    Implementering av energieffektiviseringsåtgärder i befintlig bebyggelse: Report prepared for the Swedish Energy Agency2010Report (Other academic)
    Abstract [en]

    There is great potential to improve energy efficiency in existing Swedish residential buildings. However, the successful implementation of efficiency measures depends on economical and technical factors, as well as on the attitudes and perceptions of the relevant actors. A better understanding of their attitudes and perceptions may influence the design of suitable policy measures that increase the adoption of energy efficiency measures. In this context, we conducted mail-in surveys completed by owners of detached houses, chairmen of co-operative housing associations (bostadsrättsförening) and municipality energy advisers in Sweden. We also interviewed window sellers/installers in Jämtland.

    Results show that it was important for the majority of homeowners to reduce their household energy use, with most undertaking no-cost measures (e.g., switching off lights). However, 70–90% of the responding homeowners had no intention of adopting building envelope measures over the next 10 years. The main reason for non-adoption was that homeowners were satisfied with the physical condition and thermal performance of their existing building envelope components. Homeowners who thought their energy cost was high were more likely to adopt an investment measure compared to those who thought their energy cost was low. Investment costs and annual energy cost savings were the most important factors in adoption of energy efficient building envelope measures. Therefore, economic incentives may induce homeowners to adopt energy efficiency investment measures. However, a large percentage (64%) of homeowners was unaware of the existence of government support for reducing household energy use. Information campaigns announcing the availability of economic incentives and the cost advantages of energy efficiency measures may be helpful in the adoption decision.

    Homeowners‘ considered interpersonal sources, builders, installers and energy advisers as important sources of information for their adoption of energy efficiency measures. Though a large percentage of respondents considered energy advisers as an important source of information, only 14% of homeowners had contacted an energy adviser in the past. Our findings suggest that the energy advice service is important for homeowners, but more efforts are needed to increase homeowners‘ awareness of and satisfaction with such services. The majority of municipal energy advisers were of the opinion that more training in technical aspects of energy issues and increased financial support could improve their performance.

    Installers and material suppliers are important actors in homeowners‘ adoption of energy efficiency measures. For example, approximately 53% of responding homeowners to a survey in Jämtland/Västernorrland stated that the window seller/installer from whom they had bought windows had recommended a particular type of window, and 97% had ii

    installed the windows that were recommended. The window sellers/installers in Jämtland prefer a window that is ―reasonably‖ energy efficient. They believe that windows with a U-value of 1.2 W/m

    2K are good and there is no reason to further improve the energy efficiency. The majority did not recommend windows with U-value <1.2 W/m2K. They were concerned about the condensation issues and high prices of such windows. This may influence the diffusion of very energy efficient windows in Swedish detached houses.

    About 80-95% of chairmen in co-operative housing associations who responded to our survey had no intention of adopting building envelope measures over the next 10 years. They were satisfied with the existing building envelope components, which may be one of the reasons for this lack of intention. As in the case of owners of detached houses, economic factors, like annual energy cost savings and investment costs, guide the implementation of energy efficiency investment measures in co-operative housing associations. However, about 66% of the responding chairmen did not consider financial constraint as a barrier to implementing investment intensive energy efficiency measures. For 54% of the respondents limited in-house competency to evaluate the benefits of energy efficiency measures was the main barrier.

    The majority of owners of detached houses (80%) and chairmen of co-operative housing associations (70%) perceived that economic policy instruments, such as investment subsidies and tax deductions, would encourage them to implement energy efficiency measures. Other policy instruments, especially information instruments, were perceived as less effective. Among various information policies, increasing the frequency of meter reading received the highest approval with 38% of homeowners, whereas approximately 41% of housing association chairmen thought that individual metering of heating and hot water use could be effective. Approximately 30% of homeowners and housing association chairmen thought that energy declaration was effective.

    Implementing energy efficiency measures in existing Swedish building stock2008In: World Sustainable Energy Days 2008, 5-7 March 2008, Wels, Austria, 2008Conference paper (Refereed)
    Abstract [en]

    There is a large potential for improving energy efficiency in the existing Swedish building stock. However, how successful the implementation of the efficiency measures will be, depends on economical and technical factors as well as on the attitudes and perceptions of the relevant actors. In this paper we use Rogers’ diffusion of innovation theory to analyze various factors affecting implementation of energy efficiency measures in the Swedish detached houses and apartment buildings. Results of recent Swedish household surveys concerning adoption of heating systems showed that majority of the respondents were satisfied with their heating systems and did not intend to install a new one. Economic aspects and functional reliability were important factors in the choice of heating systems, while installers/vendors were the most important sources of information on heating system. We discuss upcoming empirical studies on implementation of other energy efficiency measures, e.g. energy efficient windows and additional insulation, including that of heating systems, in detached houses and apartment buildings.

