The increasing integration of renewable energies requires new approaches to systematically tap into and coordinate the flexibility potential of buildings. The project supports international cooperation within the framework of IEA Annex 96 by recording, analyzing, and structuring Swiss flexibility-oriented activities in the areas of forecasting methods, test environments, flexibility products, and CO2 assessment. The aim is to provide an overview of current and upcoming Swiss activities, highlight synergies, and identify gaps in research. Through this role as a knowledge broker, the HSLU strengthens Switzerland's visibility and strategic positioning, promotes international exchange, and facilitates the effective use of building flexibility for a secure, economical, and sustainable energy system. At the same time, this creates a knowledge hub for flexibility activities in Switzerland.
