The dissemination of green architecture is one of the representative strategies of the architectural sector for the preemptive implementation of government-backed goals of increased greenhouse gas reductions. One implementation method is to realize zero-energy buildings through the convergence of passive houses and new and renewable energy. Energy self-sufficiency in residential buildings can be accomplished by the fusion of fuel cells with other renewable energy sources. To apply a fuel cell to a building, predictions of a building’s energy consumption and fuel-cell energy production should be conducted simultaneously. Although many existing studies and tools have been developed for predicting building energy consumption, research on the application of fuel cells to buildings remains insignificant. This study aims to derive an energy performance prediction equation for a 1-kW polymer electrolyte membrane fuel cell. To this end, operational data based on the partial load ratio were collected and analyzed, and the heat and power energy production and fuel consumption prediction equations of the corresponding fuel cell were derived.
