The purpose of this study is analyze the energy share ratio of the liquid type Photovoltaic Thermal System (L-PVTs), which produces heat sources directly available for heating and heating of buildings, this study calculated the energy demand of the target buildings and the energy production of L-PVTs using TRNSYS18 and calculated the energy share ratio of L-PVTs to the building share. First, the elements, materials and energy production principles of solar, solar and L-PVTs were investigated and analyzed using local and internal literature and prior research. Second, the optimal L-PVTs were proposed with copper suction cups, glasswool thermal insulation, and low-iron reinforced glass by conducting an energy analysis according to each component of L-PVTs. Third, a public building was selected as the target building, and the annual energy level per unit area of the target building was calculated as 70kWh/㎡. Fourth, the primary energy production per unit area of the target building was calculated at 97kWh/㎡, and the energy independence rate was 139%, which was calculated as ZEB 1 grade.
