    Stormwater management and urban planning: lessons from 40 years of innovation2013Inngår i: Journal of Environmental Planning and Management, ISSN 0964-0568, E-ISSN 1360-0559, Vol. 56, nr 6, s. 786-801Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Urban planning is widely advocated as an important way to encourage the more sustainable management of urban stormwater using alternatives to piped systems. This paper explores the way in which Swedish water professionals have opportunities to influence stormwater planning and the barriers that limit their participation in this process. Empirical evidence has been obtained from in-depth semi-structured interviews with urban water professionals from nine Swedish municipalities. The paper shows that there is a perception of the legal requirements related to the provision of drainage services that inhibits the utilisation of non-piped solutions. There are also reservations about a dichotomy that inhibits actions - is stormwater an issue for the planning department or for the water department? It is concluded that water professionals have unique opportunities to integrate stormwater management approaches within wider urban planning practice and hence are able to encourage the use of alternative systems that are more sustainable than using traditional pipes or sewers.

    An adaptive stormwater culture?: historical perspectives on the status of stormwater within the Swedish urban water system2012Inngår i: The Journal of urban technology, ISSN 1063-0732, E-ISSN 1466-1853, Vol. 19, nr 3, s. 25-40Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The purpose of the article is to analyze a number of historical explanations behind the slow process of change in stormwater management in Swedish urban planning and practice. We achieve this by studying three different periods of the long-term establishment of the Swedish urban water system over the nineteenth and twentieth centuries, developments which were strongly linked to stormwater. The article recognizes the social construction of the system, i.e., how it grew out of human desires and how it grew extensively during the twentieth century due to an expansive growth of system-supporting public initiatives. These included funding opportunities as well as the establishment of different institutions and organizations. The analysis indicates that in their current efforts to transform urban stormwater management in a more sustainable direction, policymakers and implementers ought to be encouraged by an increased awareness of this social construction; what humans by their desires once built up, they should also be able to transform. Still, an important implication is also the need for such transforming efforts to determinately break away, both physically and mentally, from the traditional pipe-bound system and system culture.

    By Design, from design guidance to built form2016Rapport (Annet vitenskapelig)
    Abstract [en]

    This paper explores the planning policy era of By Design: Urban design in the planning system: towards better practice through the lens of Planning Policy Guidance 1 (PPG1): General Policy and Principles and Planning Policy Guidance 3: Housing. The paper explores the objectives of urban design, as set out in By Design against PPG1’s objective to promote higher standards of urban design and PPG3’s objective to revise housing densities. Research takes a systematic approach to reviewing the evidence base available for the production of By Design and analyses density targets and urban design objectives against generic housing types of the day and four housing led development schemes delivered during the policy period. The paper argues that on density grounds, only two of the researched generic housing types delivered the density targets prescribed by PPG3, requiring the development industry to bring forward new models of development. The case study analysis establishes that the industry was able to adapt to the objectives of By Design with selected developments delivering the urban design objectives set out in By Design and density standards of PPG3. The paper concludes by arguing that whilst ‘By Design’ was extinguished as policy in 2012, its design objectives are still valid and may be relevant to new emerging dimensions related well-being as part of; Ease of movement and seasonal climate change as part of; Quality of the public realm.

    Urban design of winter cities: Winter season connectivity for soft mobility2018Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    All across the world the form of the built environment is playing a crucial role as enabler or inhibitor for urban outdoor activity such as soft mobility. Urban form can make it more attractive for people to be mobile outdoors and playing a role in the public life, or it can put people off venturing outside. For winter cities, a question for urban design is how we can design environments that are attractive for outdoor activity in the winter season as well as summer and additionally how will climate change influence these aspects.

    The reason for studying this is the importance of understanding how, in relation to urban form, weather, seasonal variations, and climate change influences human outdoor activity. In this study the focus on outdoor activity is problematised around the concern that people spend a low percentage of their time outdoors in winter conditions. For society, the problem is that this trend and the related low levels of physical activity are associated with a range of health issues.

    To study this the main question for this research is what attracts and hinders soft mobility during the winter season and how can this knowledge underpin new considerations about urban design for connectivity in winter cities? To address this, the research methods focused on document studies, surveys, mental mapping, photo elicitation and semi-structured discussions.

