The world keeps changing more rapidly. Induced by context change disruptions such as individual life-course changes and macro socio-economical events, the way people carry out their everyday life doings is also undergoing a dynamic transition process, which may open up windows of opportunity for design to transit people's behavior in a more sustainable direction. A successful behavior transition entails not only changing people's wrongdoings but also retaining the existing desired doings. However, over the last decade, the field of Design for Sustainable Everyday Life seems to have grown accustomed to the concept of change. The potential role that design may play in retaining people's existing sustainable doings has been ill-addressed. This dissertation aims to develop an activity-based theoretical approach to help design researchers and practitioners better understand how people transit behavior when they undergo context change disruptions, and further explore design implications informed by the sustainable behavior retention perspective. The study comprises two parts. In the first part, six explorative case studies were used to investigate the applicability of adopting activity theory (AT) as a theoretical lens for understanding context change-induced behavior transition phenomena. As a result, an ATbased framework was iterated, developed and validated. In the second part, by incorporating the proposed framework with the theoretical understanding generated from a prescriptive meta-synthesis study, an AT-informed toolkit prototype was developed and evaluated. Three key findings can be identified. First, at a conceptual level, the study reveals that the design for sustainable behavior retention perspective may complement the design for behavior change perspective by facilitating a bottom-up and context-focused relative approach to achieve sustainability. Second, at a design analytical level, three dimensions of AT: i). hierarchical structure, ii). long-term development and iii). reality-based contextual scales of analysis are especially useful for systematically analyzing the impacts of context change disruptions on people's everyday life doings. Third, at a design synthesis level, the ATinformed design toolkit prototype and the extracted design implications can provide a systemic view that helps designers take both sustainable behavior change and retention perspectives into early-stage design ideation. The contribution of the dissertation is two folds. First, it introduces the perspective of sustainable behavior retention into the field of Design for Sustainable Everyday Life. Second, it provides an activity-based theoretical framework as a potential lens for designers to better cope with context change disruptions.

“…It has also been observed that the ship's crew usually have a direct and considerable impact on EE through their operational practices [3,8,9]. For example, as punctuality is critical for ferry vessels, the crew need to find the proper balance between fuel consumption at lower speeds and the direct and indirect costs of delayed port arrival [3].…”

From Ethnographic Research to Big Data Analytics—A Case of Maritime Energy-Efficiency Optimization

The shipping industry constantly strives to achieve efficient use of energy during sea voyages. Previous research that can take advantages of both ethnographic studies and big data analytics to understand factors contributing to fuel consumption and seek solutions to support decision making is rather scarce. This paper first employed ethnographic research regarding the use of a commercially available fuel-monitoring system. This was to contextualize the real challenges on ships and informed the need of taking a big data approach to achieve energy efficiency (EE). Then this study constructed two machine-learning models based on the recorded voyage data of five different ferries over a one-year period. The evaluation showed that the models generalize well on different training data sets and model outputs indicated a potential for better performance than the existing commercial EE system. How this predictive-analytical approach could potentially impact the design of decision support navigational systems and management practices was also discussed. It is hoped that this interdisciplinary research could provide some enlightenment for a richer methodological framework in future maritime energy research.

“…Numerous factors thus influence the fuel consumption of a ship, which often varies significantly during and between voyages. This complexity, including the lack of knowledge on the ship and route specificity of energy consumption, makes it particularly difficult for crews to learn and develop optimal work practices (Rasmussen et al 2018;Viktorelius and Lundh 2019). Implementation and use of information technology to monitor energy use is thus critical for efficient operations.…”

The paper offers an analysis of how an energy-monitoring system was implemented and eventually adopted by the crew members in a shipping company. It illustrates how the social process of enacting the system as a collaborative technologyin-practice, enabling a significant reduction in energy consumption, was contingent on the negotiation of meaning and mutual learning among crew members in their community of practice. The case study contributes to the literature on the relation between information technology, organization and energy efficiency by investigating the socially situated nature of technology implementation and work practice change. The findings' implications for the role of information technology in improving energy efficiency in shipping are discussed.
