The increasing world population and climate change are major concerns for the supply of water needs. Understanding user behavior facilitates the development of effective strategies of domestic water management. This research applied a questionnaire survey and data analysis methods to analyze the water consumption behavior of tenants in a multicultural urban area, dominated by immigrants of different ethnic origins, in the city of Växjö in Sweden. Results showed that the majority of the studied participants perceived themselves to be environmentally friendly. They reported to be engaged in water conservation activities quite often, but analysis showed that they did not have accurate perceptions of their water consumption. Positive attitudes towards water conservation and self-reported water conservation activities significantly but negatively influenced respondents’ actual water consumption, i.e., water consumption was higher. Subjective norms did not have a significant influence. The results also revealed that individual measurement and debit positively influenced, i.e., reduced, actual water consumption. Therefore, water management systems should include an individual measurement and debit system combined with a visualization system to enable tenants to monitor the quantity and cost of their water consumption.

Triple Layer Business Model Canvas (TLBMC) is a tool helping us to explore sustainability-oriented business model innovation. It extends the business dimension of the canvas with the addition of an environmental dimension based on life cycle perspective and a social dimension based on stakeholder perspective. A combined consideration of the three dimensions of the business model allows us to understand how an organization generates economic, environmental and social values. This paper presents the TLBMC of One-Stop- Shop (OSS) business model for energy renovation of detached houses. This three-layer canvas allows us to under- stand how OSS creates different types of values related to energy renovation, by using elements of life-cycle analysis and stakeholder management. It also contributes to the identification of gaps in research on energy renovation of detached houses, which need to be filled in order to better quantify the benefits of energy efficient renovation in those dwellings and develop such an OSS that will serve better the growing needs of the urban environments of the future.

To address the renovation needs of detached house stock in Sweden, micro and small-sized enterprises (MSEs), a subgroup of small and medium-sized enterprises, are expected to introduce more comprehensive house renovation solutions. One-stop-shop (OSS) is an innovative Product-Service System model that can enable MSEs to offer comprehensive renovation packages instead of existing fragmented solutions. We have applied a conceptual framework for innovation adoption in organizations and conducted an interview of 21 construction MSEs in three different geographical areas in Sweden to examine their perceptions and preparedness to adopt the OSS business concept. Findings showed that the examined MSEs are positive towards OSS as it could address the needs for the comprehensive renovation of detached houses. However, presently, are not prepared to take the coordinator’s role in such a concept mainly due to the perceived business risks, the lack of flexibility to organizational restructuring, and lack of resources and management competency to coordinate multiple tasks and actors. Those organizations lacked awareness of existing policy support and access to funding mechanisms to try new business models. As a solution, they proposed an external coordinator to be the provider of OSS, on the trial phase, whose role and characteristics need to be further examined.

In this paper, we examine factors affecting owners’ intention for renovation of their detached houses. Furthermore, we analyze their interest in choosing a one-stop-shop (OSS) service for the renovation, even though such a concept is not yet established in Sweden, but emerging in other parts of Europe. Our study is based on responses to an online questionnaire survey of 971 house owners residing in Kronoberg Region in Sweden. About 76% of the respondents intend to renovate in the near future, with approximately 71% of them preferring to renovate individual components of their dwelling and 5% to renovate their whole house in steps. House owners of younger age, higher income, higher education, and those with an interest for environmental issues, were the ones most interested in physical renovations, which improves energy efficiency of the building. For those house owners, one-stop-shop can facilitate the decision-making process, and help them to choose those measures that will improve their quality of life. Approximately 20% of the respondents had a positive view towards an one-stop-shop, which is an indicator that market for such a service exists. Parameters such as quality of work, cost and energy savings and specification of measures to be adopted are the key for the promotion of one-stop-shop. Additionally, house owners want to have a certain level of involvement in the selection of actors performing the renovation. Moreover, financial incentives, e.g., loans, do not play a significant role for the selection of one-stop-shop, but act as complementary motive for house owners.

