    Identifying bottlenecks in the photovoltaic systems innovation ecosystem – an initial study2018Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Solar energy is likely to play a major role in future renewable energy systems. One important part in that is the integration of photovoltaic (PV) systems into the built environment. Earlier studies show that the institutional framework plays a major role for achieving a broad implementation of PV systems. It has however also shown that the value network of PV systems needs to be understood and developed further. In that respect, earlier research on innovation diffusion into the built environment shows the necessity of involving and understanding key stakeholders. Stakeholder analysis may help in identifying key stakeholders but fail in assessing the stakeholders’ role in the value network as it does not, for example, take into account the relational effects. Innovation Eco Systems is an approach that has the potential to do this as it addresses the alignment structure of the partners needed for the value proposition to occur. The aim with this initial study is to address the use of innovation ecosystem as a way of assessing implementation of PV systems in the built environment. Two structured workshops with two key stakeholder categories, Clients and Suppliers, were held to identify the main barriers for a broader implementation of PV systems into the built environment in Sweden. The main results show that the earlier studies were right in that the institutional framework is a major factor, but also that the value network is important and that the problems in the value network is perceived somewhat different between the two categories. This suggests that it will be necessary to address the value network from the perspective of the actors by applying an innovation ecosystem analysis. It also helped in identifying other important stakeholders in the value network that will be needed to include in the future studies. To summarize, the findings of this initial study suggest that innovation ecosystem will address a more comprehensive picture on the implementation of PV systems in the built environment. However, to be able to identify bottlenecks and subsequent solutions to these bottlenecks further studies of the complete innovation ecosystem, with its stakeholders, is necessary. The ongoing project is currently carrying out these studies in a Swedish context.

    The Dark Side of Value-for-Money: How Public Procurement Affects Workers’ Safety in the Construction Industry2012Inngår i: Proceedings  of  the  CIB  W099  International  Conference  on  “Modelling  and  Building  Health  and  Safety” / [ed] George Ofri, Ai-Lin Teo & Imelda Krisiani Tjandra, Singapore: International Council for Research and Innovation in Building and Construction; National University of Singapore , 2012, s. 525-533Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Studies on shading behaviour of contractors have in the past been focused on lack of product quality and other factors affecting the customer. This study of 222 publicly procured road and railroad projects aim to analyse shading behaviour from a perspective of workers safety. The study shows, though with limitations in statistical power, that the number of reported incidents related to workers’ safety increases in projects with high numbers of bidders, i.e. projects under high competitive pressure, further the number of days of registered sick leave also increases with higher numbers of bidders. However, measures directly related to contractors shading behaviour do seem to increase prediction of number of accidents and sick leave days. It is suggested that public authority has to construct bid competitions in manners which does not necessarily aim at the best bargain but rather have a fair bargain approach balancing the goals of the contractor and the goals of the public client. This can be done by balancing the allocation of risks more evenly among the parties ex ante.

    Procurement Procedures as predictors for cost and time overrun in construction2012Inngår i: Proceedings of the 5th International Public Procurement Conference, Seattle, USA, August 17-19, 2012, 2012, s. 2796-2816Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The choice of procedure during public procurement is assumed to affect the overall result of the project. When studying the construction industry; delivery methods, payment systems and project specific variables may affect the end result. The question here is if project success is predicted by choice of procurement procedures. A survey was done on 222 road and railroad construction projects in Sweden between 2007 and 2010, collecting expected and actual empirical data on cost and time overruns and number of non-conformances from each project. The conclusion is that procurement procedures do not predict cost and time overrun nor do they predict number of non-conformances during inspection.

    Flervåningshus i trä: En undersökning rörande byggandet i Halland2017Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    Abstract

    This paper is based on interviews, a literature study and seminars. It describes the

    situation in Halland when it comes to multi-story housing built in timber. From 1874

    to 1994, Sweden had a regulation that prohibited construction of timber houses with

    more than two stories as a result of big city fires. After the regulation was revoked,

    people started to build multi-story houses in timber again. Compared to the rest of

    the country there was not that many built in Halland. Construction entrepreneurs

    here possess the right competence and it is close to the raw material. Even though

    that, there are only five multi-story houses built in the county.

    Result from this study shows that the main problem of implementing multi-story

    housing built in timber is biases and lack of knowledge. Many of the players in the

    construction industry do not base their decisions on fact when it comes to choose

    timber or not. This in combination with a lack of information regarding financial

    issues and unfavorable regulations has resulted in a slow development of the

    implementation of multi-story houses. The reasons behind this are discussed in the

    paper and some possibilities of change are presented.
