The German buildings sector is currently facing a double challenge: meeting emission reduction targets and providing affordable housing in rapidly growing cities. Living space per person has a major impact on household energy consumption and it has increased significantly in recent decades. New construction increases the demand for often energy-intensive building materials, and energy demand during the use phase of buildings is positively related to the size of the space. Optimising the allocation of living space therefore offers great potential for addressing both challenges. Sufficiency policies such as flat exchanges, a financial bonus for moving and the provision of moving advice aim to reduce the total floor area in the housing sector by using existing space more efficiently. However, the effectiveness of such measures is not yet fully understood. As the sufficiency approach relies heavily on individual choices, residents’ involvement, perception and acceptance are crucial for the success of such measures. An investigation in selected German housing companies shows that the potential of these measures is not fully exploited under the current political and social framework in Germany. Social acceptance, new norms and business models for landlords are needed for the effective use of these measures. Policy relevance How effective is the implementation of sufficiency measures for space utilisation in the German rental housing sector? The success factors and limiting barriers of the measures along with the acceptability and effectiveness of these measures are investigated by interviewing housing companies (some of them social housing providers) that have the potential to implement such policies in their housing stock. Improvements are needed in the social and technical infrastructure to increase the effectiveness of the measures. Raising awareness, rethinking communications and designing effective financial incentives are recommended to make the measures attractive to the public. Involving all stakeholders, keeping the issue on the political agenda and engaging in dialogue with policymakers are considered effective steps in the process of achieving space sufficiency in the housing sector.

Greenhouse gas (GHG) emissions from building activities are one of the most prominent contributors to the problem of global warming. Life-cycle assessment (LCA) is a widely used tool to investigate GHG emissions from buildings. However, there appears to be a lack of LCA studies on buildings in tropical climates, and especially in Thailand. This study aims to improve the understanding of GHG emissions from standard Thai residential buildings. LCA was conducted on five typical house designs in Thailand in order to determine potential mitigation strategies for future design of these houses. The amount of GHG emissions over the entire life-cycle of these detached houses was estimated, and the results were analysed with different viewpoints. The results indicate that emissions from the operational energies of detached houses in Thailand have the highest share of GHG emissions. Significant emissions also came from construction materials. Improvements to the building envelope and air-conditioner usage have high GHG mitigation potential in the operational stage of the buildings, while replacing cementitious and metallic materials with low-emissions alternatives can considerably reduce embodied emissions. Policy relevance The built environment has been a major source of GHG, but it also has high climate change-mitigation potential. This study explores mitigation strategies on the material and component levels of the most common building type in Thailand: detached houses. The results indicate the major sources of GHG emissions in the case study buildings, their correlation with building scale and other key design decisions. Potential mitigation solutions in different phases of the building life-cycle are identified.

Like other environmental concerns that affect human health, indoor air quality (IAQ) needs to be understood not only scientifically but also by the citizens who are affected by it. Six online focus groups sessions were conducted with people living in London who could be considered particularly vulnerable to air pollution exposure, namely older people, parents with young children and people with underlying health conditions. Each session involved an iterative process of group discussion, information provision and reflection/further discussion. A deductive thematic analysis guided by an environmental health literacy (EHL) lens was used to explore participants’ awareness of, and lived experience with, IAQ. The findings contribute to a better understanding of the EHL of vulnerable people, whilst also suggesting that learning more about IAQ (given the participants’ low level of prior knowledge) can be effective in increasing people’s willingness to make behavioural changes in indoor contexts. Several practical measures could be taken by various stakeholders to reduce residents’ exposure, especially those who have limited agency due to vulnerability (e.g. reduced mobility) or other personal circumstances (e.g. residing in a rental property). Policy relevance The findings from this study contribute to a better understanding of the EHL of vulnerable London residents, whilst also suggesting that information provision in the format of iterative discussion and group learning is effective at increasing people’s willingness and ability to make behavioural changes in indoor contexts. They also underscore the importance of providing occupants with information that not only encourages the use of ventilation systems but also includes awareness-raising materials concerning the sources and negative health impacts of poor IAQ. Furthermore, filtration technology should be made affordable which could require subsidies as part of national or regional air pollution policy; or new legislation to require air filtration systems in all new build or rented properties. Meanwhile, action from other stakeholders, notably landlords and housing authorities/associations, is also required to ensure good IAQ in rental properties, whilst tailored building design is needed to support people with reduced mobility.