    The study works at three scientific levels. Firstly, it seeks to understand the interrelationship between the built environment and people’s outdoor activity in winter. Secondly, it attempts to understand how connectivity for soft mobility in winter is being affected by weather and climate change. Thirdly, it seeks new ways of thinking about how the urban form can be designed to increase outdoor soft mobility in winter.

    The discussion and conclusions focused on the argument that in winter settlements, the winter season can alter spatial patterns and settlement organisation. Here it was argued that in these settlements the winter season can be an aspect of urban morphology and can be part of the process of shaping the public realm and its connectivity for soft mobility in winter.

    Toward an Integrated Model for Soft-Mobility2019Inngår i: International Journal of Environmental Research and Public Health, ISSN 1661-7827, E-ISSN 1660-4601, Vol. 16, nr 19, artikkel-id 3669Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    A key urban design challenge is to create built environments that encourage outdoor activityall year round. This study explores a new model for soft-mobility that places the interaction betweenthe urban form, the seasonal climate and climate change, and the individual at the center of people’ssoft-mobility choices, or in more general, their modal choice. The research methods used werecomparative studies of documents, surveys, mental mapping, and photo elicitation. These studieswere undertaken to research people’s outdoor activity in the built environment during the winterseason of a cold climate settlement. The results were analyzed against the three-dimensions of themodel. In the discussion it is argued that in places with significant climate variation, the interactionbetween the urban form, the season, and the individual together influence soft-mobility choices. Inturn, these interactions influence people’s level of outdoor activity and the individual health benefitssuch activity can aord. In conclusion, it is highlighted that all three dimensions of the model are in aconstant state of change and evolution, especially in relation to planning and development processesand climate change.

    Winter City Urbanism: Enabling All Year Connectivity for Soft Mobility2019Inngår i: International Journal of Environmental Research and Public Health, ISSN 1661-7827, E-ISSN 1660-4601, Vol. 16, nr 10, artikkel-id 1820Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This study explores connectivity for soft mobility in the winter season. Working with residents from the sub-arctic city of Luleå, Sweden, the research examines how the interaction between the built environment and winter season affects people’s use of the outdoor environment. The research questions for this study are, 1) how do residents perceive the effects of winter on an areas spatial structure and pattern of streets and pathways? and 2) what enablers and barriers impact resident soft mobility choices and use of the public realm in winter? Methods used were mental mapping and photo elicitation exercises. These were used to gain a better understanding of people’s perception of soft mobility in winter. The results were analysed to identify how soft mobility is influenced by the winter season. The discussion highlights that at the neighbourhood scale, residents perceive that the winter alters an areas spatial structure and pattern of streets and pathways. It was also seen to reduce ease of understanding of the public realm and townscape. In conclusion, it is argued that new and re-tooled town planning strategies, such as extending blue/ green infrastructure planning to include white space could help better enable all year outdoor activity in winter cities.

    Climatic barriers to soft-mobility in winter: Lulea, Sweden as case study2017Inngår i: Sustainable cities and society, ISSN 2210-6707, Vol. 35, s. 574-580Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Urban form can moderate the effects of weather on human movement. As such, the interrelationship between built environment, weather and human movement is a critical component of urban design. This paper explores the impacts of weather on non-motorised human movement (soft-mobility). Throughout we look at soft-mobility from the citizen’s perspective and highlight the barriers to soft-mobility in winter.

    The aim of this study was to test the traditional pallet of winter city urban design considerations. Those of solar-access, wind and snow management and explore other weather and terrain conditions that act as barriers to soft-mobility in winter. This study is based on survey responses from 344 citizens in the sub-arctic area of Sweden. Outcomes from the research highlight that rain, icy surfaces and darkness are today’s most significant barriers to soft-mobility in winter.

    Results from this study link changing barriers to soft-mobility in winter with climate change. The paper concludes that future urban design and planning for winter cities needs to consider a wider pallet of weather conditions, especially rain.

    Updating winter: the importance of climate-sensitive urban design for winter settlements2018Inngår i: Arctic Yearbook, ISSN 2298-2418Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This study explores winter settlement urban design principles to begin to identify climate related conditions that are affecting soft mobility (walking and cycling) in these communities.

    Winter communities have evolved lifestyles and means that fit with working and living with local conditions and seasonal variations. With climate change, however, comes evolving weather’s that these communities need to adapt too. These changes may present new risks and unexpected challenges to outdoor soft mobility in the community.

