The aim of the Smart Business Disctrict project developed by Berliner Wasserbetriebe and Berliner Stadtreinigung in the InfraLab Berlin innovation network is to build a climate-friendly infrastructure using synergies that result from the proximity of company locations. Approaches for cooperation can include the sectors of energy supply, mobility including the necessary infrastructure, biodiversity, rainwater management, microclimate, the circular economy, and the shared use of social spaces and facilities. Based on a pilot project, a transferable model will be created for reducing emissions and resource consumption as well as reducing running costs and the specific space requirements of the companies involved.
