Ingenium developed a technical concept in which flexibility and energy efficiency go hand in hand. The core principle: dual and distributed systems. This means that each floor can be controlled separately and that spaces can be easily adapted to new functions without affecting the rest of the building. Up to four different companies or departments can operate on each floor with complete autonomy.

A central core houses elevators, flanked on either side by two large vertical shafts running the entire height of the building, within which the technical ducts, pipes, and cables have been concealed. If the air handling units were to be installed on the roof, these shafts would have to become progressively larger as they rise through the building, resulting in a significant loss of space on those floors. For this reason, floors 4 (entirely) and 12/13 (partially) are reserved exclusively for technical systems. Since the top three floors are currently being constructed as shell spaces, the technical systems are designed modularly. All ducts are in place, and branch connections can be made according to the future use of the spaces.

Due to its height and location, Nobel I is a striking feature of Ghent’s streetscape. During the design phase, particular attention was paid to the visual interplay between architecture and building systems. When it is dark outside, the lighting inside the building is always beautifully aligned, regardless of the floor or the intended use of the spaces. We handled the complex coordination of the positions of ventilation grilles, sprinklers, and other technical systems with those of the ceiling lighting. For example, the ducts are cleverly integrated between the windows, allowing the facade to maintain a clean and uniform appearance without visible grilles. This design principle combines functionality with architectural unity.

For the energy supply, Ingenium designed a fossil-free system without a gas connection. Heat pumps capture outdoor air and distribute heat and cooling through distributed HVAC systems. An electrical backup and a building management system (BMS) ensure reliability and efficiency. PV cells were integrated beneath the window openings and serve a dual purpose: they provide green electricity and act as passive sunshades. Above the windows, additional sunshade elements contribute to thermal comfort and the aesthetics of the facade.

Ingenium integrated hygiene and safety into every aspect of the design. To avoid Legionella risks, traditional hot-water recirculation systems were not used. Instead, instantaneous water heaters provide immediate heating of water at the point of use. For areas with cleanroom requirements, technical components were strategically placed: heavy equipment is located beneath the cleanrooms, keeping pipe lengths to a minimum and limiting negative effects on air handling.

Fire safety is based on an innovative compartmentalization system with advanced sprinkler systems that meets U.S. insurance standards.  

Also not uncommon in this project is the graywater recovery for the toilets in the central core that are accessible to everyone. Indeed, the roof is too small to recover enough rainwater. In the other areas of the building, hygiene standards are much higher, and to avoid contamination with the research and development activities, city water is used for toilet flushing.
