The “representative” office area flooring (not more than 20% of the total office area) is covered with padded carpet of cut pile type with 70% of wool. Toilet areas and the so-called kitchen areas, technical rooms, staircase vestibules and the staircase floors and stairs are covered with ceramic terracotta tiles (gres tiles), abrasion resistant (class V), non-slip, min. 8 mm thick, of CERAMICHE CAESAR or MARAZZI class, fixed on adhesive mortar of ATLAS standard.

The office areas have soundproof suspended ceilings of ROCKFON standard and type C suspension, mechanically attached to the roof construction on adjustable runners of galvanised steel rods The ceiling is comprised of 60x60cm modules, white, of 85% reflectance, acoustic insulation of 21dB, average sound absorption coefficient > 0.70 and relative humidity resistance of 100%. On the entire width of the windows, there are drywall bays for the suspension of vertical blinds. The ceilings in toilet areas and the so-called kitchen areas are made as above with ROCKFON HYGENE panels of average sound absorption coefficient >0.85 and acoustic insulation of 18dB.

Basic parameters: Space utilisation rate: 1 pers/ 8m2 Maximum design temperature in summer: 24ºC ±1ºC when the external temperature is 30ºC Minimum design temperature in winter : 20ºC ±1ºC when the external temperature is -20ºC Relative humidity: 45% ±10% Amount of supplied fresh air : 40 m3 / hour / person The building is fully air-conditioned through a system of 4-wire inductive devices (cooling and heating functions) located under the windows. Ventilation units for floors above the ground are located on the roof, and the units for the ground floor, first floor and underground floors are located on -1 floor. The air is pre-treated, filtered, heated or cooled in 2 units on the roof and 3 ventilation units located in the engine room on -1 floor. Vertical distribution is provided by ventilation shafts located in the central part of the building. Horizontal distribution is provided by ventilation channels above suspended ceilings. Conditioned air is supplied to the office space by inductive devices.. Air-conditioning is adjusted centrally and, additionally, by wall-mounted controllers. Fire ventilation prevents uncontrolled spread of fire and smoke and provides smoke exhaust, which enables effective evacuation of people.

The Office Building is equipped with three passenger lifts by Otis company.

The fire alarm control panel and automatic signal to the State Fire Service, fire detectors in every room, fire damper monitoring and control, smoke exhaust system, alarm signal system, manual call points, pumps, signaling system for concentration of carbon monoxide and sprinkler installation in the car park, fire hydrants on every floor, escape route signs and portable fire-fighting equipment.

Power supply of the building is ensured by a double transformer substation of PZO (delivery-receipt) type, with a 15kV two-section switchboard divided into STEN part and the user part, located on -2 floor. The transformers are able to transfer the entire power load of the building. On -3 floor there is a power generator of 800 kVA and on -2 floor there is central UPS of 360 kVA.

Basic light fittings: 600 x 600 mm, modular, mounted in the suspended ceilings. Emergency and evacuation lighting. Lighting control system: independent for each office room, by Zumtobel. Every workstation is equipped with normal power supply sockets and central UPS sockets.

The integrated computer and telephone installation (structured cabling) comprises cables of 5e category or 6 category of 1GB capacity (to be chosen by the user). The telephone switchboard is Alcatel 4400, and the amount of telephone numbers and specialised services is to be arranged. Every workstation is equipped with 3 RJ45 sockets. Socket sets (RJ45 and power supply sockets) are installed in under-sill trims and in cable posts. Additionally, the structured cabling is equipped with so-called concentrators (installed in between the ceilings) to enable changes in the arrangement of office space. Such horizontal cabling architecture enabled to resign from the so-called elevated floor, which is mounted only in the rooms with high cable concentration, i.e. in server rooms, dealing rooms, etc.
