Konferensbidrag (refereegranskat)abstract
- In Nordic countries significant primary energy efficiency potential exists in houses built before 1980. These old houses need to be renovated, which provides an opportunity for implementation of energy efficiency measures. However, there are several economic and market barriers and the renovation market are dominated by handicraft-based individual solutions. In this project we analyze the opportunities for implementation of one-stop-shop business models where an overall contractor offers full-service renovation packages including consulting, independent energy audit, renovation work, follow-up (independent quality control and commissioning) and financing.A comparative assessment of emerging business models shows that different types of actors (renovation company, insulation company, energy utility, building product warehouse) can provide such a service. Financing is included in some models. There are differences in how customers are contacted, while the similarities are more on how the service is provided. A main challenge is how to secure independent advising and there is there is uncertainty over who will be responsible for guarantee of the renovation work if the service provider goes bankrupt.Even though there is strong business potential for one-stop-shop energy renovation concept, still it has been somewhat difficult to start or run such a business. Various options to overcome the barriers to promote energy efficient renovation of detached houses are discussed.

Cost-effectiveness of using wood frames in the production of multi-storey buildings in Sweden
- 2009
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Production cost of buildings is a complex issue to analyze with high variation and several uncertainties. In this report we give an overview of the production cost effectiveness of a change from traditional concrete-framed building practice to wood-frame building practice. The frame material itself may not significantly influence the production cost, but there is potential for cost reduction in the activities associated with a change from concrete to wooden frames. From the review of existing studies it could not be concluded that the production cost of wood-framed buildings was lower than that of a concrete-framed building. However, with increased construction, the production cost of wood-framed buildings could be reduced due to the influence of “learning”.

Deliverable 3.1 Report on possible financing schemes for one-stop-shop service for sustainable renovation of single family house : Report prepared for Nordic Innovation Centre
- 2011
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- There are significant potentials to improve energy efficiency of single-family houses in theNordic countries. Technical solutions exist, but there are market and financial barriers toimplementation of such measures. The aim of the report is to identify financial barriers toimplement energy efficiency measures in Nordic single family houses and to discuss optionsto address those barriers.In the initial phase of a market formation, the targeted potential customers (the “innovators”who are few in numbers) usually have capacity to invest in energy-efficient measures.However, such measures, though cost effective in a life-cycle perspective, often incur highinvestment cost and majority of the consumers tend to stick to the least efficient products.Moreover, a lack of awareness about the possible energy efficiency measures, including theirbenefits, and the uncertainty regarding the level of energy savings due to a lack ofstandardised measurements and verifications protocol may not encourage, both the customersand financiers, to go for energy efficiency investments. Financiers perceive energy efficiencyprojects as risky investments maybe because of their small size, difficulty to control energyuse behaviour of the occupants and the difficulty to predict future energy prices.The options to finance energy efficiency renovations include homeowners’ own resources,mortgage refinancing, flex loan, personal loan, financing by service providers, preferentialloan, subsidies/grants, credit cards, and financing supported by guarantee on energy savings.Each option has its own advantages and disadvantages. It is less likely that the one-stop-shopservice providers in Nordic countries, at present, will give any guarantee on actual savings inenergy use or cost. But, such a concept is emerging in some European countries and could bean option in future.The best option to finance energy efficiency improvements in Nordic countries seems to bethat one-stop-shop service providers collaborate with commercial banks to offer mortgagerefinancing. Such a mechanism is convenient for the homeowners, and banks will have a lessrisky asset in their portfolio. In situations where homeowners cannot avail additionalmortgage financing, e.g. those who recently purchased a house and used the limit to suchloans, banks may consider an energy efficient renovation plan prepared by an entrepreneurand pre-evaluate the post-renovation value of the house. This pre-renovation valuation couldform the basis for the bank to confirm the homeowner and the service provider that certainamount of investment cost would be available from mortgage refinancing. To cover the costthat exceeds the amount available from mortgage financing (or base loan), nationalgovernments may consider to provide soft loans or subsidies.In countries where tax deduction on home renovation is available, amendments should bemade to such programs to incorporate specific requirements regarding energy efficiency ofimplemented measures. Also, higher tax deduction could be offered for energy efficiencyimprovement than for other renovation. Moreover, a simple tool to inform the homeownersabout the cost-efficiency of energy renovation investment would be that banks and utilitiescollaborate to send a joint invoice which contains the monthly cost of mortgage loan and theenergy cost.

