- This study aimed at identifying passive design features through literature study that can be incorporated in residential buildings of Dhaka to make them energy efficient. The study also aimed at identifying changes in the design process that can affect energy efficiency in residential buildings. It has analyzed the present electric energy use for cooling and lighting typical residential buildings of upper middle income households in Dhaka through a case study conducted in Dhaka. It has also calculated the possible energy savings by adopting certain energy efficient features in the case study building. The findings from this study indicate that doubling the thickness of external walls on east and west of the building, use of hollow clay tiles instead of weathering course for roofs and use of appropriate horizontal overhang ratios for all four orientations can reduce the cooling load of the case study building by 64% and thus reduce the total energy use of the building by 26%. Finally, it can be concluded that the process of designing energy efficient residential buildings is not a 'one-man's show'. Architects, developers, interior designers and clients are the other actors who can bring a change in the design practice.

Ingår i: Journal of Transdisciplinary Environmental Studies. - 1602-2297. ; 7:2, s. 1-12

Tidskriftsartikel (refereegranskat)abstract
- Critics claim that neither results from sustainable housing demonstration projects nortools for the environmental impact assessment of buildings are used in mainstream housing practice.Th is raises the question of how research-based knowledge for energy effi ciency and environmentalsustainability in the built environment could be transferred to practice in a better way. In this articlewe propose a model to address this problem by combining refl ective research and “green engineering”.Th e model was developed through applying action research theory on generalized fi ndings ofempirical studies by diff erent researchers. Th e model is called Action Research for EnvironmentallySustainable Housing (ARESH). In this kind of research it is permissible to be openly normativeand to strive for change, but not to neglect critical refl ection. To achieve this, the researcher has toco-operate closely with co-researchers such as residents and housing managers, and, furthermore, tobalance between taking the roles of researcher, team member and teacher/preacher. On the positiveside, the model permits dissemination of information targeted at researchers as well as practitioners,and also “leaves behind” practical knowledge with the co-researchers after the project properhas ended.

Environmental Research as a Tool for Change : Theoretical and methodological implications from two case studies producing knowledge for environmentally sustainable housing
- 2006
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The theme of this thesis is environmental research as a tool for change. In the first part of the thesis a “Situation of Opportunity” is studied, i.e. a situation when the opportunities to reduce negative environmental impacts are larger than usual. The maintenance of a multi- family residential area, here called a Small Neighbourhood, is studied as a series of Situations of Opportunity. To explore the prerequisites for using maintenance as a Situation of Opportunity, two case studies were carried out and reported as a licentiate thesis. The first one on the rental area Idö-Våldö in Stockholm managed by the association Stockholms Kooperativa Bostadsförening (SKB), and the second one on Järven, a housing cooperative in Malmö that cooperates with the management organisation HSB Malmö. In the study the researcher developed long-term environmental strategies based on the planned maintenance of the areas. Besides exploring the prerequisites for using planned maintenance as a Situation of Opportunity, the intention was that the studies would initiate an environmental practice within the areas studied. Results indicated that maintenance, at least in principle, creates many possibilities for reducing negative environmental impacts and that it to some extent also can be used for creating a dialogue between residents and managers. However, the conditions for using maintenance in the cases studied were limited by low interest among the residents as well as the economical and organisational prerequisites of the cases. The studies did not initiate an environmental practice as intended. The reason for that might be the mentioned conditions, but it could also depend on the researcher’s limited knowledge on action-oriented and collaborative research. Thus, the second part of the thesis aims at developing a research methodology for such research. Based on empirical experiences from the Idö-Våldö and Järven-studies and a literature study, a methodology for action-oriented research for environmentally sustainable housing (ARESH) is outlined. It is proposed that methods of action research and of case study methodology could be applied in ARESH. However, there are several potential conflicts in ARESH. The researcher has for instance to judge if the study should be led in the first hand by participants or by researchers, or if it should be more oriented towards theory than practice. One conclusion is that a research methodology for such research needs to be further discussed and also further explored in practice. Since there are indications that a collaborative and action-oriented research is evolving in the field of environmental research, it is hoped that the findings of the thesis can contribute to a discussion on how to carry out research as a tool for change

How to “Renew a New City District”? : The citizens’ initiative HS2020 in Hammarby Sjöstad, Stockholm
- 2015
-
Konferensbidrag (refereegranskat)abstract
- How does the citizens’ initiative HS2020 realise its vision to ”Renew a New City District”? We followed the project organisation development between 2011-2014 and we applied strategic niche management and elements of actor network theory in order to assess barriers and opportunities. Hammarby Sjöstad is, since 1997, internationally renowned for its environmental ambitions. HS2020’s visions are an extension and further development of the latter, exploring potential contributions to sustainable urban development. HS2020 has been developing an actor network to implement projects in electric mobility, energy efficiency, culture and ICT. It is a unique but instructive initiative: if realised, its visions contribute profoundly to Swedish environmental quality objectives. It offers a little explored approach to city district management, between construction and refurbishment. Its potential contribution to sustainable urban development makes it important to explore and fine-tune the organisational elements for similar processes in other city districts.

