Passive buildings are proving to be a solution to menaces of energy crisis and greenhouse gas emissions across the world. Such buildings tend to exhibit low energy demand owing to their cleverly designed envelopes, which comprise of walls, roofs, doors, windows and other openings. This requires use of new materials and technology, leading to an increased initial construction cost. However, with reduced energy consumption, the lifecycle cost of a passive building may be lower than that of a conventional building. These passive buildings also need to cater to occupants’ comfort which is subject to local climatic conditions and climate change. This article discusses economic feasibility and climatic adaptability of a passive building, in addition to advances in passive building strategies. Owing to lack of general awareness and standards related to passive building construction, these buildings have not achieved enough popularity. While many countries are striving hard to bring passive buildings to common masses, a large number of countries are yet to initiate the move. This article outlines several active organizations, standards and rating systems for passive buildings. This article also presents some of the recent research trends and a comprehensive bibliography for the benefit of researchers and practitioners.

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

Several new devices related to the field of small green energy, which have a social significance for countries such as the Republic of Kazakhstan, are proposed, particularly, a combined vehicle based on a dirigible with increased travel capability, as well as non-trivial focusing systems that significantly simplify pointing at the Sun. It is shown that at the first stages of the introduction of such devices, it is advisable to use them for the gamification of the educational process. This is justified, first, by the fact that the introduction of small green energy systems into widespread use is not only a technical, but also a social problem, respectively, any nontrivial innovations in this area are initially advisable to introduce in the form of children's games.
