Konferensbidrag (refereegranskat)abstract
- 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.

- 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.

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.

Adoption of energy efficiency measures in swedish detatched houses
- 2009

Konferensbidrag (refereegranskat)abstract
- 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.
