Evidences of lay people’s reasoning related to climate change: per country and cross country results

This deliverable is about lay citizens’ reasoning about sustainability, in particular environmental protection and climate change, in various consumption domains, and the relation of this reasoning to the day-to-day lives of the participants. It presents country and cross-country findings from all 18 STAVE trials conducted between May 2011 and February 2012 in all six PACHELBEL partner countries. Analyses demonstrate that participants in the STAVE trials predominantly display a clear awareness that citizen consumption as demonstrated in their everyday practices of energy use, mobility, waste etc. are strongly connected with issues of environmental sustainablility. The STAVE trials also demonstrated that to live sustainably is a daily challenge, and people are often not able to organize their everyday routines in an environmental-friendly manner. Frequently there is a gap between participants’ aspirations and their practical behaviours. Significantly, the group conversations enabled participants to become aware that the self-assessed soundness of their everyday lives in terms of sustainability was at variance from the actual impact of e.g. their energy use or or mobility practices

Coffee maker patterns and the design of energy feedback artefacts

Smart electricity meters and home displays are being installed in people’s homes with the assumption that households will make the necessary efforts to reduce their electricity consumption. However, present solutions do not sufficiently account for the social implications of design. There is a potential for greater savings if we can better understand how such designs affect behaviour. In this paper, we describe our design of an energy awareness artefact – the Energy AWARE Clock – and discuss it in relation to behavioural processes in the home. A user study is carried out to study the deployment of the prototype in real domestic contexts for three months. Results indicate that the Energy AWARE Clock played a significant role in drawing households’ attention to their electricity use. It became a natural part of the household and conceptions of electricity became naturalized into informants’ everyday language

Making Heat Visible: Promoting Energy Conservation Behaviors Through Thermal Imaging

Householders play a role in energy conservation through the decisions they make about purchases and installations such as insulation, and through their habitual behavior. The present U.K. study investigated the effect of thermal imaging technology on energy conservation, by measuring the behavioral effect after householders viewed images of heat escaping from or cold air entering their homes. In Study 1 (n = 43), householders who received a thermal image reduced their energy use at a 1-year follow-up, whereas householders who received a carbon footprint audit and a non-intervention control demonstrated no change. In Study 2 (n = 87), householders were nearly 5 times more likely to install draught proofing measures after seeing a thermal image. The effect was especially pronounced for actions that addressed an issue visible in the images. Findings indicate that using thermal imaging to make heat loss visible can promote energy conservation

Turning Up the Heat on Energy Monitoring in the Home

The use of domestic electrical energy monitoring systems is becoming more common however gas usage has received comparatively little attention. This paper presents a new technique for monitoring gas-powered heating and hot water usage in the home integrated into a prototype energy monitoring platform. Compared to usual meter-based approaches this technique provides finer-grained usage data and uses simple temperature sensors. The main motivation for this work is to provide more meaningful energy information to users for inclusion in novel mobile and embedded applications. This is part of ongoing work which aims to reduce energy use among teenagers in the UK and make lasting attitude changes. The development and findings from a prototype deployed in a typical UK house over 7 days are presented. The findings highlight the utility of the technique and simplicity of the sensing approach. The novel requirements that inspired the development of this technique are also presented

Exploring the role of marketing as a tool to aid smart meter adoption amongst fuel poverty and vulnerable groups

This study is concerned with exploring the role of marketing as a tool to improve smart meter adoption amongst different fuel poverty groups. The traditional view of marketing is that it is a process by which people and firms get what they require and desire by generating and trading value with others (Kotler and Armstrong, 2010). Nonetheless, a more recent view of marketing is that it provides a vehicle to aid the achievement of a wide range of social goals. In this instance, fuel poverty and energy efficiency. For example, social marketing could be used as a means of ‘engaging’ fuel poverty groups to improve the energy efficiency of their home. Despite this, few empirical studies have explored the role of marketing in alleviating fuel poverty and improving energy efficiency