Deliverable 3.2 Report on business models for one-stop-shop service for sustainable renovation of single family house : Report prepared for Nordic Innovation Centre
- 2011
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- The aim of the report is to analyze and develop one-stop-shop business models to offer fullservicerenovation packages in the Nordic countries. The report will contribute to identifypotential models that can be tested in pilot studies and will be an important source of marketinformation for companies planning to develop a one-stop-shop concept.In Nordic countries significant primary energy efficiency potential exists in houses builtbefore 1980. These houses are more than 30 years old and need to be renovated. This providesan opportunity for implementation of energy efficiency measures, but the renovation market isdominated by handicraft-based individual solutions. There is a need for one-stop-shopbusiness models where an overall contractor offers full-service renovation packages includingconsulting, independent energy audit, renovation work, follow-up (independent qualitycontrol and commissioning) and financing. There is a significant business potential for such amodel as the renovation market for single-family houses could be in the order of hundreds ofmillion Euros per year in each Nordic country. Homeowners will get an improved qualityrenovated house with little risk or responsibility which usually is the case with traditionalrenovations, the energy cost will be reduced, market value of the house is likely to increase,mortgage banks will have a safer asset and there are societal benefits in terms of reducedenergy use and greenhouse gas emission. However, there is uncertainty over who will beresponsible for guarantee of the renovation work if the service provider goes bankrupt.Insurance companies could be involved to address this issue.A comparative assessment of models proposed in the Nordic countries shows that differenttype of actors may play the key role in a one-stop-shop for energy efficient renovation ofsingle-family houses. In some models the service provider collaborates with financinginstitutions to provide renovation financing. There are differences on how customers arecontacted, while the similarities are more on how the service is provided. A main challenge ishow to secure independent advising.Even though there is strong business potential for one-stop-shop energy renovation concept,still it has been somewhat difficult to start or run such a business. One of the main reasons isthe uncertainties about the customer base. One way to attract more customers is to offersubsidies for energy efficiency measures. In Denmark, Sweden and Finland there are taxdeductions for labour cost for home renovation and other household work. An amendment tosuch programs to incorporate specific requirements regarding energy efficiency ofimplemented measures could be a way to increase homeowners’ interest in energy efficientrenovation. A guarantee on energy or energy cost saving may encourage energy efficientrenovation of houses as energy cost saving is one of the most important factors in thehomeowners’ decision to implement energy efficiency measures. At present it is less likelythat such guarantee will be given as the full service energy renovation concept is yet to betested and not enough experience exists regarding energy savings potential in the context ofvarying household energy behaviour. Highlighting the energy (e.g. cost reduction) and nonenergybenefits (improved thermal comfort or indoor air quality) of energy efficiencyimprovements may create customer interest in energy efficient renovations. Some of theexisting models include financing by the service providers in collaboration with financinginstitutions. To support the mortgage financing of energy efficiency renovations, governmentcould provide soft loans or subsidies to cover the investment cost beyond the mortgage (base)loan.

Diffusion of energy-saving innovative heating systems in Sweden - a consumer survey approach
- 2006
-
Ingår i: Proceedings. ACEEE Summer Study on Energy Efficiency in Buildings 2006, August 13-18, Pacific Grove, California (CD-ROM).
-
Konferensbidrag (refereegranskat)abstract
- In Sweden, considerable energy efficiency and greenhouse gas mitigation could be achieved through the conversion of 500,000 detached houses from electricity-based heating systems to district heating, heat pumps or pellet boiler systems. House owners are central in the diffusion of innovative heating systems as they make the adoption decision. Hence, we carried out an empirical analysis of the factors affecting house owners� decisions to adopt a heating system. In June 2005 we sent out questionnaires to about 700 Swedish house owners residing in the city of Östersund, whose houses were originally built with resistance heaters. The results reveal that about 84% of the respondents had no plans to install a new heating system. Economic aspects, functional reliability and indoor air quality were the important factors in respondents� choice of a heating system. A district heating system has advantages with respect to functional reliability, indoor air quality, maintenance cost, system automation and time required for collection of information. A bedrock heat pump system has advantages with respect to annual cost of heating, indoor air quality, security of fuel supply, environmental benignity and market value of the house. A pellet heating system has an advantage with respect to investment cost.

Tidskriftsartikel (refereegranskat)abstract
- The Swedish homeowners' perception of Innovative Heating Systems (IHSs) was studied through a questionnaire survey. Most of the respondents were satisfied with their existing heating systems and were not planning to install a new one. They considered economic factors and functional reliability the most important factors in the choice of a heating system. Hence, economic policy instruments appear to be efficient in inducing homeowners to install an IHS. Installers were the most important source of information. The perceived advantages of pellet boilers were fewer than those of heat pumps and therefore, they were diffusing slower than heat pumps in Sweden.

