Building-Integrated Photovoltaics is a key technology for the generation of renewable energy in the built environment, especially in case of high-rise buildings. A promising solution to reduce costs associated with the on-site electrical installation, is the factory pre-installment of a module-level converter and the electrical interconnection between the modules. An alternative for regular cabling in BIPV systems, is the use of laminated bus bars. The large capacitance of the bus bar reduces the required output capacitance of the module-level converter which is in term beneficial from a cost, reliability and power density perspective. In this paper, an experimental prototype of a BIPV laminated bus bar is designed and tested to highlight the electrical advantages compared to regular cabling. From the measurements, it turns out that the interconnection between the modules is an important design aspect to use the full potential of a bus bar system.

Needless to say, green buildings have now become an inevitable trend for the sustainable development of society, and they have paved a way for the harmonious coexistence between man and nature. The design of building facade is an important part in green building construction, to achieve the optimal energy-saving effect of building facade, scholars in the field have attached great importance to this aspect and they have done works to optimize it from constituent materials, structural forms, and thermal insulation properties, etc. For the same purpose, this paper proposed a new method for the energy efficiency design of building facade and a thermodynamic evaluation method. First, the paper analyzed the factors that can affect the energy efficiency design of the wall, windows and roof of building facade; then it gave the calculation methods of parameters that are related to the energy-saving performance of building facade such as the coefficient of building shape (CBS), resistance of heat transfer, and thermal inertia (TI); after that, the paper summarized tips for the energy efficiency design of building facade, put forward a thermodynamic evaluation method for assessing the energy-saving efficiency and economic efficiency of green building facade based on the life cycle theory, and it elaborated the calculation process of energy consumption, exergy consumption and total cost of each stage in the life cycle of the building facade; at last, the paper verified the effectiveness of the new design method and the proposed evaluation method with experimental results, and the research findings of this paper can be applied to the design and evaluation of other buildings.

In the modern city, the concepts of "intelligent building," "green building," and "net-zero energy building" have attracted the attention of worldwide scholars. [1][2][3] As one of the most popular green energy systems, the photovoltaic (PV) power generation system plays an increasingly important role in engineering applications for achieving promising performances on energy saving and emission reduction. [4][5][6][7] For the so-called buildingintegrated photovoltaic system (BIPV), especially in high buildings with large surface area, thousands of PV panels are installed on the building facades for collecting solar energy. [8][9][10] As buildings account for almost 32% of the world's total electricity power consumption, the promotion and popularization of green building techniques (e.g., the BIPV system) are of great importance for the worldwide energy saving and emission reduction. [11] The maximum power point tracking (MPPT) technique is an important and necessary part in PV systems, as it can ensure the system keeps outputting the maximum power under varying environmental conditions. [12][13][14] As shown in Figure 1, the BIPV system always suffers from not only the complex shadings caused by its surroundings, but also the dynamic incidence sunlight angles caused by the unpredictable occupants' behaviors. For example, in the modern BIPV system, the facades of building are completely covered by a special PV module, namely, the BIPV window, which can capture the solar energy by integrating special PV materials and can also work as the traditional windows. As illustrated in Figure 1, each of the BIPV window can be closed or keep a random opening angle. This may lead to a dynamic incidence sunlight angle of each BIPV window and may also lead to random shading for its lower floor.As a result, the fast and accurate MPPT control of a large-scale BIPV system is always difficult. To overcome this problem, some efficient MPPT approaches are widely developed in recently years. For example, Liu et al. developed a hybrid MPPT approach by combining the variable step-size MPPT algorithm with continuous conduction mode and discontinuous current mode. Their proposed approach was applied in a BIPV system and verified by simulation experiments. [15] To overcome the partial shading problem of the facade BIPV system, Ravyts et al. developed a distributed MPPT by means of embedded converters and a common direct current bus. [16] According to the result of their case studies, the proposed approach can obtain promising performance with overall high efficiencies. For the design and
