Abstract [en]

Residential energy consumption remains a significant driver of CO2 emissions in European buildings, demanding urgent action in the face of the climate crisis. While prevailing efforts have predominantly concentrated on enhancing energy efficiency and integrating renewable sources, addressing the climate urgency and resource constraints necessitates a paradigm shift towards sufficiency principles. Swedish statistics on Single-Family Houses (SFH) show that more than a third of households inhabit oversized spaces in aging buildings needing renovation. Sufficiency-oriented renovation strategies—optimizing, or reducing living areas per capita— present a promising avenue to achieve substantial energy reductions. This approach also opens the potential for space rentals, yielding combined energy and space efficiency advantages. In addition, the literature highlights reduced maintenance costs and potential urban housing crisis mitigation. However, practical implementation faces multiple obstacles.This paper investigates SFH owners' attitudes towards space-sufficiency interventions, focusing on living size preferences and identifying barriers and opportunities for sustainable housing. Through focus group sessions with SFH owners in November-December 2022, qualitative content analysis revealed that reducing living space per capita faces multifaceted challenges, despite potential benefits.These challenges encompass not only personal and psychological considerations but extend to economic, infrastructural, and policy barriers, including issues such as the potential breach of privacy, disruptions due to noise, dilemmas related to ownership and independency, disruptions to work-life dynamics, inadequate familiarity with sufficiency principles, and uncertainty imposed by space constraints. Strategic integration of sufficiency principles into energy-renovation policy alternatives necessitates a holistic approach that addresses these barriers, and some form of incentives may be needed to catalyze the adoption of sufficiency principles effectively.

Abstract [en]

Circularity in construction industry requires understanding of the complex system dynamics, which are affected by various building layers and societal systems. While the existing building stock offers opportunities to enable re-looping of construction and demolition waste, the assessment of building circularity performance is not straightforward, due to lack of standard database, methods, and tools. This may lead to subjective interpretations by practitioners who rely on lifecycle assessment (LCA) approach complemented with circularity indicators (C-indicators) to know the level of circularity (LOC) of building materials, components, and elements. Thus, these C-indicators requires careful evaluation of the current methodological approaches. The aim of this paper is to map and evaluate the nexus between assessment methodologies highlighting their strengths, limitations, and areas of improvement. In this study, a complementary approach of systematic literature review and design research concept was used to classify seven primary aspects covering 18 key performance indicators, that impact the system thinking approach of the renovation project. The critical analysis of ten distinguished C-indicators show conditional, beneficial and trade-off relationships between various indicators. At the same time, the dynamic aspect of re-looping the resources is missing in these indicators and sustainability is accounted by complementing lifecycle impacts rather than coupling them. Results of this review highlight substantial gaps in C-indicators applicability for renovation projects with emphasis to formulate a practical guidance to assess recirculation of materials throughout the value chain.

Abstract [en]

Uncontrolled open dumping and burning of municipal solid waste (MSW) has resulted in soil, water, and air pollution in many urban cities in India. Landfills are the most common cost-effective solution for MSW management in many developing countries like India. However, the identification of suitable landfill sites always remains a challenging task as it involves the selection of several environmental criteria set by the local authorities. The objective of this study is to identify the most potential landfill sites proposed by the Government in Bengaluru Metropolitan Region, Karnataka state, India using Geographic Information System enabled Analytical Hierarchy Process based multi-criteria evaluation technique. Several criteria and constraints as recommended by the local authorities along with the proximity to the solid waste processing plants are used to identify the potential landfill sites in the study region. The study identified three highly suitable sites (Neraluru, Gudhatti, Madivala) for landfills which are not only environmentally sustainable but also economically attractive as they are closer to the solid waste processing plants minimizing the transportation cost involved in the disposal of solid waste from the source to the final disposal sites in the study region.

Abstract [en]

The ageing building stock in the European Union (EU) is not adequately equipped to deal with the changing climate, posing a significant challenge for climate change mitigation and adaptation. This has driven governmental institutions and private firms to expedite their renovation efforts; integration of one-stop-shop (OSS) regimes for encouraging higher rates of renovation could stimulate the rate of renovation by up to 6% annually, the aimed rate for the 2030 Renovation Wave by the European Commission. While OSS solutions present a great opportunity for addressing the challenges posed by climate change by allowing older homes to become better prepared through climate-smart retrofitting, these solutions have had mixed results in the past. Given the urgency of the situation as predicted in various scenarios by the IPCC, it is imperative to assess the effectiveness of OSS solutions in accelerating the rate of renovation. This research aims to investigate how the digitalisation of aspects of the customer journey of an end user participating in an OSS home renovation platform can lead to overcoming challenges faced by previously implemented instances of it. 

