AirDeck® - Energy and resource efficient floor system
AirDeck® is a new, patented floor system that is creating a true revolution in the construction industry. It reduces construction costs and increases efficiency in all sorts of multi-storey building projects - car parks, apartment buildings, office buildings, industrial & utility structures, and many more others. This monolithic floor system with bidirectional load-bearing capability is based on a framework panel fitted with an array of robot-placed airboxes, which are weight-saving hollow elements. The airbox structure is sufficiently rigid to firmly anchor them in the concrete without drifting. The airbox structure is also designed to resist very high point loads in order to minimise the possibility of damage at the construction site.
The technique is an ingenious example of applied technology. All the base reinforcement is placed on top of the framework panel. The lattice trusses in the bottom shell serve as lifting points, stiffen the shell during handling and installation, and provide perfect bonding with the cast-in-place concrete. Fully computer-controlled production allows units to be made to measure. This makes them extremely flexible with regard to design and configuration and allows all your wishes regarding cut-outs and cast-in elements to be accommodated. In addition the material has a high level of fire resistance.
Hollands Huys was built with the promotion of city of Hasselt as an example of using the AirDeck® technology (Hasselt Municipality, 2010). A maximum energy efficiency, comfort, ergonomics and aesthetics were the guiding principles for the design of the Hollands Huys. The concept of the building took into account the orientation of the building and a high degree of isolation (both walls and the roof). The heating and cooling system that uses water at low temperature for the entire mass of the concrete to warm up / cool down. (Maximum 26 ° C for heating and minimum cooling to 19 ° C). Overall, the building uses 90% less energy than the traditional house of similar scale. The result is a building with an E level of 49 and a K-22 level.

Drivers are the extra investments compared to a building with a level of E-100 is minimal; in a few years time they can be recovered by high energy profits; cost savings in transportation due to the light weight (fewer crane motions, reduced transport and faster placement combine to yield more effective utilisation of available resources and manpower); possibility to combine with heating and/or cooling system; pipes can be incorporated in the floor to provide a constantly pleasant temperature without the draw-backs of air conditioning systems.
Barriers are lock-in in conventional technologies and their dominance in the national construction market; dependence on the input material like propylene
The Air Deck® floor systems need around 30% less steel and concrete, which also means lighter foundations and supporting walls. Beams and column heads are unnecessary, so thinner floors can be built. Less cast-in-place concrete per storey and using fewer columns and beams can reduce the total weight of the structure by as much as 50%. It is however just as strong as conventional concrete floors, and it can support loads in two directions. Larger free spans and lower weight produce a more stable structure with reduced probability of hairline fractures.
Fewer crane motions, reduced transport and faster placement combine to yield more effective utilisation of available resources and manpower.
The airboxes are made from recycled polypropylene. They do not adhere to the concrete and can be recycled.
Heating and/or cooling pipes can be incorporated in the floor to provide a constantly pleasant temperature without the draw-backs of air conditioning systems.
The Hollands Huys project proves that the extra investment compared to a building with a level of E-100 can be minimal, and can be recovered by high energy profits in a few years time. In cash terms, this means a monthly cost of 0.11 euro per square meter compared to 1 euro per square meter for a traditional building (E100). It also saves 110 tons of CO2 per year.
