FACADE

A thermographic inspection of the complex reported near-zero heat losses.

  • Masonry - Wienerberger, Porotherm Clay Block Walling System
  • HT-coated facades - Agrob Buchtal, Hydrophilic Tile ceramic coating with self-washing effect
  • Alucobond non-combustible aluminum composite panels Class A
  • Limestone

PLASTER WORKS

  • Gypsum and lime-cement plaster Knauf-MPI25 for machine application

INSULATIONS

  • Facade thermal insulation - Rockwool mineral wool, thickness 15 cm
  • Roof thermal insulation - FIBRANxps extruded polystyrene panels, thickness 20 cm
  • Soundproofing – Copersound, Italy
  • Waterproofing - SBS waterproofing Polyelast Extra, Czech Republic

WINDOWS

The technical characteristics of the windows and frames are determined based on a 3D model, taking into account the actual location of the complex to avoid reflective glare on nearby buildings.

  • Shopping Centre - facade system: aluminum frames Schuco FW 50+, cable-stayed structure "spider" system
  • Shopping Centre - “Sky Light” roof glazing produced by Schuco
  • Residential and office areas - aluminum system Schuco series AWS / ADS 70.HI with the highest degree of thermal insulation

GLAZING WITH AGC GLASS

  • Aluminum doors for apartments and offices produced by Schuco
  • Fire-resistant steel doors produced by Novoferm

FLOORING

  • Shopping Centre and stairs - granite from Brazil
  • Offices – fine stoneware tiles from Italy

PANELING

  • Shopping Centre and stairs - limestone
  • Offices - fine stoneware tiles from Italy

ROOF WORKS

  • Pitched roofs covered with copper sheathing
  • Flat roofs lined with clinker tiles produced by Agrob Buchtal

SOLAR PANELS AND SYSTEMS

  • Installed solar panels Eco Focus produced by Innotech Solar

ELEVATORS AND ESCALATORS – OTIS GeN2

This technology is up to 50% more energy efficient than conventional elevators and escalators. Regenerative drives ReGen™ increase efficiency, reducing energy consumption by up to 75% through energy conservation and returning it back into the grid - circuit of the building.

WATER SUPPLY & SEWERAGE SYSTEMS

Sewerage system – cast iron pipes, Wilo pumps, Geberit structures, etc.; resistant to microorganisms, mold and atmospheric influences. The pipes are fire resistant and 100% recyclable.

  • Soundproof installation shafts
  • Reservoir for domestic water supply and split systems for discharging domestic, rain and condensation waters.

The water supply system has two additional filters:

  • UV - FILTER which serves for disinfecting water flowing through it by means of UV lamps.
  • MECHANICAL FILTER (100 microns) which purifies all water facilities and prevents them from clogging.

Individual measurement of water consumption for each of the premises is provided.

The water pipes are coated with aluminum layers.

HVAC SYSTEMS

  • Air conditioning - DAIKIN air-to-water heat pumps for the residential area and TOSHIBA three-pipe VRF freon systems for offices, shops and restaurants
  • Hot water for the public sector is provided by high-temperature heat pumps Carrier. Domestic hot water for the residential section is produced by boilers which are integrated into the indoor units of the heat pumps.
  • Ventilation is filled with highly efficient air conditioning cameras DamVent with a first step - recuperative heat exchangers and secondary recovery by heat pumps in the channels of the treated air.

POWER SUPPLY

The complex has an installed electric capacity of 4 MW, the power supply is ensured by two substations. Reservation of power is carried out with two diesel engines with a capacity of 900 KW.

  • trays with overcurrent protection.

LIGHTING

  • Philips LED lighting fixtures

EMERGENCY AND EVACUATION LIGHTING

  • Central battery and lighting system for testing the preparedness of each lighting fixture
  • Emergency lighting on the evacuation route, hydrants and exits provided to enable swift and safe evacuation of the building
  • LED evacuation lighting - RP-Technik

ICE AND SNOW REMOVAL SYSTEM

  • Provides reliable performance of all systems, unimpeded use of stairs and ramps, thawing gutters, siphons, culverts and terraces, satellite box.

BMS

Schneider Electric Bulgaria delivered and implemented a new platform for building automation - StruxureWare Building Operations (SBO) providing centralized monitoring, control and management of the HVAC system, electrical installations and fire safety of the complex. Furthermore, an energy management system was integrated in all parts of the building.

FIRE SAFETY SYSTEM

  • Bosch fire alarm system for accurate, reliable fire detection and notification

SECURITY SYSTEMS AND CCTV

  • Bosch equipment, all security systems are integrated into a common system for visualizing events
  • Access control

ENERGY EFFICIENCY

During the design and construction of San Stefano Plaza - the first complex in Bulgaria that has obtained Energy Efficiency Class A, the principles of sustainable construction were applied. It was achieved using leading-edge technological solutions, high-quality natural materials and innovative energy saving installations.