    Swedish homeowners’ perceptions of innovative heating systems – results of three surveys2009In: ECEEE 2009 Summer Study, 1-6 June 2009, La Colle sur Loup, Côte d'Azur, France, 2009Conference paper (Refereed)
    Abstract [en]

    Replacing oil and electric heating systems with innovative heating systems (IHSs) such as bedrock heat pumps, district heating system, and pellet boilers will significantly reduce greenhouse gas emission from Swedish detached houses. However, realizing this potential depends on homeowners’ adoption decision, which is influenced by their need, awareness and perception of the advantages associated with the IHSs. In this context, we conducted mail-in questionnaire surveys of 1,500 Swedish homeowners, selected through stratified random sampling method, in Fall 2004, Spring 2007, and Summer 2008. A response rate of 42%, 48% and 37% was obtained in the 2004, 2007 and 2008 surveys, respectively. One of the aims of the series of surveys was to find out if external factors such as provision of investment subsidies and mass media discussion of climate change issues had influenced homeowners awareness and perception of the advantages associated with the IHSs. Results showed that there was no appreciable change in homeowners’ perceptions between the years surveyed. They consistently gave higher priority to economic factors over environmental factors in their decision to install a new heating system. Heat pumps were best perceived with respect to the annual energy cost of heating, environmental benignity, increased market value of the house, and low greenhouse gas emissions. Respondents felt that pellet boilers had the lowest investment cost, while district heating system had the perceived advantage of functional reliability.

    Energy advice service as perceived by Swedish homeowners2011In: International Journal of Consumer Studies, ISSN 1470-6423, E-ISSN 1470-6431, Vol. 35, no 1, p. 104-111Article in journal (Refereed)
    Abstract [en]

    External actors can influence potential adopters to adopt energy efficiency measures. In Sweden municipality energy advisers are one such actor group who provides energy advice and information to the end users. The success of energy advice service for improvement of energy efficiency of detached houses depends on homeowners' perception towards it. In this context, we conducted a national survey of about 3000 owners of detached houses through stratified random sampling method in the summer of 2008. We found that majority of owners of detached houses consider energy advisers as an important source of information. Furthermore, many homeowners who contacted energy advisers for advice had implemented the suggestions. However, only a few homeowners had contacted an energy adviser. Our findings suggest that it is beneficial to continue the energy advice service, but more efforts are needed to increase homeowners' awareness of and satisfaction with such services.

    Perceptional and soicio-economic factors in adoption of low energy houses2009In: International Scientific Conference on Energy systems with IT, March 11-12, in connection with 'Energitiget 2009', Stockholm, Sweden., 2009Conference paper (Refereed)
    Abstract [en]

    Diffusion of low energy houses reduces greenhouse emission from residential sector. However, adoption of such houses depends on the perception of the potential buyers. In this paper we have analyzed Swedish homeowners’ perception of low energy houses. Data was collected in 2008 from a mail-in questionnaire survey of about 3000 owners of detached houses. Results showed that about 39% of respondents, especially young, educated or whose household income was high, would consider buying a low energy house. Majority of the respondents agreed that a low energy house in comparison to a conventional house has lower operating energy cost, but higher investment cost. Majority thought that low energy houses do not have lower resale value, lower aesthetic appearance, or greater operational difficulty.

    Policy instruments to promote energy efficiency in the building sector: Indian and Swedish experiences2008In: 14th Annual International Sustainable Development Research Conference, 21-23 September, New Delhi, India, 2008Conference paper (Refereed)
    Abstract [en]

    Energy efficiency measures in buildings are widely regarded as cost effective options to mitigate climate change. However, policy instruments are needed to improve the diffusion of such measures. The policy mix may be country-specific. Here, we compare and contrast the various policy instruments designed to enhance energy efficiency in the building sector in India and Sweden. The objective is to explore if the experiences of Sweden that have promoted energy efficiency in buildings for decades could be useful for India, where energy demand is forecasted to strongly increase. India and Sweden are very different, for example, in terms of development, size, priorities, population, and climatic conditions. In Sweden, policy initiatives to reduce energy use in buildings date back to the 1970s and the government is committed to significantly reduce energy use in buildings. In India, the interest in energy efficiency improvements in buildings is a recent phenomenon. The country introduced an energy conservation building code in 2007. This analysis shows that policy instruments are more prevalent in Sweden than in India where regulatory instruments are particularly lacking. Hence, Swedish buildings are more energy efficient than those in India. The Swedish experience could be useful for devising programs and implementing policy instruments to improve energy efficiency of Indian buildings.

