A red thread in my academic carrier of over 40 years is the development and sharing of knowledge about the experience and use of the built environment, including offices, health care facilities, childcare facilities, learning environments, housing, and public spaces. The latter is currently part of urban FM. My main drive to do this for such a long time is the willingness to contribute to an environment that enables people to conduct their activities in a satisfactory, comfortable, efficient and effective way, and that fits with the preferences, needs and values of organizations, customers, end users and society as a whole. In other words: to contribute to user-centered and value-based briefing, design, management, evaluation and further improvement of buildings, facilities and services.
