The project goal is to demonstrate and monitor a “net zero 2050” strategy in the residential sector using the kPEB ALTE SCHMITTE Güttingen housing development. The net zero GHG reduction path is to be measured, visualized, discussed, and optimized.

The project focuses on the effects of “optimization measures” in operation. The accumulated GHG emissions from construction and maintenance are determined as a starting point. These are compared with verified benchmark and measured real data in operation and extrapolated to 2050 using simulated scenarios. The effects of selected measures to avoid, substitute, and offset CO2 emissions (taking into account the valorization of surplus renewable energy) are shown using stakeholder-specific dashboards and discussed and evaluated with stakeholders in terms of scalability.

The dashboard is developed in an iterative process and provides residents and stakeholders with a comprehensive but understandable overview of the CO2 GHG reduction path through the operation. For implementation, the phases of design thinking are integrated with a co-creation approach, and agile methods are used for the development of simulation software and dashboards, as well as scaling concepts.
