Our presence in buildings is often so self-evident that we no longer seem to be aware of the space in which we work and live. But how does that actually work? What is the influence of buildings on people? And how do we involve end users? Mark Mobach takes us on a quest of the Facility Management professorship for properties of the built environment that determine a positive influence on people. His approach is multidisciplinary, with a lot of attention for health and well-being.
