SKYTOWER is equipped with the following communication and alarm systems that meet the standard technical requirements for office buildings:
To ensure the highest efficiency and most reliable maintenance for the building, engineering systems have been created using the latest technical equipment available from leading international manufacturers. All communication, television and alarm system cables are replaceable and laid in inset devices such as troughs, plastic pipes and metal hoses.
In order to facilitate office computer network setting up outlets for computer network connections have been mounted next to the telephone outlets. The cables for these connections are hidden under the suspended ceiling, making the work area less cluttered and setting up computer connections and computer equipment more flexible.
A high-speed Internet (1Mb/s) connection is supported by fiber cable.
In Business Centre an automatic telephone station has been installed. Offices have a city telephone line connection, with one phone number per workstation. Each office has one telephone connection outlet as well as a telephone connection to the business center’s engineering and utility service rooms.
Television and radio connections are available in each office on all the 11 floors.
Television system is connected to the local cable provider.
The access control system enhances security of SKYTOWER and controls the access of tenants and employees to the building (including engineering and utility services rooms), as well as vehicles’ entry and exit.
According to Category B of the local fire safety regulations, fire detection equipment in all premises is including the following:
The warning system provides the following:
The intruder alarm system is built on the control panel basis, with movement sensors installed in the secured rooms. The alarm button is also provided for at the security post.
The video surveillance system provides:
The air conditioning of the office premises is based on a 4-pipe system produced by Wesper, a worldwide manufacturer. The air conditioning system functions on the “chiller-“fan-coil”- conditioner” principle that is used for the following types of space:
The sources of cold are chillers, the two low-noise cooling machines manufactured by York (Great Britain), with productivity of 783 kW each, which works only on cooling. The fan-coils are channel-type conditioners embedded in the suspended ceilings in all the air conditioned premises. All pipes conducting cold to the fan-coils have heat insulators. In addition, to reduce the noise produced by the ventilation and refrigeration systems, special measures like having a resiliently supported base, sound insulation and sound dumpers have been taken.
The parameters of the air conditioning system are designed to provide comfort, namely:
Recuperation sections of the combined supply-and-exhaust ventilation system help keep energy consumption low.
All the elevators have been selected to provide an efficient functionality and operation, corresponding to the modern business centres.
Number of elevators was calculated to ensure an optimum flow of people during peak hours.
SKYTOWER has 4 elevators from OTIS(France), the world’s leading elevator manufacturer:
In case of fire, all elevator shafts are pressurized to prevent smoke penetration.
All elevators are equipped with communication system connected to the technical staff.
The speed of elevators’ cars varies between 0.8 and 1.5 m/second, and depends on the number of passengers and height of lifting.
International Business Centre SKYTOWER is equipped with an analogous fire alarm system coordinated from the main panel and includes: smoke and heat detectors, manual fire alarms with safe glass and fire detectors behind suspended ceilings.
The building’s fire alarm system consists of three components:
When the fire alarm is activated:
Fire alarms have indicators for both normal and alerting states. Once the fire alarms have been activated, the main panel displays the location of the fire and smoke expansion.
The building has the following fire fighting equipment:
The boiler room has a drencher type of automatic fire fighting system, and the diesel-generator room has a gas suppression type of system.
To ensure maximum comfort and uninterrupted heating during the winter time, SKYTOWER’s boiler room is equipped with three boilers manufactured by Buderus (Germany). The intelligent control system can adjust the temperature of the heat carrying agent according to the outside temperature, time of the day and day of the week.
For a more efficient power supply, a separate substation with two transformers (630 kWa each) has been installed in the building. For a continued and uninterrupted power supply, a generator has been installed for automatic activation of reserve power.
For enabling a special group of power consumers in case of emergency (evacuation and emergency illumination, indicators of exits and fire cocks, systems of fire and intruder alarms, automatic firefighting, access control, smoke ventilation, elevators etc.), a Wilson diesel generator (175 kWa) has been installed, which is automatically activated when voltage is lost at the transformer substation.
Power supply to each floor is provided from electrical units by two independent copper cable lines.
The staircases and escape routes are equipped with automatic emergency lighting. The emergency indicators are powered by rechargeable batteries (with the durability of 3 hours).
All cables are isolated with a coating that is nonflammable and does not emit any halogen substances when burning.
The main and switch cable lines of collectors ensure the building’s functioning in case of a fire. The cables are nonflammable and resistant to temperatures of 750 degrees for 3 hours.
The building is equipped with the following types of artificial lighting:
Electric lighting in the offices is provided by Philips lamps with luminous tubes of 4×18 W each and illumination of 300 Lx. The illumination of corridors, elevator halls of the floors 2—11 and staircases is combined and provided by lamps with luminous tubes and point halogen lamps, with energy saving lamps used for the entrance hall on the first floor.
Office power usage is recorded regularly by electricity supply meters.
The building is equipped with a mechanical supply and exhaust ventilation system that consists of air-supply plants located in technical premises and includes: air intake with heat-insulated valve and flap, air filter, heating chamber and air cooler, ventilator, sound dumper, as well as automatic control of air parameters and anti-freezing thermo-elements control.
The ventilation system is equipped with modern filters for coarse and fine air purification. The exhaust ventilation system in offices and common areas is equipped with low-noise aggregates
The ventilation of the underground parking garage has a separate supply-and-exhaust system with sensors for carbon dioxide and methane that are connected to the main system controls.
In the event of a fire, the building is equipped with a smoke removal system that activates automatically and shuts down all the other ventilation systems. All technical areas that contain ventilation equipment have been soundproofed.
The ventilation system provides constant air refreshing as follows:
The following water supply and sewage systems have been installed in building:
Building’s water supply comes from the city water supply system through two separate inlets. A step-up pumping station, manufactured by Wilo, has been installed to provide the necessary water pressure in the service water supply system and for the fire fighting water piping. This system also contains a mounted ultraviolet water disinfection device and a mechanical water fine filter.
All water supply and sewage systems are produced by famous companies from Germany.