Ingår i: Proceedings. 14th European Conference and Technology Exhibition on Biomass for Energy Industry and Climate Protection, Paris (France), 17-21 Oct 2005. - Florence : ETA.
-
Konferensbidrag (refereegranskat)abstract
- A questionnaire survey of 1500 detached house owners was carried out in the autumn of 2004 to find out the factors influencing the adoption and diffusion of pellet heating systems in the Swedish residential sector. Results revealed that most of the respondents are satisfied with their existing heating systems and have not planned to install new heating systems. Economic aspects and functional reliability are important factors in the respondents� choice of heating system while environmental factors are of less importance. Therefore, internalizing external costs, such as environmental costs, might be effective in influencing house owners to adopt environmentally benign heating systems. Installers are the most important source of information on heating systems. Hence, they should be trained to inform the consumer comprehensively about different heating systems. Respondents perceive the relative advantage of pellet boilers over oil or electricity-based heating systems, but bedrock heat pumps are considered better than pellet boilers and therefore diffuse faster.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- In this paper we introduce a microeconomic modelling framework for the analysis of the adoption and diffusion of wood pellet heating systems that explicitly takes into account the cost of competing systems, differences in service and maintenance costs, and system switching costs. We also introduce an aggregate technology diffusion model that allows for the inclusion of economic explanatory variables and a limited degree of heterogeneity among adopters. Furthermore, we touch upon the issue of system boundaries in the context of technology adoption decisions, how alternative environmental and energy policies may affect the adoption and diffusion of pellet heating systems, and what guidelines welfare economics theory proposes regarding the optimal speed of technological diffusion.

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

Ingår i: eceee 2013 Summer Study proceedings. - : European Council for an Energy Efficient Economy (ECEEE). - 9789198048223 ; , s. 529-536
-
Konferensbidrag (refereegranskat)abstract
- In Sweden, more than 80% of the single-family houses are more than 30 years old and majority of them need some renovation. This provides opportunities for implementation of energy efficiency measures, which depends on homeowners’ adoption-decision. Results from several surveys by us showed that more than 80% of the Swedish homeowners consider annual energy cost and investment cost to be the two most important factors in the choice of energy efficiency measures. They preferred investment subsidies and tax deduction on energy efficiency measures, but did not like energy and carbon taxes on energy use. We discuss marketing and policy measures to overcome various obstacles to energy renovation of detached houses. A marketing measure is to introduce one-stop-shop business models where a single actor offers all types of services, including financing, required to undertake energy renovations. A national goal for energy efficiency improvements in existing buildings coupled with a list of actions needed to achieve that goal and tailored incentives will help to establish a market for energy renovations. For an owner of detached house, the goal could be set by energy-certificate, and then one-stop-shop service would provide the plan and actions needed to reach the goal.

Tidskriftsartikel (refereegranskat)abstract
- The Växjö municipality sets specific energy related requirements beyond the Swedish building code (BBR) when selling land for the construction of new residential buildings. The requirement for Östra Lugnet residential area was that all buildings must be connected to the local district heating network and installation of heat pumps was prohibited in developer-built group/row houses. This paper (a) analyzed if the energy use of the buildings fulfilled the requirements of the BBR and that of Växjö municipality, and (b) compared the primary energy use and CO2 emission from operation of the district heated buildings with hypothetical scenarios where only air-source or bedrock heat pumps were installed. Results showed that a significant proportion of the group/row houses did not fulfil the specific energy use requirements of the BBR and that of Växjö municipality. There were large variations between predicted and actual energy use. Using a marginal accounting approach, houses with district heating were found to have the lowest carbon emission. From this perspective it seems appropriate for Växjö municipality to set the requirement that new residential buildings in Östra Lugnet be connected to the local district heating network.

- The Växjö Municipality in Sweden sets specific energy requirements above the national building code while sellingland for new residential buildings. A main energy requirement for Östra Lugnet residential area in Växjö was that allbuildings must be connected to the district heating network. In this paper we analysed final energy use of thebuildings, and compared the primary energy use and CO2 emission from operation of the buildings connected todistrict heating system with hypothetical scenarios where only air-source heat pumps were installed. The resultshowed that district heating is the better option from the perspective of lower carbon emission. Therefore, it seemsappropriate for Växjö Municipality to set conditions for new residential buildings in Östra Lugnet to connect to thelocal district heating network as it contributes to its goal of low carbon society.

Full service energy efficient renovation business for Swedish single-family houses
- 2011
-
Ingår i: Proceedings of SB11 Helsinki World Sustainable Building Conference.
-
Konferensbidrag (refereegranskat)abstract
- More than 80% of the Swedish single-family houses were built prior to 1977 when energyefficiency was introduced in the national building code. These houses are more than 30-40 yearsold and need renovation. This provides a unique opportunity for large-scale implementation ofenergy efficiency measures. However, there is a lack of business model to introduce full serviceenergy efficiency renovation packages that include consulting, contract work, follow-up andfinancing. Under the Nordic project “Successful Sustainable Renovation Business for Single-FamilyHouses – SuccessFamilies”, we have conceptualized a new business model to offer such a fullservice package to the Swedish homeowners. The new business could be offered by existingconstruction/renovation companies in collaboration with energy auditors/building consultants andheating system retailers/installers. The business could be targeted to houses built during 1971-80as the primary energy efficiency potential is significant in this segment. Especially houses that areon sale could be targeted because people usually do indoor renovation when they buy a houseand therefore, they may be interested in energy efficient renovations. Banks may consider postrenovation value of the newly-bought house based on planned renovation package from anentrepreneur to provide increased mortgage finance for renovation. Other options to improveenergy efficient renovation of single family houses include tax subsidies, preferential loans andguarantee on energy or energy cost savings.