    Swedish energy advisers' perceptions regarding and suggestions for fulfilling homeowner expectations2011In: Energy Policy, ISSN 0301-4215, E-ISSN 1873-6777, Vol. 39, no 7, p. 4264-4273Article in journal (Refereed)
    Abstract [en]

    Municipality energy advice services were re-introduced in Sweden in 1998 as a way of advising end-users, mainly owners of detached houses, on energy issues. In this paper, we investigate Swedish energy advisers' perceptions of homeowners' awareness of the energy advice service and their perceived ability to fulfil homeowners' expectations. Our study is based on a mail-in questionnaire survey conducted in 2009 and distributed to municipality energy advisers in all municipalities in Sweden. About 66% of the energy advisers responded. The results show that 43% of the energy advisers thought that fewer than 50% of the homeowners were aware of the service and that mass media advertisements and presentations at different organisations could improve homeowner awareness. Energy adviser attitudes, job satisfaction, and the perception that the advisers possessed up-to-date and good knowledge and sufficient financial resources to execute their duties had a significant influence on their perceived ability to fulfil homeowner expectations. Increased training in technical aspects of energy measures and increased financial support were the two measures most widely suggested as a means to improve energy advisers' performance.

    Implementation of energy efficiency measures in Swedish single-family houses2012Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Energy efficiency improvements in the residential sector have manybenefits, such as reducing greenhouse gas emissions, improving energy security,creating jobs and improving living conditions. There is a large potential to improveenergy efficiency in existing Swedish residential buildings. Many of the energyefficiency measures that can be implemented in buildings may be cost effective.However, the successful implementation of efficiency measures depends onmultiple factors, including the attitudes and perceptions of the relevant actors. Insingle‐family houses the homeowners are important actor in the diffusion ofenergy efficiency measures as they are the final decision makers regarding whetherto adopt such measures. An adopter‐centric approach was used to studyhomeowners’ adoption and intention to adopt energy efficiency measures. Twomail‐in questionnaire surveys of owners of single‐family houses were conducted;one was a national survey, and the other was sent to selected households in twocounties that had installed energy‐efficient windows. The government fundedchange agents and private actors like sellers/installers could influencehomeowners’ adoption decisions. Accordingly, a survey of municipality energyadvisers across Sweden and window sellers/installers in Jämtland County wasconducted to understand their perception and attitude towards energy efficiencymeasures.The results show that the majority of homeowners considered it importantto reduce their household energy use, with most of them preferred to undertakeno‐cost measures (e.g., switching off lights). The majority of respondinghomeowners (70-90%) did not intend to improve their building envelopecomponents mainly because they were satisfied with their existing components.Investment costs and annual energy cost savings were the most importantfactors in the adoption of energy‐efficient building envelope measures.Homeowners who considered their energy costs to be high were more likely toadopt an energy efficiency investment measure compared to those who thoughttheir energy costs were low. Though the majority of homeowners did not considertheir energy cost as high still they considered it important to reduce householdenergy cost. Therefore, economic incentives may induce homeowners to adoptsuch measures. Increasing the energy price may induce more homeowners toadopt energy efficiency measures as the higher energy price may further improvethe cost effectiveness of such measures. However, majority of homeowners did notconsider energy and CO2 taxes as effective policy instruments that encourage themto adopt energy efficiency measures.iiHomeowners considered interpersonal sources, builders, sellers andinstallers to be important sources of information regarding the adoption of energyefficiency measures. Energy advice service could be an important policy tool topromote energy efficiency, but about 50% of the homeowners are unaware of thisservice. Only 14% of homeowners had consulted an energy adviser out of which57% (i.e. 8% to total respondents) had implemented the suggestions. Hence, moreefforts are needed to increase awareness and effectiveness of energy advice service.The majority of municipal energy advisers were of the opinion that increasedfinancial support and more training in technical aspects of energy issues couldimprove their performance.Actors close to homeowners in the supply chain, such as sellers andinstallers, could play an important role in homeowners’ adoption of energyefficiency measures. Approximately 97% of responding homeowners who receiveda recommendation about particular windows from a seller/installer had installedthe recommended windows. The window sellers/installers in Jämtland prefer awindow that is reasonably energy efficient. The majority will not recommend awindow with a U‐value of < 1.2 W/m2K mainly because they were concerned aboutcondensation issues and about the high prices of such windows. Approximately80% of homeowners who availed themselves of the investment subsidy installedwindows with a U‐value of 1.2 W/m2K. Like the window sellers/installers,homeowners cited condensation issues and high prices as reasons for not buyingmore energy‐efficient windows. This finding suggests that windowsellers/installers have strong influence in homeowners’ choice of windows.Therefore to increase the adoption rate of more energy‐efficient windows inexisting single‐family houses, it may be necessary to address windowsellers’/installers’ concerns about these windows.

