Next to the heavily renovated Gateway building on Brussels national airport, a new offices building is being realised. Passport consists of 2 L-shaped wings, encircling an atrium. Besides 8 floors of offices, the building also contains a restaurant, fitness facilities and archives. Tenants have the use of 361 underground parking spaces and 73 bike stations.
The design shows great flexibility, optimising it for a multi-tenant context. The 1,655 sqm floor surfaces can easily be divided into 2 independent areas. One wing will be occupied by consultancy firm KPMG. Microsoft is another tenant.
The sustainable approach of the development aims for a BREEAM “Very Good” assessment. Much attention is paid to optimal airtightness, amongst others through a well thought-out detailling of the window connections, and a high-quality thermal glazing with solar protection. Also, the offices are heated and cooled with climate ceilings. However, no heat is produced on site: hot water is provided by the airport’s hot water network. For cooling, free chilling and free cooling is applied. Rooms that are not continuously occupied (meeting rooms, auditoriums), use demand-driven ventilation. Optimal daylight access, combined with energy-efficient TL5 lighting and daylight control in offices and meeting rooms, considerably reduces the electricital consumption for lighting.
