    What this call funds

    This call funds projects that demonstrate practical ways to capture and reuse waste heat from small IT rooms or edge data centres (100-500kW) inside buildings, and to manage that heat more intelligently. The goal is to prove real, working systems in both cold and warm climates that recover excess heat for uses like building heating, water heating, or district heating networks, plus build convincing business cases for these solutions.
