Samlingsverk (redaktörskap) (övrigt vetenskapligt/konstnärligt)abstract
- One of the less known problems in settlement geography is the issue of so-called degraded and restituted towns. This lack of reconnaissance, however, is perhaps less the result of the towns’ scarcity than their specificity of being ‘awarded’ or ‘deprived of’ an urban label by means of strictly socio-political actions. Degraded and restituted towns, hence, are spatial units made ‘urban’ or ‘rural’ instantaneously, irrespective of their de facto state along what is widely considered a gradual path of (de)urbanization. Instead, they become compartmentalized into two constructed spatial categories that have survived the onslaught of material transformations and philosophical repositioning through different whims of time. While ‘rural’ and ‘urban’ are conceptual binaries that certainly need to be treated with caution, their cultural salience may cause tangible consequences within national administrative systems that abide by a formalized rural-urban distinction. This issue becomes particularly important for settlements that clearly transcend any imagined rural-urban divide, i.e. those, whose material and immaterial characteristics seem counterfactual to their assigned category. It is also crucial in formal practices designed to avert such counterfactualities, but whose ran-domness of approach more creates confusion than helps straighten out a historical concoction. Both processes, nonetheless, lend ‘urbanity’ and ‘rurality’ a resonance of objectivity, justifying their use as guides for a host of developmental endeavors, despite subverting a much more intricate reality. Degraded and restituted towns are direct derivatives of this. Drawing on the above-mentioned irreconcilabilities, the aim of this book is to present and scrutinize degraded and restituted towns through the example of Poland, where these towns occupy a special niche. For one, Poland, due to its chequered and variegated history, is home to a conspicuously large number of degraded (831) and restituted (236) towns; for another, Poland’s relentlessness of formalizing ‘urbanity’ as a category of statistical, political and cultural guidance has a direct bearing on the lives of the towns’ residents. Realizing the intricacy of degraded and restituted towns in the face of commonplace ru-ral-urban ideations, the editors and the 17 contributing Authors of this book have made an effort to capture the towns’ complexity with special foci on their shrouded origins, developmental specificity and incurred problems. Owing to the involvement of researchers from different scientific disciplines and subdisciplines, the undertaken project has helped elucidate the problem from multiple perspectives: spatial, social, demographic, economic, environmental, historical, architectural, cultural, legal and philosophical. Allocated into 17 chapters, not only have the presented interpretations allowed for a first interdisciplinary synthesis on the topic, but they also helped outline some prospective directions for future research. Moreover, collecting materials of such diversity into an amalgamated whole has helped identify specific discourses that enwrap the concept of “urbanity” when seen through its oscillations within formal contexts, and to which degraded and restituted towns serve as expendable game pieces. By combining knowledge arrived at through ontologically and epistemologically different approaches, the incremental contribution of this book as a whole could be summarized in two attainments: a) extending theoretical frameworks used to study degraded and restituted towns in terms of definition, conceptualization and assessing predispositions for future de-velopment on account of their spatial, legal, socio-economic and historical charac-teristics; b) initiating an anticipated discussion on a number of important and current topics re-lated to the practices of degradation and restitution that have not received adequate attention, e.g., the urbanity-vs.-rurality paradox, the changeability of human settlement forms vs. the consequences of rigid spatial categorizations; the role of various actors in shaping the socio-economic reality under the guise of an ossified binary; or identifying spatio-conceptual conflicts as future challenges for local, regional and national policy.

Ingår i: Archidoct Vol. 4. - 2309-0103. ; 4, s. 72-85

Tidskriftsartikel (refereegranskat)abstract
- What if we could predict trends, rising phenomena and future necessity in our build environment? If we could trace behaviors and forecast the needs for the future? If we had a tool for proposing architecture, that was able to point out potentialities and suggest additions, subtractions and modifications.If Architects had a tool to predict future demands, modification of the build environment could meet the changing behaviors and emerging phenomena in society. Research on existing building stock is reviewed in a context where prediction on complex indeterminate environments is possible. And an entirely new type of architectural tool is proposed, an algorithm for prediction.The algorithm, capable of making prediction in unstructured environments, is presented, and basis and idea of the algorithm is described in detail. The discussion focus on possible applications for this new tool, and the paradox of prediction is debated. Finally, improvements to the computational system are proposed.

Early Stage Architectural Design Practice Perspectives on Life Cycle Building Performance Assessment
- 2023
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Architectural practitioners can avoid negative social and environmental impacts of new construction by making decisions supported by impact quantification during design processes. However, most software tools developed for such quantification see little use in practice, especially in early design stages when decisions have the greatest influence. To identify ways for software developers to overcome this situation, a thorough literature meta-review of previously performed tool reviews was combined with interviews applying a practice lens. The first key finding is that a possible explanation for the low tool uptake in practice could be a missing practice perspective in previous tool development efforts. In a literature meta-review of publications on life cycle building performance tools identifying previously applied perspectives, most previous tool reviews were found to support tool development and selection, while disregarding how tools can be integrated in existing practices and design processes. As a proposed solution, a framework for defining software requirements using a practice perspective was developed. The second key finding is that a practice perspective could be applied during software development by implementing qualitative methodologies. Nine architectural practitioners in Sweden, Norway and France were interviewed using the interview to the double, a projective technique in which the interviewee is asked to describe their next workday in detail so that their tasks can be assumed by an imagined body double. The design activities described by the respondents were sequenced into user narratives which could serve as starting points for participatory software development processes within the architectural practice. The outcomes - a proposed framework for practice-centric software requirements, and a proposed methodology for collecting these requirements using a practice lens - indicate a research direction toward software development efforts which aligns with design process, architectural practice, and tool user needs. In the next stage of the research this direction will be pursued through application of the developed methodologies in participatory development case studies in early-stage architectural design practice.