With the growing urgency of addressing climate change it is increasingly important that decision makers at all levels are equipped to take efficient mitigation actions. This research evaluates the potential of four mitigation strategies to reduce greenhouse gas emissions from the building stock based on a case study, and these are further evaluated in terms of alignment with the remaining global emission budget and the planetary boundary for global warming. The results cover annual emissions from 2023 to 2050 across 18 impact categories, thus highlighting possible impact burden-shifting that may occur as a result of the mitigation strategies. The results show that decarbonisation of the electricity grid delivers a substantial reduction across impact categories. However, in absolute terms, this is counteracted by the increase in building stock. The results also show that current estimates for mitigation potentials are insufficient to comply with the remaining global emission budget. Thus, mitigation strategies should be even more ambitious: constructing 80% fewer new buildings and reducing operational energy demand by 80%. These findings highlight the urgency of taking multiple actions. The increase in demand for new buildings needs to be challenged. Practice relevance Present urban mitigation strategies are inadequate for meeting the stated GHG targets. To enable informed decisions it is important to quantify the effects of different strategies. Traditional life cycle assessments have static inventories and impacts can therefore not be temporarily differentiated and transparency cannot be provided on long-term potentials. This study suggests combining material flow analysis and life cycle assessment to enable integration of dynamic parameters into the life cycle inventory. This shows how the long-term effectiveness of different mitigation strategies can be evaluated. To ensure unintended burden-shifting does not occur, results cover annual emissions from 2023 to 2050 across 18 impact categories. Furthermore, this study showcases how strategies can be designed to align with global commitments such as those set by the Paris Agreement.

This sociotechnical investigation examines the use of ventilation systems in homes in London, UK. These homes were built with ventilation systems as described by guidance in the UK Building Regulations Approved Document F. These systems are assumed to provide adequate ventilation rates. However, previous measurements in these homes show that ventilation rates are inadequate. Using social practice theory as a framework to analyse the qualitative data, the intended use of the ventilation systems is compared to participants’ actual practices of manipulating the indoor air, revealing discrepancies between the two. Occupants had limited knowledge of indoor pollutants but were highly motivated to control and interact with the smells and air in their homes. They primarily used technologies that were not part of the planned system, because the latter’s functioning was opaque to occupants and not well connected to their other practices. The highlighted discrepancies in four case study homes between planned and actual ventilation system operation help to identify how future systems could be improved to ensure adequate ventilation rates and good indoor air quality in airtight homes. Policy relevance This research investigates the extent to which the intended operation of domestic ventilation systems set out in Approved Document F to the UK Building Regulations is accomplished in practice. The findings show that ventilation equipment is not used as intended. The research suggests a need for future guidance to more actively consider routes by which occupants can learn how to use and maintain their ventilation systems, and how to identify and remove indoor air pollution. There is a risk of continuing underventilation in homes unless efforts are made to ensure the systems are easily interpretable and robust to a reasonable range of internal conditions and social contexts.
这项社会技术调查研究了英国伦敦住宅通风系统的使用情况。这些住宅均按照英国建筑法规 F 批准文件中的指导意见安装了通风系统。然而，之前在这些住宅中进行的测量显示，通风率不足。利用社会实践理论作为定性数据分析的框架，将通风系统的预期用途与参与者操纵室内空气的实际做法进行比较，发现两者之间存在差异。居住者对室内污染物的了解有限，但对控制家中的气味和空气并与之互动的积极性很高。他们主要使用不属于规划系统的技术，因为后者的功能对居住者来说是不透明的，与他们的其他做法也没有很好的联系。本研究调查了英国建筑法规批准文件 F 中规定的家用通风系统的预期运行在多大程度上得以实现。研究结果表明，通风设备并未按预期使用。研究表明，未来的指南需要更积极地考虑居住者学习如何使用和维护通风系统，以及如何识别和消除室内空气污染的途径。如果不努力确保通风系统易于理解，并且能够适应各种合理的内部条件和社会环境，那么住宅中的通风量就有可能继续不足。

