The center combines the research activities of its core members and also engages in research projects for, among other clients, municipalities and healthcare institutions. Integration is a key term. Characteristic for the work of the Expertise Center is the ambition to integrate relevant medical knowhow in the analysis and design of the city. The design disciplines have developed the most adequate vocabulary for the analysis of the built environment and the way it impacts lifestyles. The urban discipline can map the distribution of people’s activities (‘functions’) in space (‘zoning’); it analyzes the connections between these zones (roads, highways, public transportation, but also telecommunication, mobile phones and the Internet), which ideally results in precise assessment of the citizens’ daily living patterns. The health performance of cities is determined by many aspects, among others the building types and the design of public space (street profiles, greenery, water). The Expertise Center uses a simple but adequate model of the healthy city as a bridge between urbanism and its intended impact om public health (the assessment of which is a task of health professionals).