Rapport (övrigt vetenskapligt/konstnärligt)abstract
- The market penetration of multi-storey wooden buildings, and regulations, perceptions and promotion of such construction varies among Germany, the Netherlands, Ireland, United Kingdom (UK) and Sweden. It seems that the wood construction system in Sweden is passing from a formative phase to growth phase, while in all other countries they are still in the formative phase. Conditions for market growth of multi-storey construction seem to be most favourable in Sweden followed by Ireland, UK, Germany and the Netherlands.

Ingår i: 17<sup>th</sup> European Biomass Conference and Exhibition – From Research to Industry and Markets, 29 June – 3 July, Hamburg, Germany.
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Sweden leads in use of wood pellets for space heating. The oil crises of the 1970s and the concern for climate change in the early 1990s contributed significantly to the market development. Installation of pellet boilers in detached houses has grown tremendously, but to further improve market demand an understanding of homeowners’ perception of such heating system vis-à-vis other heating systems is required. We conducted questionnaire surveys of 1500 randomly selected owners of detached houses in autumn 2004, spring 2007 and summer 2008. Respondents consistently gave high priority to economic aspects and functional reliability in their choice of a heating system, while environmental factors were given less importance. Therefore, internalizing the external costs in homeowners heating cost might be effective in influencing homeowners to adopt environmentally benign heating systems. Respondents thought that pellet boilers had the lowest investment cost, while district heating system was most functionally reliable. Heat pumps were considered best with respect to the annual cost of heating, environmental benignity, increased market value of the house, and low greenhouse gas emission.

Homeowners’ attitude towards one-stop-shop business concept for energy renovation of detached houses in Kronoberg, Sweden
- 2019
-
Ingår i: Innovative Solutions for Energy Transitions. - : Elsevier. ; , s. 3702-3708
-
Konferensbidrag (refereegranskat)abstract
- 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.

Ingår i: Applied Energy. - : Elsevier BV. - 0306-2619 .- 1872-9118. ; 86:2, s. 144-154
-
Tidskriftsartikel (refereegranskat)abstract
- Improved energy efficiency and greenhouse gas mitigation could be achieved by replacing resistance heaters with district heating system. In 2005, only about 8% of the Swedish detached houses had district heating system. The expansion of such systems largely depends on homeowners’ adoption decisions. And, to motivate homeowners to adopt district heating, it is essential to understand their decision-making process. In this context, in June 2005 we carried out a questionnaire survey of about 700 homeowners who lived in the city of Östersund in houses with resistance heaters (baseline survey). About 84% of the respondents did not intend to install a new heating system. Since then these homeowners were influenced by (a) an investment subsidy by the Swedish government to replace resistance heaters with district heating, a brine/water-based heat pump, or a biomass-based heating system and (b) a marketing campaign by the municipality-owned district heating company. This paper analyses how these two measures influenced about 78% of the homeowners to adopt the district heating system. For this purpose we carried out a follow-up survey of the same homeowners in December 2006 (resurvey). Results showed that the investment subsidy and the marketing campaign created a need among the homeowners to adopt a new heating system. The marketing campaign was successful in motivating them to adopt the district heating system. The marketing strategy by the district heating company corresponds to the results obtained in the baseline survey.

Tidskriftsartikel (refereegranskat)abstract
- The paper focuses on Swedish homeowners' perceptions of innovative heating systems, and those factors that influence their decision to adopt a new heating system. The systems studied were: district heating, heat pumps and pellet boilers. Results of two household surveys - one covering the whole of Sweden in autumn 2004 and the other in the city of Östersund in summer 2005 - revealed that approximately 80% of the survey respondents, particularly those with resistance heaters, did not intend to install an innovative heating system. Economic aspects, functional reliability and indoor air quality were found to be the most important factors influencing respondents' choice of a heating system. Survey respondents thought that a bedrock heat pump system has a number of advantages with respect to the annual cost of heating, security of fuel supply, environmental benignity, market value of the home and low greenhouse gas emission. A district heating system has advantages regarding functional reliability, system automation and time required to obtain information. A pellet boiler system has one main advantage: investment cost. Compared with homeowners having other types of heating systems, those with resistance heaters accorded more importance to investment cost due to the high cost of installing a water-based system for heat distribution within the home.

Multi-storey timber buildings – breaking industry path dependency
- 2008

Ingår i: Building Research & Information. - : Informa UK Limited. - 0961-3218 .- 1466-4321. ; 36:6, s. 638-648
-
Tidskriftsartikel (refereegranskat)abstract
- The Swedish legal restriction on construction of multi-storey timber buildings was imposed in 1888 and repealed in 1994. The subsequent emergence of such a timber building system in Sweden is analysed in the context of the existing concrete-based construction system. The characteristics of the construction industry and its path dependency over the past century hamper the development of a timber building system. However, government policies and funding, the wood industry’s interest in an enhanced market for value-added wood products, and involvement of the wood research community has helped develop such a construction system. Investments in knowledge creation, incentives for the entry of new firms, and increased prefabrication may facilitate a transition from this formative phase to a growth phase in the diffusion of timber buildings.

