sEnSys

The “sEnSys” project involves the development and implementation of a comprehensive concept for energy-efficient, cost-effective, and grid-friendly buildings that achieve energy and climate neutrality on an annual basis. The project’s goal is to demonstrate the retrofitting of existing multi-story apartment buildings in the cooperative housing sector. To this end, a residential building from 1968 with approximately 32 residential units was selected. 
The project’s focus includes technical and economic aspects as well as user acceptance of the renovation. To achieve cost-effective operation, operating models for electricity and heating concepts are being examined and implemented. The additional costs for components and control functions are to be offset by increased system efficiency and thus lower energy consumption costs, the elimination of external utility billing, and the full utilization of tenant electricity options. A study will examine the costs of different variants (e.g., minimal and ambitious).
