Cctv newsToday (24th), the world’s first super-class zero-carbon building was officially opened in Qingdao, Shandong. It is called "super-step" because in addition to photovoltaic power generation, this building also realizes 100% green energy replacement through cascade energy storage batteries and new energy vehicles. The official opening of the building marks new progress in zero-carbon building in China.
The world’s first "super-order zero-carbon building"Officially opened in Qingdao
The world’s firstSuper zero carbonThe building is 117 meters high, with 23 floors of office area, and the average daily electricity consumption is about 6000 kWh.The zero-carbon mode of the building is different from the traditional photovoltaic installation on the roof. Building-integrated photovoltaic glass curtain walls are adopted on the east, west and south sides, which is equivalent to putting a "power generation coat" on the building to realize direct supply of direct current, which can not only be used nearby, but also effectively avoid the loss caused by the conversion of direct current to alternating current, provide about 25% green energy for the building, and reduce carbon emissions by nearly 500 tons a year.
At the bottom of the building, there is also a "hidden energy source", where 14 obsolete automobile power batteries continue to exert their residual heat. The battery is charged and discharged every day, which can not only store the surplus electricity generated by the photovoltaic glass curtain wall, but also store a large amount of clean energy that cannot be consumed in the power grid at a low price of 0.22 yuan per kilowatt hour during the deep valley period, so as to be used during peak hours or rainy days and cloudy days, and effectively adjust the electricity load.
CCTV reporter Yang Ziqing:In the cabinet next to me, the hidden underground energy is displayed, which is full of eliminated new energy vehicle power batteries. During the charging and discharging process, the batteries will be monitored in real time. Once the heat is out of control, the hook will automatically trip, and the batteries will fall into the pool directly below, which will be isolated from other power batteries, ensuring the safety and normal operation of the whole energy storage system.
Achieve 100% self-sufficiency in green electricity.
In the interview, the reporter learned that the digital system has brought effective support to the whole zero-carbon building. Through the comparison of multiple schemes, the five major stations, such as traditional substations and distribution stations, are integrated to achieve 100% self-sufficiency in green electricity.
Nearly 24,000 tiny sensors installed in the building effectively replace the traditional indoor switches, and realize automatic interaction between people and lighting, air conditioning and elevators in the building.By scanning the face, you can perceive the floor that employees need to go to in real time, and immediately arrange the nearest elevator to connect employees; When employees come to the office area, the lights and air conditioners will automatically turn on and turn off after they leave, effectively saving energy and reducing emissions.
Yu Dexiang, Chairman of TELD New Energy Co., Ltd.：With the consumption of green electricity, we can save about 2500 tons of carbon emissions every year. Through digitalization, the investment cost of this building has been greatly reduced, which is close to 20% to 30%, the operation efficiency has been improved by 30%, and the energy consumption cost has also been saved by about 30%.
Zhao Yue, Director of Energy Conservation and Green Energy Research Office of China Electronic Information Industry Development Research Institute.：Super Zero Carbon Building is not only a building, but also a complete energy ecosystem. The self-sufficiency of 100% green electricity has been realized, and a new model of zero-carbon building has been formed, which is conducive to solving the problem of power battery recycling, standardized centralized management and avoiding the environmental risks of battery decentralized disposal.
New energy vehicles can reverse power supply to buildings.
In this newly-built building, there is also the technology of reverse power supply for the building by cars. How is this realized?
Compared with the cumbersome traditional mechanical parking, the world’s first fully-automatic high-speed three-dimensional parking system independently developed by enterprises not only saved 50 million yuan in construction cost at the initial stage of construction, but also was more intelligent and efficient to use.
After the vehicle stops in the designated area, the robot will automatically dock and adjust the position of the vehicle. Then, through the high-precision and stable track system combined with gear drive control technology, the robot can move and start and stop the car quickly and accurately on the track, and the maximum parking efficiency of a single car can be controlled within 35 seconds. In this parking system, there is also a black technology that new energy vehicles supply reverse power to the building.