One-stop-shop service for sustainable renovation of single family house : Summary Report
- 2012
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- The Nordic project “Successful Sustainable Renovation Business for Single-Family Houses (SuccessFamilies)”, with participants from Denmark, Finland, Norway and Sweden, deals with development of business models for full service energy efficient renovation of detached houses in Nordic countries. The background to this project is that the majority of these houses are more than 30 years old and need to be renovated, which provides opportunity for implementation of energy efficiency measures. The renovation market is dominated by handicraft-based individual solutions. There is a need for onestop-shop business models where an overall contractor offers full-service renovation packages including consulting, independent energy audit, renovation work, independent quality control and commissioning, and financing. There is a significant business potential for such a model as the volume of renovation market for single-family houses can reach hundreds of million Euros per year in each Nordic country. The project team analysed emerging business models to offer full-service renovation packages in the Nordic countries. A comparative assessment shows that different types of actors (renovation company, insulation company, energy utility, building product warehouse) can provide such a service. There are differences in how customers are contacted, while the similarities are more on how the service is provided. A main challenge is how to secure independent advising. Even though there is strong business potential for one-stop-shop energy renovation concept, still it has been somewhat difficult to start or run such a business. Various options to overcome the barriers to promote energy efficient renovation of detached houses are discussed in the final report.

Perceptional and socio-economic factors in adoption of low energy houses
- 2009
-
Ingår i: International Scientific Conference on Energy systems with IT, March 11-12, in connection with 'Energitiget 2009', Stockholm, Sweden.
-
Konferensbidrag (refereegranskat)abstract
- 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 experiences
- 2008
-
Ingår i: 14th Annual International Sustainable Development Research Conference, 21-23 September, New Delhi, India.
-
Konferensbidrag (refereegranskat)abstract
- 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.

Tidskriftsartikel (refereegranskat)abstract
- Alabastern, a multicultural rental housing area in the Växjö city of Sweden, was identified as poor at recycling household waste compared to other housing areas in the town. In this paper, a qualitative and quantitative analysis is conducted to understand the underlying causes of waste recycling behavior of the tenants. Results showed that majority of the studied participants perceived themselves to be environmentally friendly. They reported that they recycled household waste quite often, but it was the other tenants who did not sort their waste properly. The respondents identified the causes of the improper waste recycling as lack of attitude and awareness, limitation of communication, sense of insecurity, lack of means to transport bulky waste, limitation of the recycling room, and inadequate action by the housing company Vï¿œxjï¿œbostï¿œder.

Report on business models for one-stop-shop service for sustainable renovation of single family house, Deliverable D3.2 : Successful Sustainable Renovation Business for Single-Family Houses – SuccessFamilies
- 2011
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- In Nordic countries significant primary energy efficiency potential exists in houses built before 1980. These houses are more than 30 years old and need to be renovated. This provides an opportunity for implementation of energy efficiency measures, but the renovation market is dominated by handicraft-based individual solutions. There is a need for one-stop-shop business models where an overall contractor offers full-service renovation packages including consulting, independent energy audit, renovation work, follow-up (independent quality control and commissioning) and financing. There is a significant business potential for such a model as the renovation market for single-family houses could be in the order of hundreds of million Euros per year in each Nordic country. Homeowners will get an improved quality renovated house with little risk or responsibility which usually is the case with traditional renovations, the energy cost will be reduced, market value of the house is likely to increase, mortgage banks will have a safer asset and there are societal benefits in terms of reduced energy use and greenhouse gas emission. However, there is uncertainty over who will be responsible for guarantee of the renovation work if the service provider goes bankrupt. Insurance companies could be involved to address this issue.The aim of the report is to analyze and develop one-stop-shop business models to offer full-service renovation packages in the Nordic countries. The report will contribute to identify potential models that can be tested in pilot studies and will be an important source of market information for companies planning to develop a one-stop-shop concept.A comparative assessment of models proposed in the Nordic countries shows that different type of actors may play the key role in a one-stop-shop for energy efficient renovation of single-family houses. In some models the service provider collaborates with financing institutions to provide renovation financing. There are differences on how customers are contacted, while the similarities are more on how the service is provided. A main challenge is how to secure independent advising.Even though there is strong business potential for one-stop-shop energy renovation concept, still it has been somewhat difficult to start or run such a business. One of the main reasons is the uncertainties about the customer base. One way to attract more customers is to offer subsidies for energy efficiency measures. In Denmark, Sweden and Finland there are tax deductions for labour cost for home renovation and other household work. An amendment to such programs to incorporate specific requirements regarding energy efficiency of implemented measures could be a way to increase homeowners’ interest in energy efficient renovation.A guarantee on energy or energy cost saving may encourage energy efficient renovation of houses as energy cost saving is one of the most important factors in the homeowners’ decision to implement energy efficiency measures. But, at present it is less likely that such guarantee will be given as the full service energy renovation concept is yet to be tested and not enough experience exists regarding energy savings potential in the context of varying household energy behaviour. However, such concepts exist for industrial and public buildings (the ESCO concept) and are emerging for residential buildings. Highlighting the energy (e.g. cost reduction) and non-energy benefits (improved thermal comfort or indoor air quality) of energy efficiency improvements may create customer interest in energy efficient renovations.One way to kickstart the market is to provide public funding for few demonstration projects to test different business models, e.g. those identified in this report. Such projects will bring together actors interested in one-stop-shop concept and they will gain some experience. In such demonstration projects the full-scale energy renovation actions could be realised in shorter timeframe than in traditional piecemeal renovations. Advertisement of results of successful demonstration projects may attract more customers and entrepreneurs.Existing models in Denmark and Finland include financing by the service providers in collaboration with financing institutions. Still, mortgage financing is the most cost efficient option to finance energy efficiency renovation of single-family houses (Mahapatra et al. 2011). However, the need to selffinance the amount not covered in the mortgage loan may not encourage homeowners to go for energy efficiency renovation. This could be addressed if government provides soft loans or subsidies to cover the investment cost beyond the mortgage (base) loan. Attention should be given to the limitation of mortgage financing for energy efficient renovation of recently bought houses. Banks may consider an energy efficient renovation plan prepared by an entrepreneur and pre-evaluate the postrenovation value of the house in collaboration with real estate agents. This valuation could form the basis for the bank to confirm the homeowner and the entrepreneur that certain amount of investment cost would be covered by mortgage refinancing.

