Given the project’s focus on customer behaviour change, it has commenced with a thorough review of customer engagement in both the energy sector and wider industries, in the UK and internationally, to evaluate which measures have been most effective in terms of motivating behavioural change and which have worked less well. This should ensure that the project can build on previous learning in the field and not repeat previous mistakes. The findings from projects reviewed have been analysed through the Cabinet Office ‘MINDSPACE’ framework that provides a guideline for policies that aim to change behaviour. The project has adapted this framework to use it as a guidline to analyse lessons learned from past reasearch. The trial design for the SAVE project will also use the MINDSPACE framework to help structure the measures it takes. This report begins by explaining the MINDSPACE framework and the methodology for this project review.` Although findings from the projects reviewed are at times contradictory, and the great variety of trial approaches and contexts often makes it difficult to compare their different results, some trends have emerged. These trends are summarised in section 3 into eleven key findings as follows: 1. Customer segmentations should actively assist in targeting campaigns effectively by focusing on differences in energy use, personal values and preferred methods of communication. Customers connected to the electricity distribution network cannot be engaged with as one group; the way in which people react to attempts to change their energy behaviour differs and engagement needs to be tailored appropriately without resulting in prohibitative costs. 2. Customers need to understand how they can reduce their energy usage and be educated appropriately. These can be through a combination of physical equipment, information and advice. 3. Parties delivering messages to customers need to be seen and recognised as both trustworthy and authorities in the subject matter. These attributes are not necessarily found in one entity and partnership between energy companies and trusted groups such as local organisations and community groups can be a way of overcoming this difficulty. Also effective is to allow multiple organisations to deliver messages that are consistent on a theme yet approached from their different perspectives. 4. Financial incentives can be effective but potentially need to be relatively large and impacts are often not sustainable over time; non-financial incentives should also be considered. 5. Normative comparisons between households have been shown to be very successful when based on intelligent like-for-like comparisons and combined with effective messaging. 6. Opt-out designs should be applied where possible as they are typically more effective than opt-in approaches, for example if offering energy advice visits or competitions. 7. Novel and creative techniques for sharing information can be used to effectively capture customer attention. 8. There is a delicate balance to be struck between using negative concepts such as ‘waste’ or ‘loss’ while also making customers feel good about themselves. 9. Customer commitments through setting goals and targets can be very effective to achieve longer-term behaviour change, but often need strong incentives to give them meaning. 10. Leading by example in promoting energy efficiency improves the perception of customers and increases the credibility of the project and its communications. 11. Energy efficiency results need to be analysed within the context of wider factors such as the wider economic and regional context, the number of participants and the level of focus on peak demand. DNV GL – Report No. 1.0, Rev. 1.1 – www.dnvgl.com Page 1 The report goes on to describe the projects reviewed through the MINDSPACE framework describing how projects have used different aspects of the framework and the levels of success they have demonstrated. This includes specific reviews of projects from non-energy sectors, in particular focusing on particularly interesting and creative ways that behaviour change has been successfully achieved, as well as those LCNF projects where domestic customer engagement has taken place. Through creating this report we have found that although many energy efficiency projects have been carried out and have delivered some interesting findings, there is still much more to do to achieve a comprehensive understanding of how different measures affect different types of consumers in different ways and in different scenarios. Many trials have found a core group or customer segment whose behaviour is very difficult to change. Successful ways of engaging with this segment, which tends to be the largest single group, would add significantly to the knowledge base in this area. In order to be effective, approaches will need to draw on successful approaches, perhaps outside the energy sector and trial novel ways of encouraging change. The SAVE project will use the findings from this report to design trials that will add to the knowledge base on energy behavioural change and push existing knowledge further.