    Adoption of energy efficiency measures in swedish detatched houses2009In: International Scientific Conference on Energy systems with IT, March 11-12, in connection with 'Energitiget 2009', Stockholm, Sweden., 2009Conference paper (Refereed)
    Abstract [en]

    The paper focuses on Swedish homeowners’ need for and perceptions about adopting building envelop energy efficiency measures such as improved windows and attic and wall insulation. The results of a questionnaire surveying 3000 randomly selected homeowners during the summer of 2008 revealed that about 70-90% of the respondents had no intention of implementing such a measure over the next 10 years. The main reasons for non-adoption were that homeowners were satisfied with the physical condition, thermal performance, and aesthetics of their existing installations. A greater proportion of respondents perceived that improving attic insulation has more advantages than other measures, but windows were more likely to be installed than attic insulation was to be improved. Respondents gave high priority to economic factors in deciding on an energy efficiency measure, while environmental aspects were given lower priority. Hence, economic incentives could be useful in promoting the adoption of building envelope energy efficiency measures. Interpersonal sources, construction companies/installers, and energy advisers were important sources of information for homeowners as they planned to install energy efficiency measures.

    Factors influencing energy efficiency investments in existing Swedish residential buildings2010In: Energy Policy, ISSN 0301-4215, E-ISSN 1873-6777, Vol. 38, no 6, p. 2956-2963Article in journal (Refereed)
    Abstract [en]

    We used the data from a survey conducted in 2008 of 3,000 owners of detached houses to analyse the factors that influence the adoption of investment measures to improve the energy efficiency of their buildings. For the majority of Swedish homeowners, it was important to reduce their household energy use, and most of them undertook no-cost measures as compared to investment measures. Personal attributes such as income, education, age and contextual factors, including age of the house, thermal discomfort, past investment, and perceived energy cost, influence homeowners’ preference for a particular type of energy efficiency measure. The implications for promoting the implementation of energy efficiency investment measures are discussed.

    Abstract [en]

    The paper focuses on Swedish homeowners’ need for and perceptions about adopting building envelop energy efficiency measures. The paper is based on a questionnaire survey of 3059 homeowners (response rate of 36%) selected by stratified random sampling during the summer of 2008. The results showed that 70–90% of the respondents had no intention of adopting such a measure over the next 10 years. The main reasons for non-adoption were that homeowners were satisfied with the physical condition, thermal performance, and aesthetics of their existing building envelope components. A greater proportion of respondents perceived that improved attic insulation has more advantages than energy efficient windows and improved wall insulation, but windows were more likely to be installed than improved attic insulation. Respondents gave high priority to economic factors in deciding on an energy efficiency measure. Interpersonal sources, construction companies, installers, and energy advisers were important sources of information for homeowners as they planned to adopt building envelope energy efficiency measures. Policy measures to facilitate the rate of adoption of energy efficient building envelope measures are discussed.

    Implementation of energy efficient windows in Swedish single-family houses2012In: Applied Energy, ISSN 0306-2619, E-ISSN 1872-9118, Vol. 89, no 1, p. 329-338Article in journal (Refereed)
    Abstract [en]

    A questionnaire survey of 1010 homeowners in Jamtland and Vasternorrland, which are two counties in central Sweden, was conducted to understand the factors influencing their decision to install energy-efficient windows. We complemented this survey with an interview of 12 window sellers/installers in the county Jamtland. The annual energy cost reduction, age, and condition of the windows were the most important reasons for the window replacement decision. Approximately 80% of the respondents replaced their windows with energy-efficient windows with U-value of 1.2 W/m(2) K. Condensation problems, perceived higher prices, and lack of awareness about windows with lower U-values were important reasons for non-adoption of more energy-efficient windows. Window sellers/installers have a strong influence on homeowners' window selection that was indicated by the 97% of homeowners who bought the windows that were recommended to them. Sellers/installers revealed that they did not recommend windows with U-value of less than 1.2 W/m(2) K because they thought that investing in such windows was not economical and because windows with U-value less than 1.2 W/m(2) K could cause water condensation on the external surface of window pane.
