“…Even direct monetary support or tax cuts could be used, since these may provide enough employment and new tax income to cancel out any apparent costs to the government. Campaigns to share information and showcase building retrofits done by other people might also boost interest in making energy renovations [65]. Shifting the emission reduction burden away from individual building owners is another possibility.…”

Towards the EU Emission Targets of 2050: Cost-Effective Emission Reduction in Finnish Detached Houses

et al. 2019

To mitigate the effects of climate change, the European Union calls for major carbon emission reductions in the building sector through a deep renovation of the existing building stock. This study examines the cost-effective energy retrofit measures in Finnish detached houses. The Finnish detached house building stock was divided into four age classes according to the building code in effect at the time of their construction. Multi-objective optimization with a genetic algorithm was used to minimize the life cycle cost and CO2 emissions in each building type for five different main heating systems (district heating, wood/oil boiler, direct electric heating, and ground-source heat pump) by improving the building envelope and systems. Cost-effective emission reductions were possible with all heating systems, but especially with ground-source heat pumps. Replacing oil boilers with ground-source heat pumps (GSHPs), emissions could be reduced by 79% to 92% across all the studied detached houses and investment levels. With all the other heating systems, emission reductions of 20% to 75% were possible. The most cost-effective individual renovation measures were the installation of air-to-air heat pumps for auxiliary heating and improving the thermal insulation of external walls.

“…Relevant issues have been the barriers that inhibit EE investment and give rise to the energy efficiency gap, and drivers that can help reduce or overcome a barrier and encourage investment. Nevertheless, most studies have focused on elaborate taxonomies and categorizing barriers and drivers [17][18][19][20][21][22][23], as opposed to empirically studying their influence on EE investment [24][25][26][27][28][29][30][31][32][33]. Below is a review of some of the most relevant studies in the literature, in which we first comment on papers related to barriers and their classification, focusing in particular on the principal-agent problem; secondly, papers related to drivers and their classification are discussed, and thirdly, empirical papers related to the influence of barriers and drivers on investment are considered.…”

“…Authors applying these methods have studied the influence of barriers and drivers on EE investments, attitudes towards them and policy implications, considering aspects such as the sector of activity, the characteristics of firms, commercial buildings and dwellings, the type of tenure and the investment decision, the selection of different EEMs or aspects related to the EEMs adoption. Some authors have studied EE investment decision as a binomial factor, binary decision or as the possibility to invest or not [25,27,28,32,33,67,68,105,124,132,133].…”

“…Investment can be encouraged by providing and strengthening financial incentives and support [27,28,105,147] through subsidies and policies related to public financing [89,103] and focusing on low-income tenants and third-party financers [74]. This is supported by the facts that landlords, who are able to afford EE investments, are more likely to invest [143], and that subsidies may be more effective in promoting energy-efficient technologies than energy price increases [68,133].…”

The Influence of Economic Barriers and Drivers on Energy Efficiency Investments in Maritime Shipping, from the Perspective of the Principal-Agent Problem

2020

View full text Add to dashboard Cite

Maritime transport stands out as a strategic sector; the increasing trend in maritime traffic makes it essential to reduce energy consumption and emissions through investment in energy efficiency. However, investments can be hindered by barriers, and drivers are necessary to reduce or overcome them and promote investment. Consequently, the purpose of this study is to analyze what factors influence investment decisions—and how they do so—when there are principal-agent problems in the shipowner–charterer relationship. The methodology is based on the following process: model and hypotheses formulation, variable definition, the creation of a study sample and statistical treatment through a descriptive analysis of variables and a binomial logistic regression model, all based on a state-of-the-art application. The results corroborate the hypotheses and indicate that principal-agent problems and split incentives, especially in time charter contracts, and a lack of verified information make the shipowners less likely to invest. Moreover, energy efficiency measures are less likely to be implemented in older vessels, possibly due to the difficulty associated with recovering the investment; they are more likely in larger and newer vessels, and regulation encourage their adoption. Furthermore, investment is more likely in vessels with verified information and high levels of both activity and harmful emissions. Improved knowledge in this field could help businesses and governments to act in a more sustainable manner, without detriment to an innovative and competitive sector.

“…A study in Finland [43] revealed that concerns for climate change among a segment of house owners influenced them to show greater willingness to receive advice and services towards Several studies have investigated house owners' decisions regarding adoption and diffusion of energy efficiency measures in their dwellings, e.g., heating systems, windows, building envelope measures, etc. [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28]. Previous studies examined the influence of sellers/installers on the decision of house owners to adopt a single measure (like e.g., energy efficient windows) [29][30][31][32], or the relationship between potential buyers and sellers of houses, and the incentives both sides require adopting energy efficiency measures prior or post purchase of the house [33,34].…”

Physical vs. Aesthetic Renovations: Learning from Swedish House Owners

et al. 2019

View full text Add to dashboard Cite

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