Based on an online questionnaire survey, this paper analyses the attitude of homeowners in Kronoberg, Sweden towards energy-renovation and one-stop shop (OSS) services for the deep renovation of detached houses. Personal and contextual variables have been analysed to know who have renovation plan, what motivates them to renovate and if there is an interest in OSS concept. Results have shown that at present a very small section of the homeowners’ have deep renovation plan. The priority is rather on aesthetic renovation than energy renovation. Younger homeowners below 36 years could be the first potential customer segment for deep renovation. The attitude towards OSS business concept of one entrepreneur-offering package solutions currently is not so encouraging. There is a need to demonstrate a cost-efficient OSS business concept for deep renovation ensuring the quality of the work to accelerate the deep renovation under such a business concept.

Existing studies of heating products have analyzed the adoption of energy-efficient heating technologies from diverse micro and macroeconomic aspects, such as diffusion of innovation, willingness to pay, business models, energy pricing, etc., but the analysis from a marketing management approach based on end customer insight is still lacking. Understanding the decision-making process of end customers, and the influence of social environment at the diverse stages of the purchase process leads to a focused market strategy, thereby contributes toward overcoming the multi-level segmentation challenge faced by the manufacturers of heating products. In this context, a two-step exploratory research was conducted in December 2013 with end customers of the residential heat market in Hungary. The end customers were found to be active decision-makers engaged in deliberate planning in the purchase of heating products. They start searching for information by turning mainly to online information sources and they actively integrate their social network in all stages of the decision-making process, which means that the role of the installer is relatively less influential along the whole purchasing process. Identified influencing communication channels at the diverse stages of the purchase process may support manufacturers to develop a user-centric marketing strategy by optimizing the communication instruments in their marketing mix by, for instance, including direct end customer communication via online channels and by de-emphasizing offline communication channels.

In this paper, we identify the socio-economic attributes and attitudes that have influenced house owners in renovating their homes in the past. Our study is based on responses to an online questionnaire survey of 971 house owners living in Kronoberg County in Sweden. Results showed that the interest and willingness of the house owners to perform a renovation varied depending on their demographic background and the age of the house. The latter positively affected past renovations, only when combined with the residence time. Furthermore, the age of house owners strongly and positively affected the probability of performing aesthetic type of renovations, because of a long time of residence in the house. Younger, town living, and highly educated house owners seem to be more concerned regarding saving energy, which motivated them to perform physical renovations on their house. Our results also suggest that income, level of education, and place of residence have an effect on renovation decisions only through their effect on the energy concern of house owners, and a varied effect on renovation decisions, when combined with the time of residence in the house.

The Swedish government aims to reduce total energy demand per heated building area by 50% until 2050. A large number of residential buildings, built within the so-called “Million homes program” in Sweden, need major renovations, which offers an opportunity to implement energy efficiency measures and thereby, reduce total energy demand. The best way to encourage the implementation of a major renovation is to demonstrate a practical method which reduces energy demand and provides economic benefits. Hence, this study aims to determine the most cost-effective energy solution in renovating a multi-family residential building. Multiple energy renovation measures were simulated on a case study to reduce the space heating and domestic hot water by 50%. The case study building was built within the “Million homes program” and is located in Växjö, Swedish climate zone 3. Design Builder software was used for analysing the pre-renovation energy performance of the building. The renovation measures comprised different insulation thicknesses of external walls, attic and ground floors, windows with different U-values, a mechanical ventilation with heat recovery system, and solar system for supporting space heating and domestic hot water. Later, a multi-objective optimization was accomplished for analysing every possible combination of renovation measures. The most cost-effective energy solution was obtained by calculating the net present value in a lifetime of 30 and 50 years and discount rate of 1, 3 and 5%. Comparing the implications of two different lifetimes on net present value with implications of three different discount rates on net present value shows that lifetime has more influence on net present value. Furthermore, the results show the capability of the multi-objective optimization method in analysing multiple renovation solution.

