    Linking socio-technical transition studies and organisational change management: Steps towards an integrative, multi-scale heuristic2019In: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, p. 359-368Article in journal (Refereed)
    Abstract [en]

    While the role of agency is widely acknowledged in socio-technical transition research, there remains a research gap on agency in transitions and a call for studies using an actor-centred approach to transition studies. In response to this call, this paper addresses the role of actors and, particularly, organisations in transitions. It examines the role of organisational change in socio-technical sustainability transitions and, more specifically, how transition initiatives may trigger and support these changes in organisations and systems. For this purpose, the paper draws on literature from both transition studies and organisational change management (OCM) to build a multi-scale, integrative theoretical heuristic. This addresses drivers and barriers for organisational change as an integral part of transition processes, connecting the micro level of the individual, the meso level of the organisation and the macro level of the broader system in which the organisation is located. With the goal of illustrating the links between OCM and transition studies, this paper empirically examines the impact of Region 2050, a large, multi-organisation transition initiative in Sweden, in terms of creating change within the organisations involved. The main focus is on how the organisations acquire the new knowledge and capabilities required for improving regional planning for sustainability. The empirical study identifies leverage points at the micro-, meso- and macro-levels, which may be used in order to change strategic planning processes. Three different theoretical concepts from transition studies and OCM that could help to foster long-term planning are also identified: (1) the macro-level of institutional plurality and its connection to the meso- (organisational) level; (2) collaboration as a key success factor on the organisational level; and (3) at the micro-level, the roles of individuals as change agents and boundary spanners. Overall, the case highlights the merits of the OCM literature for transition studies and their emphasis on understanding interacting processes operating at multiple scales.

    Sharing Spaces in the Sharing Economy - to save energy, increasewell-being or boost inn vation? How do new initiatives align with energy transition?2017In: BIWAES - Biennial International Workshop Advances in Energy Studies, Graz, 2017Conference paper (Other academic)
    Abstract [en]

    Our paper is informed by the recent interest in how the sharing economy and related initiatives mayact as drivers for energy transition and increase well-being and social sustainability in smart sustainable city contexts. We take the example of temporary buildings that for a limited time period offer shared public spaces for public events in the city. Such initiatives are often linked to quadruple helix initiatives in which a local city council, industry and academia join forces to engage citizens in the energy and climate debate, with a temporary building structure as the focal point. The paper argues that such energy initiatives are valuable in terms of social sustainability since they create additional public space for the benefit of citizen debate; contribute scalable solutions and effective infrastructure that can promote energy awareness among citizens. However, there is limited scientific evidence, and a lacking awareness, of the energy efficiency and climate comfort relating to temporary buildings for public use. Our preliminary results show that such factors risk to obscure the well-intended objectives of quadruple helix initiatives to support energy transition. The revealed problems of a Stockholm use case suggest that in spite of significant social and economic impact resulting from curated public events which attracted an unprecedented number of visitors, energy consumption, climate comfort and indoor air quality are nevertheless important factors that also must be considered in the design and implementation of temporary building structures. The paper concludes that better climate controlshared economy thinking is necessary at theearliest stage of a planning process, for temporary buildings to be successful.

    Similarity problems for steady state geothermal systems2014In: International Journal of Fluid Mechanics Research, ISSN 1064-2277, Vol. 41, no 6, p. 547-555Article in journal (Refereed)
    Abstract [en]

    Increasing energy efficiency of the geothermal systems (GS) is an important task for further development and implementation of the geothermal energy for industrial and domestic heating and cooling. Achieving the higher efficiency, in its turn, requires insight into thermodynamic interaction of all elements of GS. Mathematical modeling of such systems, as well as the development of similarity methods for such modeling is highly relevant because of the high cost of the GS. The presented in the paper mathematical model of a strongly non-equilibrium thermodynamic systems Ground - Borehole Heat Exchanger - Ground Source Heat Pump has been elaborated to describe the energy exchange between the ground, BHE and GSHP. Based on this model a stationary problem of such system operation has been solved. A new type of non-equilibrium spatial scales for this problem, not depending on its geometric parameters and that are determined by energy characteristics of GS are introduced. It is shown that in the special variables considered problem is characterized by a unique dimensionless parameter - the ratio of the thermal conductivity of the ground and brine. This allows us to formulate new approaches to GS modeling.The physical interpretation of the received results is provided.