    Public policy highlights physical inactivity as a major health concern. For these communities, winter has always limited outdoor soft-mobility. Here, we understand that in winter outdoor activity can be reduced by weather and fear of accidents.

    People’s understanding of the barriers and enablers to soft mobility are also often based on experience and ability to detect environmental clues. To help winter communities maximise the opportunities for outdoor soft mobility and the wellbeing benefits this can bring, built environments need to be designed with an understanding of climate change. 

    This study explores barriers and enablers to soft mobility in winter and discusses them in light of climate change and human wellbeing. It is argued that established principles of urban design may require re-evaluation if we want to increase outdoor soft mobility in winter. Increases in physical activity could help reduce costs and pressures on health services by creating safer and more walkable communities. The paper concludes by suggesting that communities should focus on more context based winter urban design principles that account for ongoing climate change.

    Abstract [en]

    A solar heated area comprising 50 residential units is under construction. The system includes low-temperature space heating with seasonal ground storage of solar heat. Heating is supplied by 2 400 m{sup 2} of solar collectors and individual electrical heaters for supplementary heating. During the summer part of collected heat is stored in a borehole store with 100 boreholes drilled to 65 m depth. The groundwater-filled boreholes are fitted with double U-tubes. The average temperature of the seasonal store, about 60,000 m{sup 3} of crystalline rock, varies between 30 and 45 deg. C over the year. A floor heating system designed for a supply temperature of 32 deg. C provides space heating. The system is also equipped with buffer tanks for pre-heating of domestic hot water. The collectors will have favourable working conditions but the store is rather small and the estimated heat loss from the heat store is about 40% of collected solar heat. The average solar fraction is estimated to 70% and the resulting total heating cost is estimated to about 1 000 SEK/MWh ({approx}120{open_square}/MWh).

    Energy efficiency and preservation of 20th century architecture: The case of the Urbino University Colleges2018Inngår i: Conference Report. The 3rd International Conference on Energy Efficiency in Historic Buildings (EEHB2018), Visby, Sweden, September 26th to 27th, 2018., 2018, s. 182-190Konferansepaper (Fagfellevurdert)
    Abstract [en]

    This paper follows the discussion on the energy efficiency of heritage buildings by dealing with the task of preserving 20th century buildings and making them more sustainable. It is confirmed that a thorough analysis of each case is needed, since the cultural value of modern heritage risks being overwhelmed by the effort to improve its energy efficiency. The Urbino University Colleges are a masterpiece of the 20th century. They were designed by architect Giancarlo de Carlo, built between 1962 and 1983 and still host 1000 students. A conservation plan was outlined in 2016 with the aim of developing the long-term and sustainable preservation of such a huge complex. A specific goal in terms of sustainability was lowering the heating costs to save funds for conservation activities. The efforts were thus to balance building conservation, energy efficiency and users’ comfort. A thermal analysis, an energy retrofit design, a test on a pilot site, a comparison between before and after, are the tools that have been used to achieve this objective. Results provide some operational indications to merge conservation and sustainability in a 20th century heritage building.

    Bostäder på vatten i nordliga breddgrader: Möjligheten med etablering av vattenytan i form av flytande bostäder i subarktiskt klimat2017Independent thesis Advanced level (professional degree), 20 poäng / 30 hpOppgave
    Abstract [en]

    Due to the continued advancing of the building industry and the growing number of housing shortages, building on floating components has become an alternative to that on solid land or coastal areas that are geotechnically unsuitable for filling. This can even be done using portable and movable homes. The work is written for Aquashell and the study will describe the possibility of establishing homes on the water surface in Luleå using given floating components. By using suitable building materials and energy supply methods, the building is adapted to Luleå’s sub-arctic climate.

     

    The aim of the work is to design flexible housing which is portable and movable that enables settling on the water surface in colder climates in northern latitudes by the use of suitable materials and building modules.

     

    Firstly, a literature study was conducted on the subject together with studies in the form of interviews and location visits. Then a program was created with requirements for the building.

    After that a design proposal was made containing appropriate material choices which were then chosen to be visualized in Luleå’s Norra Hamn as a possible residential area.

     

    The floating homes are adapted to the climate and designed with respect to the surrounding environment in order to optimally take advantage of the scenic views in the area.

