Abstract
In order for the construction industry to be climate neutral and circular by 2030, a transition is needed that changes norms & values and the way of working. Within the construction industry 80% of the clients are public organisations, which can steer a sustainable transition by posing a demand for sustainable alternatives. In order to stimulate this, the Buyer Groups have been initiated. The Buyer Groups, consist of a small network of contracting authorities, who together formulate a shared market vision for a specific product. This, to create a strategical focus on sustainability, make clients responsible and to harmonize the demand.
The research question of this qualitative and explorative research is: 'How can Buyer Groups effectively influence relevant construction sub markets towards a climate neutral and circular construction industry in 2030, with a harmonized market vision?' In order to answer this question, innovation dynamics within different sub market, the requirements for an ambitious and feasible market vision, a contributing market consultation and a suitable design of the Buyer Groups, were being investigated by a literature study and case studies. The objective is to support future Buyer Groups in contributing towards a sustainable construction industry.
Within this research three different types of construction submarkets have been distinguished, which all have another relationship with their clients. This relationship determines another focus for the market vision and market consultations. Besides, the transition phase a market is in, also influences the appropriate focus of the market vision and market consultation.
The biggest remark to this research is that the real effectiveness of the Buyer Groups and their market visions have not been measured yet, because the market visions are about to be implemented.
