Abstract [en]

Cites have been identified as one key arena to meet future sustainability challenges. However, if cites are to be part of the transition it must become possible to confirm results of ongoing actions. By the introduction information and communication technologies, it has become easier to collect performance parameters from the built environment, thereby enable more detailed evaluation. The aim of this paper is therefore to examine the potential and limitation of using dynamic and high resolution meter data for evaluation of energy consumption in buildings and households. The novelty of this approach is that dynamic and high resolution meter data can increase the level of detail in evaluation results and ease detection of deviations in the structures performance. However, most benefits are found from the occupant perspective, as more detailed evaluation information enable better inclusion of this stakeholder group. Furthermore this study has shown that the commonly used indicator energy use per heated floor area is an insufficient communication tool when taking holistic approach to building energy evaluation. Limitation to full use of dynamic and high resolution meter data have been identified to data collection and management, preservation of personal integrity and incentives to react on the given evaluation information.

Abstract [en]

Real-time energy feedback (EF) and demand response using dynamic pricing tariffs (DR) have been suggested as effective intervention strategies to meet the need for increased energy efficiency and demand flexibility in the residential sector. Although previous studies provide some empirical support for the effectiveness of EF and DR, evaluation approaches used in practical experiments and field trials commonly suffer from several methodological shortcomings, preventing deeper of knowledge on the potential and barriers for EF and DR to influence household energy consumption.

This thesis explored the potential of employing a mixed methods approach for evaluation of household energy consumption to provide improved understanding on how and why households engage and respond to EF and DR strategies. Three research objectives were set: 1) Analysis of the potential for using high-resolution data from smart meters in evaluation of household energy consumption and response to DR strategies, 2) development of a conceptual framework for evaluation of household responses to EF and DR strategies and analysis of its potential to increase understanding of household responsiveness, and 3) identification and analysis of household motivations, perceptions, and obstacles to engaging in EF and DR strategies.

The work to achieve these objectives followed a mixed methods research methodology grounded on literature reviews and empirical studies in real-life settings in a single case study, an EF/DR field trial taking place in Stockholm Royal Seaport. A combination of quantitative and qualitative methods was used for data collection and analysis, comprising interviews, surveys, and statistical analysis of smart meter energy data.

The results suggest that the mixed methods approach addresses several of the limitations and challenges associated with previous evaluation approaches. As regards objective (1), it was found that high-resolution data from smart energy meters can provide evaluation outcomes with increased transparency and accuracy. Regarding objective (2), it was found that the proposed framework can increase understanding of variations in household responsiveness to EF and DR strategies and reveal the relationship between impacts on electricity use and factors influencing energy consumption behavior. As regards objective (3), several obstacles for households to engaging in EF and DR strategies were identified, primarily related to household-individual factors such as knowledge, sense of control, and personal values and attitudes. Based on these findings, key issues and areas for further research are proposed.

2018 (English)Doctoral thesis, comprehensive summary (Other academic)
Abstract [en]

Urban sustainable development is now seen as one of the keys in the quest for a sustainable world and increased interest in developing sustainable urban districts has become an important feature of urban sustainability. However, if cities and their districts are to be part of this transition, it will be necessary to determine the state and progress of urban developments. Evaluation and follow-up activities must therefore be an integral part of modern sustainability work.

This thesis investigated evaluation methods and strategies for determining progress towards sustainable urban district development. The Stockholm Royal Seaport district in Sweden was used as the research arena in studies based on urban metabolism theories, including a single case study approach, focus group interviews, the Framework for Strategic Sustainable Development and quantitative data analysis. The thesis main results can be summarised as follows.

A structured frame for use in theory and practice can strengthen programme development and minimise the risk of built-in problems in environmental and sustainability plans for new urban districts. The proposed evaluation model for Stockholm Royal Seaport displayed strengths regarding core evaluation activities, such as communicating a strong vision and recognising continuity in the evaluation process. It displayed weaknesses as regards organisational structure and system boundaries.

 The proof-of-concept implementation of a Smart Urban Metabolism framework enabled real-time evaluation data on district scale to be generated and processed. The implementation process also led to identification of limitations in the framework, such as access to business sensitive data, failed integration of data streams and privacy concerns. Dynamic, high-resolution meter data can provide a higher degree of transparency in evaluation results and permit inclusion of all stakeholder groups in urban districts. The frequently used energy performance indicator kWh/m2 (Atemp) was shown to be an insufficient communication tool to mediate knowledge, due to conflation of consumption and construction parameters and the need for prior knowledge for full understanding.

Abstract [en]

In order to reach the current climate goals, energy consumption needs to decrease in all sectors, including households, which produce 20% of the European emissions. However, it is difficult to increase residents’ engagement in their household electricity consumption as it is an ‘invisible’ form of energy, the monetary incentives are often too small and environmental incentives are not very effective. Building on the idea that an engagement mechanism should be based on user needs, and recent research showing that social influence can be an effective way to affect consumption behaviour, this thesis examines the potential of a neighbourhood-based digital local social network providing feedback on household electricity consumption as an engagement solution. By helping neighbours to know each other better, such a network could meet the basic human need of belonging to a group, while also taking advantage of the social influence between neighbours to increase the effectiveness of the energy feedback provided.

