Buildings produce nearly 40% of annual global CO2 emissions. Of the total emissions, building operations are involved in 28% per year. Therefore, it is necessary to reduce energy consumption in buildings, including by utilizing renewable energy. Indonesia as a tropical country has abundant solar energy sources, this potential can be utilized through Photovoltaic Solar Power Plants. Photovoltaic Insulated Glass is a type of glass integrated with photovoltaic, which has the ability to convert sunlight into environmentally friendly electrical energy. This type of glass is also equipped with heat insulation technology to reduce heat radiation through the building envelope. This research was conducted to examine the identification of PV Insulated Glass potential in energy substitution, namely its ability to generate new renewable energy and thermal insulation resulting from the use of this material. The research is quantitative with semi-experimental methods, namely energy use intensity simulation and photovoltaic performance simulation of several variants of Photovoltaic Insulated Glass compared with other architectural glass materials on three different mass form objects. Optimization of the PV Insulated Glass material was considered based on simulation results that showed low energy consumption, but high net energy generation. Research on 13 iterations of glass configurations, with 3 types of photovoltaic layers, and 3 different building mass forms, showed that the PV Insulated Glass type with Low-e Glass (Low Emissivity Glass) layer with low U-Value has sufficient insulation to reduce cooling loads, and photovoltaic layers with high efficiency has the potential to provide clean energy substitution in building operations. The best orientation for the placement of photovoltaic panels is on the East and West facades. Based on simulation results, PV Insulated Glass has the potential to substitute energy for high-rise office buildings with a maximum potential of 11.71% of EUI and a minimum potential of 6.05% of EUI.