To answer this question, first a systematic literature review of previous OSS schemes implemented in Europe, digital tools commonly applied for renovation, and state-of-the-art strategies and models to facilitate customer journeys were studied. Through the characterisation of these mechanisms, opportunities for the integration of digital tools were identified and suggested for each stage of the customer journey. It was found that through the utilisation of technologies such as application programming interfaces (API), for increased access and real-time updating; blockchain infrastructure for information transparency and symmetry, and urban building energy modelling for predictive assessment, some important pitfalls of OSS implementation can be addressed. This study is expected to contribute to the renovation sector, ultimately leading to improving buildings' adaptive capacity, which is critical for the EU's sustainable development objectives going forward.

Abstract [en]

The municipal solid waste (MSW) remains a great challenge in most cities of developing countries, as the majority of the generated waste is either not collected or is dumped in open uncontrolled non-engineered landfill sites, creating significant pollution due to the leakage of landfill leachate in the surrounding environment. In developing countries, a complete transition to a zero-landfill scenario is less likely to happen in the near future due to various socio-economic challenges. Therefore, the existing landfills in developing countries need holistic waste management thinking with more efforts on waste to energy conversions. This study highlights the challenges with existing MSW management practices of Curitiba, Brazil, and suggests some holistic and sustainable landfill management techniques. This is accomplished through the (i) identification of the suitable sites for setting up transfer stations (TSs), (ii) route optimization for MSW transportation, and (iii) analysis of the life expectancy of the existing landfill with waste valorization techniques for enhancing circularity of MSW of the city. The study has identified six potential TSs, making use of various geological criteria and constraints as suggested by the United States Environmental Protection Agency using GIS-based spatial analysis, which could save fuel cost of approximately 1.5 million Brazilian Real (BRL) per year for the solid waste transportation (from the source to the landfill site). This research has also made a value addition in this specific field with the preparation of a digitized road network map of the study region. Further, the sensitivity-based scenario analysis highlights that the lifespan of the existing landfill (until 2030) might be extended to 2058 if the city achieves the targeted recycling rate of 85% compared with the current rate of 23%. The results would be useful for policy-makers to adopt the crucial MSW scenario to achieve a circular economy in the waste management of the city of Curitiba.

Abstract [en]

Although Scandinavian countries, including Sweden, are relatively less vulnerable to climate change, Swedish residential dwellings specifically those constructed before the 1975s are likely to be impacted by current extreme weather events (EWE) such as urban heat islands (UHI). This EWE can worsen air quality, increase heat-related illnesses (particularly among vulnerable populations), and raise maintenance costs and energy demand for cooling in buildings.This study aimed to map UHI risk in Sweden's residential sector using a scenario-based analysis approach. Moderate Resolution Imaging Spectroradiometer (MODIS) Remote sensing (RS) imagery data (land surface temperature (LST)) and some statistical data (including the number of houses, building typologies, and characteristics) collected from the SCB (Statistics Sweden) and TABULA database are used. The overall UHI risk maps for Sweden are developed following the risk matrix approach, by weighting and aggregating the created maps for UHI hazard, building exposure, and vulnerability. Here, the geographical information system ArcGIS pro 3.1 was used to carry out the different spatial analysis tasks, including pre-processing of spatial data, developing required maps, and performing raster calculations.The outcomes reveal a range of areas posing risks, with most high-risk zones situated in the southern and southeastern regions. Moreover, there is a discernible impact of the UHI on most of the buildings across Sweden constructed prior to the 1960s. Nevertheless, for structures built between 1961 to 1975, only those in the southern regions display potential susceptibility to the UHI. Furthermore, the western areas exhibit a low UHI risk.Despite the limitation of data used, the findings of this study have practical implications, as they can help homeowners, renovation companies, and policymakers implement appropriate adaptation strategies. The approach used is comprehensive, easily applicable, scalable, and can be replicated anywhere, assisting in the development of climate-resilient buildings not only in Sweden but also in other regions.

Abstract [en]

The Sustainable Business Model Canvas (SBMC) offers a useful tool for business model design, as it manages to integrate all three dimensions of sustainability without distinguishing between three different layers (economic, environmental, and social). This paper presents the application of SBMC in a real study case of a one-stop-shop (OSS) for the renovation of single-family houses operating inKronoberg province in Sweden. The case is based on shifting from the current approach of the OSS, making interventions that will lead to the development of a "new" OSS which can reach the highest possible sustainability potential. A two-stage comprehensive assessment process for the "new" model is proposed, following a lifecycle perspective. The use of SBMC and the assessment process allows both existing and under-development OSSs to gain a better understanding of different alternatives regarding their business, and how these alternatives improve or weaken their existing business model. This work also proposes the steps that should be followed to assess the impact of potential intervention in the business model on the sustainability performance of an OSS. There is a need though to acquire relevant data to make a more detailed evaluation of the economic, environmental, and social burdens and benefits of an OSS. Such an evaluation will lead to more well-informed interpretations regarding the sustainability performance of different OSSs.