     

    The hope of the work is to demonstrate the possibility for housing on water by use of floating buildings even in sub-arctic climates. The work can also provide a potential solution in response to the ever-increasing shortage of housing.

    Steel slags from high-alloyed tool steel production were used in a full scale cover construction of a municipal solid waste (MSW) landfill. In order to study the long-term stability of the steel slags within the final cover, a laboratory experiment was performed. The effect on the ageing process, due to i.e. carbonation, exerted by five different factors resembling both the material characteristics and the environmental conditions is investigated. Leaching behaviour, acid neutralization capacity and mineralogy (evaluated by means of X-ray diffraction, XRD, and thermogravimetry/differential thermal analysis, TG/DTA) are tested after different periods of ageing under different conditions.Samples aged for 3 and 10 months were evaluated in this paper. Multivariate data analysis was used for data evaluation. The results indicate that among the investigated factors, ageing time and carbon dioxide content of the atmosphere were able to exert the most relevant effect. However, further investigations are required in order to clarify the role of the temperature.

    The recent state of the climate: Driving components of cloud-type variability2011Inngår i: Journal of Geophysical Research, ISSN 0148-0227, E-ISSN 2156-2202, Vol. 116, nr 11Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    To reduce the Earth's radiation budget uncertainty related to cloud types' changes, and better understand the climate constraints resulting from long-term clouds' variability, frequent and finer (than actually existing) observations are necessary. This is one of the aims of future satellite programs such as the Global Change Observation Mission-Climate (GCOM-C) satellite, to be launched by the Japan Aerospace Exploration Agency (JAXA). To facilitate the transition from past to future observations, the actual state of climate variables (e.g., cloud types) needs to be evaluated. This evaluation is attempted in the present work with the analysis of long-term cloud types' distribution and amounts. The data set used for this study is 25 years (1982-2006) of global daytime cloud properties observed by the National Oceanic and Atmospheric Administration- Advanced Very-High-Resolution Radiometer (NOAA-AVHRR) satellites sensors. Though various calibrations have been applied on NOAA-AVHRR data, the effects of the orbit drift experienced by these satellites need to be corrected. A signal processing decomposition method allowing the filtering of the cloud types' amount trend affected by the orbit drift is used to perform the necessary corrections. The results obtained show a quantifiable improvement of the cloud amount estimation and trends of the individual NOAA satellites initial observations, at the global and regional scales. The corrected global cloud amount shows a slight decrease in its linear trend. The driving factors of this trend are the decrease in mid and low clouds overwhelming the increase in high clouds (+0.04% cloud amount/yr). A comparison with other cloud climatology studies such as the International Cloud Satellite Climatology Project (ISCCP) data set shows that the global cloud decrease noticed in NOAA-AVHRR's data is smaller. And, contrary to the NOAA-AVHRR's data, the driving force of the ISCCP linear trend is a sharp decrease in low clouds (-0.20% cloud amount/yr).

    Global changes require renewed strategies. Do planners need new approaches or better understanding of their original role?2012Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Many stress that the role of planners will change under the new global situation. But what is the ’old role’ of planners which is expected to change? And will the ’new role’ be truly different from this ’old role’? The key messages of Torremolinos Charter, Agenda 21, New Charter of Athens, Territorial Agenda and other documents concentrate around few repeating concepts: complexity, balance, integration, inter-disciplinarity, cooperation, participation, education, involvement of politics, long-term orientation, creativity and strategy. Should planners change these ideals?One of the most frequent and influential words today is strategy. Even though strategy can be defined in many ways and there are many different forms of strategic planning around the world, its original meaning often remains hidden. There is no doubt that concept of strategy has a military background. Therefore, this article focuses on two main topics. First, it presents the five ancient principles for victory which can be transferred into the five principles for balanced development of territories as Continuity, Sustainability, Context, Leaders and Conditions for implementation. Second, it seeks interconnections between these principles and the role of strategic spatial planners. It discusses the role of planners particularly in connection to two principles: Leaders and Context. Since strategic spatial planners deal with coordination of expert teams having relevant influence on development processes, they belong to the principle of Leaders. Since they have all the relevant data, analyses and expertise, their role is to be honest while evaluating the situation and unmasking the real Context to others. Dishonesty, misinterpretations and preference of politics to professional esteem inevitably lead to wrong decisions.Accepting this premise, education of planners needs revision in two basic points. First, is should increase abilities to identify context of time, place and causality. Instead of making a ’list of facts’, the context should be measured and calculated to be as objective as possible. Second, the education should increase soft inter-personal skills to be able to handle leadership, present the context, negotiate the reasonable further steps, lead multi-professional teams, manage conflicts and self-develop. Being first-line leader is equally or even more important than being planning expert.Of course, new discourses and practices influencing methods, tools and performance in spatial development are needed. However, the new global situation calls for rediscovering and coming back to the original core role of planners: honest, brave and responsible expertise. The article presents an anonymous case study of how this ’new role’ changed the planned development project.

