Energy supply and storage optimization for mixed-type buildings

Energy efficiency and renewable energy solutions in buildings is an important actual research topic. Operating fixed costs of sustainable can be reduced by using optimization models. We developed a novel model applied it for mixed-type building with commercial, office, residential parts Finland. The determines the optimal configuration, dimensioning, operation different local production storage technologies power, heat, cooling. formulated as large dynamic linear or mixed-integer programming (LP/MILP) full year. result shows that district heating, cooling, storage, heat pumps, photovoltaics hybrid solution both reduce combined operating annually 27100€, support meeting nearly Zero Building requirements E-value limit 107 kWh/m2/a. Photovoltaics profitable when consumed maximally at building. While cooling storages are cost-efficient balancing demand supply, power still too expensive. District heating pump worked synergetically together, but were mutually exclusive choices equal cost.
