|  21  2012 AnnUAL REPORT Otis elevators, escalators and moving walk- ways are the innovative systems of choice  for some of the largest and most ambitious  building projects around the globe.  During the year, its United Kingdom business  was awarded the largest contract in its history   —a 30-year contract to install, maintain and  modernize 107 escalator units for the London  Crossrail, a new high-frequency railway sys- tem and Europe’s largest construction project.  Work is scheduled to begin in early 2013.  Otis businesses will supply 208 energy-  efficient Gen2 and Sky series elevators to the  Castle Jiujun project, a more than 7.5-million- square-foot ecological and livable community  in southern Harbin, China. Also in China, Otis  companies will provide 299 escalators and 50  elevators to the Hangzhou Metro Line 2, one of  the country’s new, high-speed rail systems.  Otis continues to be a part of some of the  world’s most iconic buildings. Its company in  Brazil will install 21 elevators and escalators  in Rio de Janeiro’s famous Maracanã Stadium,  site of the 2014 FIFA World Cup final champi- onship match and the 2016 Summer Olympics  opening and closing ceremonies. The com- pany also is assisting with the modernization  of the Sydney Opera House in Australia, one of  the world’s most distinctive buildings.  Otis companies are building a number of factories to meet growing demand. During  the year, Otis companies opened the seventh  factory in China and began expansion on a  factory in Bengaluru, India. In 2013, the com- pany will open a 423,000-square-foot facility in  Florence, S.C., which will be its main manufac- turing center for U.S. and Canadian operations.  Another factory is under construction in Brazil.  Otis Elite service is a key differentiator for the company. Using innovative, Web-based  technology, it offers customers an unprece- dented level of support and benefits that help  ensure maximum equipment reliability and efficient repairs of their elevator systems. Otis Elite service subscriptions were up 25 percent from 2011.  The Otis regenerative drive continues to set  the standard for innovation and performance.  When used on elevators, it captures energy  once lost during braking and returns it to the  electrical grid, providing up to 75 percent  more energy efficiency. UTC Climate, Controls & Security delivers  solutions to customers worldwide from leading  brands such as Carrier, Automated Logic,  Lenel, Chubb, Det-Tronics, Edwards, Fenwal,  Interlogix, Kidde, Marioff and Supra.  During the year, the company sustained  momentum from the completed Carrier trans- formation, which began in 2008 to simplify  the business and concentrate on core growth  platforms. The company also focused on  improving and transforming its fire and security operations.  Numerous product innovations were  introduced in 2012, including Kidde’s new  Worry-Free line of smoke alarms. Equipped  with a 10-year, sealed-in battery, the alarms  address customer complaints of low-battery  chirps and fire industry concerns about  missing or dead batteries in alarm units.  Carrier Transicold introduced ecoFORWARD  technologies in advance of U.S. Environmental  Protection Agency diesel emission standards,  which went into effect January 1, 2013. Trailer  refrigeration systems with ecoFORWARD  technologies consume significantly less fuel,  operate more quietly and deliver improved  performance, all while running cleaner than the  models they are replacing.  from OnGuard’s strong integration capabil- ity and increased functionality. Deployed in  transit vehicles around the world, Interlogix’s  Mobileview is the first and only mobile sur- veillance solution to be designated Qualified  Anti-Terrorism Technology by the U.S.  Department of Homeland Security.  2012 marked the 500 th  installation of Carrier’s  CO$_{2}$OLtec refrigeration system, this one in a  new Famila market in Friesoythe, Germany.  Carrier’s CO$_{2}$OLtec installations across Europe  reduce carbon dioxide equivalent emissions  by 137,100 tons, equal to taking 37,200 cars off the road. Carrier also won its largest order  in Saudi Arabia during the year with a contract  to supply and install large chillers to cool King Saud University.  Automated Logic will provide the building auto- mation system for The Tower at PNC Plaza, a 32-story office building under construction  in Pittsburgh, Pa., that is expected to exceed  LEED Platinum standards and become the  world’s greenest skyscraper. The system will  provide a comfortable environment for the  building’s occupants through control and monitoring of heating, cooling and many third-party systems.  UTC Climate, Controls & Security reached  a number of milestones in 2012. Several  Carrier products achieved breakthrough  energy efficiency: Among them were the new  WeatherExpert packaged rooftop unit, the new Infinity 98 gas furnace with Greenspeed  intelligence and the Evergreen 23xRv chiller  with Foxfire compression, which set a new record for chiller efficiency. Carrier  Transicold’s NaturaLINE and PrimeLINE container refrigeration units were validated by UL Environment as having 95 percent and  93 percent recyclability rates, respectively, the only container refrigeration units in the  industry to achieve recyclability validation.  Lenel introduced OnGuard 2012, the latest  release of its industry-leading security  management platform. Customers benefit  Supra won six contract renewals to supply  iBox products to real estate associations  throughout the United States. Five of the contracts were for the new iBox BT, a real  estate key box that can interact with Bluetooth smartphones.  01 Carrier’s AquaForce 30XA chiller is designed  to meet the efficiency demands of today and  the future.  02 UT Electronic Controls, which designs,  sources and manufactures microproces- sor-based controls, is the first electronics  manufacturing facility to receive LEED Gold  certification for existing buildings. 03 Customers no longer have to worry about  replacing smoke alarm batteries. Kidde’s  new Worry-Free line of smoke alarms comes  with a  10 -year, sealed-in battery.
