The Moscow International Business Center (Moscow City) is one of the world's largest business district projects with over 3.5 million meters of floor area. The IBC will be one of the largest, tallest and most dense skyscraper clusters in Europe. The project is intended to be the core of the future modern center of Moscow. The "Big City", over 1,000 hectares, is estimated to cost over $100 billion to build.

The $10-billion "Moscow City" complex of offices, hotels, apartments, restaurants, shops and entertainment centers will have about 25 high-rises, including at least seven buildings taller than any others now existing in Europe. Dominating the site will be the 612 meter tall Russia Tower, which will be one of the tallest buildings in the world. It is due for completion in 2012. Most of the rest of the center is to open in 2009 and 2010.

Skyscraper Russia Tower

Based on a geometry derived from a triangular plan with an open "green" spine, the building's primary structure comprises three "arms" that taper as they rise. They create a slender pyramidal form that achieves maximum stability with the minimum structure, and allows the most effective distribution of space. The higher floors containing residential and hotel accommodation are designed as a series of modular units that can be configured individually. At the summit, a public viewing deck with cafes and bars creates an attraction for visitors and residents, while an ice-rink and shops add to life at street level. The environmental strategy harnesses a range of passive techniques and controls. Strategically, mixed-use offers a strong starting point, allowing energy balance throughout the day as people move between office and home. Structurally, the tower's slender profile creates shallow floor plates that maximize daylight penetration and increase the potential for natural ventilation. The triple-glazed, high-performance facade reduces heat loss, energy recycling reduces heating demand by 20 per cent and snow and rain water harvesting is expected to cut fresh water consumption for toilets by a third. Thus, socially and environmentally, Russia Tower offers a sustainable new solution to contemporary living.

The North Tower

The North Tower is an A class office complex located in the Moscow International Business Center. The North Tower is the residence of the world's famous companies such as General Electric, IBM, Eli Lilly, P&G, Lucent Technologies, Bunge and Nortel. The building has excellent natural light, large atrium and panoramic elevators. The complete building is equipped with furniture made of high-quality materials. Perfect heating and air-conditioning is provided by 204 HVAC systems. The building is also equipped with a multi-level parking system for 688 car spaces. The visitors can relax in the swimming pool, fitness center, cafeteria, bar or in the restaurant. The building has its own conference hall and bank branch with ATM machines. The North Tower has 27 storeys. Its construction began in 2004 and finished in 2007. The North Tower was designed by Project Institute 2 and developed by Strabag AG. The owner of the building is Severstal Trans.

North Tower HVAC control system

During the years 2006 through 2008, a new HVAC control system was implemented by a Slovak company, Sauter Building Control Slovakia s.r.o. The HVAC is controlled by Sauter EY3600 PLCs. The fire dampers are controlled by DI modules manufactured by ICP CON Company. Monitored and controlled are also:

  • air-conditioning units
  • heat exchanger stations
  • cooling units
  • air curtains
  • lighting
  • fire ventilators
  • fire sprinklers
  • fire dampers
  • Electronic Fire System
  • Other data (garage flooding, temperature of transformer stations)

To monitor the above mentioned devices and systems, the Reliance 3 SCADA/HMI system was installed in three control rooms. The first two allow for the monitoring and control of all air-conditioning units (sections North Tower 19-1 and North Tower 19-2), the third allows for monitoring the Electronic Fire System. The control rooms are connected to the Local Network. In the North Tower, Reliance provides the following:

  • real-time monitoring and control
  • logging data
  • logging alarms/events
  • trending
  • reporting
  • communication with OPC servers

The control system is composed of three parts. Each part has its own communication bus for reliable communication with the control rooms. The first part provides control of the air-condition units, heat exchanger stations, cooling units and lighting.

The second part provides control of the fire ventilators and fire sprinklers. In order to achieve high data reliability, the second part is separated from the line which is used for communication with air-conditioning controllers. The fire ventilators are controlled by PLCs with a fire matrix. The whole building is divided into several fire zones which are automatically controlled by the Electronic Fire System. The first two parts communicate over the NovaNet serial bus. The control rooms are equipped with NovaNet/Ethernet converters.

The third part provides control of the fire dampers using the I-7053 Digital Input Modules. Communication with these modules takes place over a RS485 serial line and the data wiring is connected to a RS485/Ethernet data converter.
