Improved transportation, green buildings and intelligent power supply systems steer rapid urbanization into sustainable development.
The challenges presented by sustainable development of cities are immense. China has reached the “urban tipping point”, with about 51 percent of its population or 675 million people now living in cities. By 2030, this number will likely be one billion. Cities are responsible for around two thirds of all energy used, 60 percent of all water consumed and 70 percent of all greenhouse gases produced worldwide. To face the multitude of challenges arising from urbanization and demographic change, sustainable cities are assessing ways to improve the efficiency of their infrastructures. With the right technology, cities can become more environmentally friendly, increase the quality of life of their residents and cut costs, all at the same time.
Siemens aims to contribute to the sustainable city development in China. Sustainable and eco-friendly solutions for green buildings, transportation infrastructure, public safety systems and healthcare can help to create new and sustainable cities in China. Siemens and Beijing are deepening their comprehensive cooperation in infrastructure construction and urban development, and actively promote Beijing’s sustainable development, to build Beijing into a global city with Chinese characteristics.
Siemens initiatives such as the worldwide Sustainable Cities Roadshow “Green Mobility, Green City” continue to promote ideas for the sustainable city of the future. Together with Shanghai’s Tongji University, Siemens works on sustainable designs for eco-city models.
A careful balance of energy supply, energy security, affordability and environmental impact helps to assure a sustainable energy supply for cities and metropolitan areas.
Shanghai’s ever-growing energy needs are satisfied by facilities like the Waigaoqiao coal-fired power station. In China, the average efficiency of coal-fired power plants is 36%. In conjunction with the independent innovations of Waigaoqiao No.3 Power Plant, the advanced technology from Siemens helps the power plant achieve the power supply net efficiency of more than 46%, which sets a "China Benchmark" for the power sector in the world.
To meet the growing demand for energy, China not only builds powerful plants for low carbon fossil power generation but also concentrates on the sustainable development of facilities that use CO2-free and renewable energy sources. The country is the world’s fastest-growing wind market, and its installed wind energy capacity has doubled each year since 2005. By 2020, China hopes to have wind energy plants with a total combined capacity of 150,000 MW in operation. With the opening of its rotor blade plant in Shanghai in November 2010, Siemens, as the world market leader in offshore wind farms, is contributing to this sustainable development.
Energy is often generated at locations far removed from the cities where it is consumed. High-voltage direct current transmission (HVDC) is an efficient and energy saving way to transport power to a sustainable city and its residents. A highlight project is the 1,400-kilometer “Electricity Highway” that delivers eco-friendly electricity from hydroelectric plants in Yunnan province to the megacities on China’s southeastern coast. At a record 5,000 megawatts and 800 kilovolts, the world’s longest high-voltage direct current transmission systems supplies up to five million households with electricity. Its low carbon use of hydropower eliminates 30 megatons of CO2 emissions that conventional local power plants would otherwise produce.
Smart grid solutions will be vital to ensure secure energy supplies for the sustainable city of the future. Components such as decentralized energy generation and electric vehicles need to be integrated into the smart grid. New concepts include power grids designed to accommodate fluctuating power feed-in when using renewable energy sources. Static grid operations of the past will have to be transformed into a “living″ infrastructure that enables flexible and fast communication between power producers and consumers. To foster the joint development of smart grid project opportunities in China, Siemens signed a Strategic Cooperation Framework Agreement with Wasion Group in 2010.
Traffic is one of the biggest contributors to climate destruction – and mobility continues to increase in our society. Cities need efficient, affordable and low carbon solutions for local public transportation to prevent traffic jams and reduce CO2 emissions. In June, 2012 Siemens launched the first road show for its railway signaling products and technology to support sustainable development in China, themed “Green Mobility, Green City”.
For sustainable development, smart cities rely on efficient mass transportation systems. From the very beginning, Siemens has supported the construction of the Shanghai metro which started operating in 1995. Since then, we’ve provided key components for the extension of the Shanghai metro system. Siemens also is committed to supporting the infrastructure development of Beijing and other Chinese cites. Siemens' advanced signaling system helps to guarantee the successful operation of Beijing metro Line 10 and Olympic Branch Line. And in June, 2012 we were awarded the contracts to supply advanced signaling systems for metro lines in Suzhou, Qingdao and Chongqing.
For intercity travel, rapid rail transit is an environmentally-friendly alternative to cars and airplanes. Guang-Fo Line, China’s first intercity mass transit line opened its first section in October 2010 – equipped with state-of-the-art technology by Siemens. The second section will follow in December 2012.
Just as public transportation continues to grow, so does car traffic. Intelligent traffic control systems contribute to helping traffic flow. They reduce fuel consumption, air pollution and noise by allowing cars to stop less frequently. In Wuhan, the capital of Hubei province, Siemens equipped more than 420 junctions with complete traffic control technology. The Wuhan Urban Traffic Control System has significantly contributed to improving road traffic efficiency in the central Chinese metropolis. At Shanghai Hongqiao Airport, Siemens has implemented China’s biggest parking management system to better serve the large flows of visitors during Expo 2010. The project is helping to turn Hongqiao Airport into a key traffic hub in Shanghai.
Siemens is convinced that electromobility will play a key role in sustainable development of future urban transportation. By integrating electric cars into the smart grid, they not only consume low carbon energy but become a part of the energy system. During peak power generation times electric vehicles store energy which is then returned to the smart grid at times of high demand. At the end of 2011, Siemens installed 140 charging stations for electric cars in Shanghai.
