China's first solar energy building is about to be completed and put into use. As a cost park for photovoltaic power generation to enter the commercial and residential areas, new plastic packaging materials and new technologies, and a demonstration project for the integration of photovoltaic power generation and buildings, this solar photovoltaic building integrates the solar glass curtain wall into the overall design, and the external facade of the building adopts large-scale breathing solar glass curtain wall. The power generation of the whole building can reach 0. 3 megawatts, which is equivalent to a small power station. The electricity generated is directly connected to electricity

according to the personnel of Baoding Yuansheng RONGTONG Trade Co., Ltd. under Yingli group, the project contractor, the powervalley Jinjiang International Hotel, covering an area of 62 mu, is only the first phase of the "powervalley Plaza - 1.5 MW solar power generation system and sewage source heat pump renewable energy demonstration project"

1 after the completion of the whole diangu square. The 5 MW photovoltaic parallel power generation system can generate 1.71 million kwh of electricity annually, which can replace 1400 tons of standard coal and reduce 1100 tons of carbon dioxide emissions. At the same time, the air conditioning system in the building adopts sewage source heat pump air conditioning for heating, cooling and domestic hot water supply, becoming a domestic demonstration base for the integration of solar power generation buildings. At present, only Germany and Japan have small-area solar photovoltaic buildings in the world

the whole facade reflects the design concept of the circuit board. The stainless steel plate represents the electrical components on the circuit board. The solar glass module drives the pointer on the instrument panel to rotate through mechanical transmission devices such as springs and weights. The marked tension value represents the conductor. When the conductor connects the components, the concept of the circuit board is reflected incisively and vividly, becoming a beautiful scenic spot in China's power valley. Because different structural methods are adopted to realize the perfect integration of solar all glass modules and buildings, it will become a successful landmark building in the world that combines different solar module application methods with buildings

in terms of external enclosure structure, 5cm extruded polystyrene board is used for insulation on the roof of the building, 5cm thick extruded polystyrene board plastering system is used for the external wall, and low-energy hollow glass aluminum alloy windows are used for the external windows. In terms of the application of solar energy parallel power generation technology, the breathing solar glass curtain wall is adopted on the 5th to 24th floors of the south facade of the main building of the building, and the photovoltaic power generation technology is adopted on a large scale and from multiple angles, with an installed capacity of 0. 3 MW. Solar power generation will be incorporated into local electricity, which is a model project of domestic photovoltaic power generation. The attempt and innovation of the integration of photoelectric curtain wall and building is the first at home and abroad. It not only solves the problems of manufacturing, installation and technology, but also breaks through a number of scientific research achievements and obtains a national patent for judging the sealing performance of samples

in addition, the building also adopts a sewage source heat pump system. Its basic principle is to use the reclaimed water from the sewage treatment plant for plate heat exchange, which is used for heating, cooling and domestic hot water of the central air conditioning of the whole hotel; In order to highlight the design concept of energy conservation and environmental protection, reclaimed water is used for toilet flushing, fire fighting, car washing, watering, etc. in the whole building. Not only does the building achieve zero discharge, but also the reclaimed water after use will be returned to the sewage plant for secondary use as circulating water in the thermal power plant, so that the sewage can be recycled, and the utilization efficiency and economic value of renewable energy can be improved