    A phenomenological theory of steady-state vertical geothermal systems: A novel approach2019In: Energy, ISSN 0360-5442, Vol. 175, p. 23-35Article in journal (Refereed)
    Abstract [en]

    This paper proposes a novel approach for studying the stationary energy characteristics of vertical geothermal systems (VGS) using stationary two-dimensional phenomenological mathematical theory. The approach describes VGS as a single, strongly nonequilibrium thermodynamic system consisting of a soil, a borehole with secondary fluid and a ground source heat pump (GSHP). The model uses continuity conditions for temperature and local heat fluxes between VGS components. The theory includes a special class of nonequilibrium spatial scale of VGS that is independent of its geometrical parameters. It is determined by the energy characteristics of the heat pump and the thermodynamic properties of soil and secondary fluid. Spatial variables can be chosen so that the energy characteristics of the VGS depend on only one dimensionless parameter (a similarity parameter), the thermal conductivity ratio of soil to secondary fluid. This considerably simplifies interpretation of theoretical and experimental results obtained using similarity methods. We show that, under real conditions of VGS functioning, the value of this similarity parameter varies from 0.5 to 10. The approach can be used to optimise GSHP systems to obtain energy of the required amount and quality to capitalise on heat pumps as ‘flexible agents’ in Smart Energy Systems.

    On the role and potential of IoT in different industries Analysis of actor cooperation and challenges for introduction of new technology2017In: 2017 JOINT 13TH CTTE AND 10TH CMI CONFERENCE ON INTERNET OF THINGS - BUSINESS MODELS, USERS, AND NETWORKS / [ed] Falch, M, IEEE , 2017Conference paper (Refereed)
    Abstract [en]

    In this paper we study how IoT technology can be introduced and used in different sectors; industrial IoT, smart energy, smart homes, smart cities, health care and social care, sports and well-being. The research has given increased insights into opportunities and obstacles for the introduction of IoT in different sectors. The main obstacles are considered to be i) specific IoT solutions often tend to be a small part of the overall solution, ii) lack of knowledge about which overall services the IoT solution may be part of, iii) Fragmentation and insufficient scalability, iv) Distrust and hesitation among actors to share data and platforms and finally, v) fear of changing the own business model. The analysis of our cases indicates that most of the challenges occur due to the fact that the solutions initially have been developed using a single firm business model. In order to survive or grow a networked business model is needed.

    Abstract [en]

    We propose a new paradigm for public participation in urban planning, a field which presents significant challenges for public understanding and participation. Our approach is based on leveraging the rich diversity of meaning associated with cultural gestures, traditions, folklore, and rituals, and using them in augmented reality systems, in order for citizens' to explore, understand, and communicate the complex, systemic ideas and concepts associated with urban planning. At an immediate level, this approach holds the potential for enabling increased public awareness of what is at stake in urban planning - both on the part of citizens and on the part of public officials, policy-makers, and decision-makers - and consequently enhancing understanding and improving participation in public life and citizenship. It may also open up a new field of research and development in human-computer interaction, to leverage the richness of meaning and modes of expression which exist in various cultures and societies, rather than ignoring them and imposing dumbed-down or prescribed command methods. Thus, it aims to facilitate new levels of empowerment of users in the use of digital systems and data. The active utilization of cultural meaning in gestures, rituals, and social practices may also support and promote better inclusion and participation of minority groups and migrant communities in contemporary, technology-rich life.

    being scared is not enough! motivators for education for sustainable development2013In: Sustainability Assessment Tools in Higher Education Institutions: Mapping Trends and Good Practices Around the World, Springer Berlin/Heidelberg, 2013, p. 29-45Chapter in book (Other academic)
    Abstract [en]

    This chapter presents an overview of positive motivators for students, lecturers, and educational managers to prioritize Sustainable Development in education. Very often, we implicitly assume that students and colleagues should all be motivated by the great challenges that the world faces. And if they appear not to react sufficiently to these challenges, we sometimes tend to give these challenges an apocalyptic character. But is this the right motivator for students and colleagues to work on Sustainable Development? We all know that if you only use a stick and no carrot… So why don’t we use more carrots? The bureaucracy that comes with tools for checking/auditing/evaluating the (SD content of) programs/curricula is not particularly a strong motivator for university lecturers. And building courses that add another subject to the erudition of the graduate might not be the right motivators for students that want to make a difference. We are often still in the process of convincing university managers to add SD to the curriculum, convincing colleagues to address SD, and convincing students to pick SD electives and address SD in their projects. How to motivate them to do this when this gives them no direct personal reward and even might increase their workload? The paper will explore options to develop motivating educating by reviewing case studies on educational renewal in four universities. It concludes that there are various options for more motivating education. However, to fully utilize these options, more priority should be given to education © Springer International Publishing Switzerland 2013.

