During the last decades, a variety of digital tools have been developed to support both planning and management cities, as well inclusion civic society. Here, concept Digital Twin – which is rapidly emerging throughout many disciplines due advances in technology, computational capacities availability large amounts data plays an important role. In short, twin living virtual model, connected representation physical system has central manufacturing industry for past decades. this article, we...

Applying the model of absorptive capacity (ACAP), antecedents, predictors and moderators for green innovation performance in construction industry are investigated. The aim is to identify mechanisms that influence environmental a company. Data come from questionnaire survey assessing attitudes, management within Swedish industry. For data analysis, linear regression analysis was used. From testing ACAP theory model, it concluded has promising potential explaining behind performance....

The transition to a circular economy (CE) produces range of new challenges for designers and requires specific knowledge, strategies, methods. To date, most studies regarding design CE have been theoretical conceptual, hence, limited research has conducted on the practical implications designing CE. Therefore, aim this study is provide better understanding how practitioners interpret implement concept in practice. capture complexity real-world cases, semi-structured interviews were carried...

Renovation processes are complex and there is a risk of underestimating architectural, cultural, social values in favor exterior interior upgrading, energy efficiency financing. A synthesized, systematic process needed for making decisions about renovation measures. The aim this paper to survey decision-making procedures aimed sustainable renovation. We inventory existing tools methodologies based on (a) literature review (b) results from workshop with participants the Swedish buildings...

Several building-stock modelling techniques have been employed to investigate the impact of energy efficiency measures (EEM), where description generally consists an age-type classification specify building characteristics for groups buildings. Such descriptions lack appropriate level detail differentiate potential EEM within age groups. This paper proposes a methodology using building-specific data and measured use augment classification. By integrating from performance certificates,...

Today, urban planning processes involve many stakeholders and efficient dialogue tools are needed to support communication in transdisciplinary environments. The aim of our study is identify visualization challenges planning. Based on a state the art thematic analysis 114 articles, published 2004–2014 found through snowball sampling, development implementation digital for discussed. A wide range examples has been found; either based 2D maps, 3D environments or gaming. initiators originate...

The European building stock was renewed at a rapid pace during the period 1950–1975. In many countries from this time needs to be renovated. There is an opportunity introduce energy efficiency measures in renovation process, but process social aspects should also taken into account. purpose of article provide estimate economic and societal challenge renovating retrofitting aging stock. Building specific data on usage previous investments made multi-family dwellings Gothenburg (N = 5 098)...

The compact city is an ideal model for sustainability, transferred between cities as ‘best practices’. This article investigates how context-adaptive transfer of ideals can take place, using Barcelona, Rotterdam and Gothenburg examples. objectives are to 1) summarize urban qualities discussed by stakeholders in the three cities; 2) uncover dominant challenges strategies among stakeholders; 3) present Barcelona/Rotterdam practices’ translated transformed into situated ‘good data were...

Abstract A large share of construction material stock (MS) accumulates in urban built environments. To attain a more sustainable use resources, knowledge about the spatial distribution MS is needed. In this article, an innovative analysis approach to proposed. Within scope, indicators are defined at neighborhood level and clustered with k ‐mean algorithms. The estimated bottom‐up (a) material‐intensity coefficients (b) data for three environment components: buildings, road transportation,...

Urban building-stocks are responsible for a significant share of resource and energy use. To quantify the potential reducing environmental impact, building-stock modelling (BSM) is commonly used. Recently, focus BSM has expanded to include impacts life-cycle assessment (LCA). However, impact categories often limited climate change representative buildings In addition, future state stock calculated as step-change highlight technical an ideal state. The aim this paper assess development urban...

To bridge the gap between conceptualisation and implementation of circular value propositions, recent research efforts have focused on linking design-driven approaches with circular-oriented innovation. Such can facilitate iterative processes that emphasise co-creation, prototyping, real-life experimentation, ultimately promoting practical implementation. Still, there is a lack understanding how companies go through process innovation, prototyping co-creation support this process. This...

To accomplish the sustainability potential of sharing economy (SE), there is a need for proactive governance SE. In this paper, we aim to generate knowledge on household product consumption and support SE in Gothenburg City (Sweden). Data from two independent cross-sectional questionnaire surveys were statistically analyzed, which generated insights within 7 groups covering durables; 20 demographic categories regarding gender, age, dwelling type, education level, family composition, income....

Cost-effectiveness of deep renovation has been assessed thoroughly on a building level. Such studies provide limited guidance when prioritizing measures for portfolio. On stock level, building-stock modelling is commonly used to assess impact national and city targeting stakeholders operating at planning or policy However, due methodological choices data availability, assessment property owner portfolios lacking. The aim this paper calculate spatially differentiate cost-effectiveness using...

The compact city concept remains a key policy response to multiple societal challenges. Based on theoretical and empirical research, this article seeks a) develop systemic understanding of qualities; b) map alleged qualities from the literature onto framework; c) mentioned by stakeholders in two European cities same d) apply developed framework analyse how compounded relate challenges, such as carbon neutrality, poverty alleviation, neighbourhood revitalization, or community engagement. It...

City Digital Twins have emerged as pivotal tools for representing and modelling urban systems. While existing literature emphasizes technological framework development, limited attention has been given to the practical usability of digital twins in planning decision-making processes. This paper addresses this gap by presenting a participatory approach city twin (CDTE) specifically tailored supporting stakeholder communication energy transition domain. The study, conducted three phases,...

AbstractIn order to understand the long-term change processes, a longitudinal study of Swedish construction industry is presented. This examines environmental attitudes and practices within this industry, particularly trends significant changes in corporate management performance. The results from three surveys undertaken 2002, 2006 2010 indicate that work becoming institutionalized as strategic part companies' business, activities integrated practices. Also evident greater maturity raised...

Urban building-stocks use a significant amount of resources and energy. At the same time, they have large potential for energy efficiency measures (EEM). To support decision-making planning, spatial building-stock models are used to examine current state future development urban building-stocks. While these normally focus on specific cities, generic broad stakeholder groups such as planners policy makers often targeted. Consequently, visualization communication results not tailored...

Sustainable urban transformation requires comprehensive knowledge about the built environment, including people's perceptions, use of sites, and wishes. Qualitative interviews are conducted to understand better opinions a specific topic or location. This study explores automatization interview coding process by investigating how state-of-the-art natural language processing techniques classify sentiment semantic orientation from transcribed in Swedish. For analysis, Swedish bidirectional...