- The paper describes a method and an approach to using sensor data, machine-learning and pattern recognition for proposing and guiding immediate modifications to the existing built environment. The proposed method; Induced Representation, consists of a few steps which we have identified as crucial for such an approach. The steps are A: data collection from the environment, B: machine cognition, learning, prediction, and, c: proposition, visualization, and embodied representations for quick implementation. In the paper we outline the factual and theoretical basis for this approach, and we present and discuss three experiments that each deal with the steps A, B and C.

Konferensbidrag (refereegranskat)abstract
- What are the effects and perceptions of increased installation of water metering and volumetric billing in residential areas in Sweden? An interview study was undertaken in a low-income suburb of Göteborg to explore residents’ experiences and opinions. Additionally, the interests of water and energy companies, social affairs committee, real estate owner and maintainer were investigated to contrast the added value of reduced water consumption. Stakeholders either benefit or are disadvantaged by the introduced system. Furthermore, the applied tariff structure fails to motivate all segments of the population to reduce water consumption, yet still inequitably burdens the most financially exposed groups.

Assessment and optimization of life cycle enrgy use in buildings
- 2018
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Buildings account for 40% of all energy use in European countries. The European Union (EU) therefore encourages member states to adopt Energy Efficiency Measures (EEMs) and implement energy-efficient practices during building design to minimize the energy use of buildings. However, recent studies have shown that energy-efficient buildings may not always outperform conventional buildings in terms of Life Cycle Energy (LCE) use. This is mainly due to the trade-off between embodied and operational energy, and a reliance on EEMs that reduce operational energy while sometimes increasing embodied energy and LCE use. To improve buildings’ environmental performance, the impact of different EEMs on buildings’ energy use needs to be assessed from a lifecycle perspective, and methods for identifying optimal combinations of EEMs that minimize LCE use should be developed. Ideally, these methods should be integrated with building information modelling (BIM) to enable seamless data exchange and to help Architecture, Engineering and Construction (AEC) practitioners make optimal design decisions relating to EEMs. The work presented in this thesis had two overall objectives: (1) to explore the scope for developing BIM-supported method(s) for assessing and optimizing the impact of EEMs on buildings’ LCE use during the design process, and (2) use the BIM-supported method(s) for exploring the impact of various EEMs that are implemented and modified during the building design process on the buildings’ LCE use.The work presented in this thesis is based on an exploratory research design involving iterative cycles of (1) problem identification, (2) method development, (3) method examination, and (4) theory suggestion. In step 1, problems were identified by conducting literature studies and workshops with AEC practitioners, and analyzing archival data. In step 2, prototyping was used to develop methods to overcome the identified problems. In step 3, the applicability of these methods (or prototypes) was tested in case studies on actual and hypothetical building projects. Three case studies were conducted – one dealing with a low energy dwelling located in Kiruna, Sweden; another dealing with a multifamily residential building in Uppsala, Sweden; and a third dealing with a hypothetical multifamily residential building in Stockholm, Sweden. In step 4, the results were compared to existing theories to strengthen existing knowledge and identify previously unrecognized findings.In relation to the first objective, the results obtained show that the factors and activities required to develop BIM-supported method(s) for assessing and optimizing the impact of EEMs on a building’s LCE use during the design phase are:• A database that stores external and building project data (e.g. BIM data) and links it to be used for assessment and optimization, providing access to the data whenever needed.• The development of interfaces using middleware applications to ensure interoperability and seamless automated exchange of information between BIM and other systems.• Predefined objects (i.e. building part and component recipes) that are stored in a database and linked to inventories and Environmental Product Declarations (EPDs) for the relevant materials, enabling assessment of the buildings’ embodied energy and LCE use.• The application of multi-objective optimization techniques (e.g. Pareto-based genetic algorithms) to identify optimal solution(s) for EEMs that minimize (optimize) the building’s LCE use.In relation to the second objective of the thesis, the results obtained indicate that:• EEMs that are implemented and modified during the detailed design phase have much less influence on the building’s LCE use than those implemented in the early design phase. Highly influential EEMs related to the early design phase which were tested herein were the building’s shape, orientation, Window to Wall Ratio (WWR), and the selection of materials used in the building envelope.• Generally, thickening roof insulation has a strong beneficial effect on LCE use for buildings in Sweden.• For buildings using energy sources with high primary energy factors, the most effective way to reduce LCE use may be to implement many EEMs that reduce operational energy use. However, this approach may be less helpful for buildings using greener energy sources because in such cases the embodied energy may have a greater effect on the final LCE use.• The embodied energies of materials in the same class can vary significantly between suppliers. Such differences in embodied energy can be identified by considering the suppliers’ EPDs, the energetic contributions due to their mode of transportation from the site of production, and the distance between the site of production and the construction site.• If the developed optimization approach is used to identify optimal combinations of EEMs in the early design phase, designers can freely choose from a wide range of building shapes without greatly affecting LCE use. However, without early phase optimization, designs that use different building shapes may exhibit significantly different LCE use values.The results provide both theoretical and practical contributions that may be useful to researchers and AEC practitioners seeking to develop BIM-supported design processes and to reduce buildings’ LCE use by adopting appropriate EEMs. The results also show that embodied energy can be a major component of a building’s LCE use if the building’s design relies heavily on EEMs designed solely to reduce operational energy use. Policy makers and governmental bodies are thus advised to update regulations and building codes to reflect the importance of embodied energy so as to minimize the LCE use of new and retrofitting building projects.
