Research On BIPV Design Of Residential Building In Hot-summer And Cold-winter Area

Since the new century, to take advantage of green energy has become the key point to sustainable development. Solar photovoltaic building came into being from this context, and has made rapid development in our country. Though great progress has been taken in the field of energy conservation, but most of them still stay in exemplary project; on the other hand, residence which is occupied for a huge part of quantities in buildings, are calling for relative works. Besides, taking the special weather environment of the hot-summer and cold-winter area into account, frequent energy use and waste are easily happened. On the basis of these problems, the paper sets the development status of the BIPV for residential buildings in hot-summer and cold-winter area as the research foundation, taking the following discussion:First of all, the essay introduces the basic components of the PV system, the type and corresponding characteristics of them, also common combination of photovoltaic systems in residential buildings are showed. A preliminary analysis of the climate characteristics in hot-summer and cold-winter region are taken, such as solar radiation, temperature, climate and other micro- anemometer factors which can easily affect the BIPV design works; focus on dwelling type of residential buildings to classify separately from its category, shape, form parts to group them in recognizable categories.Secondly, principles aimed residential buildings for photovoltaic design are established, mainly taking energy conservation, local adaptation and affordable in environment these three principles into consideration; mainly explores a kind of design thought with an integrated, efficient and synergetic factors from the perspective of photovoltaic technology.Finally, according to the forms that BIPV system combined with building structures from the architectural design, three parts are divided: PV-roofing system integrated design; PV-elevation system integrated design; PV-structure system integrated design; exploring possible ways to deal with the various parts of the building in different BIPV integration situation. Meanwhile, a typical dwelling in Nanhu district, Wuhan are chosen, records its BIPV system using situation in March 2015- March 2016 electric energy and expand the data analysis result, get a more effective photovoltaic design plan, so as to achieve a more mature BIPV designIn this paper, though hot-summer and cold-winter area is chosen to be the scope, but the BIPV planning strategy and BIPV design method for single building can also be applied to a more extensive category, but changes with specific environmental factors in different regions are needed. Finally, hope that the results of this study can be a useful reference for the design of residential buildings in BIPV integration.
