This chapter presents the formula framework for modeling the energy-ecological urban transformation. The energy model is discussed in detail. First, guidelines and assumptions are presented, the division of the model space into urban and landscape spaces is explained, and then the current and future energy demand is modeled on an area basis. Building on this, the potentials of urban and landscape spaces for renewable energy generation are recorded and compared with the previously determined energy demand. This comparison allows the determination of the energy autonomy of a model space, as well as the development of plus-minus regions. The results can be visualized in diagrams and plans for previously chosen scenarios. In a second derivation, the climate-relevant emissions of the urban and landscape spaces and their carbon sequestration potential are modeled. Finally, further possibilities for modeling energy-ecological parameters such as the green share, biodiversity, or the water balance are pointed out.
