The Dubbelbeek project aims to create a zero-energy building in Apeldoorn that accommodates employees and integrates charging facilities for 100 electric cars. The project's financial feasibility indicates a payback period of approximately 11.9 years, with a potential energy neutrality of 89% without wood pellet combined heat and power systems. Key considerations include the building's energy demands, renewable energy integration, and the need for smart design in electrical infrastructure.