Small-scale pellet heating systems from consumer perspective
- 2006
-
Ingår i: Proceedings. 2nd World Conference on Pellets, 30 May-1 June 2006, Jönköping, Sweden.
-
Konferensbidrag (refereegranskat)abstract
- A questionnaire survey of 1500 detached house owners was carried out in the autumn of 2004 to find out the factors influencing the adoption and diffusion of pellet heating systems in the Swedish residential sector. The results revealed that most of the respondents had no plans to install new heating systems as they were satisfied with their existing ones. Economic aspects and functional reliability were the most important factors in the respondents� choice of heating system while environmental factors were of less importance. Therefore, internalizing external costs, such as environmental costs, might be effective in influencing house owners to adopt environmentally benign heating systems. Installers were the most important source of information on heating systems. Hence, it is important that they could inform the consumers comprehensively and accurately about different heating systems. Respondents perceived the relative advantage of pellet boilers over oil or electricity-based heating systems, but bedrock heat pump system was ranked higher than pellet heating system in every aspect except for investment cost. Pellet heating system has advantage over district heating system with respect to investment cost and annual cost of heating. District heating system was considered as most functionally reliable and automatic.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- In the context of global warming and dependence on fossil fuels, modern bioenergy systems have appeared as important sustainable energy solutions with a large untapped potential in Sweden and the rest of the European Union. Small-scale pellet heating systems for space heating of small houses is one of these solutions. In Sweden, such systems have relative advantages over oil- or electricity boiler systems both in terms of greenhouse gas emission reduction and total lifetime cost of equipment and fuel. However, so far the market diffusion process of this technology has been rather slow. This paper, by employing concepts and insights from the literature of evolutionary economics and sociology, studies the factors involved in the diffusion of such systems.

Konferensbidrag (refereegranskat)abstract
- 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.

Konferensbidrag (refereegranskat)abstract
- In Sweden, there is opportunity to implement energy efficiency measures in about one million existing apartments that are likely to be refurbished within the next 20 years. System analyses of installation of energy efficient windows, and increased insulation in attic and in exterior walls for an existing multi-story building showed that the primary energy savings for the measures depend on the energy supply system. Energy efficiency potential was higher with installation of efficient windows than improved attic insulation. Responses of 673 chairpersons of co-operative hosing associations to a mail-in survey in 2010 also showed that greater proportion of respondents perceived that energy efficient windows had advantages over insulation improvements. However, majority had no intention to implement such measures during next 10 years and economic factors guide their decisions. Lack of expertise to assess the benefits of energy efficiency measures was the most cited hindrances to energy efficiency investments.

Konferensbidrag (refereegranskat)abstract
- The building sector is responsible for more than 40 % of the energy use and 32 % of carbon dioxide emissions in the European Union (EU). Previous research has shown that the present rate of energy retrofit and refurbishment in Europe is far below (<50 %) than that is required to meet the EU's building related energy efficiency goals for 2020. Appropriate policy interventions for deep renovation is perceived as a catalytic agent in promoting energy efficiency and leveraging more investments in the building sector. EU directives regarding Energy Efficiency reflects in various member states' national targets and policy measures to improve the energy performance of the existing building stocks. Economic policy instruments seem to be influential in steering the deep renovation market, but this alone may not be sufficient for the sustainable growth of the market. There is a need for market-based approach to enhance the private sector involvement, both in terms of technical and financial capabilities. This paper evaluates the policy instrument used for promoting deep renovation of residential buildings in the Netherlands. A "Theory-based evaluation" technique has been used in analyzing the content of the policy instrument, and the underlying theories and policies, at output and impact level. A set of the evaluation criteria have been applied for assessing such policy instruments in leveraging energy efficiency investments and their effectiveness in terms of energy savings. The assessments are done based on the meta-analysis of relevant literature and data sources, and finalized in consultation with the Dutch partners from INNOVATE (Integrated solutions for ambitious energy refurbishment of private housing) project under Horizon 2020. Further, the challenges for scaling up such existing effort for the sustainable growth of the deep renovation market has been explored.

