Stakeholders

  • Owner : Brussels Airport Company
  • Architect and engineer structure: joint venture CTHM (Chapman Taylor - Buro Happold - Moss)
  • Engineer technics : Technum Tractebel
  • Engineer acoustics : Bureau De Fonseca
  • Technical control : AIB Vinçotte International
  • Safety Coordinator : AIB Vinçotte International
  • Contractor structure, roof, façades, finishing : joint venture CEI De Meyer – CIT Blaton


Basic design principles

  • Create a one-roof-terminal with improved, optimized and centralized operational airport processes (security screening, border control, …)
  • Very illuminated and open building with a maximal view on tarmac and airport-related activities, high internal free height public zones (from 6 to 13m)
  • Very high energetic performance of the building
  • Building calculated to resist aircraft jet blast in combination with strong wind load
  • To be constructed next to existing tunnel, connecting on all levels to Terminal and Topaz


Driving/determining factors for the architecture/shape of the connector building

  • Minimize/avoid radar and ILS impact/reflections by shaping both building façades
  • Existing height/level differences of sloping tarmac level with
    • a 2,7 m difference between Terminal and Topaz
    • 7 m height difference between check-in level and gate level for the in pier A departing passengers
  • North South orientation of the new connector building resulting in
    maximal daylight entrance throught north facing roof windows
  • maximal protection to solar heating by shaping east and west façade
  • Taking into account existing underground passenger tunnel currently connecting Terminal and Topaz (current
    passenger flows)


Functions per level

2nd floor

  • Access control Pier A and B
  • Security screening Pier A and B
  • Circulation for departing and transfer-passengers
  • Central border control for Pier B
  • Mezzanine intended for hotel and catering industry

1st floor

  • Commercial zone for Pier A
  • Zone for baggage reclaim

Apron level

  • Reserved area for offices, archives and spaces for activities which require immediate access to the apron
  • Technical areas
  • Passage for departure
  • Zone for baggage


Energetic en technical aspects

  • Maximal use of natural (zenithal) daylight coming in trough north facing windows in roof segments to minimize electricity consumption without overheating impact (1500 m² of glass roof panels)
  • Optimal protection to solar gains by (different) treatment of east and west façade
  • Very high level of thermal insulation of the building (K20)
  • Installation of HVAC system with maximal energy recuperation
  • Rainwater tank constructed under the building for water recuperation (670,000 liters)
  • Maximal use of LED lighting to reduce electricity consumption
  • Acoustic insuation against outside noise level of 85dB(A)
  • High level of internal acoustic characteristics to obtain high comprehensibility of spoken informative messages for the comfort of passengers (400 speakers)

Facts

  • Building will be on both Zaventem's and Steenokkerzeel’s territory - municipal boundary runs under building
  • 15 m wide / 90 m long wing element will be constructed in steel to cover the zone with screening machines
  • building fully compliant to be equipped with geothermic energy balance system for heating and cooling in thefuture
  • A 4-lane wide underpass with a 4.5 m free height is provided to enable all service vehicles to drive from one side of the building to the other with passengers moving above.