CCTV reporter Yang Ziqing at the reception desk.：The new energy vehicle behind me is supplying power to the whole building. The secret of reverse power supply is that this device is only the size of a bowl. With it, it is equivalent to installing an additional charging port at the bottom of the new energy vehicle. When the vehicle stops, the charging and discharging robot will automatically link.After the link is successful, the digital system will be distributed as needed to provide continuous and stable power supply to the building.
When the charging and discharging robot is connected, it can carry out a "millisecond-level" physical examination of the power battery on the car. When the voltage, current, temperature and other indicators do not meet the comprehensive indicators of the same battery in the large database, it will move the car to a safe position within 29 seconds, and step immersion will be carried out according to the thermal runaway degree of the battery to avoid danger.
At present,Only 300 cars are needed every day to provide 10 degrees for the building.electricity, it can solve nearly half of the energy consumption for the building, and each employee can also enjoy the benefits of 1.2 yuan per kilowatt-hour difference.In extreme cases, the reverse power supply mode of the car can also be completely adopted to ensure the normal and stable operation of the building.
Zhao Yue, Director of Energy Conservation and Green Energy Research Office of China Electronic Information Industry Development Research Institute:Through the intelligent energy management system, the building becomes a flexible regulating node of the power grid, which can cooperate with the power grid to cut peaks and fill valleys, relieve the pressure of peak power consumption, and improve the reliability of power supply. Its off-grid operation ability can ensure uninterrupted power supply for key loads.
Zero-carbon scene into life Accelerate the formation of clean energy network
In recent years, zero-carbon buildings and zero-carbon parks have blossomed everywhere, and in fact, various zero-carbon application scenarios have been integrated into our lives. What changes has "zero carbon" brought?
Recently, Da Sanmen Island in Guangdong has once again achieved the upgrade of "zero carbon island". The abandoned shrimp farm not only realized the complementary fishing and light, but also equipped with a "super charging treasure" of 10,000 kWh. Excess electricity can be stored during the day, and a 200 kW large fan newly installed at the top of the mountain can also deliver a steady stream of green power to the villagers at night.
Villagers told reporters that in the past, the cost of generating electricity by diesel on the island was close to that of 3 yuan. Now, not only has the cost of electricity been reduced to 0.62 yuan/kWh, but the inexhaustible electricity can also be sold to China Southern Power Grid to obtain additional income. Freedom of electricity use has been realized, and the number of tourists on the island has also increased.
Tourist jie feng:I have been to this island before, and the water and electricity supply is very poor, and there is often no electricity in the middle of the night. Now the electricity is available 24 hours a day, there is air conditioning, and the environment is beautiful. I will come here often in the future.
In Jinan, Shandong Province, the heating chimney in the urban area has also quietly disappeared, and it has been replaced by the longest "warm artery" in China. The total length of the long-distance heating project is about 130 kilometers, and the waste heat from two power plants in Liaocheng is sent to Jinan.It can not only meet the heating demand of about 100 million square meters, but also reduce carbon dioxide emissions by 3.6 million tons in the annual heating season.
The intelligent computing center cluster located in Gui ‘an, Guizhou Province is providing zero-carbon computing power for all parts of the country. Immersed liquid cooling combined with natural cooling technology of fluorine pump air conditioner can not only have faster and more accurate calculation power, but also effectively save electricity and reduce carbon emissions.The photovoltaic matrix equipped on the roof and distributed wind energy form a microgrid, which also makesGreen electricityThe coverage rate is 100%.
Lu Caipiao, Project Manager of Southern Network Digital Group in Gui ‘an Data Center:Save about 3,200 tons of standard coal every year, which is equivalent to planting 800,000 trees, significantly improving the energy efficiency of the data center.
The data shows that the proportion of coal consumption in China has dropped from 56.8% in 2020 to 53.2% in 2024, and clean energy generation accounts for 39.7%, and an efficient and clean energy network is accelerating.
Zhao Yue, Director of Energy Conservation and Green Energy Research Office of China Electronic Information Industry Development Research Institute:Efficient and clean energy network, first of all, is conducive to protecting green mountains and improving the living environment of human beings. For enterprises, it will significantly increase the proportion of green energy consumption of enterprises and enhance the green competitiveness of products. The construction of efficient and clean energy network will create a greener, smarter and more inclusive future.
