Abstract [en]

Today's commercially-off-the-shelf (COST) wearable devices can unobtrusively capture several important parameters that may be used to measure the indoor comfort of building occupants, including ambient air temperature, relative humidity, skin temperature, perspiration rate, and heart rate. These data could be used not only for improving personal wellbeing, but for adjusting a better indoor environment condition. In this study, we have focused specifically on the sleeping phase. The main purpose of this work was to use the data from wearable devices and smart meters to improve the sleep quality of residents living at KTH Live-in-Lab. The wearable device we used was the OURA ring which specializes in sleep monitoring. In general, the data quality showed good potential for the modelling phase. For the modelling phase, we had to make some choices, such as the programming language and the AI algorithm, that was the best fit for our project. First, it aims to make personal physiological data related studies more transparent. Secondly, the tenants will have a better sleep quality in their everyday life if they have an accurate prediction of the sleeping scores and ability to adjust the built environment. Additionally, using knowledge about end users can help the building owners to design better building systems and services related to the end-user's wellbeing.

Abstract [en]

The main goal of this thesis is to communicate the motivation, process, and result of the research project dedicated to exploring the topic of Service Design, based on end-user activities analysis in the built environment context. We have elected to use a KTH Live-in-Lab as a testbed in relation to the chosen living lab network of actors and stakeholders. We see an opportunity to increase the interaction between the building system and the human activity system through the service system integration. In other words, this thesis aims to investigate how new services in the built environment should be designed to support end-user's daily activities and well-being, and at the same time, help operate the building more sustainably (decrease electricity, water usage, and waste production).

 

By following a T-shape research approach, we started with a broader perspective on service design in the context of the built environment. A Delphi method was used for consensus building, and a co-creation approach between multiple stakeholders was adopted for the broad exploration part. The insights of the general study have become a foundation for several case studies that used mixed methods (Sustainable food service and Sleeping quality assessment). The result of the study consists of theoretical and practical implications. From the theoretical perspective, the thesis contributes to service design process improvement using a living lab environment and method and developed a framework for Bi-directional value exchange between the Building System (BS) and the Human Activity System (HAS). During the case studies a service concepts portfolio for KTH Live-in-Lab was co-created with multiple stakeholders, and two concepts were tested with active end-user engagement. The findings have been presented in four journal and two conference papers appended.

Abstract [sv]

Huvudsyftet med denna avhandling är att kommunicera motiv, process och resultat från detta forskningsprojekt som fokuserat på att utforska ämnet Slutanvändaraktiviteter i byggd miljö med tjänstedesign som metodikbas. För att kunna genomföra studien med en socioteknisk inriktning valde vi att använda KTH Live-in-Lab som testmiljö med dess ingående nätverk av flera olika typer av aktörer. Vi såg en möjlighet att öka interaktionen mellan byggnadssystemen i sig och mänskliga aktivitetssystem genom att tillämpa tjänstesystemsintegration. Med andra ord syftar denna avhandling på att undersöka hur nya tjänster i byggd miljö kan utformas för att kunna assistera slutanvändares dagliga aktiviteter och välmående. Samtidigt syftar avhandlingen till att supportera en mer hållbar byggnadsdrift så som att minska användandet av el och vatten samt minskning av avfallsproduktion.

 

För att kunna ta ett bredare grepp om tjänsteutveckling inom byggd miljö inledde vi studierna genom att tillämpa T-Shape-metoden som forskningsansats. För den bredare utforskningsdelen använde vi Delphi-metoden där vi arbetade med samdesign och skapa konsensus mellan flera olika aktörer. Insikterna från den bredare studien skapade en bas för utformning av fördjupade studier vid vilka en blandning av både kvalitativa och kvantitativa metoder användes (utvärderingar kring hållbar mat och sömnkvalitetfallstudier). Resultatet av bredd- och djupstudierna består av både teoretiska och praktiska implikationer. Från ett teoretiskt perspektiv bidrog vi till att förbättra tjänsteutformningsprocessen för byggda miljöer. Detta gjordes genom att använda KTH Live-in-Lab- koncept och - miljö som bas för utformning av ett ramverk där syftet är att skapa ett ömsesidigt värdeutbyte mellan byggnadssystem och mänskliga aktivitetssystem. I praktiken utformade vi, tillsammans med flera olika aktörer, en tjänstekonceptsportfölj för KTH Live-in-Lab och testade två olika koncept med hjälp av aktivt deltagande från de boende i denna miljö. Alla insikter och slutsatser från de utvalda ämnena i denna avhandling har presenterats i fyra vetenskapliga artiklar och två konferensartiklar.

 

Nyckelord: tjänstedesign, mänskligt aktivitetssystem, byggnadssystem, servicesystem, aktörsnätverksanalys, living lab, hållbart byggande.
