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:

  • Smoke photo-electronic fire sensors
  • Manual fire indicators with built-in modules installed in emergency exits and escape routes.

The warning system provides the following:

  • Broadcast of local programming (optional)
  • Broadcast of local speech programming
  • Automatic warning and directions for tenants and employees evacuation in case of fire or emergency (in Romanian, Russian and English languages)
  • Organization of announcement area locations - i.e., corridors and offices on each floor, administration rooms, engineering and utility service rooms, boiler room, restaurant and parking areas.

 

 

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:

  • Panoramic surveillance of the building exterior perimeter, including entering and exiting of vehicles from the external, underground and guest parking areas
  • Surveillance of all the entrances to the building and technical/engineering areas
  • 24-hour video recording and archiving.

 

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:

  • Office premises
  • Restaurants
  • Commercial premises
  • Administration premises, utility service rooms, dispatcher room, server room and room of boiler operator
  • Halls and vestibules

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:

  • 24-hour air conditioning maintaining comfortable microclimate parameters by using the combined supply and exhaust ventilation, with input air heating up to +18°С and humidification to 45% in the winter and cooling down to +20°С in the summer.
  • Further air temperature adjustment to comfortable parameters in each separate office is made through 4-pipe fan-coils with individual-zoned settings.

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:

  • Three elevators have a lifting capacity of 630 kg (8 passengers) per 11 stops.
  • One elevator has a lifting capacity of 1,000 kg (13 passengers) per 13 stops, including underground parking and technical floor. This elevator is also designed for transporting fire units in case of emergency and is manufactured from fireproof materials.

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:

  • Automatic set up of the fire alarm and fire alert
  • Automatic sprinkler and water drencher systems
  • Automatic set up of a gas fire fighting module in the premises, where a diesel generator is located

When the fire alarm is activated:

  • The supply-and-exhaust ventilation system automatically switches off
  • The smoke removal system for the floor corridors and underground parking automatically switches on
  • The air supply system for staircases and elevator shafts automatically switches on
  • The voice and light warning system (flashing light strobes located by the loudspeakers near building entrances) automatically switches on
  • Three elevators are lowered to the 1st floor, switch off and the elevator doors are opened
  • The fire alert is passed by radio channel to the main panel of Chisinau fire department

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:

  • Automatic water sprinkler system installed in each room