Review of UK microgeneration. Part 1 : policy and behavioural aspects

A critical review of the literature relating to government policy and behavioural aspects relevant to the uptake and application of microgeneration in the UK is presented. Given the current policy context aspiring to zero-carbon new homes by 2016 and a variety of minimum standards and financial policy instruments supporting microgeneration in existing dwellings, it appears that this class of technologies could make a significant contribution to UK energy supply and low-carbon buildings in the future. Indeed, achievement of a reduction in greenhouse gas emissions by 80% (the UK government's 2050 target) for the residential sector may entail substantial deployment of microgeneration. Realisation of the large potential market for microgeneration relies on a variety of inter-related factors such as microeconomics, behavioural aspects, the structure of supporting policy instruments and well-informed technology development. This article explores these issues in terms of current and proposed policy instruments in the UK. Behavioural aspects associated with both initial uptake of the technology and after purchase are also considered

Competition and norms: a self-defeating combination?

This paper investigates the effects of information feedback mechanisms on electricity and heating usage at a student hall of residence in London. In a randomised control trial, we formulate different treatments such as feedback information and norms, as well as prize competition among subjects. We show that information and norms lead to a sharp – more than 20% - reduction in overall energy consumption. Because participants do not pay for their energy consumption this response cannot be driven by cost saving incentives. Interestingly, when combining feedback and norms with a prize competition for achieving low energy consumption, the reduction effect – while present initially – disappears in the long run. This could suggest that external rewards reduce and even destroy intrinsic motivation to change behaviour

Power and energy visualization for the micro-management of household electricity consumption

The paper describes a pilot system for the detailed management of domestic electricity consumption aimed at minimizing demand peaks and consumer cost. Management decisions are made both interactively by consumers themselves, and where practical, automatically by computer. These decisions are based on realtime pricing and availability information, as well as current and historic usage data. The benefits of the energy strategies implied by such a system are elaborated, showing the potential for significant peak demand reduction and slowing of the need for growth in generation capacity. An overview is provided of the component technologies and interaction methods we have designed, but the paper focuses on the communication of real-time information to the consumer through a combination of specific and ambient visualizations. There is a need for both overview information (eg how much power is being used right now; how much energy have we used so far today; what does it cost?) and information at the point-of-use (is it OK to turn this dryer on now, or should I wait until later?). To assist the design of these visualizations, a survey is underway aimed at establishing people's understanding of power and energy concepts

Fostering energy awareness in residential homes using mobile devices

There is considerable global effort being made towards identifying ways of reducing energy consumption to cope with growing demands. Although there is potential for energy saving in many sectors, our focus is on reducing energy consumption in residential homes. We have developed a system which combines home automation and energy usage monitoring technologies. The system offers a range of tools designed for mobile devices to assist users with monitoring their energy usage and provides mechanisms for setting up and controlling home appliances to conserve energy. In this paper we describe our system and a user study we have conducted to evaluate its effectiveness. The findings of the study show the potential benefits of this type of mobile technology

Analysis of a residential building energy consumption as “base model” in Tripoli, Lebanon

The interest in energy performance of buildings in Lebanon has increased in the last few years. Indeed, many organizations are evaluating the commercial buildings’ energy performance in order to increase the commercial sector energy efficiency. Since residential buildings occupy 47% of the overall end-use energy consumption in Lebanon, therefore; the development of a rating methodology for residential energy performance should also be significant. This study reveals the results of a field survey of residential apartment buildings in the city of Tripoli. The survey focuses on the newly built-up extended zones of the city (Basateen El-Mina and Basateen Trablous), that are subject to the current building code. Based on a questionnaire and a monitoring survey, a building performance simulation model was created to reflect the average energy consumption characteristics for the most residential building accumulation. This benchmark model describes the energy use report for heating, cooling, lighting, domestic hot water systems and appliances with respect to the building’s layout, orientation and construction. The output data of the simulation will be compared with collected EDL (Electicite du Liban) bill. The aim of this study is to develop representative building energy data sets and benchmark models for the Lebanese residential sector specifically in the coastal zone area. Having a “base model “as a benchmark for existing residential buildings will form the basis of a research on specific building technologies and measurements of progress towards the Zero Energy Building goal