    Motivating students and lecturers for education in sustainable development2015In: International Journal of Sustainability in Higher Education, ISSN 1467-6370, E-ISSN 1758-6739, Vol. 16, no 3, p. 385-401Article in journal (Refereed)
    Abstract [en]

    Purpose - This paper aims at identifying factors that could contribute to the motivation of students in sustainable development (SD) education. The underlying idea of the paper is that SD education is not always as attractive among students and lecturers as many would like it to be. Design/methodology/approach - The paper briefly reviews literature regarding behavioral change for long-term benefits. It identifies four motivators that could be effective to make people pursue longer-term objectives. It identifies if these motivators were present in five cases of successful SD education. Findings - The four motivators for students that were identified in the literature review (a sense of autonomy, a challenge of reflection on the future role, connection with others, self-fulfillment, focus on the individual learning need) could be observed in the cases of successful SD education, although to various degrees. Individual autonomy in learning was not observed, but group autonomy was present in all cases. Research limitations/implications - The case studies were all electives. It is unclear how the motivators could work out in mandatory courses. Moreover, the curriculum as a whole will affect the success of single courses. Successful courses being "the exception" of the curriculum might be judged differently if they would be part of the curriculum in which such courses would be the main stream. Further research is required to check if the motivators are effective in mandatory and not specifically SD-targeted courses. It is also not clear how various motivators could be applied most effectively in a curriculum. Practical implications - The paper gives guidance to lecturers and educational managers to design attractive and effective SD education. Originality/value - The paper treats SD education from a novel perspective: how to convey a credible behavioral message, and how to motivate students for education for SD.

    Designing energy feedback for a local social network2019In: Energy and Buildings, ISSN 0378-7788, E-ISSN 1872-6178, Vol. 199, p. 88-101Article in journal (Refereed)
    Abstract [en]

    Engaged households are needed for the future ‘smart grids’ to function, but it is difficult to engage residents in their household electricity consumption. Building on earlier research suggesting that a local social network could provide a suitable context for energy feedback, this paper examines how feedback presented in a social network should be designed in order to be better understood by the residents and encourage long-term engagement. A review of the literature on design principles and cases where they had been implemented identified 24 principles. A prototype feedback design adapted for a local social network was made, based on design principles deemed suitable for the screens designed. End-user feedback on the prototype was collected through a stakeholder consultation workshop. In the workshop dis- cussions, 17 identified principles were mentioned and there was support for 15 of these, one was both supported and contested and two were contested. Based on comments and suggestions from end-users, a revised version of the feedback prototype was made for implementation in a pilot study in Sweden and Portugal.

    Integrating ecosystem services in the assessment of urban energy trajectories: A study of the Stockholm Region2017In: Energy Policy, ISSN 0301-4215, E-ISSN 1873-6777, Vol. 100, p. 338-349Article in journal (Refereed)
    Abstract [en]

    Urban development trajectories are changing towards compact, energy-efficient cities and renewable energy sources, and this will strongly affect ecosystem services (ES) that cities are dependent on but tend to disregard. Such ES can be provisioning, regulating and cultural ES, around which competition over land resources will increase with energy system shifts. Much of this can be foreseen to take place within urbanising regions that are simultaneously the living environment of a major part of the human population today. In order to inform critical urban policy decisions, tools for integrated assessment of urban energy and transport options and ecosystem services need to be developed. For this purpose, a case study of the Stockholm region was conducted, analysing three scenarios for the future urbanisation of the region, integrating a transport energy perspective and an ES perspective. The results showed that a dense but polycentric development pattern gives more opportunities for sustainable urban development, while the dense monocentric scenario has apparent drawbacks from an ES perspective. The methodology is compatible with a model integration platform for urban policy support and will thus enable integrated policy assessment of complex urban systems, with the goal of increasing their sustainability.