Air traffic plays a significant role in metropolitan regions. In addition to efficient passenger processing, airport operators value smooth and efficient baggage handling. At Terminal 3 of Beijing International Airport, Siemens provided one of the world’s largest and most modern baggage handling systems. Every hour, 19,200 baggage items can be checked in, sorted and transported to their destinations over a 68-km-long network.
In order to remain competitive, modern cities also need an economical, efficient and reliable postal service. In Nanjing, China Post has established the biggest express and logistics center in Asia. Siemens solutions like parcel sorters and sorting control systems supported Nanjing Hub to become the core of the sorting and distribution network of express mail service in China.
Buildings have enormous potential for improvement – up to 40 percent of their consumed energy can be saved using intelligent building technology, sustainable architecture and comprehensive energy solutions.
Assessing a building’s cost-effectiveness means taking into account all the costs that will be incurred during its life cycle – not just development costs. Savings potential can be maximized through transparent use and operation, ongoing upgrades and improvement of individual components – or through comprehensive energy modernization and accompanying energy services. This maximized energy efficiency takes pressure off public sector budgets while protecting the environment at the same time.
Green buildings require an efficient infrastructure, accurate information management and continual real-time maintenance. With Total Building Solutions (TBS) Siemens makes it possible to integrate all systems that are part of the building services infrastructure, such as heating, ventilation, climate control, access control and security systems. Totally Integrated Power (TIP) provides all the necessary support to reliably distribute power in buildings. Siemens solutions help make buildings simpler to run and function more reliably – at a lower cost.
Siemens technology was used to modernize the Yangpu District government building, optimizing heating and air-conditioning systems, lighting and building automation. To assure yearly energy savings, an Energy Saving Performance Contracting model was used. The local government saves 16 percent on energy costs for the low carbon building as well as 600 metric tons of CO2 emissions per year.
Another example is the Siemens building in Shanghai, which was officially opened in October 2011. Employing Siemens green building technologies, it was awarded the LEED gold certification, enabling high energy saving and low carbon emissions. It is recognized by the Shanghai government as one of the most energy efficient office buildings in the city, effectively reducing energy requirements by 30 percent compared with energy consumption standard in China and cutting down carbon emission by over 1,400 tons every year.
Building safety and security is not just about protecting assets. It also involves ensuring people’s safety. Siemens takes a holistic view of building safety and security, protecting buildings, assets and people. Its portfolio encompasses universal safety and security solutions and services, focusing on access control systems, intruder detection, video surveillance systems, field service control centers and emergency management systems. Thanks to the fire alarm and voice evacuation system from Siemens, the Jin Mao Tower – comprising the Grand Hyatt Shanghai, the world’s highest hotel – provides a safe and comfortable working and living environment for thousands of people.
Lighting accounts for almost 50 percent of a building’s energy consumption. The innovative OSRAM lighting systems are fully intercompatible, save energy and money and actively protect the environment. The new stars in lighting systems are LEDs. More than 10,000 OSRAM LED fixtures illuminate the facade of the Guangzhou International Finance Center (IFC). The highly efficient OSRAM LED lamps last many times longer than conventional incandescent lamps and consume 80 percent less energy.
Clean water is crucial as far as public health and quality of life are concerned. Water treatment, supply and management present a challenge to cities and metropolitan areas. A reliable and safe supply of clean water can only be achieved by purifying drinking water as well as wastewater treatment and reuse. Cities are confronted with rising energy costs, increasingly strict environmental standards and – in some regions – water scarcity.
Siemens offers the largest selection of water and wastewater treatment solutions in the industry sector. SIMATIC process controllers and SIWA PLAN water management solutions help plants to operate as cost-effectively as possible. They offer users fast access to a wide range of information and use data processing to point out potential problems before they become an issue.
In Suzhou, located in the province of Jiangsu in Eastern China, Siemens SIMATIC PC 7 Process Control System is at work in one of China’s largest water treatment plants. The plant is modern, with a high degree of automation, and Siemens Totally Integrated Automation was the perfect solution for the plant, which required a system that was reliable and easy to maintain. Operational errors are minimized with centralized process monitoring and control in the central control room, with an intuitive operator interface. Data and process transparency assist the plant owners in reducing operating costs.
Healthcare too has witnessed a paradigm shift regarding the use of energy and raw materials. Both ecological and economical requirements exacerbate the challenge of creating sustainable infrastructure solutions for cities as well as rural areas. Siemens helps hospitals to pave the way into a sustainable future – with Green+ Hospitals.
The modular Green+ Hospitals concept offers means to address both economical and ecological demands in healthcare. This helps hospitals reduce energy costs through energy optimization, building automation and the use of energy-saving equipment, while simultaneously ensuring more comfort for patients. In parts this can be achieved by low dose technology in computed tomography. Over the years, Siemens has been highly successful in integrating many innovations into its scanners that significantly reduce radiation dose in comparison to other systems available on the CT market. In addition Siemens has issued a “Guide to Low Dose” that gives a detailed explanation of the functions currently available to reduce the dose in radiological imaging from Siemens. A smooth and safe workflow with structured clinical pathways, short examination times and the comprehensive use of IT are also key to the economic efficiency of a hospital.
In February 2010, the China Hospital Association and Siemens agreed on a strategic paper on Green Hospital development. The aim is to implement a Green Standard for China’s hospitals. Furthermore, Siemens Healthcare and Huashan Hospital in Shanghai agreed to develop integrated approaches combining in vivo and in vitro diagnostic solutions.
Doctors also plan to combine the advantages of traditional Chinese medicine with those of Western science. To keep medical technology at the forefront of these changes, Siemens is working with Chinese partners to develop new treatment methods.
