    Färdplanför effektivisering och egenförsörjning av energi i lantbruket2018Report (Other academic)
    Abstract [en]

    The greenhouse gas emissions connected to energy use in the Swedish agriculture (excluding greenhouse cultures) represents 0,6 Mton CO2eq which is about 4% of the agriculture greenhouse gas emission in Sweden (Jordbruksverket, 2018). The “All Party Committee for environmental objectives” (miljömålsberedning) suggested that by 2045 Sweden should has a zero-net-emission of greenhouse gases. The parliament (Riksdag) adopted this political framework for climate issues which entered into force the 1st of January 2018. To reach this ambitious goal, all sectors including agriculture must undertake measures.

    The project developed a roadmap in the form of a list of measures leading the Swedish agriculture towards a sustainable status in line with the Swedish Environmental Goals. This roadmap was developed using a backcasting methodology. It means that first the goals were set and then the measures needed to move from the present status to the goals were developed. Based on political goals as well sustainability principles, a vision of the future for Swedish agriculture has been developed. The vision is:

    In the future, agriculture is energy effective, independent from fossil resources, deliver energy to the society and is profitable. Agricultural enterprises have access to knowledge, competences, and decision support. Collaboration within the agricultural sector as well as with other sectors is comprehensive for energy.

    To analyse the current situation, four studies were implemented within the project: (i) a survey of farmers view and interest, (ii) a survey of agrarian education, (iii) identification of bottlenecks with research and development (R&D), and (iv) an analysis of how relevant tools for energy are communicated. A selection of observation positive for the energy and climate questions are as follow: more agricultural enterprises have solar cells today than three years ago, 25% of the respondents have attend an eco-driving course, large farms have done most energy surveys and, investment in fossil free energy is seen as positive for both enterprise and the environment. Negative observations are that farmers miss a long-term regulation for energy production and feel a lack of knowledge about energy efficiency and production. Only 8% of the respondents uses high blends biofuels. In addition, respondents have expressed a lack of collaboration and inquire for a joint communication for R&D results concerning energy efficiency and production. In the agrarian education the interest in energy efficiency and production is low.

    A range of measures contributing to reach the vision were suggested. These measures vary between different communication strategies, improved advisory services and need for regulatory simplification to minimize the hassle with permissions and administration. Simple and accessible key figures as well as better statistics would make it easier to follow the different energy flows. It is up to decision-making authorities, advisory organisations, institutions of higher education, agricultural organisations and agriculture themselves to implement these measures.

    Accelerating Open Digital Innovation in the Automotive Industry: Action Design Research in Progress2017Conference paper (Other academic)
    Abstract [en]

    As digital technology becomes embedded in the core of customer offerings, companies find themselvesbeing part of dynamic networks and must develop more open and distributed innovation processes.However, important and mature industrial domains, such as the automotive sector, find it difficult tofully utilize digital technologies due to closed innovation processes. Therefore, automotive companiestry to attract external software developers by establishing new organisational forms for open digitalinnovation. Yet, the understanding of the problems that the organizational forms are expected to solve,how the organizational interventions should be designed and their effects on digital innovation areuncertain. Therefore, our goal is to contribute with knowledge of how the automotive industry canaccelerate digital innovation by mindfully selecting and designing appropriate organisational interventions for open digital innovation. In this research in progress paper, we present a two-year action design research project and contribute with initial empirical results on the problems with open digitalinnovation in the automotive industry, a comparison of organizational forms for open digital innovation, based on a literature review and an assessment of the organizational forms’ potential to overcomethe problems. The next step is to perform a structured literature review, and to design and implementan organizational intervention to facilitate a first iteration of externally initiated innovation cases.

    Solceller som solavskärmning: Forskning, utveckling och demonstration2018Report (Other academic)
    Abstract [en]

    This report presents the implementation, results, discussion and conclusions of the project "Solar Shading in an Overall Perspective - From Energy Efficiency to Energy Production and from Product to Architecture". From 2015 to 2018, companies from the solar shading and solar PV industries, together with architects, researchers, contractors and property managers, have explored the area in order to increase interest, knowledge and acceptance for solar shading in various important target groups. A strong focus has been on the combination of solar cells and solar shadings in a product named electricity generating solar shading. Among the results is a literature summary and an experience feedback from eight installations, as well as a database of examples from about 70 solar-shading installations, most of which are built up of solar cells. A development effort in collaboration between solar shading- and solar PV companies has resulted in several new products that were evaluated in the project and now being demonstrated at RISE's office in Borås.

