26 UP-GRADABLE BUILDING HOW TO MAKE USE OF EPBD AND nzebs? We need to clarify what we want to achieve by construction nzebs. Are the on-site systems primarily for the use of the buildings? Define the nearly Zero-energy so that the energy generated can be fully used in the buildings, even the peak season in energy generation Define the nearly Zero-energy so that the vital functions of the buildings are secured in the case of a grid failure OR: Are we trying to improve the energy mix in the grid? Define the target capacity for the on-site systems to replace certain existing high-emission capacity in the grid Define the nearly Zero-energy so that the target capacity gets constructed Secure the compensative capacity in the grid Arrange a viable financial compensation for the owners of the on-site systems and secure the maintenance of the systems Change the EN standard on carbon footprint calculation so that a building gets full benefit for feeding the grid 26