    Reframing planning theory in terms of five categories of questions2016Inngår i: Planning Theory, ISSN 1473-0952, E-ISSN 1741-3052, Vol. 15, nr 2, s. 145-161Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This article investigates how planning is influenced by five categories of questions (what, who, when/where, how and why) and the interactions between them. Planning theories differ in their answers to these questions but all of them are primarily built around an assumed connection between the questions of ‘what’ and ‘how’. This orthodox assumption of a ‘what-how’ connection is shown to be responsible for the failure of planning theories in practice and their inability to address issues of power. The article illustrates that both ends and means (‘what’ and ‘how’) are predefined by answers to three fundamental questions (‘who’, ‘when/where’ and ‘why’) and that there is no direct connection between ‘what’ and ‘how’ in practice.

    Strategic governance and planning as fractal2012Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Some years ago I experienced a project aiming to develop strategic documents in a city which was considered progressive. The project following communicative planning practice was considered successful and yet the documents weren’t implemented. My observations about discrepancies between planning and overall results clustered around few categories: continuity/consistency, aims, leaders and context/conditions. Since my observations were based on intuition rather than empirical data, I compared them with findings in Flyvbjerg’s influential book Rationality and Power (1998) offering 15 years of evidence. The categories were approved; moreover, the book uncovered some interactions and inter-dependencies between them which were not in line with communicative planning theory. Looking for explanation for my results, I consulted Chinese strategist Sun Tzu offering probably the most comprehensive understanding of forces hidden behind success or failure of decisions and activities. Interpretations of his manuscript (e.g. Sawyer, 1996; Lord, 2000; Yuen, 2008) reveal few universal principles applicable in governance and planning. I have this hypothesis: Strategic governance is a fractal having a self-repeating pattern which might help to understand complexity of cities. This pattern is qualitative, remaining the above key categories and their interactions. However, this hypothesis cannot be proved by empirical data at this stage. Therefore, this article sketches strategic governance as a fractal based on my own experience and illustrates its projection into planning. It shows how the hypothesis could bridge an increasing contrast between complexity of governance and simplicity of concepts required by communicative planning involving non-professional stakeholders and distributed decision-making practice.

    Improvements in addressing climate factors in urban planning and design2012Licentiatavhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Urban settlements located in subarctic regions have particular characteristics due to their climate. Climate and weather conditions influence people’s attendance in public spaces, their travel habits and recreational activities. In the subarctic regions, this influence is more visible due to greater seasonal differences. Urban design that deals with the generation and change of urban form can influence the impact of climate factors. Such interventions can be especially influential in the subarctic regions.This thesis focuses on addressing climate factors in urban design and transportation in the subarctic regions of Sweden. On one hand, it focuses on problems of incorporating climate factors into urban design, and on the other hand, it investigates travel patterns in relation to subarctic climate. The problems of urban design in subarctic regions were investigated by conducting a literature review and interviews with the planners from some of the Swedish northern municipalities. To study travel patterns in relation to cold climate, two travel surveys were conducted in Kiruna, a town located in the Northern Sweden. These issues are analysed and discussed in a covering essay and three attached papers. The interviews with planners show that climate considerations have a low impact on urban planning practices in these regions. The absence of a positive attitude towards cold climate, lack of knowledge and analytical techniques to be used in design, and weak relation between knowledge of climate factors and urban design practice are some of the major problems. Further, the interviews highlighted that dealing with snow in urban spaces (snow removal, better use of snow) is a crucial issue for these municipalities. The travel surveys in Kiruna demonstrated that car trips made a large proportion of all trips made in Kiruna while a very small part of trips were made by bicycle and public transport. The proportions of trips made by different transport modes (modal share) did not vary significantly in accordance to seasonal change, except in the share of bicycle trips, which dropped sharply during winter. Slipperiness, very low temperature, and wind have been the most negatively perceived climate factors when walking and cycling. Sunlight has been perceived positively. The distance travelled was shown to be correlated with the distance to the work place, but independent of the distance of the neighbourhood to the centre of Kiruna. Based on the analyses, improvements are suggested in three areas: institutions, design, and research. Institutional issues focus on how climate factors are handled in the municipal planning system. There is need for attitude shift, legitimacy and defining clearer goals in comprehensive plans. Design calls for active using of climate analysis and considering winter maintenance in developing design schemes. Research refers to collaborations between urban designers and experts from other fields, e.g. urban climatology, to develop knowledge applicable in planning and design.The potential of urban form in improving conditions for walking and cycling is significant. However, urban form seems to have limited potential for reducing the number of car trips in Kiruna with respect to long severe winters and current work distribution. The limitations of physical measures in affecting travel patterns can be partly improved by soft policy measures.

