The aim of the project is to develop an energy and sustainability strategy within the framework of updating the urban planning for “Neckarbogen, Heilbronn.” In particular, the focus will be on the topics of "decentralized water management," "energy-efficient building quality," and "CO2-neutral energy supply." Energy standards for buildings will be defined based on individual potential, which arises from the spatial location and type of structural uses. The proposed energy system includes decentralized gas-powered combined heat and power (CHP) plants, combined with photovoltaic systems on rooftops. Active systems are to be aesthetically integrated into the roof landscapes, which are equipped with terraces and gardens. In terms of open spaces, water plays a significant conceptual role in the Neckarbogen project through the creation of two lakes and the immediate proximity to the old Neckar river. These will be fed by treated wastewater from a greywater treatment system for lightly polluted wastewater (e.g., from washing machines, showers, kitchens, etc.), leading to a 30% reduction in drinking water consumption.
