ABSTRACT
Glazing is considered the preferred solution for the constructability, esthetics, and comfort of commercial buildings, as glazing can protect occupants from external environmental factors, provide light transmission, and provide views and ventilation. At the same time, in the context of climate change and global warming, the use of renewable energy such as solar and wind energy is being promoted. In particular, solar energy has become a renewable energy source that is clean, infinite, and contributes to energy security and sustainable development at a reasonable cost. Therefore, the study proposes a method to support the decision-making process of installing solar panels on the vertical glass facades of the building in the case that the remaining radiant energy from the sun is only transferred to the interior of the building. The life cycle analysis and life cycle costing methods are applied to consider both environmental and economic aspects. The proposed method can (1) minimize the project cost (including initial investment cost and operating cost) during the building's lifetime; (2) analyze the optimal budget to minimize the total life cycle cost of the building over its lifetime and maximize the renewable energy generated from the sunlight entering the building from different directions. The results show that for different initial investments, the investor has a corresponding solution for choosing an optimal installation ratio for each type of glass in combination with the installation ratio of solar panels on the facades to achieve the optimal energy efficiency and environmental performance. This study is useful for investors in the selection of energy-saving solutions in office buildings in the initial phase of the project life cycle