    Outdoor Comfort in Cold Climates: Integrating Microclimate Factors in Urban Design2015Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Designing urban spaces that provide outdoor comfort is an important but challenging goal in subarctic climates. An approach to urban design that is sensitive to subarctic climatic conditions is essential, but this requires effective incorporation of urban climate knowledge into urban design, which presently is impeded by several barriers. The aim of this thesis is to contribute to the knowledge of climate-sensitive urban design with a focus on outdoor comfort in cold climates. This thesis consists of a cover essay and three papers, which together address three questions: (1) What are the barriers to integrating climate factors into urban design in subarctic climates? (2) How do urban design practitioners address outdoor comfort in design process? (3) How can wind and solar considerations be integrated into the design of urban spaces? In accordance with the broad scope and interdisciplinary nature of this research, a mixed method approach was adopted, including a literature review, two interview-based studies and microclimate analysis of an urban design proposal.The study objectives were pursued in three stages corresponding to the research questions. The first stage consisted of interviews with local planners, which aimed to identify key barriers hindering the incorporation of climatic factors in urban planning in subarctic regions. Key findings include the identification of barriers related to design based, attitudinal, organisational, conceptual and technical issues. The design based issues relate to contextual difficulties for comfort design in cold climates, namely snow and low sun elevation. Attitudinal and organisational barriers include the neglect of opportunities for and challenges associated with urban liveability in cold climates, failure to exploit local knowledge and lack of engagement among local planners and politicians. Conceptual barriers relate to a lack of climate knowledge among practitioners and technical barriers relate to methods and the principles to be used in design, particularly wind comfort and snow in urban environments. The second stage centred on urban design practice, by investigating the role of comfort in the development of an urban design project in a subarctic climate. The findings of this stage showed that urban design practitioners predominantly rely on simple climate design principles and rarely use analytical tools in design. In terms of knowledge sources for urban designers, existing urban environments, work by other architects, the architects’ own experience and everyday life experiences are influential sources of understanding and inspiration. In the third stage a method to integrate outdoor comfort assessment into design is outlined and applied on a case study in a subarctic climate. The method encompasses wind comfort analysis and microclimate assessment based on solar access and wind velocity. It produces two types of result: quantitative and visual. The quantitative results include area ratios of different combinations of wind and solar conditions. Visual results are maps showing the spatial distributions of different microclimate combinations in a studied urban space, either proposed or existing. The method has proved useful for assessing relative differences in thermal comfort.Study stages highlight issues that are crucial for improving environmental comfort in subarctic climates: (1) provision of sheltering from the wind 2) maximising solar access and, (3) managing snow in the outdoor environment. In addressing these urban design issues, experimental design based research has the potential for creating and testing new design concepts. Practitioners’ reliance on simple climate design principles is also discussed. This research highlights that a more balanced application of climate design principles and analytical methods for addressing microclimate issues is required. Suggestions are also proposed to create a shift in the way outdoor comfort is addressed in practice, including clear goal definition, theory building and improving communications between research and practice.Key words: urban design, urban microclimate, outdoor comfort, subarctic climate, climate-sensitive, Kiruna