The selection of the most appropriate window and blind design is a challenging task due to the existence of potential conflicts between visual comfort, thermal comfort, energy consumption and life cycle cost. Resolving these conflicts relies on a trade-off window and blind design. This research applied a decision-making framework to select a trade-off window and blind design for an office room in Sweden. The decision-making framework was developed based on integrating the non-dominated sorting genetic algorithm-II and the analytical hierarchy process. The first step in the application of the framework was to generate a model of the office room using EnergyPlus. Six types of window and four types of blind; an internal venetian blind, an internal roller curtain, an external venetian blind and an external overhang panel, were modelled in EnergyPlus. The second step was to run an optimisation using non-dominated sorting genetic algorithm-II. For this purpose, various window and blind design variables were specified in modeFRONTIER platform. The third and last step in the application of the decision-making framework was to select a trade-off window and blind design using analytical hierarchy process. The results show the strength of the decision-making framework in selecting a trade-off design, and thereby the ability to resolve conflicts through intelligent use of simulation in analyzing big-data in built environment, energy and cost sectors. Since, the computation and processing power for performing simulations is constantly increasing, architects and designers can exploit the decision-making framework and locate a trade-off design in a relatively short period of time.

In the realm of industrial energy efficiency studies, very little research has been done to understand the barriers and opportunities to influence behavior of production workers and the corresponding energy-saving potentials. This paper analyzes a case study of Volvo Construction Equipment AB in Braås, Sweden (VCE Braås), that has reduced its relative idle electricity use by more than 10 percentage points during 2013–2016 by implementing a strategy of changing everyday behavior of production workers. The results based on interviews with actors involved in the energy efficiency project showed that a concrete goal, the employment of a fulltime operational leader who earlier worked as a production worker at VCE Braås, and the involvement of both the leadership and employees in project management were key to the success of the project.

The cost-optimal level of energy performance for buildings shall be identified according to the European directive of 2010. The Swedish building stock needs comprehensive knowledge and an overall strategy for the cost-optimal level of renovation. This paper studies the contribution of Swedish climate zones to the cost-optimal level of renovation on a multi-story residential building in Sweden from the building owner perspective. The building space heat demand is simulated for four Swedish climate zones. The net present profit (NPP) method is defined and used in this study in order to analyze the cost-optimal level and the cost-effective renovation of building envelope components (e.g., attic floor, basement walls, exterior walls and windows). The implication of different discount rates is studied, as well. The results show that the optimum renovation of the building envelope offers 51% more energy savings for space heating when the building is in a northern climate zone compared to a southern zone. The study suggests that different renovation strategies for the building stock renovation need to be identified, separately, for each climate zone. The NPP analysis identifies the minimum required investment and maximum achievable energy savings that are needed to have a cost-effective renovation. The broad range of studied climate zones provides the opportunity to apply the obtained results to other climate zones by either interpolation or extrapolation of NPPs for the buildings with similar characteristics.

Purpose The aim of this paper is to enhance the understanding of architects’ perceptions of the propensity to adopt innovations in building construction. Design/methodology/approach Based on a theoretical underpinning of the multilevel perspective on socio-technical transitions, a web-based questionnaire (n = 412) was used to empirically investigate Swedish architects’ perceptions of innovativeness in the building construction industry. Specifically, the study looks at perceptions of the level of innovativeness (propensity to adopt innovations), relevant barriers to the adoption of innovations, the influence of different actors and ways of facilitating innovativeness. Findings Architects perceive a low level of innovativeness in the Swedish building construction industry because of a number of barriers of varying relevance. These barriers belong to interwoven regulative, normative and cognitive rules (i.e. institutions) that guide actor behaviour, which contribute to the path dependency of the industry. The site-specific nature of building construction, promotional activities from suppliers and the level of competition in the industry is perceived as being of little relevance. The findings suggest that a number of interventions are necessary to facilitate innovativeness of the Swedish construction industry. To change the lock-in mechanisms of the established cognitive and normative rules, regulative rules need to change as well. According to architects, contractors and construction clients are the most influential and therefore have the most power to change the rules associated with path dependency. Research limitations/implications The focus on a single construction professional in Sweden necessitates a discussion on these perceptions from the standpoint of other actors. Practical implications Architects perceive a need for change in the construction industry and suggest that changed regulative rules can help overcome path dependency and facilitate innovativeness. Considering the strong interrelatedness of the lock-in mechanisms that guide the actors of the industry, policies may be needed to encourage and support the establishment for more sustainable development. Originality/value A multilevel perspective is used to analyse the type of barriers to innovativeness that the architects perceive as relevant and how they contribute to the resistance to change and path dependency in the building construction sector.

