Abstract Over the years housing associations in the Netherlands have sold a lot of terraced houses to individual homeowners. As a result housing associations often no longer own all houses in the same block of terraced houses. This situation of variable ownership, also referred to as mixed property, represents a challenge in itself when it comes to large scale energy renovation. The goal of this study was to explore the approaches that exist in practice for energy renovation of mixed property. Based on a series of interviews, followed by a collaborative meeting with the interviewees, we suggest that current approaches for energy renovation of mixed property mainly differ in two ways. First, approaches vary in terms of leadership. Is a single organization, for example the housing association, in charge of the energy renovation? Or is leadership spread among multiple stakeholders? And second, approaches vary in terms of pace. Is the energy renovation carried out in one big leap? Or is it carried out in multiple steps over a longer period of time? Based on these differences we present a four-quadrant model of energy renovation of mixed property.

This paper investigates how social outcomes from urban transport projects typically play out by reflecting on multi-scale spatial changes induced by projects over time, and the extent to which such changes meet varied interests in project outcomes. We use a multi-methods case study approach using two exemplars, a metro project in London and Seoul, which established extensive public transport networks to support urban growth. Our study highlighted that urban transport network expansion does not always enhance life opportunities for all due to intermediate and cumulative impacts of spatial changes induced by projects. Immediate benefits such as enhanced accessibility were often undermined by long-term consequences of incremental spatial changes at local scales. This study also indicated that differential patterns of spatial changes around nodes between centre and periphery could be attributed to multiple negative impacts on people living in the most deprived areas. To enhance social outcomes, we suggest an integrated approach to urban transport and spatial development that focuses on scale and temporal dimensions of spatial transformation enacted by projects. In conclusion, achieving sustainable and equitable effects from urban transport infrastructure requires careful examination of broader societal consequences of long-term spatial changes and locational contexts, especially function and socio-economic conditions.

Abstract This study aims to identify and categorise the sustainability concerns raised in retail planning policy discourse, using empirical data from Finland. In order to identify the concerns, we conducted a critical discourse analysis of the policy discourse presented in media from 1990 to 2015. The analysis was conducted chronologically in order to understand the evolution of the sustainability concerns and the changes in the policy debate. To categorise the concerns identified from the discourse, we developed a holistic sustainability framework based on previous literature. Our findings show that during 1990′s the concerns were mostly socio-economic, however, due to enforcement of sustainable development policies, the share of environmental concerns raised significantly in 2000s. The findings of our study reveal the problematics of the retail planning policy making and call for a more holistic understanding of the multidimensionality of the sustainability impacts of retail planning.

In cities of the Global South, socio-technical heterogeneity in electricity provision is a reality that has partially shifted debates to the diversity of arrangements beyond the grid. Building on the case of Kingston in Jamaica, this article focuses on the relationship between the grid and such heterogeneous configurations and considers how heterogeneity transforms existing power relations. By analyzing the different strategies that actors (the government, the electricity provider, different types of consumers) have developed to address different challenges (energy transition, non-technical losses, affordability, etc.), the article shows how this heterogeneity entails a political process that reshapes possibilities and constraints for governing, and being governed by, the electricity grid. This analysis suggests taking solidarity as a central dimension when considering how to govern heterogeneous configurations, including the relationships between consumers, types of socio-technical systems and neighborhoods.

AbstractAnalyzing the politics and policy implications in Brazil of attributing extreme weather events to climate change, we argue for greater place-based sensitivity in recommendations for how to frame extreme weather events relative to climate change. Identifying geographical limits of current recommendations to emphasize the climate role in such events, we explore Brazilian framings of the two tragic national disasters, as apparent in newspaper coverage of climate change. We find that a variety of contextual factors compel environmental leaders and scientists in Brazil to avoid and discourage highlighting the role of climate change in national extreme events. Against analysts’ general deficit-finding assumptions, we argue that the Brazilian framing tendency reflects sound strategic, socio-environmental reasoning, and discuss circumstances in which attributing such events to climate change—and, by extension, attribution science—can be ineffective for policy action on climate change and other socio-environmental issues in need of public pressure and preventive action. The case study has implications beyond Brazil by begging greater attention to policies and politics in particular places before assuming that attribution science and discursive emphasis on the climate role in extreme events are the most strategic means of achieving climate mitigation and disaster preparedness. Factors at play in Brazil might also structure extreme events attribution politics in other countries, not least some other countries of the global South.

AbstractBuildings are responsible for approximately 36% of carbon emissions in the European Union. Besides, gradual aging and a lack of adaptability and flexibility of buildings often lead to destructive interventions, resulting not only in higher costs but also in a large amount of construction and demolition waste (CDW). Recently, an innovative system (Ref. VEEP project) has been developed to recycle CDW for the manufacturing of energy‐efficient prefabricated concrete elements (PCE) for new building construction. By applying life cycle costing (LCC) and life cycle assessment (LCA), this study aimed to determine whether the use of VEEP PCE leads to lower carbon emission and lower associated costs over the life cycle of an exemplary four‐story residential building in the Netherlands than a business‐as‐usual (BAU) PCE scenario. This paper provides a case study on the alignment and/or integration of LCA and LCC in an independent and a combined manner (via monetization). This study examines how the internalization of carbon emission and discount rate will affect the final life cycle costs over a 40‐year life span. The simulation results show that the key to economic viability and environmental soundness of VEEP PCE is to reduce production cost and to optimize the thermal performance of the novel isolation material Aerogel; internalization of external cost monetarizes the environmental advantage thus slightly expands the cost advantage of low carbon options, but leads to larger uncertainty about the LCC result.

This research aims to develop a decision tree model for understanding actual gas consumption in residential buildings. Extending previous studies, this study examined to what extent four different type of factors, building characteristics, socio-demographics, psychological factors and household behaviour can explain actual gas consumption of Dutch households in 2017 and 2018. Data were collected from 601 households. A novel approach, a decision tree method, revealed that household gas consumption was related to building characteristics, socio-demographics, and psychological factors, while energy-related behaviour in households was not uniquely related to gas consumption. Specifically, house size, building age and residence type (building characteristics), household income and employment status (socio-demographics), and most notably egoistic values, hedonic values, environmental self-identity, perceived corporate environmental responsibility of the energy provider, and social norm (psychological factors) predicted total actual household gas consumption. These results illustrate that the novel integrated framework introduced in the paper yields a better understanding of actual household gas consumption. The results have important practical implications and suggest that it would be important to target these three type of factors in policy aimed to reduce household gas consumption.