    Microclimate assessment method for urban design: A case study in subarctic climate2018Inngår i: Urban Design International, ISSN 1357-5317, E-ISSN 1468-4519, Vol. 23, nr 2, s. 116-131Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Interest in climate-sensitive urban design has grown in recent decades. Nevertheless, there are various difficulties associated with such an approach. One of these is the lack of simple comfort assessment tools. This paper presents a method for microclimate assessment that is composed of a wind comfort analysis and a microclimate assessment based on measuring a combination of solar access and wind velocity. The study includes analysis of a proposed urban project situated in Kiruna, a Swedish town located in the subarctic region of the country. The results from the simulations were then overlaid to produce combined microclimate maps for three specific dates: winter solstice, spring equinox and summer solstice. The maps illustrate relative microclimate differences between areas in the proposed project based on combinations of wind/lee and sun/shadow conditions. The outcomes showed that only a small proportion of the area studied had favourable microclimate conditions at the winter solstice and spring equinox. The thermal comfort Index OUT_SET* was calculated for the summer solstice in the study area. Comparisons between the spatial distribution of OUT_SET* values and the microclimate assessment map showed a large degree of correlation. The method is intended to be a simple and representative evaluation of microclimate

    The problems of addressing microclimate factors in urban planning of the subarctic regions2015Inngår i: Environment and Planning, B: Planning and Design, ISSN 0265-8135, E-ISSN 1472-3417, Vol. 42, nr 3, s. 415-430Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Urban life in the towns of the subarctic regions is affected by the severity of the local climate, which must be taken into account in urban planning. Previous studies show that the use of climate knowledge in urban planning is hindered by different constraints. In this study we focus specifically on the problems of incorporating microclimate factors into the urban planning practices in northern Sweden. We rely on a literature study and focus on interviews as our study methods. Some of the major problems identified are the lack of design knowledge relevant to a cold climate, lack of user-friendly tools to analyze microclimate, overlooking the potential uses of local climate, and lack of support from politicians. The problems related to knowledge development and the lack of tools for microclimate analysis are discussed further. In terms of knowledge issues, the planners’ awareness of climate objectives achievable at different planning scales needs to be improved. There should be further research into the effect of urban form on the use of snow and on snow-removal activities. Tools for microclimate analysis should become more user friendly for planners. More importantly, planners need methods that combine different microclimate analyses and offer a complete assessment of a given design scheme.

    Energisystemet är också en fråga om planutformning: teoretiska och empiriska studier av energisystemets rumsliga artefakter i fysisk planering2005Licentiatavhandling, monografi (Annet vitenskapelig)
    Abstract [sv]