    Durability tests of wood materials related to constructions in Björnlandet National Park

    The aim of the present study, primarily initiated by the Swedish Environmental Agency, is to study the durability of different wood materials related to and used in constructions in Björnlandet National Park in northern Sweden (63°97´N, 18°05´E), completed during 2014 and 2015. Of particular interest is to determine the durability properties in a scientific way of local materials used, such as mountain-grown Norway spruce and locally grown Scots pine and larch. The effect on the performance of charring and superficial wood-tar treatment is also studied.

    The study consists of a laboratory test according to ENV 807, a field trial according to EN 252 and a service trial on-site in the national park, including constructions such as load-bearing piles, ramps, foot-bridges and platforms. Results from the tests according to ENV 807 and EN 252 as well as the initial inspection of the constructions and components of different materials are presented in this report.

    During the initial inspection of the constructions on site, then in use for 1-2 years, no decay was found besides a small initial attack on one single pile of larch.

    The accelerated tests in laboratory and field have provided interesting information on the durability properties of the different materials and the ranking between them from a durability point of view which can be concluded as follows:

    • The local materials show moderate durability with marginal differences between the materials, with the exception of the spruce materials which show lower durability, comparable to the durability of pine sapwood.

    • Heartwood of locally grown pine and larch show basically equal durability properties.

    • Slow-grown wood will not enhance the durability properties.

    • Superficial treatment with wood-tar contributes so far to a somewhat increased durability. However, the primary positive effect is most certainly owing to the smell and appearance of wood treated with wood-tar, which in certain environments contributes to a positive perception. Charring does not add any value from a durability point of view.

    It is important that the results of the laboratory and field tests are interpreted with some care and common sense. The relatively extensive decay achieved with all materials but the preservative-treated wood does not necessarily mean that the constructions will be subject to early decay. With respect to the geographical location of Björnlandet National Park in the inland of northern Sweden, where the decay hazard in general is moderate, the local materials can thus be expected to have a reasonably long service.

    However, results from the tests indicate that efforts to select local materials/use "traditional" treatments most certainly will not result in longer service life than can be achieved with corresponding materials commercially available.

    Finally, it is pointed out that:

    • Avoiding moisture traps by correct design of components and constructions is vital for the service life when "traditional" local materials and treatments are used.

    • Preservative treatment will in general give critical wooden constructions a longer service life. The use of untreated wood involves more uncertainty with expected service life. Regular inspections and maintenance are therefore particularly important for constructions critical to personal safety (e.g. foot bridges, ramps) or infrastructure (e.g. bridges).

    Urgent future objectives to complete are the inspections of the field trial until remaining stakes have been exposed for five years, and to follow up the service trial in Björnlandet National Park with inspections in 4-5 years, i.e. in 2022 or 2023 in order to confirm or reassess the preliminary conclusions.

    Low frequency sound pressure fields in small rooms in wooden buildings with dense and sparse joist floor spacings2015In: Proceedings of the Internoise 2015 conference: 44th International Congress and Exposition on Noise Control Engineering / [ed] Maling G.,Burroughs C., The Institute of Noise Control Engineering of the USA , 2015, 2015Conference paper (Refereed)
    Abstract [en]

    Using wood as the main construction material is a potential solution to achieve sustainable buildings. Previous research has shown that frequencies below 50 Hz are of significant importance for the perception of impact sound by residents living in multi-story buildings having light weight wooden frameworks. The standards used for impact sound measurements today are developed for diffuse fields above 50 Hz. For instance due to requirements concerning wall reflections, these methods are not applicable for low frequencies within small rooms. To improve measurement methods, it is important to know the nature of the full sound distribution in small rooms having wooden joist floors. Here, impact sound measurements with microphone arrays are made in two small office rooms having the same dimensions. The rooms represent two extremes in design of joist floors; one with closely spaced wood joists and the other with widely spaced joists. An impact ball is used for excitation the room being measured from the room above. The results show that there are significant variations in the sound pressure, especially in the vertical direction. Here, measurement techniques of impact sound in the low frequency range in small rooms in wooden buildings are evaluated and potential improvements are proposed.