- Buildings are responsible for 40% of energy consumption and 36% of CO2 emissions in the EU. Sweden andDenmark are cold climatic countries with strong demand for space heating and hot water in the residentialsector. Large section of the detached houses in these countries are built more than 30 years ago and needrefurbishment. Despite of huge energy saving potentials with deep renovation of these houses, there existsseveral challenges in realizing those saving potentials. This paper evaluates the market for deep renovation ofsingle-family houses in these two Nordic countries using PEST and SWOT analysis. Comparative analysisbetween two countries will help to understand the common and country specific drivers and barriers and todevelop strategic recommendation in accordance.

-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- This paper presents the challenges and possibilities in the journey of establishing One-Stop-Shop (OSS) for energy renovation with three case examples. The paper compares three models; municipality owned (Cyprus), private and public-private partnership with operational support from municipalities (Netherlands), and privately owned and market based (Sweden) OSS models. The study is based on the situational analysis with market gap identification for the energy renovation of the dwellings and CANVAS analysis of the studied OSS models. The commonalities and peculiarities of different OSS models have been closely observed and the strength and weaknesses within these models are critically discussed. The analysis have shown that lack of awareness, inconvenience and cumbersome renovation process and lack of access to finance are the common challenges of energy renovation market. The study has also shown that the OSS model and its setting up journey may vary depending upon the market conditions, readiness, existing level of government support, and nature of the organization willing to initiate the OSS.

Tidskriftsartikel (refereegranskat)abstract
- Deep renovation of the buildings is a key for sustainable development, however, the rate of deep renovation of residential buildings in the European Union (EU) is lower than what is required to meet the climate and energy goals. This paper analyses peculiarities and commonalities in market conditions and approaches to the deep renovation of single-family (or detached) houses in Denmark and Sweden. The market analysis covers the Political, Economic, Social, and Technical (PEST) dimensions and is based on systematic literature review and findings of market gap analysis. The PEST analysis is complemented with responses from 49 stakeholders/experts to examine the strengths, weaknesses, opportunities, and threats (SWOT analysis) for the deep renovation market. The synthesis of SWOT and PEST led to some strategies for deep renovation. Furthermore, policies and strategies adopted by some other countries have been discussed to place findings from this study in the regional and global context. Capacity building in designing and managing deep renovation with technological advancement and construction practices; and enforcement of quality assurance systems of artisans could avoid the perceived risk, and inconveniences associated with renovation. Encouraging systematically planned stepwise deep renovation through One-Stop shop and linking such renovation with appropriate financing mechanism could attract more homeowners with financial limitations. Besides, clustering several houses in need of renovation and appropriate energy/carbon pricing mechanisms could make the renovation market more attractive for investors and construction companies. The findings of this paper are of interest to construction companies, policymakers, investors, and analysts about the deep renovation market.

Urban Heat Island Risk Assessment and Mapping in the Swedish Residential Sector
- 2023

Konferensbidrag (refereegranskat)abstract
- 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.

Communication and Household Adoption of Heating Products in Hungary
- 2019
-
Ingår i: Energies. - : MDPI. - 1996-1073. ; 12:2, s. 1-22
-
Tidskriftsartikel (refereegranskat)abstract
- 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.

- The aim of this paper is to examine the role of social influence on the end customer behaviour in the purchase of heating products in residential segment. The study is based on interviews and questionnaire survey of homeowners in Hungary in 2013. Respondents are open to learn about diverse innovative heating technologies, energy types and diverse heating fuels irrespective of any purchase intention. They plan their purchase based on deliberate considerations rather than facing an emergency heating appliance breakdown. Furthermore, influence of the social environment prevails at the diverse stages of the purchase process. End customers actively conduct social search (family, friends, neighbours, colleagues, other customers with purchase experience over the Internet, etc.) besides the influencing role of the installer.

Tidskriftsartikel (refereegranskat)abstract
- Industrial plants in Iran, similar to many other developing countries, use diesel or natural gas generators mainly as backup power during a grid outage. Depending on the electricity network configuration, these emergency generators might be able to deliver electricity to the grid and thereby contribute to demand response (DR) programs. Hence, Iran's Ministry of Energy (MOE) has policies and incentives to promote the use of emergency generators during peak hours. This paper investigates the economic and carbon dioxide emission implications of such DR policies by the MOE. Results show that the current policy promotes diesel generators that are economically beneficial to the companies but are more carbon intensive than the natural gas generators. To mitigate the climate change with a minimum impact on the economic interest of the companies, the future DR policies can be amended. The revised incentive structure proposed by this study is simple but effective and ensures that the lower carbon emitting natural gas generators would become more economically attractive than diesel generators. Following the proposed approach to set the incentives, the natural gas generators would be more beneficial according to the MOE policy in 2019 if the difference between the diesel incentive and natural gas incentive was less than 711 Rial.