Globally, various frames of urban nature circulate, each emphasising particular challenges and natural solutions in the climate context. Yet which actors and dynamics shape their translation to the African context remains unclear. This paper explores the global-to-local translation process of frames through interventions funded by transnational actors, conceptualised as agents of policy transfer. Critical scholarship has observed that urban adaptation and resilience interventions in Africa are often characterised as technocratic and top-down approaches, hence it is vital to understand whether these are replicated through proliferating nature-based solutions (NBSs). The study of a resilience-building intervention in Lilongwe, Malawi, reveals that transnational actors play important roles by deploying frames of urban nature through funding projects. However, rather than involving a top-down imposition of particular solutions, this sets in motion dynamics: in the competition for resources that frames generate, various actor constellations of transnational actors, subnational governments and local NGOs reconfigure or relabel strategies and associated (nature-based) practices to suit global frames and the resources they generate. This shapes who is included or not, and what kinds of NBS are being developed, for and by whom. There is a risk that priorities of communities get lost in translation. Policy relevance Frames of urban nature shape global agendas but also matter locally in the design of programmes and projects. This study provides key insights of relevance for policymakers. First, external funding for climate and resilience is unpredictable and insufficient to address manifold urgent local priorities. It is important that actors at all levels strive to align resources to holistic strategies of local governments and do not impose certain visions for urban nature. For this to happen, and second, it is key that local governments and communities are empowered to create forms of nature that are built around diverse forms of local knowledge and expertise, to cater to values and priorities of the communities. Third, proponents of NBSs highlight their potential to address interlinked climate-, biodiversity- and society-related challenges. However, unless funding allocation puts emphasis on the interlinkage of goals, the potential for NBSs to reach multiple goals can get lost. Fourth, there is a need to disrupt the persisting scepticism concerning the feasibility of NBSs in informal settlements and forge collaborations that realise interventions closely linked to the priorities of disadvantaged groups in African cities, to leverage the power of nature for more just societies.

As European governments adopt new circular built environment policies to cope with the socio-ecological crisis, the need for evaluating such policies gains in urgency. Ex post evaluation is, however, difficult as these policies have not been in place long enough to have had significant effects. Nonetheless, ex ante policy evaluation may be possible by assessing policy coherence or the alignment and synergies of policy goals, instruments and implementation practices. This paper proposes a framework to analyse circular built environment policies. This framework is based on a combination of two existing analytical frameworks: circular city development and policy coherence analysis. The framework is tested for the case of a circular built environment in campus development at Delft University of Technology in the Netherlands, which is regarded as an urban development proxy. Policy documents and semi-structured interviews were analysed and coded. Results confirm previous findings about a prevailing focus on looping actions and indicates limited policy instrumentalisation across governance levels. Identified multilevel (in)coherence in circular city policy is pointed out as consequence of siloed-led and supply chain-based thinking and underdeveloped circular policy frameworks. Finally, the analytical benefits of circular city development and policy coherence frameworks are discussed. Policy relevance Circular economy policies are conceptually limited in delivering a more circular city and built environment. By proposing and testing a circular city policy coherence framework, this article reveals the limited effect of circular economy policies in coping with unsustainable urbanisation. Policymaking and implementation for circularity in the built environment require frameworks that embrace urban complexities instead of reductionist approaches seeing the built environment as a mere agglomeration of supply-chains. Policymakers may use the proposed circular city policy coherence framework as a tool for ex ante policy evaluation in diverse areas of urban development, and specifically for built environment interventions. The combination of both content- and process-based frameworks enables the identification of possible (in)coherence in current and future policy goals, instruments and implementation practices. This can improve policy in early stages of implementation and create more effective policy outputs and outcomes in the long term.