    Det svenska energisystemet är under omställning för att på sikt låta förnybar energi svara för hela energitillförseln. Med detta följer fler anläggningar och en större diversitet mellan olika energislag. Kommunernas roll i detta är uppenbar. Inte minst i den fysiska planeringen som anger riktlinjer för samtida och framtida användning av mark och vatten. Den lokala planeringen har två huvudsakliga möjligheter att uppmärksamma energisystemets förändring. Det ena är att påverka omställningen genom att hantera produktion, distribution och användning av förnybara energikällor. Det andra är att uppmärksamma energisystemets påverkan på människa, mark och vatten. De energikällor som avses ersättas är mycket yteffektiva, det vill säga de har ett litet yt- och volymbehov i relation till producerad mängd el (företrädesvis). De förnybara energikällorna däremot har, i relation, en låg grad av yteffektivitet vilket innebär att det framtida energisystemet i flera fall kan komma att avsevärt prägla den lokala mark- och vattenanvändningen. Energisystemet är och har traditionellt setts som ett tekniskt, ekonomiskt, ekologiskt och på senare tid också som ett sociotekniskt infrastruktursystem. Men för att hantera förändrade rumsliga förutsättningar för energisystemet i den fysiska planeringen så konstrueras i avhandlingen ett synsätt där energisystemet ses som ett rumsligt infrastruktursystem. Dess delar, rumsliga artefakter, beskrivs som, och kategoriseras, utifrån indelningen av anläggningar, nätverk och brukare. För att studera hur energisystemet hanteras som ett rumsligt system genomfördes två empiriska studier, en deskriptiv och en explorativ fallstudie. De avser att belysa den befintliga och den möjliga planeringsberedskapen för energisystemet i översiktsplanen (ÖP), respektive i en specifik planeringsuppgift. Den andra studien fokuserade på hur energisystemet hanteras om en metodik för planutformningsprocessen används. Metodiken har en huvudsaklig rationell struktur, men med deliberativa ansatser. De empiriska studierna genomfördes för sex olika kommuner fördelade på två län, ett i norra och ett i södra Sverige. Resultaten visar generellt att det är storskaliga anläggningar och stor- och medelstora nätverk som ur ett rumsligt perspektiv är integrerade i kommunernas ÖP. Det handlar främst om anläggningar och nätverk som är av nationellt intresse för elproduktion samt fjärrvärmeverk och utbyggnad av fjärrvärmenät för lokal uppvärmning. Den geografiskt lägesbundna informationen är dock i samtliga fall så pass övergripande redovisad att det är svårt att genomföra någon bedömning av den befintliga och framtida påverkan på människa, mark och vatten. Mina slutsatser av arbetet med en rationell metodik för planutformningsprocessen är lika de som kommer av studien av ÖP. Detta kan sammanfattas som att metodiken inte medför att energisystemets rumsliga artefakter blir automatiskt integrerade i den fysiska planeringen. Den samlande diskussionen utifrån de empiriska resultaten antyder att energifrågor på lokal nivå framför allt är fokuserad på bebyggelsens energianvändning och -hushållning och inte så mycket på energisystemets sammansättning av egna rumsliga artefakter. Diskussionen resonerar också kring det att energi inte ses som ett rumsligt system i planeringen, utan oftare som ett tekniskt, ekonomiskt eller ekologiskt system att ta hänsyn till i planutformningen. Dessutom belyser diskussionen att energi till stor del är en fråga av nationellt sektoriellt intresse som kan bli överordnat en tydlig lokal anknytning mellan fysisk planering och energisystemets utformning.

    Rumslig legitimitet: när hållbar utveckling medvetandegörs2010Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    The political ambition for sustainable development is dependent on new attitudes and behaviors, as well as new physical environments. Sustainable development has, therefore, become increasingly important to analyze and describe within the fields of planning, urban design, and architecture to contribute to a positive attitude and to gain democratic approval throughout society. Sustainable development was explored through three studies of sustainable energy facilities; looking at space, place, and architectural design.In the first study planning and energy systems (production and distribution facilities) was in focus. This study dealt with the current practice of energy decisions based purely on political will in comparison to the effects on physical environment. The study attempts to illustrate how truly sustainable energy systems are dependent upon ties to space and place within the planning process. This was studied empirically on six comprehensive municipal plans. In these examples large infrastructure policies are emphasized over place-based energy planning, leading to non-sustainable growth. A connection between planning and the spatial placement of future facilities seems to be central to sustainable development. The second study dealt with urban design and the specific placement of energy facilities in local communities. This study indicated that facility placement in the public realm affects public attitudes. Spatial analysis was empirically used to study the location, position, and visual presence of distribution and production facilities in three Swedish communities and all three communities had well-integrated and visible energy facilities. According to the space syntax analysis certain facilities had more potential than others to develop into positive sustainable development icons. This finding further emphasizes that the potential to create awareness for sustainable development is place specific. The third study dealt with the architectural design of specific energy facilities. A theoretical review of previous research showed that the perception of sustainable development does not coincide with the individual experience of a specific representation of sustainable energy. The perception of sustainable energy systems was more positive than the reality experienced in the physical environment. This dissonance suggests that architectural design must play an integral role in the development of energy systems in order for them to be truly sustainable. In an empirical study individuals experiences of an architecturally designed power line compared to their previous attitude towards power lines. The results highlighted the potential to reverse negative associations of energy facilities by aesthetic and place-specific architectural design. A positive perception of sustainable development might, therefore, correspond with a compelling experience and not necessarily with long held attitudes.The theoretical and empirical results presented can be described by the term spatial legitimacy. This term explains the ability of the planning, urban design, and architecture fields to rearticulate physical form and function within a specific cultural context, thus allowing actual experience to correspond with held preconceptions. How communities design affects how communities plan and vice versa. Spatial legitimacy underscores the central connection between placement and architectural design in personal experience. The fields of planning, urban design and architecture have the potential and responsibility to further the field of sustainable development by helping us understand that design is as important to individual response and collective perception as is technology.