    Household responsiveness to residential demand response strategies - Results and policy implications from a Swedish field study2018In: Energy Policy, ISSN 0301-4215, E-ISSN 1873-6777Article in journal (Refereed)
    Abstract [en]

    To realize the benefits of smart grids, residential demand response (DR) aims to increase demand flexibility by influence household electricity consumption. Although price-based DR programs have shown potential, there is a need to further investigate the effectiveness of DR in energy strategy and policy development. The evaluation of DR has focused on the impact on overall power demand, assuming that consumers are economically rational decision-maker. However, recent findings suggest that consumer responses have been insufficient and calls have been made to identify novel evaluation approaches that better reflect the human dimension of energy consumption. Continuing this line of enquiry, this paper aims to investigate the effectiveness of DR and explore the potential of environmental incentives for increased consumer engagement. We propose an interdisciplinary evaluation framework to understand variations in household responsiveness to DR strategies, which is tested in a Swedish DR field trial covering 136 households during 2017. Results suggest that the effectiveness of DR varies widely across household type; ranging from substantial reductions in overall consumption and during peak periods, to increases in consumption during peak periods. Furthermore, a clear favor of price incentives, compared to environmental incentives, as the most efficient strategy to increase demand flexibility was observed.

    Data-driven strategic planning of building energy retrofitting: The case of Stockholm2019In: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 233, p. 546-560Article in journal (Refereed)
    Abstract [en]

    Limiting global warming to 1.5 degrees C requires a substantial decrease in the average carbon intensity of buildings, which implies a need for decision-support systems to enable large-scale energy efficiency improvements in existing building stock. This paper presents a novel data-driven approach to strategic planning of building energy retrofitting. The approach is based on the urban building energy model (UBEM), using data about actual building heat energy consumption, energy performance certificates and reference databases. Aggregated projections of the energy performance of each building are used for holistic city-level analysis of retrofitting strategies considering multiple objectives, such as energy saving, emissions reduction and required social investment. The approach is illustrated by the case of Stockholm, where three retrofitting packages (heat recovery ventilation; energy-efficient windows; and a combination of these) were considered for multi-family residential buildings constructed 1946-1975. This identified potential for decreasing heat demand by 334 GWh (18%) and consequent emissions reduction by 19.6 kt-CO2 per year. The proposed method allows the change in total energy demand from large-scale retrofitting to be assessed and explores its impact on the supply side. It thus enables more precisely targeted and better coordinated energy efficiency programmes. The case of Stockholm demonstrates the potential of rich urban energy datasets and data science techniques for better decision making and strategic planning.

    Data-driven building archetypes for urban building energy modelling2019In: Energy, ISSN 0360-5442, E-ISSN 1873-6785, Vol. 181, p. 360-377Article in journal (Refereed)
    Abstract [en]

    This paper presents an approach for using rich datasets to develop different building archetypes depending on the urban energy challenges addressed. Two cases (building retrofitting and electric heating) were analysed using the same city, Stockholm (Sweden), and the same input data, energy performance certificates and heat energy use metering data. The distinctive character of these problems resulted in different modelling workflows and archetypes being developed. The building retrofitting case followed a hybrid approach, integrating statistical and physical perspectives, estimating energy savings for 5532 buildings from seven retrofitting packages. The electric heating case provided an explicitly statistical data-driven view of the problem, estimating potential for improvement of power capacity of the local electric grid at peak electric power of 147 MW. The conclusion was that the growing availability of linked building energy data requires a shift in the urban building energy modelling (UBEM) paradigm from single-logic models to on-request multiple-purpose data intelligence services.

    Energy performance certificates — New opportunities for data-enabled urban energy policy instruments?2019In: Energy Policy, ISSN 0301-4215, E-ISSN 1873-6777, p. 486-499Article in journal (Refereed)
    Abstract [en]

    Energy performance certificates (EPC) were introduced in European Union to support reaching energy efficiency targets by informing actors in the building sector about energy efficiency in buildings. While EPC have become a core source of information about building energy, the domains of its applications have not been studied systematically. This partly explains the limitation of conventional EPC data quality studies that fail to expose the essential problems and secure effective use of the data. This study reviews existing applications of EPC data and proposes a new method for assessing the quality of EPCs using data analytics. Thirteen application domains were identified from systematic mapping of 79 papers, revealing increases in the number and complexity of studies and advances in applied data analysis techniques. The proposed data quality assurance method based on six validation levels was tested using four samples of EPC dataset for the case of Sweden. The analysis showed that EPC data can be improved through adding or revising the EPC features and assuring interoperability of EPC datasets. In conclusion, EPC data have wider applications than initially intended by the EPC policy instrument, placing stronger requirements on the quality and content of the data.

