New traffic concepts, green buildings with sustainable architecture, and intelligent power supply and water treatment systems help ensure a sustainable development of green cities during these times of rapid urbanization.
Sustainable development of cities poses a multitude of challenges and opportunities, especially in the Middle East. Between three quarters and circa 90 percent of the region’s population already lives in cities. And the numbers are rising. Around the world, about 70 percent of greenhouse gases, two thirds of energy consumed, and 60 percent of water consumption can be attributed to cities. Especially in arid regions, an efficient water supply is crucial. To face the challenges arising from urbanization and demographic change, cities are looking at ways to develop their infrastructures sustainably. With the right technology, cities can increase the quality of life for their residents, while also becoming more environmentally friendly. In other words: they can become sustainable cities.
Siemens is committed to being part of the Middle East’s success story. With the world’s most comprehensive environmental portfolio, we offer sustainable solutions for transportation infrastructure, green buildings, water treatment facilities, and public safety systems. Solutions that will help ensure sustainable city development – for existing cities as well as green cities of the future.
Siemens initiatives such as the worldwide Sustainable Cities Roadshow promote ideas for the smart city of the future. Siemens is also a thought leader in global climate change conferences such as COP18, in Doha, Qatar, offering sustainable, eco-friendly solutions.
Cities continue to grow as more and more people move to urban areas. This shift towards urbanization places increasing strain on existing city infrastructure systems.
Sustainable cities and communities need to optimize their infrastructures to provide modern, efficient and people-oriented services. Siemens helps them with this task: Our Infrastructure & Cities Sector provides sustainable technologies for green cities and metropolitan centers and Siemens Financial Services offers attractive financing solutions, some involving private investors.
International sports events are increasingly the reason for infrastructure investments. For the 15th Asian Games held in Doha, Qatar in 2006, Siemens erected a state-of-the-art temporary airport terminal at the Doha International Airport in Qatar in a record time of eight months. Siemens also contributed their expertise to design, develop, supply and implement a comprehensive physical security system, making the games a safe and pleasant experience for both visitors and athletes.
In addition to combating terrorism and organized crime and preparing for natural disasters, city administrations also need to protect buildings and large-scale events.
Siemens’ portfolio contains comprehensive security solutions and services focused on intrusion detection, video surveillance, access control systems, fire alarms and danger management. Siemens equipped the Police General Headquarters in Dubai with software and security technology. Thanks to a high-tech emergency call system, police, the fire department and ambulance services are able to respond more quickly and collaborate more effectively.
With its modular Green+ Hospitals concept, Siemens is firmly gearing its healthcare portfolio towards environmental care and sustainability. We help hospitals reduce costs through energy optimization, building automation and the use of energy-saving equipment, ensuring more comfort for patients at the same time. 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 and sustainability of hospitals. From January 28 to 31, 2013, Siemens presented its solutions for a sustainable healthcare infrastructure at the “Arab Health 2013”.
Traffic is one of the biggest contributors to climate destruction – and mobility continues to increase in our society. Sustainable cities need efficient and affordable solutions for local public transportation to prevent traffic jams and reduce CO2 emissions.
A cross-system helps to guide the different traffic flows in an environmentally friendly and efficient manner. In 2007, Siemens equipped a command and control center for uninterrupted traffic surveillance and control in Abu Dhabi city with its 24/7 traffic monitoring systems. The SITRAFFIC Concert traffic management system helps operators make the right decisions and respond to traffic congestions.
Siemens offers products and solutions for safe, attractive and environmentally friendly local public transportation: Hybrid buses with ELFA drive systems harness a significant amount of the braking energy and use 30 percent less fuel. The fully automatic and driverless Avenio low-floor tram is another example for environmentally friendly transportation with significant savings potential.
In summer 2012, Siemens was awarded with an order from the Qatar Foundation to provide the Middle East’s most energy-efficient tram system. We will supply 19 three-unit Avenio trams with hybrid energy storage systems, which consume up to 30 percent less energy per year and produce less CO2 than vehicles without such systems. Qatars’s first tram system is to become operational by fall 2015 and will set a new benchmark for sustainable public transport infrastructure in the region.
At the beginning of 2011, the Siemens Mobility Division successfully completed the first phase of electrification of the “Al Mashaaer Al Mugaddassah Metro" project. This new rail link along the pilgrimage route in Mecca allows pilgrims to travel quickly and comfortably between holy sites in and around Mecca.
In Dubai, the integration of public transportation systems is a priority. In order to allow people to reach their destinations without delay, subway lines, buses, and marine transport in the megacity are linked by multimodal connection stations. At all subway stations a shuttle bus service is available, even in the suburbs.
Electromobility will be a key technology for private traffic in sustainable cities. By integrating electric vehicles into the smart grid, they not only consume energy but become a part of the energy system. During peak power generation times – for example periods of strong wind or intense sunshine – electric vehicles store energy which is returned to the grid in times of high demand.
Air traffic is growing rapidly and plays a significant role in metropolitan regions. In addition to efficient passenger processing, airport operators value smooth and efficient baggage handling. Siemens offers a highly diverse portfolio, including completely new baggage handling concepts.
