Understanding cooking behaviours to design energy saving interventions
People’s behaviours play an important role in energy consumption, especially whilst dealing with high consumption, highly interactive appliances such as cookers. In a user observation study conducted among university students, participants were asked to perform a simple cooking task. Their behaviours were analysed and compared with a set of recommended practices. The electricity usage and time to complete the activity were also measured. The results show that participants performed in several different ways, presenting diverse energy usage. The determinants of these behaviours were also collected, and will help to inform the design of interventions to motivate people to change their behaviours whilst cooking.
Cooking behaviours: a user observation study to understand energy use and motivate savings
2012
Electric cookers are one of the highest energy consuming domestic appliances, and there are several aspects that can influence the amount of energy used when preparing a meal. Appliance characteristics are shown to influence consumption, but human factors play an important role in the overall electricity usage. A user observation study was conducted among university students to understand how they use electric cookers. They were asked to perform a specific cooking task, and the electricity usage was measured. Participants' behaviours were analysed and compared with a set of energy saving techniques. Appliance characteristics that influenced how students use energy were also investigated. The results show that users performed the task in several different ways, presenting diverse energy consumption, the average being 3 times above the necessary to complete the task. This information is now informing the design of interventions to motivate people to change their behaviours whilst cooking.
User's Influence on Energy Consumption with Cooking Systems Using Electricity
The research purpose was to explain the user's influence on energy consumption with cooking systems using electricity. This research was conducted in two phases. The research objective of Phase I was to determine if relationships exist that explain the user's influence (i.e., user characteristics--knowledge, experience, practices, and user interaction--and appliance operating time) on the energy consumption of cooking systems using electricity. The ultimate aim of this research, the outcome of Phase II, was to identify categories of cooking style that explain the user's influence (i.e., user characteristics and appliance operating time) on energy consumption of cooking systems using electricity.

Inhabitants use energy to perform various activities of daily life in the private sphere i.e. the household scope. The activities they undertake are stochastic in nature and difficult to predict. Moreover there is a significant difference between real and theoretical uses of eco-designed products. It is therefore necessary to address the issue of measuring the real energy consumption of the inhabitants in order to identify their behaviour and decrease their environmental impact. In this paper we present an experimental study focusing on kitchen perimeter and cooking activity with two objectives: (1) ordering 20 advices to send to people by considering the perceived difficulty of practicing them and (2) identification of practice difficulties of eco-gestures by experience feedback. The aims are to get design inputs by increasing the difficulty of the activity and to identify needs related to a "weak" product design and consequently a user need to (re)design products for sus...
Dynamic energy-consumption indicators for domestic appliances: environment, behaviour and design
Energy and Buildings, 2003
The literature concerning the application of information-feedback methods for saving energy in the home is reviewed. Particular attention is given to electronic feedback via smart meters and displays, or ''energy-consumption indicators'' (ECI). Previous studies have not focused on individual appliances, but this paper presents the findings of a UK field study involving 44 households which considered domestic cooking: it compares the effectiveness of providing paper-based energy-use/saving information with electronic feedback of energy-consumption via ECIs designed specifically for this investigation. Twelve Control Group households were monitored for a period of at least 12 months and this revealed an average daily consumption for electric cooking of 1.30 kWh. Subsequently across a minimum monitoring period of 2 months, 14 out of 31 households achieved energy savings of greater than 10% and six of these achieved savings of greater than 20%. The average reduction for households employing an ECI was 15%, whereas those given antecedent information alone reduced their electricity consumption, on average, by only 3%. The associated behavioural changes and the importance of providing regular feedback during use are identified. It is recommended that further attention be given to optimising the design and assessing the use of energy-consumption indicators in the home, in order to maximise the associated energy-saving potential.
Energy consumption in UK households: Impact of domestic electrical appliances
Applied Energy, 1996
The social-psychological aspects of energy use in UK households have been reviewed. A major survey, which,focused on identtxving environmental attitudes and beliefs, energy-use hehaviour, ownership levels,for certain appliances and their utilisation patterns, \t'as undertaken among householders resident in the southeast of England. The results indicute that members of the general public are li) interested in receiving informution concerning household energyuse and the associated environmental impuct, and (ii) willing to modify' their hehaviour in order to reduce household energy consumption und environmental damage. Therefore, there is un urgent need to provide end-users with accurate energy-consumption und environmental-impact information. persuasively presented, to stimulute energy-rational and environmentally~ sustainable behaviour. For each mujor domestic electrical appliance, the survey data permit estimates of the variations in energy consumption per household and of the aggregate annual consumption nationally. Copyright
People and Energy: A design-led approach to understanding everyday energy use behaviour
Ethnographic Praxis in Industry Conference Proceedings, 2013
Reducing home energy use is a major societal challenge, involving behaviour change alongside infrastructure improvements. However, many approaches lump 'energy demand' together as something homogeneous, addressable primarily through quantitative feedback, rather than basing interventions on an understanding of why people use energy as they do. Our contention is that people don't set out to 'use energy': its use is a side effect of solving everyday problems, meeting needs for comfort, light, cooking, cleaning, entertainment, and so on.

About SEI Working Papers: The SEI working paper series aims to expand and accelerate the availability of our research, stimulate discussion, and elicit feedback. SEI working papers are work in progress and typically contain preliminary research, analysis, findings, and recommendations. Many SEI working papers are drafts that will be subsequently revised for a refereed journal or book. Other papers share timely and innovative knowledge that we consider valuable and policyrelevant, but which may not be intended for later publication.

The Modern Energy Cooking Services (MECS) programme has generated data on the amount of energy required to cook meals using different fuels and cooking devices. Fuel stacking is commonplace, especially among households with access to modern fuels. Experience shows that people tend to use modern fuels for quick tasks, such as preparing a cup of tea, but prefer to use biomass fuels for foods that take longer to cook. Therefore, changes in the choice of foods in the household menu have the potential to affect the transition to modern fuels. This paper discusses the potential of innovative and emerging aspects of food systems in low-income countries to impact on households. It starts by looking at the processing of indigenous crops to create convenient and nutritious food products. This leads to an overview of the rapid growth of the food processing industry and future opportunities. Consuming food that has been prepared outside of the home is also a common and rapidly growing practice,...
