The creation of economically, socially and ecologically sustainable housing and work areas represents a major challenge for the regions, cities and municipalities of Switzerland. In view of the tensions arising from location competition and environmental, energy and climate policies as well as tight public finances and heterogeneous stakeholder interests, econcept is committed to a transformation towards sustainable regional development and sustainable building and infrastructure parks. To this end, we are researching new approaches and sustainable strategies in the field of construction and helping public and private institutions to develop, implement and evaluate programmes, measures and instruments. An important foundation to this work is the thorough analysis of the motives and behaviour of the stakeholders.