A business model canvas framework for sustainable one-stop-shops
- 2022
-
Konferensbidrag (refereegranskat)abstract
- 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.

Konferensbidrag (refereegranskat)abstract
- 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.

Comparing public- and private-driven one-stop-shops for energy renovations of residential buildings in Europe
- 2022
-
Ingår i: Journal of Cleaner Production. - : Elsevier. - 0959-6526 .- 1879-1786. ; 365
-
Tidskriftsartikel (refereegranskat)abstract
- 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

- Based on an online survey, this paper analyzes the attitude of detached house owners in Sweden toward future renovations and their perception over a one-stop-shop (OSS) service for deep renovation of these dwellings. With the aid of a house owners’ renovation decision-making journey for renovation, personal and contextual variables have been analyzed to identify those house owners having renovation plans in the near future, what they are going to renovate, and which needs to lead them to that decision. Furthermore, we examine if there is an interest in OSS concept and the factors affecting positively or negatively the choice for such a concept. Results suggest that deep renovation is not yet prioritized. The priority for house owners is to change specific components of their dwelling and follow a step-wise approach. Aesthetic renovations are high on the agenda, with some structural and energy-related renovations following them. House owners between 29 and 49 years of age are those mostly interested in more comprehensive renovations. The OSS concept appears to be interesting to a number of house owners capable to verify a business potential. House owners up to the age of 45 years, with dwellings built from 1960 and above and with environmental awareness, are the market segment that can act as early adopters of the OSS concept. When it comes to the decision-making journey for renovations, house owners’ future plans, and the factors affecting their choice for an OSS provider, we can claim that OSS can act as a guide for house owners from the early stages of their decision-making journey and provide them with a shortcut that will make this journey more secure, while triggering renovation decision of greater extent. In terms of financing, incentives related to energy performance are also suggested as means that could boost greater interest for more comprehensive renovations.

- This paper examines the views of construction SMEs in Sweden regarding innovations, in particular the one-stop-shop business concept,and its adoption for renovation of detached house. The investigation is based on interviews with 10 construction SMEs and by applying aconceptual framework for organizational innovation adoption. The results suggest that, even though the one-stop-shop businessconcept is perceived as a means for growth, at present, construction SMEs in Sweden are unlikely to adopt it at present. This lackof interest is mostly related to the perceived complexity of this model and the underlying risks and uncertainties. That complexity isseen as a preventing factor as it puts at stake their current business. The interviewees proposed that there should be an entrepreneur to coordinate the actors involved in the renovation process, whose role can be further studied.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- This study examines the views of stakeholders involved in house renovations regarding the one-stop-shop business concept innovation, and assesses their level of preparedness to adopt such a concept in order to enter the promising market of detached house renovations. The investigation is based on 25 interviews with construction SMEs owners, real estate agents and loan consultants, and on a conceptual framework for organizational innovation adoption. The results suggest that for the nonce, none of the examined stakeholdersis likely to adopt a one-stop-shop business model to enter the market of detached house renovations, even though this concept is seen as one with great potential. This mostly happens due to their individual characteristics, the complexity of one-stop-shop model related to their way of doing business and the uncertainties deriving from the adoption of such a model. Furthermore, the participation of an entrepreneur is proposed, who would coordinate all the different actors involved in the renovation process, and whose role can be further examined.

Konferensbidrag (refereegranskat)abstract
- The current rate of residential building renovations in Europe is inadequate and attributable to the lack of integrated solutions in the market supported by appropriate business models. One-stop-shop (OSS) offers an innovative business approach, and it is acknowledged by the European Commission, in the Directive 2018/844/EU, as a transparent advisory and facilitating tool for the establishment of services relevant to energy efficiency renovations for buildings. This paper evaluates two different delivery mechanisms of OSS, namely public-driven and private-driven, using six examples of OSSs business models currently operating in five European countries. The study is based on document and records-based research, and the analysis of data is done through a standardized blank profile for each OSS including parameters based on the deliberations of Osterwalder and Pigneur's business model canvas.A comparative analysis of the models has been conducted to identify repetitive patterns, commonalities, and differences between them. The study has shown that the examined OSSs are still in a developing stage, struggling to achieve enough scale, which indicates the need to lower their costs, reorganize their models and streamline the value chain to become attractive to their targeted customer segments. Public-driven OSSs appear to be, for the nonce, better positioned in the market and their reliance on public money allows them to achieve some expansion of their activities, even if this cannot be considered a sustainable business solution in the long run. Private-driven OSSs need to work harder to strengthen their position in the market and increase their attractivity. Towards that direction, the contribution of policy interventions and re-adjustment of existing financing mechanisms could be further examined.