Abstract [en]

In Northern Europe, Single Family Housings (SFH) constitute a large share of the total building stock. In Sweden, more than 52% of the population lives in SFH. Most of these houses were built between 1960-80 and are currently needing renovation. Most of these houses are owned by older adults whose kids have moved away, and thus they live in housing over-dimensioned to their needs with a large share of energy consumption for space heating. Furthermore, these facilities are neither elderly-friendly nor energy-efficient, deeming major renovation.

 

This paper applies a case-study approach to explore options to better utilize and reduce the living area per capita through the generation of Additional Dwellings Unit (ADU) within the existing building stock owned by the elderly. The case study SFH owned by an elderly couple is located in Kronoberg Region, Sweden, and is a typical SFH built during the 1970s. We redesign and restructure the underused space to create an ADU that can be rented out, which in turn may economize the high investment costs of energy-efficient renovation. The energy efficiency renovation measures considered were improvement of the building's climate shell (envelope), extra insulation in the walls and attic, and better performance doors and windows. Energy simulations and life cycle cost assessment of the energy efficiency measures, and space redesign showed that it is possible to reduce energy use by 61% compared to the existing condition of the reference house and a payback time of 59% compared to the application of the energy measures alone. The proposed intervention is aligned with the aging in place strategy, tackling it from a space sufficiency perspective. The proposed intervention reduces the living space per resident by 40% and energy consumption per capita by 62% compared to just the energy renovation of the reference house while creating cash inflows that motivate the houseowner to uptake an energy renovation. The improved energy performance of the building may generate better indoor living conditions for a healthier life for the residents.

Abstract [en]

Sweden's shortage of affordable housing has been evolving into a major in recent years. A 2021 report by the Swedish National Board of Housing, Building, and Planning (Boverket) stated a need for 60,000 new homes by 2030. In addition, the Swedish building stock is responsible for 39% of the country's total energy consumption and 21% of its greenhouse gas emissions. Therefore, solutions to address the housing crisis should go hand in hand with the need for increased building retrofits to meet Sweden's 2045 energy and climate targets. In this context, re-densification of the existing building stock is a possible option. This study examines possible space- and energy-efficient options for densifying the housing supply in Sweden's existing single-family home (SFH) segment. Using a case study in Kronoberg, Sweden, occupied by an elderly household, options for converting the unused space into new additional dwelling units (ADUs) and reducing per capita living space are explored. Most SFHs in Sweden are old, in poor condition, and in urgent need of structural and energy retrofits. In addition, about one-third of homeowners are over 60 years old and report living in homes that are too large compared to their needs - an excellent environment to study the proposed intervention. Revenues from renting the newly created ADUs suggest that the proposal is financially attractive because it capitalizes on the high initial investment costs of energy retrofits. In addition, spatial interventions combined with energy-efficient measures result in a 40 percent lower energy use and environmental impact per capita compared to energy retrofits alone due to a reduction in per capita living space. Finally, the study aims to initiate a discussion on sufficiency, innovative energy regulations, and housing policy tools needed to transition to the low-energy single-family housing stock

Abstract [en]

Energy efficiency in buildings remains an important priority for the European Union. Towards that direction, the role of the one-stop-shops (OSSs) that will offer integrated renovation services has been further enhanced. The paper aims to compare public and private-driven OSSs to increase knowledge regarding the way they operate. The business models of ten OSSs for the renovation of residential buildings, operating in six European countries have been analyzed, and further evaluated for their engagement in the critical moments of the renovation customer journey. Findings show that the majority of examined OSSs have managed to reach some level of standardization in the way they deliver their service. Additionally, the examined OSSs appear to be engaged in the critical moment of the renovation customer journey, which can attract the interest of potential customers. Public-driven OSS appears to operate smoother in the renovation market and offer services that are considered crucial for their potential customers. Their viability though in the absence of public funding needs to be further examined. On the other hand, private-driven OSSs are called to deal with greater challenges in their effort to consolidate their presence in the renovation market. Providing access to financing remains a challenge for private-driven OSSs, which to attract more customers resort to value additions to their service, which might affect their viability. The study provides valuable information and insights about OSSs in operation that could be useful to stakeholders that are active in the renovation market or interested to enter it
