The living lab DELTA (“Darmstädter Energie-Labor für Technologien in der Anwendung ”, funding code: 03EWR002A-K) serves as a showcase for urban energy transition to demonstrate energy-optimized districts. The aim is to show that proven technologies for increasing energy efficiency and flexibility are economically feasible and socially acceptable. As a living lab, DELTA aims to act as a role model and achieve results that can be transferred to other cities. Several actors have joined forces in Darmstadt, which include large industrial companies, small and medium-sized enterprises, start-ups, municipal companies, and research institutions, coordinated by the Technical University of Darmstadt.
The project pursues a multi-layered, cross-sectoral approach. The focus is on the consistent increase of energy efficiency in all sectors, which is already considered to be the greatest usable potential of the energy transition, as well as identifying potential for shifting electrical loads over time. Both will be achieved through the intelligent linking of individual districts of the urban energy system and through sector coupling.
Subproject 1 realizes an energy-optimized residential district for about 3000 people on the site of two former US barracks, considering affordable housing. To achieve the German government's climate and energy policy goals in the building sector, it is necessary to increase energy efficiency and energy flexibility through the use of innovative building technology and operating strategies, in addition to the use of sustainable building materials and renewable energies. Combined with intelligent electrical and thermal networking, this is the cornerstone of tomorrow's energy-optimized districts. ISM+D and bauverein AG are jointly responsible for the subproject management.
