance of concrete with regards to the engineering aspects (e.g. stability and fire safety) that were considered important in the choice of frame material. Although wood is considered the least suitable frame material, the overall attitude towards, and interest in, using wood is positive and related to the perceived environmental benefits of wood. This may derive from an increased discussion of and information about the environmental impact of buildings. Wood may be perceived as new and innovative while not considered as adequately proven as steel and concrete with regards to engineering aspects.