    The Blue Move for a Green Economy : Behovsstudie och teknikkartläggning av arbetsmaskiner2018Report (Other academic)
    Abstract [en]

    The Blue Move project aims to generate an increased demand for hydrogen as a fuel and investigate the business potential of heavy machinery in the Öresund-Kattegatt- Skagerrak (ÖKS) region, contributing for renewable energy in the transport sector to increase. The use of heavy machinery generates significant carbon dioxide emissions and local air pollution. By using machines with batteries and/or fuel cells instead of combustion engines, local air pollution and climate impact from the machines can be reduced. Electrification also reduces noise and vibration problems, contributing to an improved local and working environment. Customers' requirements are changing and within the near future some clients will only buy zero-emission vehicles. For example, many municipalities have high environmental targets and aim to be climate neutral and fossil fuel-free by 2030. Setting the requirements for public procurement, municipalities and regions become very important players in the process of converting to fossil fuel-free working machines. Electrification is on the rise and the development is fast, which, in addition to the environmental benefits, allows many benefits such as increased service life and a reduced number of components. The cost and character of the service of the vehicles will also change. The choice between electrical operation with batteries or with fuel cells depends on the cost, weight and space requirement for the current energy need. When operating on fuel cells, the heavy machinery can be quickly fueled, and it has an unchanged performance from full to empty tank. The use of fuel cells is also space-saving compared with fullelectric machines since areas for charging or battery change are not required. Today there are both battery and fuel cell - electric heavy machinery available on the market. This report gives an overview of available equipment, but also prototype and demo machines. Both a continued technical development and an increased market share for emission-free vehicles are required to meet future environmental goals. In order to achieve success, it is important that customers and manufacturers meet.

    Rammevilkår og strategier for hydrogen i transportsektoren2018Report (Other academic)
    Abstract [en]

    The Interreg project Blue Move promotes increased use of renewable energy to replace fossil fuels in the Øresund-Kattagat-Skagerrak (ØKS) region. International, national, regional and local framework conditions, strategies and measures are crucial in making the transport sector emission-free. Such framework conditions and strategies providing examples of what can be done at local and regional level to promote emission-free transport are described including analysis of business models for the use of hydrogen for transport, as well as proposals for strategic roadmap bullet points and a concrete checklist for municipalities that wish to facilitate emission-free transport. The purpose of the report is to help both public and private stakeholders succeed in introducing hydrogen as a fuel. A tight interaction between the public and private sector is seen crucial to secure a successful outcome. Municipalities and counties/regions have important roles as facilitators and first movers including hydrogen vehicles in their own car fleet and for public transport. Through its purchasing power, public authorities can drive development in the right direction by demanding the use of emission-free fuels. At the same time, the private sector has important roles in building and operating infrastructure, as well as adopting hydrogen fuelled passenger cars and utility vehicle.The report describes framework conditions and strategies for reducing greenhouse gas emissions from transport at EU level and down to local level. There is a strong connection between these strategies; To achieve the EU goals, each country must set its own goals. Similar, to reach the national targets, measures must be taken at local and regional level. In Chapter 3, the EU goals and strategies are described. Chapter 4 addresses the national framework conditions and strategies in Sweden, Denmark, and Norway. It appears that there are great variations in which instruments are used in the countries to promote emission-free transport. In Chapter 5, a range of insights into regional and local strategies, action plans and measures are provided. In an early phase, sustainable business models might be hard to find without financial support both for private and public stakeholders. In a Blue Move feasability study [BLUE MOVE WP3] the potential of hydrogen as an energy carrier in the ØKS region was illuminated through several case descriptions. In Chapter 6, a brief analysis of the business models described by these cases is provided. Then, a numerical example is presented illustrating the profitability of a small hydrogen station related to a fixed refuelling demand. Next, the possibility of infrastructure development in elucidation of construction machinery and coordinated initiatives in the field of heavy transport are described. At the very end of the chapter, a study of the potential for temporary hydrogen filling stations in Norway and Sweden is summarised. Finally, the report provides some practical advice on how to get more hydrogen on the road. Here, 10 roadmap bullet points at a slightly higher level for what and how to focus are given. Furthermore, a concrete 10-point checklist for municipalities is presented. The municipalities play an important role in transforming their own vehicle fleet and facilitating that private sector and its residents being able to run emissions-free. Our aim is that the report will inspire both public and private sector to plan and implement concrete measures to increase the use of hydrogen for transport and by these means achieve its goals of reduced greenhouse gas emissions.

    Wind effect on internal and external compartment fire exposure2018Report (Other academic)
    Abstract [en]

    Changes of buildings regulations regarding the allowable height of mass timber structures in North America have been proposed. The proposed changes are to a significant extent based on real scale fire experiments of compartments that have been performed in laboratories in which the influence of wind is negligible. It has, however, been questioned whether the proposed regulations are relevant for realistic scenarios with external wind loads acting on the building during a compartment fire.

    The study discussed in this report involves a review of previous literature, analysis of available test results and single zone modeling to study potential effects of external wind on the internal and external exposure of fires in compartments with exposed CLT.
