Limit My Energy Use! An In-Situ Exploration of a Smart Home System Featuring an Adaptive Energy Threshold
- 2019
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- The ongoing increase of ‘smart’ home technologies could facilitate for households to shift energy demand to contribute to balancing increasingly fluctuating energy supply from renewable sources. Yet, although many smart home technologies support energy saving, few of the commercially available smart home systems actually facilitate demand shifting and instead highlight other features, such as home security or convenience. The study presented here aimed (i) designing a smart energy system that enables balancing energy demand and supply and (ii) exploring what happens when households are equipped with such a smart home system. In the system developed, called Ero, households’ energy use is related to the status of the energy system through a momentary power threshold and users can match their use of energy-reliant appliances to the threshold. Findings showed that a majority of the participants, in different ways, started to relate their energy use to the status of the energy system. Most of them appreciated the idea of having an energy threshold and some wanted stricter energy limitations. Yet, as the participants lived in small apartments and controlled a limited number of energy-reliant appliances only a few of them were able to make Ero an integrated part of everyday activities. Further, many of them questioned the extent to which their demand-shifting could contribute as their energy-reliant appliances were thought to not use much energy. Instead, the participants considered other paths towards a more sustainable energy system to be important, such as influencing decisions made by companies, politicians, and non-governmental organisations. The problem was however that Ero did not provide any support for how to influence beyond the individual household. To conclude, an energy focused smart home system can facilitate shifting energy demand and would be relevant for homes controlling bigger loads, such as electric vehicles or washing machines. Yet, such smart home systems cannot be considered a necessity in the quest for a more sustainable energy future.

Konferensbidrag (refereegranskat)abstract
- To reduce the environmental impact of the use phase of products, researchers have suggested applying design strategies for sustainable behaviour. The aim of this study was to evaluate four different design strategies on the basis of longterm acceptability and effectiveness in inducing sustainable behaviours. A literature review was carried out and a model for categorisation of strategies was created containing five categories: Enlighten, Spur, Steer, Force and Match. Four design strategies for sustainable behaviour, belonging to the first four categories, were implemented in prototypes to achieve moderate dosing of washing detergent. The prototypes were distributed to 16 households and a between subject study design was applied. The results indicate that three of the four strategies for many households were both effective and accepted. This suggests that product design can be a feasible way to induce and maintain sustainable behaviour.

Konferensbidrag (refereegranskat)abstract
- The research field of Design for Sustainable Behaviour (DfSB) suggests strategies for promoting more sustainable use of products. The DfSB methodology thus provides opportunities for companies to further reduce their products’ environmental impact and differentiate on the market, still DfSB is not yet systematically applied in industry. This paper highlights benefits and difficulties that companies face when applying design strategies for sustainable behaviour in the product development process. A master thesis project at Electrolux is used as a basis for discussion. In summary, besides the environmental gains, DfSB can spur innovations that fit users’ implicit needs and thus create potential for increased profitability. Nevertheless, companies need to extend their competence within DfSB and methodologies that facilitate the implementation of DfSB in companies’ current product development processes should be developed.

Konferensbidrag (refereegranskat)abstract
- What are the effects and perceptions of increased installation of water metering and volumetric billing in residential areas in Sweden? An interview study was undertaken in a low-income suburb of Göteborg to explore residents’ experiences and opinions. Additionally, the interests of water and energy companies, social affairs committee, real estate owner and maintainer were investigated to contrast the added value of reduced water consumption. Stakeholders either benefit or are disadvantaged by the introduced system. Furthermore, the applied tariff structure fails to motivate all segments of the population to reduce water consumption, yet still inequitably burdens the most financially exposed groups.

Participating in Energy Systems through Everyday Designs – Exploring roles for households in a more sustainable energy future
- 2019
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- As households we participate in energy systems when, in the course of our everyday energy-reliant activities, we create a demand for energy and when we engage in energy-managing activities such as choosing an energy provider and deciding to support a specific source of energy. In this way, everyday life has an impact on the energy sector, and vice versa. To mitigate climate change, the energy sector will have to reduce its negative environmental impact, and everyday life will have to change with it. This thesis aims at contributing to development of artefacts that, as they are embedded into energy-reliant and energy-managing activities in everyday life, support such changes. Four empirical studies were carried out in a research through design process with a ‘mixed methods’ approach. Two studies described which energy-reliant and energy-managing activities to design for by identifying what roles households could play in energy systems (RQ 1a). Two studies explored how artefacts shape those roles (RQ 1a) and prescribed ways to design to support reduced negative environmental impact (RQ 2). The findings showed that the roles households considered playing in energy systems were framed by (i) roles performed by peers, (ii) available and accessible energy-reliant and energy-managing artefacts, (iii) existing business models, (iv) available infrastructure, and (v) policy and regulation. The roles were framed into three so-called meta-roles named Reception, Interplay, and Balance. Within Reception , households receive standardised amounts and variants of services from the energy system, such as a pre-set indoor temperature. Within Interplay , the households’ meta-role is to use some kind of interplay with the energy system to optimise energy services for their individual preferences, for example low cost. Finally, within Balance , the households’ meta-role is to balance their individual preferences with what is preferable from an energy system perspective, for instance without benefits to be part of time-shifting energy use to cut peaks in demand. In Reception and Interplay, the reduction in environmental impact is restricted to either what can be achieved without households’ active contribution or when reductions in environmental impact align with personal preferences, respectively. Balance, although uncommon and therefore unvalidated, was therefore considered most promising to mitigate climate change. Evaluations of two prototypes intended to support reduced negative energy-related environmental impact showed such possibilities, and additionally that Reception and Interplay could be challenged by designing artefacts that: - encourage households to make compromises and ask for efforts; - make the connection between energy supply and demand explicit (reconnecting supply and demand); - provide a possibility to feel like active participants (instead of discouraging active participation through automation); - provide a possibility for influencing energy-related decisions made by energy companies or (local) authorities; and - focus on energy-reliant activities and not (only) on energy-managing activities. Artefacts are however just one of the five aspects found to frame meta-roles. In order to not only challenge but also change a prevailing meta-role, the other aspects would need to align.

Konferensbidrag (refereegranskat)abstract
- One approach to further decrease the environmental impact of products is to target the use phase. According to the Design for Sustainable Behaviour approach different design strategies can be used to enable a more sustainable use of products by influencing the user’s behaviour. The strategies suggested include matching products to users’ current behaviours, enlightening users, spurring or steering theusers towards more sustainable behaviours, and applying a force dimension to the products. Empirical studies demonstrate the feasibility of different strategies.However further knowledge is needed on which strategies to apply in which situations and for what problems.