At the Bahrain International Airport, for example, Siemens provided the turnkey installation of a new remote baggage handling facility. And at Terminal 3 of Dubai International Airport, Siemens installed a state-of-the-art baggage handling system to process the increasing number of transfer passengers, enabling the airport to expand its capacity to handle 18 million passengers per year.
Around the world, cities are responsible for two thirds of all energy consumption and 70 percent of greenhouse emissions. A sustainable energy supply is crucial: Energy security, affordability and environmental impact must be carefully balanced.
Sustainability in the energy conversion chain begins with power generation. In Abu Dhabi, the Shuweihat combined power and desalination plant, a Siemens turnkey project, can generate approximately 5,000 megawatts of electricity and 1.4 million cubic meters of drinking water daily. More than half of the energy released through gas combustion is converted into electricity. In 2012, the Barka III and Sohar II, two turnkey combined cycle power plants located in Oman, began operation in simple cycle mode and will be extended to combined cycle mode in 2013.
In the future, smart grids will be the only way to ensure secure energy supplies. Components such as decentralized energy generation and electric vehicles need to be integrated into the grid. New concepts include power grids designed to accommodate fluctuating power feed when using renewable sources. Siemens is actively involved in developing smart grids to create a sustainable future.
Renewable energy is often generated at locations far removed from where it is consumed. An efficient way to transport energy to cities and people are gas-insulated transmission lines (GILs). Siemens is the technology leader in the field of GILs. They are suitable for direct and alternating electricity and can be laid both above and below ground. Their transmission loss is up to 70 percent lower than that of overhead lines. As part of the expansion of the power supply network in the United Arab Emirates, Siemens Energy delivered four turnkey high-voltage substations for the “Dubailand” theme park and supplies equipment like substations and gas-insulated switchgear for the expansion of the high-voltage grid in Qatar.
Intelligent energy conservation plays an important role in sustainable city development. A sophisticated energy management system allows utility companies to be more productive while using less energy. This has a positive impact on operating costs and the environment. SIMAIN® Energy Optimization identifies areas for potential optimization in energy management, analyzes potential savings and implements measures for the sustainable reduction of energy costs and CO2 emissions.
Clean water is crucial when it comes to public health and quality of life. And due to the expansion of cities and economic growth, the requirements for the supply of clean drinking water and sufficient wastewater treatment are increasing. Water supply and water treatment therefore present a challenge to megacities and metropolitan areas.
This challenge is becoming increasingly important, especially in arid region like the Middle East. Siemens water solutions can help communities and industry to better manage the use of their natural water resources and support the water demands of the region for years to come in a sustainable way.
For instance, in Saudi Arabia we have provided equipment for a long-distance pipeline for the Shuqaiq Water Transmission System. Several pumping stations transport drinking water at a rate of 400,000 cubic meters over more than 900 kilometers from the Shuqaiq desalination plant on the south-west coast to households in the northern and eastern parts of the country.
I n Bahrain, Siemens partnered with EKIUM to implement SIMATIC PCS 7 automation system for the world’s largest thermal multiple-effect distillation seawater desalination plan at Al-Hidd, ensuring drinking water supply in a notoriously arid country. The Al Hidd plant provides drinking water for 75 percent of the country, and a highly efficient, reliable system was necessary.
Siemens offers the largest selection of water and wastewater 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.
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.
Green buildings require an efficient infrastructure, accurate information management and continual real-time maintenance. Combining these requirements can reduce the facility’s greenhouse gas emissions, improve indoor air quality and maximize efficiencies. With Total Building Solutions (TBS) Siemens integrates all systems that are part of the building services infrastructure, such as air conditioning, ventilation, climate control, access control systems, video surveillance, burglar and fire alarms and evacuation systems. It provides greater convenience and improves safety and security for people and assets. Buildings become simpler to run and function more reliably – at lower cost. For a reliable and safe power distribution in green buildings, Siemens Totally Integrated Power (TIP) provides all the necessary support, from the planning stage onward.
The 200 meter Tornado Tower, in Doha, Qatar is a prime example of Siemens’ technologies creating green buildings. Siemens’ Total Building Solutions team implemented the Siemens Building Management System (BMS), which allows for easy operation and monitoring of the entire building. Unnecessary energy use can be monitored, and in turn, measures can be taken to reduce consumption, meaning resources and costs are saved, and CO2 emissions reduced. The integrated solution can reduce energy consumption by 20 percent, and the building, located in Doha’s West Bay, has become a beacon for energy efficiency in buildings.
Siemens integrated a holistic security concept into the building management system for the luxury hotel Atlantis, The Palm, located on the man-made palm-shaped island of Jumeirah in Dubai. Security management solutions range from guest identification to surveillance of the front desk, all entrances and access roads. The system automatically sends a text message (SMS) to the responsible hotel staff member whenever a critical alarm occurs.
Lighting alone accounts for almost 50 percent of a building’s energy consumption. The innovative OSRAM lighting systems are fully compatible, save energy and money and actively contribute to protecting the environment. The new stars in lighting systems for buildings and homes are LED. The highly efficient Osram LED lamps last much longer than conventional incandescent lamps and consume 80 percent less energy.
