Abstract: Central energy supply units for district heating grids need to be planned for a relatively long usage due to large investments. During this long usage period, building retrofits may change the demand patterns of the building stock. These changes might have an effect on the used energy supply units. As static tools do not adequately address this, we propose to use dynamic building simulation for individual buildings to determine the future heat demand. In order to find good solutions for a retrofit order of the buildings and design of energy supply systems that meet the given technical requirements two individual optimizations are performed, both using evolutionary algorithms (EA). The methodology is applied to a research campus with over 200 buildings.