    Modular participatory backcasting: A unifying framework for strategic planning in the heating sector2019In: Energy Policy, ISSN 0301-4215, E-ISSN 1873-6777, Vol. 124, p. 123-134Article in journal (Refereed)
    Abstract [en]

    This study proposes a novel framework, modular participatory backcasting (mPB), for long-term planning in the heating sector. The mPB framework is based on participatory backcasting (PB) and integrates principles of modularity, participatory modelling, and transdisciplinarity. We discerned for mPB 13 modules that can be arranged according to the purpose and specifics of each planning process. The design of the mPB framework and its implementation are presented for the cases of participatory strategic planning processes to achieve sustainable heat provision by 2050 in a Ukrainian city (Bila Tserkva) and a Serbian city (Nis). The results show that mPB allows adaptability to local contexts and limitations through exclusion, augmentation, substitution, splitting and inverting properties of modularity; decreases the learning time for applying the framework in a novel context; increases the reproducibility and transparency of long-term energy planning processes; enables efficient integration of quantitative methods into the participatory process; and advances collaboration between academia and society. The proposed framework is beneficial for advancement of local planning and policy-making practices by creating strategies with a wider support of stakeholders. It could also be useful for further research through cross-case analysis.

    Strategic planning for sustainable heating in cities: A morphological method for scenario development and selection2017In: Applied Energy, ISSN 0306-2619, E-ISSN 1872-9118, Vol. 186, no Part 2, p. 1115-1125Article in journal (Refereed)
    Abstract [en]

    The transition to more sustainable heating systems requires socio-technical approaches to strategic planning. Scenario development plays a key role in strategic planning, as the process supports the development of future visions and actions required for their realisation. However, new approaches to scenario development are required to address the limitations of conventional scenario development methods, such as the cognitive barriers of ‘groupthink’, reluctance to consider ‘outside-the-box’ options, handling of complexity, and ad hoc scenario selection and general non-transparency of scenario development processes. This paper describes the development and implementation of a novel method for scenario development and selection in the context of participatory strategic planning for sustainable heating in cities. The method is based on the morphological approach and a number of scenario criteria including transparency,reliabilitycoveragecompletenessrelevance/densitycreativityinterpretabilityconsistencydifferentiation and plausibility. It integrates creativity workshops and interdisciplinary stakeholder participation to enhance the ownership and legitimacy of the scenarios. The approach entails the generation of a complete space of scenarios for heating systems and reduction of this space using cross-consistency analysis and project-specific requirements. Iterative development and implementation of the method is illustrated using two participatory backcasting projects focused on strategic planning for providing a comfortable indoor climate for Bila Tserkva, Ukraine, and Niš, Serbia by the year 2030. The results demonstrate that the method helps overcome the limitations of conventional approaches to scenario development and supports rigorous and transparent selection of a scenario set for participatory analysis. The method fostered the elicitation of consensus-based scenarios for more sustainable heating systems in both cities with regard to the quality of indoor comfort, environmental impact, resource efficiency and energy security.

    Exploring scenarios for more sustainable heating: The case of Nis, Serbia2016In: Energy, ISSN 0360-5442, E-ISSN 1873-6785, Vol. 115, p. 1758-1770Article in journal (Refereed)
    Abstract [en]

    Sustainability transformation of the heating sector is recognised as being essential for reaching climate and environmental targets while improving the quality of life in cities worldwide. Participatory strategic planning enabled by scenario methods can be an important tool to guide this transformation, but methods for qualitative scenario analysis supporting stakeholder participation must be further developed and tested in the context of different cities. This paper presents results from integration of urban energy system modelling into the participatory strategic planning process implemented in the city of NE, which suffers problems typical of the heating sector in Serbia and the Western Balkans. The aim was to explore how the scenarios developed by local stakeholders could transform the NB heating system by 2030. Five scenarios developed within participatory backcasting project and a BAU scenario were analysed in terms of decarbonisation, energy security and energy efficiency using Long-range Energy Alternatives Planning System (LEAP). A final scenario "Efficiency for the green future" designed by the stakeholders for implementation in the city included high standards of energy efficiency in buildings, increased share of renewables in the heating energy mix, expanding the district heating system, deploying smart technologies and green architecture. The LEAP model demonstrated that this final scenario could lead to achievement of the desirable future vision developed by stakeholders for NB, through substantial improvements in energy efficiency and energy security, and to considerable emissions decreases by 2030 in comparison with the base year (2010) and the BAU scenario.
