“…At the beginning of the research and monitoring for this article, grants were at the original level shown for the HES scheme in Table 1 but part way through the testing period the grant levels are as shown for the BEH scheme in the same table. Each of these impacts energy use in the home [6][7][8][9][10][11][12][13]. Historically in Ireland, building design mainly focused on meeting aesthetic and functional needs over thermal performance of the design.…”

a b s t r a c tThe residential sector represents 27% of primary energy consumption in Ireland. This paper examines the case study of the Irish government's national grant scheme to encourage energy efficiency retrofit in private housing. That is the Home Energy Saving (HES) Scheme, later rebranded the Better Energy: Homes (BEH) Scheme. The methodology involved monitoring several homes immediately before and after retrofit alongside discussions with occupants. The examination focused on specific measures commonly introduced through the HES/BEH programme − cavity and external wall insulation. It has been found that a significant decrease in heat loss through the walls was measured in all cases. Regardless, the occupant played a considerable role in the change in energy use in the buildings, and the main motivation for retrofit was found to be comfort and not energy savings or environmental concerns. As a result, the actual energy savings are notably less than the potential savings had the pre and post comfort levels remained the same.

“…Based on a literature review of energy conservation strategies, both in-home and out-of-home (Achnicht, 2012; Barr et al, 2005;Brechling & Smith, 1994;Erath & Axhausen, 2010;Ferguson, 1993;Jensen et al, 2012;Nair, Gustavsson, & Mahapatra, 2010;Rasouli & Timmermans, 2016), four options were selected: investing in energy-efficient/energy production equipment at home such as a solar panel, investing in exchanging the current car to an energy-efficient car, investing in a new/extra energy-efficient car such as a hybrid car or EV, and investing in relocation of home or work to shorten the total travel distance. These strategic choice options thus cover facility investment, energy-efficient car investment, and relocation investment (shortening travel distance).…”

This article explores consumer investment choice in long-term energy conservation technology and assesses trade-offs in energy saving behaviour between the housing and transportation domains. The long-term energy conservation choice problem is conceptualized as a portfolio choice problem. Consequently, to measure trade-offs between investments in housing and transport options, a cross effects choice design is developed in which respondents were shown one or more alternate ways to reduce their current energy consumption: (1) investing in new technology in the house, such as solar panels; (2) exchanging the current car for a more energy efficient car; (3) buying a new energy-efficient car, such as EV or solar car; (4) moving house to reduce current travel distances. To help respondents linking these options to their current energy consumption, a new Web-based survey system (SINA) to implement and administer stated adaptation experiments was developed. The system was used to collect two sets of data. First, data about out-of-home and in-home energy consumption, together with detailed time use data, was collected. Second, using a cross effects design, respondents were asked to select a portfolio of energy-saving strategies in response to different energy pricing policy scenarios. Results reported in this paper are based on 572 respondents who completed the survey and responded to seven adaptation questions based on their current energy expenditures. A random parameters logit model is estimated to predict the probability of choosing a particular portfolio of energy-saving options. Estimation results indicate that individuals from different socio-demographic groups exhibit varied preferences. The saving option characteristics, especially cost related characteristics have significant effects on individuals' preferences. Moreover, the results also showed significant effects of choice set composition on energy saving options. Further, the energy pricing policies had showed mixed effects on individual's preferences.

“…The sample sizes of respondents reporting why they did not adopt efficiency measures were also very low. Nair et al (2010) use survey data from 3,000 owner-occupiers living in detached houses in Sweden asking about their recent investments in energy efficiency measures. Whilst they do not report the significance of individual characteristics in driving these decisions, descriptive statistics suggest that on average, those livings in older buildings, experiencing discomfort from cold drafts, and those with higher incomes, are more likely to invest in measures.…”

Abstract We use English household-level survey data from 1996 to 2010 to explore whether economic market failures play a significant role in explaining the presence of energy efficiency measures (loft insulation, cavity wall insulation and full double glazing) in residential properties. There appears to be a limited role for credit constraints as proxied by income, receipt of means-tested benefits or educational attainment. Private renters are significantly less likely to own efficiency measures suggesting that failures in the landlordtenant relationship in the private-rented sector are a key barrier to uptake. More broadly, we find that it is the characteristics of the dwelling rather than those of the occupants which are the most significant explanatory factors. Our results suggest that well-targeted policies to encourage take-up of efficiency measures could focus on private landlords, long-term owner occupiers, those in older properties and those using non-metered fuels as their main heating source. However the key target groups vary across different efficiency measures. Terms of use: Documents in
