Heavy current and low-current

  • A separate distribution centre will be installed in each rental area.
  • Each rental area is equipped with remotely read electric and heating meters.
  • Workplaces are equipped with sockets and network sockets.
  • Each workstation has 2 low-voltage sockets in addition to the heavy current sockets. The network cable is installed in accordance with the Cat6 requirements. Rental premises can receive TV signal via data network over the Internet.
  • The whole network of communications of the whole floor is ensured via networking cables that are located in the technical space of the rental area and from there, they are taken to the communication room of the building. The communication room has cooling.

Workstation equipment

  • There are 2 workstations and each has 6 heavy current and 2 low-current sockets. In the workplace, the sockets are grouped in a 4+2 system, where two sockets are equipped with UPS power supply.
  • Plugs used for household activities that are up to 30 cm high are located under the light switches in the rooms and cleaning plugs are located in accordance with the norms (at a distance of approximately 10 metres).
  • A mini-kitchen can be installed in the kitchenettes as there are 6 heavy current sockets.
  •  Heavy current power supply plugs can be used in the computer network server cabinets and floor distribution boards. Feeding devices can be connected to the UPS network. The central UPS device is purchased by the tenant if necessary.


  • The type of the lights is specified in the renter's project.
  • The lights are equipped with electric ignition devices and monitor optics.
  • Light intensity is guaranteed in accordance with the established standards.
  • The emergency evacuation light is installed in accordance with the renter's project and designed in accordance with the established standards.


  • There will be a central forced ventilation with a heat exchanger. The air-condition in office rooms is 2 l/s*m2 and in meeting rooms 4 l/s*m2.


  • Heating is ensured by heat exchangers based on district heating. Factory-painted radiators or convectors are used as heaters. The thermostats of the heaters are equipped with electric actuators so that they operate in coordination with cooling.
  • The calculated internal temperature in the winter is +22±2°C, and the moisture is not controlled separately.
  • Each rental area has its own remotely read heat meters for radiator heating. Additionally, the hot-air heaters of the central ventilation units of the commercial premises are equipped with remotely read heat meters.


  • The cooling system ensures that the indoor climate of all surfaces and rooms is consistent with Class II of the indoor climate.
  • Cooling solution: the supply air for the ventilation is pre-cooled (cooling calorifier in the ventilation unit), plus Fancoils. The cooling intensity can be adjusted from the wall of each cabinet. The technical rooms on the office spaces are equipped with cooling.
  • The condensate water from the cooling system equipment is discharged into the sewer. Fancoils are connected to the electrical shield of the rental area.

Water and sewage

  • Two adjacent toilets are built, both with one toilet pot and a sink with a mixer.
  • The rooms are equipped for a kitchen corner and the piping is finished with blind flanges.


  • To control and manage technical systems, a digital (i.e. computer controller) control and surveillance system or BMS will be built. The heating, cooling, lighting, and ventilation systems of the building is controlled by automation, based on the actions and values provided by the programmes, changes in external weather conditions, and energy saving principles.
  • The system also enables monitoring and recording errors in the operation of technical equipment (indoor climate sensors, heating unit, outdoor lighting, fire safety equipment, alarms, etc.).

Fire safety

  • A fire alarm system is installed in the building in accordance with the regulations in force.
  • The fire extinguishers, hydrants, fire alarms, sensors, signage, and emergency lighting are designed in accordance with the current norms.

Access system and security alarm for office premises

  • The system consists of module-extensible security alarms and a control device-extensible, computer-assisted access system.
  • The security alarm system used allows the user to set up various security programmes (including cleaner, manager programmes, etc.).
  • The security alarm system is equipped with autonomous battery devices.
  • The security alarm system covers all premises of business entrances and potential attack areas. Magnetic contacts and passive motion sensors are mainly used as sensors. Access doors to different areas are equipped with magnetic contact sensors.
  • The system is adjustable from LED keypads. The keypads are installed at the entrances to the rental premises.