Window blinds have a substantial role in shaping the energy consumption and improving thermal comfort and visual comfort. However, difficulties in selecting a window blind remain, due to existence of potential conflicts between visual, thermal, energy and life cycle cost. To overcome this problem, this study evaluates the performance of interior blinds, including venetian with slat of 0° and 45°, roller and double-pleated blinds with respect to visual, thermal, energy and life cycle cost. Later, the Analytical hierarchy process (AHP) is used for selecting the best blind based on trade-off among the visual, thermal, energy and life cycle cost. In using AHP, visual comfort is determined as most important objective with a weight of 52%. The results show that venetian blind (VB) with slat of 0° drawn 100% is the trade-off blind. Accomplishing the sensitivity analysis on blinds’ global weight shows that VB with slat of 0° drawn 100% remains the trade-off blind until the weight of energy and life cycle cost is below 37% and 57%, respectively, and the weight of visual comfort is above 4%. However, changing thermal comfort weight has no impact on ranking of the blinds. This study shows the capability of AHP in managing the conflicts.

To deepen the understanding of the sociotechnical regime that directs the selection of structural frames in multifamily buildings in Sweden, we study the perceptions of contractor representatives. Contract managers (CMs) employed at contractor firms were interviewed regarding their role, the selection of the structural frame and how they perceived different options. The results show that CMs largely influence the selection of the structural frame in multifamily buildings, which are guided by the established concrete-based sociotechnical regime. The regime is maintained through cognitive rules regarding structural frame options and the alignment of skills of construction professionals. Because of their influence and their investments in the skills of construction workers, CMs make important contributions to maintain the regime and the concrete path dependency. Furthermore, the regime varies in strength in different locations. Some locations carry a strong norm to cast concrete frames on site. This makes it more difficult to deviate from the established practice. In other locations, wood-promoting initiatives have changed the cognitive rules associated with the regime. Nonetheless, the sociotechnical regime makes the selection of concrete structural frames beneficial. This prevents wood-framed multifamily buildings from entering common usage, even though such buildings can contribute to mitigating climate change.

Two eight-story wood-framed residential buildings with the Swedish 2012 passive house standard were built in 2009 in the Portvakten Söder quarter in the city of Växjö in Sweden. In this paper, we present the monitored specific energy use of the buildings and compare to the requirements of the Swedish building code and recommendation for passive houses. We also estimated the primary energy use and CO2 emissions and investigated the tenants’ views and experiences of the two buildings. Results show that the actual specific energy use of 40.2 kWh/m2Atemp/year in the Portvakten Söder building fulfills, by a good margin, the requirements of the Swedish building code and the recommended passive house standard, but is higher than projected. Applying a marginal perspective, the calculated primary energy use and carbon dioxide emission from operating the buildings (excluding household electricity) was 40 kWh/m2Atemp/year and zero, respectively. Responses of 20 tenants to a mail-in questionnaire survey showed that over 90% were satisfied with their apartments.

The use of intensive forestry on part of the forested area in Sweden increases the production of forest biomass and enables an increased use of such biomass to mitigate climate change. However, with increasing conflicting interests in forests and forestry, the success of such a strategy depends on the public acceptance. In this paper, the results of a mail survey show that although a majority of the general public in Sweden supports measures to increase forest growth, they oppose the use of intensive forestry practices such as the cultivation of exotic tree species, clones, and forest fertilization. The acceptance of such practices is mainly influenced by the perceptions of their environmental consequences. Public acceptance was highest for forest fertilization, whereas clone cultivation was the least accepted practice.

Swedish forest growth can be increased through intensive forestry practices, enabling an increased use of forest biomass for climate-change mitigation. However, the diffusion of such practices depends on the forest owners’ adoption of them. We study Swedish private forest owners’ perceptions and intentions with respect to increasing forest growth by adopting exotic tree species. The results of a mail-in questionnaire survey show that although a majority of forest owners desire increasing forest growth, most owners have only a basic understanding of exotic tree species and a smaller proportion is interested in adopting them. The intention to adopt exotics seems to depend on the perceived performance of the species with respect to the economic aspects of forest management rather than on environmental or recreational concerns. Whereas a knowledge gap among the private forest owners regarding how to increase forest growth is implied, forest owners with higher self-rated knowledge of forestry and exotics have stronger intentions to adopt such species.