Ex post evaluation is, however, difficult as these policies have not been in place long enough to have had significant effects. Nonetheless, ex ante policy evaluation may be possible by assessing policy coherence or the alignment and synergies of policy goals, instruments and implementation practices. This paper proposes a framework to analyse circular built environment policies. This framework is based on a combination of two existing analytical frameworks: circular city development and policy coherence analysis. The framework is tested for the case of a circular built environment in campus development at Delft University of Technology in the Netherlands, which is regarded as an urban development proxy. Policy documents and semi-structured interviews were analysed and coded. Results confirm previous findings about a prevailing focus on looping actions and indicates limited policy instrumentalisation across governance levels.

This paper describes the development of a detailed plan to get the social housing stock of the Borough of Islington in London, UK, to net zero carbon emissions. This stock is very diverse in form, age and construction, and includes houses, flats and maisonettes. A total of 4500 buildings containing some 33,300 dwellings were modelled using the 3DStock method. Six packages of measures combining fabric improvements, heat pumps and photovoltaic installations were evaluated for each dwelling individually, in terms of costs, the impacts on gas and electricity use, and predicted cuts in carbon emissions. The rollout of measures between 2020 and 2030 was modelled with a specially developed scenario tool, allowing the user to set different criteria and priorities. Fabric measures on their own were shown to achieve only a 13% cut in gas use on average. Heat pumps are the key to displacing gas use. With all measures combined and taking account of the predicted decarbonisation of the electricity supply, it is only possible to achieve an overall 70% cut in emissions by 2030. Policy relevance The development of a detailed practical plan of action is described: an applied case study with the close engagement of the local authority—not a theoretical desk exercise. Each dwelling in Islington’s housing stock was examined and measured separately. The modelling did not rely on ‘archetypes’ as in many such studies. Realistic retrofit options were analysed in each case, using current cost data from practitioners. The same approach could be applied directly to other London boroughs, and for local authorities outside the capital, although different costs and other local factors would apply. For readers outside the UK, the methodology and tools could serve as exemplars. The findings about the respective contributions of heat pumps, solar photovoltaics and fabric measures, and the effects of different priorities in the rollout of retrofits, have relevance for policymaking more generally at local and national levels.

High-rise urban development has been controversial for its inability to foster cohesive and flourishing neighbourhoods. A social value perspective can help to better understand and evaluate how new developments in dense urban settings affect places and communities. While the link between wellbeing and social value is well-established in the literature, the question of how design can affect wellbeing and thus contribute to the social value of a development still requires further research and clarification. A better understanding of this relationship can assist architects, developers or consultants during the design process. A review is presented of relevant quantifiable aspects of building design that affect wellbeing in relation to the indoor environment and to social value specifically. A framework for fostering wellbeing is developed to test these aspects and evaluate the indoor environment performance. A case study building is used to analyse the relationship between building design and wellbeing. These lessons can be used to inform and evaluate building design during the design phases to complement the assessment of qualitative factors within a social value framework. Practice relevance This study identifies quantifiable aspects of the indoor environment affecting wellbeing in a high-rise development that can form part of a social value framework. This list of identified aspects provides a useful starting point for architects or consultants to assess designs. The indicators relate to quantifiable indoor environment aspects that can be directly controlled by building design and complement the broader concepts of wellbeing within a social value framework. The paper demonstrates how these aspects can be quantified in a case study mixed-use urban development as part of a post-occupancy evaluation. These quantifiable aspects could be integrated within digital tools to evaluate the building at the design stage to ensure that wellbeing is at the forefront of the project considerations.
