Smart Homes and User Values: Long-term evaluation of IT-services in Residential and Single Family Dwellings
KTH, School of Architecture and the Built Environment (ABE), Architecture.
2009 (English)Doctoral thesis, comprehensive summary (Other academic)
Abstract [en]

Do residents find value in smart home functions? How should these functions be designed to offer user benefit? These were the governing questions of this study that involved nearly 200 families in three different housing projects during five years of occupancy. The housing units were equipped with advanced smart homes solutions, electronic and digital devices to control them, and a set of functions to increase comfort, safety and security in the homes.

The evaluations of the residents' use and benefits were accomplished in two different phases, i) evaluation of the user expectations' before and direct after occupancy and ii) long-term experiences after 3-5 years. A third phase of the study represents a radical shift in view. Issues related to innovation and organisation of service delivery were brought into the fore.

The research is founded on the multiple case-based methodology. Literature studies were effected. Data acquisition was based on interviews and questionnaires. Theoretical models from different research areas were used in order to analyse observations and to arrive to grounded conclusions.

Important conclusions include the fact that smart home functionalities must be developed as close as possible out of the users' genuine needs as experienced in their daily lives. Failure to attain accessibility to a certain function will cause disappointment and will be forsaken. To gain and over time preserve the user's trust in smart home functions or in a system as a whole is conclusive for the their use. Another conclusion is that a viable business model for smart homes must include the occupancy phase. Surveillance and maintenance of smart home systems must be secured over time. It is argued that the failure of establishing a viable long-term service to homes to the benefit to the user depends highly on the market’s ability to supply the homes with appropriate services over time. Possible ways to mediate revealed shortcomings are outlined and what role and responsibility the housing construction industry has to consider with the further development of smart homes.

Abstract [en]

Stockholm during the years 1999-2002 some residential housing units provided with advanced IT-based functions were developed, also called smart homes systems. ne purpose was to offer the residents an augmented living environment mainly regarding security and comfort. Only the IT company that originally developed the basic system fully knows it in depth, a fact which has shown to become very unfavourable for the residents. The running cost, also for minor changes of the functionality of the system, has turned out to be high and prohibiting. Also the contracted regular maintenance requires access to unique competence, which also has become costly. Recently the company has indicated a replacement of the smart homes system with a simpler one based on the Internet. Business models for viable home systems should include the occupancy phase, which to date have been neglected. A crucial issue is who will and can assume long-term responsibility for surveillance, maintenance, and added functionalities over time. This paper will discuss some principal questions and prerequisites regarding business viability in relationship to smart home systems, and its significance for business modelling.

Abstract [en]

This article explores the residents' attitudes to and acceptance of Smart Homes. The results are based on surveys of two residential units fit with advanced smart home systems. The systems offered functionalities of different kinds as alarms, energy measurement, booking of common facilities, broadband connections and electronic keys. The buildings were first occupied in mid 2001 and early 2002, respectively. The original smart home systems were in operation until end of 2005, when they ultimately were replaced by simpler ones, based on the web, a change not foreseen from the beginning. The extended period of time offered the possibility to study the residents' long term attitudes, expectations and demands on smart homes with their installed and perceived functionality. The questionnaire surveys focused on the residents experiences and included questions of their actual use of the smart home systems and opinions regarding accessibility and easy of use. Albeit functionality related to current demand is a basic requirement, two other concepts, viz, accessibility and trust, have appeared to be fundamental for a positive attitude and acceptance of various functions that constitute a smart home. Related issues are developed and further discussed in the article.
