Looking back to move forwards: A social and cultural history of home heating (JUSTHEAT) : Interim findings from the first round of case studies
- 2023
-
Reports (other academic/artistic)abstract
- This short report is one of a series of outputs to flow from the international,interdisciplinary project ‘Looking back to move forwards: a social and cultural historyof home heating’ (JUSTHEAT), funded through the Collaboration of Humanities andSocial Sciences in Europe (CHANSE) initiative, which began in 2022 and runs until2025. Within this project, we aim to understand how major changes to home heatingand heating technology over the last 70 years have impacted our lives in diverse andoften profound ways and how these impacts are experienced differentially acrossplace, time, social groups and even between different members of the same household.Ultimately, we aim to distil learning from these historic accounts to promote a morehumane, user centred and just approach to the current transition from fossil fuelled tolow carbon heating systems across the UK and the EU. In pursuit of this, the projectemploys a combination of oral histories, archival research, a network of fine artists andinnovative approaches to bridge the chasm between policy makers designing lowcarbon heating transitions and the needs and expectations of the citizens they serve.

The Colour of Heating was Red: An overview of historical and policy narratives of domestic heating in Sweden, 1940 - present : JustHeat Strand II Report
- 2023
-
Reports (other academic/artistic)abstract
- This report has been written within the project Looking Back to Move Forward: a Social and Cultural History of Heating (JustHeat). The aim of the project is to unpack previous heating transitions at the home front since 1940 in order to enable more just and inclusive heating transitions in the future. The background is the notion that home heating transitions are deeply personal in the sense that they affect daily routines, division of labour between family members, and how we use our homes and energy alike. While there is much to be learned from intended as well as unintended effects of previous transitions, little effort has been put into understanding the lived experiences of technological changes in home heating, despite the uneven yet deep impacts they have had in society. This project will fill this gap by using oral histories to collect individual and collective experiences of home heating transitions that can complement and nuance dominating transition narratives.As a starting point, this report aims to tell the history of home heating in Sweden as it has been documented and told in policymaking and in the public debate. This will primarily be done by reviewing formative political documents and newspaper articles. In so doing, current transitions in domestic heating can be better understood in light of past transitions, and this report can be used as a formal narrative against which to confirm, complement, and contrast the oral histories. It is by no means a complete review of the events, arguments, and effects of home heating transitions since the 1940’s, but it captures some of the most important changes that – more or less, and for better or for worse – have affected people’s everyday lives.

Determining the Impact of High Residential Density on Indoor Environment, Energy Use, and Moisture Loads in Swedish Apartments-and Measures for Mitigation
- 2021

In: Sustainability. - : MDPI AG. - 2071-1050. ; 13:10
-
Journal article (peer-reviewed)abstract
- Recently, there has been an increase in apartments with a large number of inhabitants, i.e., high residential density. This is partly due to a housing shortage in general but also increased migration, particularly in suburbs of major cities. This paper specifies issues that might be caused by high residential density by investigating the technical parameters influenced in Swedish apartments that are likely to have high residential density. Interviews with 11 employees at housing companies were conducted to identify issues that might be caused by high residential density. Furthermore, simulations were conducted based on extreme conditions described in the interviews to determine the impact on the energy use, indoor environmental quality, and moisture loads. In addition, the impact of measures to mitigate the identified issues was determined. Measures such as demand-controlled ventilation, increase of a constant ventilation rate, and moisture buffering are shown to reduce the risk for thermal discomfort, mold growth, and diminished indoor air quality; while still achieving a lower energy use than in a normally occupied apartment. The results of this study can be used by authorities to formulate incentives and/or recommendations for housing owners to implement measures to ensure good indoor environmental quality for all, irrespective of residential density conditions.

Conference paper (peer-reviewed)abstract
- During the last few years, there has been an increased number of overcrowded apartments, due to increased migration but also housing shortage in general, particularly in the suburbs to major cities. The question is how the indoor environment in these apartments is affected by the high number of persons and how the problems related to high residential density can be overcome. This paper aims to specify the problem by investigating and analysing the technical parameters influenced by residential density in Swedish apartments built between 1965-1974. To map the situation, 11 interviews with employees at housing companies were conducted. Based on extreme conditions described in the interviews, simulations of the indoor climate and moisture risks at some vulnerable parts of constructions were made. Simulations were focused on moisture loads and CO2 concentrations as functions of residential density and ventilation rate. Finally, measures to combat problems associated to overcrowding are suggested. The aim is that the results should be used by authorities to formulate incentives and/or recommendations for housing companies to take actions to ensure a good indoor environment for all, irrespective of residential density conditions. © The Authors.

