This study aims to evaluate the optimal size of the hydrogen facility to be installed in a zero-energy district in terms ofload matching and facility efficiency. A mismatch between energy generation and consumption is a common occurrence in zero-energydistricts. This mismatch adversely effects the energy grid. However, using an energy carrier such as hydrogen can solve this problem. To determine the optimal size of hydrogen fuel cells to be used on-site, simulation of hydrogen installation is required at both district-and building- levels. Each case had four operating schedules. Therefore, we evaluated eight scenarios in terms of load matching, heatloss, and facility operational efficiency. The results indicate that district-level installation of hydrogen facilities enables more efficientenergy use. Additionally, based on the proposed model, we can calculate the optimal size of the hydrogen facility.