This thesis sought to: 1) Identify needs of residents that could be served by a local social network and explore whether such a network could provide a beneficial context for energy feedback; 2) identify and evaluate a set of design principles for energy feedback and use them to propose a prototype feedback design suitable for use in a local social network; and 3) design and implement a baseline study for measuring changes in aspects of social and environmental sustainability in a neighbourhood that introduction of a local social network can achieve, such as social cohesion, trust, safety, and energy attitudes and behaviour.

In order to achieve these objectives, the Research Through Design methodology was used. This resulted in mixed methods research using quantitative (household survey) and qualitative (focus group interviews, stakeholder consultation workshop) methods. The research was conducted in two eco-districts in Stockholm, Sweden: Hammarby Sjöstad and Stockholm Royal Seaport.

Regarding the first objective, results from the household survey indicated a need for increased interaction between neighbours in Stockholm Royal Seaport, while the focus group discussions revealed local communication needs that a local social network could meet. However, the possibility to use social influence between neighbours in increasing the intention to save energy was shown to be rather weak, possibly because of the current low level of connection between neighbours. Regarding the second objective, a set of design principles was identified using a literature study. They were used to create a design prototype of energy feedback that was presented to potential end-users in a stakeholder consultation workshop and then refined using suggestions given in the workshop. The workshop indicated support for many of the design principles as they were indirectly mentioned in the discussions. The design principle of fair feedback was further explored, suggesting use of typical household consumption as part of a fair comparison metric and when setting reduction goals.

Regarding the third objective, an evaluation method with baseline survey and follow-up surveys was suggested. The household survey served as a baseline for measuring social and environmental sustainability aspects in a neighbourhood. Further research is needed on the effectiveness of a local social network as an engagement mechanism for energy feedback.

Abstract [sv]

För att nå de nuvarande klimatmålen måste energiförbrukningen minska i alla sektorer, även för hushåll som står för 20% av de europeiska utsläppen. Det är dock svårt att öka medborgarnas engagemang kring förbrukningen av hushållsel då el är en "osynlig" energiform, de monetära incitamenten ofta är ofta för små och miljöincitament inte är särskilt effektiva. Baserat på idén att en engagemangsmekanism bör baseras på användarbehov samt ny forskning som visat att socialt inflytande kan vara ett effektivt sätt att påverka konsumtionsbeteendet, undersöker denna avhandling potentialen i ett grannskapsbaserat digitalt lokalt socialt nätverk som tillhandahåller feedback på hushållens elförbrukning som en engagemangslösning. Genom att hjälpa grannar att lära känna varandra bättre kan ett sådant nätverk uppfylla det grundläggande mänskliga behovet av att tillhöra en grupp, samtidigt som det sociala inflytandet mellan grannar kan utnyttjas för att öka effektiviteten hos den tillhandahållna energiåterkopplingen.

Denna avhandling hade tre mål: 1) Identifiera behov hos boende som kan tillgodoses av ett lokalt socialt nätverk samt undersöka huruvida ett sådant nätverk skulle kunna tillhandahålla en bra kontext för energiåterkoppling, 2) identifiera och utvärdera en uppsättning designprinciper för energiåterkoppling, och använda principerna för att föreslå en prototypdesign för energiåterkoppling lämplig för användning i ett lokalt socialt nätverk och 3) utforma och genomföraen baseline-studie för att mäta förändringar i aspekter av social och miljömässig hållbarhet i ett grannskap skulle kunna främjas av införandet av ett lokalt socialt nätverk, exempelvis social sammanhållning, tillit, säkerhet samt energiattityder och beteende.

För att uppnå dessa mål användes Research Through Design-metodiken, vilket i sin tur resulterade i en s.k. “mixed methods”-forskningsmetodik där både kvantitativa (hushållsundersökning) och kvalitativa (fokusgruppintervjuer, workshop) metoder användes. Forskningen genomfördes i två distrikt med miljöprofil i Stockholm: Hammarby Sjöstad och Norra Djurgårdsstaden.

Beträffande det första målet indikerade hushållsundersökningen ett behov av ett ökat samspel mellan grannarna i Norra Djurgårdsstaden. Fokusgruppdiskussionerna avslöjade lokala kommunikationsbehov som ett lokalt socialt nätverk skulle kunna möta. Möjligheten att använda socialt viiinflytande mellan grannar för att öka intentionen att spara energi visade sig dock vara ganska liten, möjligen på grund av den nuvarande låga nivån av sammanhållning mellan grannarna. Beträffande det andra målet identifierades en uppsättning designprinciper med hjälp av en litteraturstudie. Dessa användes för att skapa en designprototyp på energiåterkoppling som presenterades till potentiella slutanvändare under en workshop. Prototypen förbättrades sedan med hjälp av de förslag som gavs i workshopen. Workshopen gav också stöd åt många av designprinciperna som indirekt nämndes under diskussionerna. Designprincipen för rättvis återkoppling undersöktes ytterligare vilket ledde till ett förslag om att använda typisk hushållskonsumtion som en del av en rättvis jämförelseindikator och vid fastställning av energisparmål.

Beträffande det tredje målet föreslogs en utvärderingsmetod baserat på en baseline-studie och uppföljande studier. Hushållsundersökningen fungerade som en utgångspunkt för mätning av sociala och miljömässiga hållbarhetsaspekter i ett grannskap. Ytterligare forskning föreslogs för att visa på effektiviteten hos ett lokalt socialt nätverk som en engagemangsmekanism för energiåterkoppling.