Sharing indoor space: stakeholders’ perspectives and energy metrics
- 2020
-
In: Buildings and Cities. - : Ubiquity Press, Ltd.. - 2632-6655. ; , s. 70-85
-
Journal article (peer-reviewed)abstract
- The sharing of indoor space can improve space and energy efficiency. The drivers and barriers to space-sharing initiatives are investigated from the perspectives of building users and building sector practitioners, based on interviews and a workshop. The role of energy performance metrics in promoting space efficiency is further analysed through a literature review. From the users’ perspective, space sharing can be understood through the interplay between tangible aspects (e.g. concrete benefits derived from sharing), organisational aspects (e.g. common decision processes and conflict resolution) and social aspects (e.g. group identity and consensus on appropriate behaviours). From the perspective of architects and property owners, shareable spaces require features such as flexibility and multifunctionality. The design of such spaces is limited by regulatory issues (e.g. building regulations poorly accommodate shared facilities) and business-related issues. One such issue is that building performance metrics normalised based on floor area do not incentivise the efficient use of space. A review of complementary metrics is provided, covering parameters such as number of users, layout, time of use, etc. Each metric serves a particular purpose; therefore, a set of complementary metrics can be used to support decisions at different phases of the building’s life cycle. Practice relevanceImproving space efficiency (e.g. by sharing indoor space) is a key strategy to meet simultaneously the future demand for facilities in cities and fulfil environmental objectives such as a reduction of climate change impact in the building sector. A clearer understanding of the specificities of space sharing is provided from the perspectives of building users and practitioners. This will assist practitioners to understand the needs of other stakeholders. Regulatory and business-related barriers to space-sharing initiatives are highlighted as a first step towards overcoming these barriers. Guidance is provided on complementary energy performance metrics appropriate for space efficiency. These metrics can be used to support various decisions during the different stages of a building’s life cycle.

Reducing the Impact of Bias in Oral Assessments
- 2023
-
In: LTH:s 12:e Pedagogiska Inspirationskonferens, 7 december 2023. - 2003-3761. ; 2023
-
Conference paper (other academic/artistic)abstract
- Oral assessment is an important method to evaluate the learning outcomes of scientific courses. However,there are certain limitations when oral assessment is applied.One of these limitations, which is not apparent in anonymous written exams, is the existence of biases which could lead to unfair (positive or negative) outcomes of the assessment. This could lead to decreased motivation and sense of belonging among minority student groups, potentially upholding or even increasing inequalities. The major issue with biases is that most of them are unconscious, meaning that it is very tough to mitigate. In this manuscript, we analyze the emergence and effect of expectancy-based bias through personal construct theory in order to find approaches to reduce the influence of bias in oral assessment. As such, we address biases existing before interaction with the student (stereotype), emerging from interaction with the student (halo bias), and how these can contribute to a biased idea of the student in the evaluator’s mind. We finally discuss how this can cause cognitive dissonance and biased assessment when student performance is not in line with the teacher's cognitive model of the student and propose solutions on how to deal with this to minimize bias in oral assessment.

Increased rent misspent? : How ownership matters for renovation and rent increases in rental housing in Sweden
- 2023
-
In: International journal of housing policy. - : Routledge. - 1949-1247 .- 1949-1255.
-
Journal article (peer-reviewed)abstract
- Renovations of the housing rental stock have become a political concern since they have been claimed to drive gentrification and affect tenants’ everyday lives as well as long-term housing conditions. Furthermore, new actors have entered the market, partly as a result of high supply on the international capital markets creating a flow of capital into market segments. This has led to a critique of private equity in the housing sector, and raised the question of the extent to which ownership of the rental stock matters for housing affordability. Yet there seems to be little systematic research on this topic. This study uses a unique dataset covering the entire rental housing stock in Sweden to address whether there are differences in renovation investments between different ownership groups. The purpose of this article is to increase understanding of how ownership affects renovation processes, and specifically to analyse to what extent, and how, private and public actors differ in renovation and rent setting decisions. Our results demonstrate that public housing companies raised rents less and renovated more, particularly in the lower-income segments of the multi-family building stock between 2014 and 2020. © 2023 The Author(s).

Balancing Social and Economic Sustainability in Renovation with an Affordable Option for Tenants? : A Pilot Study from Sweden
- 2022
-
In: Sustainability. - : MDPI AG. - 2071-1050. ; 14:7
-
Journal article (peer-reviewed)abstract
- A public housing company has applied a new renovation strategy, comprising no standards raising and thus rent-raising measures, in 20% of its apartments. Prior to renovation, the tenants were given the opportunity to choose renovation options involving different standards and costs after renovation. The purpose of the study is to follow up and give feedback on the renovation strategy. The aim was to evaluate implementation of the strategy in practice using a case study, in terms of the tenants’ opportunity to influence and the housing company’s profitability. To follow up, two methods were used: a survey of the tenants’ perception of choosing renovation options, and a financial assessment of the profitability based on the renovation cost and rent increase for different choice scenarios. The results from the survey show that the tenants appreciate being able to choose between different renovation options as it gives them the opportunity to decide on their housing costs and standard. With more than half of the tenants choosing the maintenance option involving a very low rent increase, the dividend yield will not be high enough to make the renovation profitable, but if only 20% had chosen the maintenance option, the dividend yield would be more feasible in the long run.
