“…The prototype was placed in the mirror box artificial sky chamber to collect data under the standard CIE overcast sky for 30 minutes. The mirror box artificial sky chamber has been previously validated [12]. In comparison, the measurement was carried out on the CADL building's rooftop (eight stories), located at the Institut Teknologi Bandung, to collect data under the actual condition.…”

Building energy use contributes up to 40% of total global energy use and increases by 8-10% every five years, encouraging the development of technology-based renewable energy sources. Building-Integrated Photovoltaic (BIPV) is a potentially relevant application of integrated PV in buildings which, it provides electricity cost savings, and increases the architectural attractiveness of a building. In contrast to conventional PV installations on building roofs, vertical PV installations are significantly influenced by the building orientation and the transparency of the PV. Study and analysis were conducted to implement BIPV windows in tropical climates using experimental measurement methods in energy output and indoor daylighting in four cardinal directions. This research was done by modelling a simple 2 × 2 × 1 m3 room with a PV solar window glazing made of Monocrystalline silicon 105Wp, placed on the roof of CADL Building, Institut Teknologi Bandung, Indonesia, for four days. The measurement results indicate that South is the most recommended orientation for installing BIPV windows for tropical areas in Bandung with the performance indicators for energy output = 564 Wh, DA300 = 100%, UDI250-750 = 93%, UDI100-3000 = 100%, and UDI>3000 = 0%. In contrast, West and East orientations are not recommended because of the significant difference in energy output and illuminance in the morning and the afternoon.

The contradiction between the indoor environment and building energy consumption has been controversial. The design of building envelope involves many parameters such as window size and exterior wall material. These parameters have significant influence on building energy-saving design and indoor environment. In this paper, nondominant sorting genetic algorithm-II (NSGA-II) is utilized to calculate winter heat consumption, indoor total lighting energy consumption, and thermal comfort. The Pareto method is used to select the compromise solution and effective value of each building parameter. Different from other studies, we add more architectural design variables into the model calculation, which can bring architects more detailed energy-saving design content.