Energy at your service : highlighting energy usage systems in the context of energy efficiency analysis
- 2011

Ingår i: Energy Efficiency. - : Springer Netherlands. - 1570-646X .- 1570-6478. ; 4:3, s. 355-369

Tidskriftsartikel (refereegranskat)abstract
- Increasing energy efficiency has for a long time been identified as an important means of mitigating climate change. However, the full potential for technical energy efficiency has seldom been fully exploited. The traditional approach in energy systems analysis and policy is still largely supply-orientated, i.e. focusing on the management of energy conversion, production and distribution, and final use of energy in the form of energy carriers. This paper contributes to previous discussions on how to highlight and explore the user side in the analysis of energy systems in an efficiency context. The energy usage systems approach, including end-use technologies and the production of service demanded by a human activity system, is used to promote a dynamic bottom-up perspective on energy. In determining the possible potential for change by increasing energy efficiency, the demand for energy should not be considered synonymous with the demand for neither energy carriers, nor the measurable service volumes (such as kilometres travelled, square metre conditioned space, etc.), without considering the sociocultural context in which the service is being used or called upon. In summary, the predominant paradigm dealing with the energy system as a technical system managing resources and providing energy carriers should thus be complemented with the view of a socio-technical system facilitating and/or managing the services.

Situations of opportunity for infrasystems : understanding and pursuing change towards environmental sustainability
- 2006
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Infrasystems are the large technical systems in society delivering water and electricity, making communications and transports possible, managing the gathering and treatment of refuse and sewage, and many other services. Infrasystems mean welfare, convenience and economic growth, but also considerable environmental impacts. The overall aim of this thesis is to contribute to the development of aspects and prerequisites of infrasystem change in a sustainable direction, by way of elaborating conceptual knowledge. The first main point of departure is the concept of infrasystem, and the related approach Large Technical Systems (LTS), primarily associated the field of history of technology. A key feature is to highlight a socio-technical systems perspective, rather than separating technology from social and institutional aspects. The second main point of departure is the change perspective Situations of Opportunity (SITOP), which is a draft theory developed within a research programme at the Royal Institute of Technology. SITOP set out from the notion that the possibility to implement changes in a sustainable direction is greater than average at certain moments in time. A situation of opportunity is associated with a prehistory, limiting the field of options for the actors utilising a formative moment. When SITOP, LTS and other related socio-technical perspectives are cross-fertilised some directions of where to look for future situations of opportunity for infrasystem change in a sustainable direction can be pointed out, e.g. in connection with certain problems or crises in the systems’ development. On the one hand different aspects on how to widen the field of options are discussed, e.g. to promote inter-sectorial actor networks, to identify system synergies and social innovations (paper 1-3), and to highlight services and functions rather than sectors and technology (paper 2). On the other hand, in order to approach the great changes needed in the context of sustainable development, the socio-technical regimes of today have to undergo major alterations, which probably presupposes new sets of actors and actor networks. A more moderate view however, is to seek positive synergies between everyday decision- and policy-making and the long-term striving for sustainable development. Issues often considered as necessities, e.g. renovations of old buildings, or building more roads to moderate congestion – ‘what must be done’ – should be combined with ‘what should be done’, e.g. implementing energy saving solutions in the built environment, or reducing society’s transport dependency. The array of conceivable combinations widens the field of options. The results also concern indirect effects of infrasystems, which might contribute to processes evaluating fields of options. Infrastructure investments affect activity patterns and the built environment (paper 4). Moreover infrasystems are associated with indirect energy use (paper 5). The conceptual views presented in this thesis are no immediate means, ready to be used in concrete infrasystem management, but can in the steps that follow primary policy-making support the process of finding out when to implement change, and moreover assessing plausible solutions. In other words – identify situations of opportunity and explore the field of options.

What if Sharing Were Part of the Citizen Initiative’s Vision? : Exploring Collaborative Consumption as implemented in Hammarby Sjöstad, Stockholm
- 2016
-
Konferensbidrag (refereegranskat)abstract
- “Renewing a New City” is the vision of citizen initiative HS2020, established in the ongoing brownfield development of Hammarby Sjöstad, Stockholm. Previous research indicates that there is a potential to further develop the Sjöstad, contributing to urban sustainable development. The Sjöstad is internationally renowned for its environmental profile and refurbishment lies in the far future. Therefore, this is of great general interest, although HS2020 in itself is totally unique.This paper presents a futures study exploring how HS2020 could work also with Collaborative Consumption, i.e. the residents’ sharing of goods, services, and space instead of owning it. It uses elements of explorative and normative scenario approaches to create future images of Hammarby Sjöstad in 2020. The images incorporate Collaborative Consumption in six established HS2020 sub-projects, on e.g. Energy Efficiency in Buildings, Interactive ICT, Recycling and Electric Vehicles. The images were generated through workshops with participants from the citizen initiative, with inputs from a literature review. In the HS2020 projects, sharing could take the form of Collaborative Lifestyles, Redistribution Markets or Product Service Systems. It could be open for anyone, restricted to members, or to residents within a building. These different groups could also initiate, own and maintain the sharing solution. Other potential actors are private companies, the municipality and non-profit organizations. Qualitative assessment indicates that Collaborative Consumption in the Sjöstad projects could reduce energy use and other environmental impacts. It could also help building local community, but realisation in itself also calls for elements of community and trust among participants.
