Solution
The IMd structural engineer suggested placing so-called panels to span the approx. 5 m between the floors. Consequently beams could be fitted in-between the steel structure, creating a considerable gain in height. They were aware of the smart possibilities the Metsä wooden hollow-core panels could offer.
When using this manner of construction, the floor panels lie between the steel ring girders. In addition to gaining a height of approx. 36 cm, this manner of construction also enables the use of less m². The crux of the placement of these panels lies in the fact that the high quality Kerto® LVL S-ribs are glued constructively to the Kerto® LVL Q upper panel. This creates a strong total to which diaphragm action can be applied. Something that appealed to the IMd structural engineer. The architect acknowledged the rigid structure would guarantee a high level of comfort to the users of the premises.
In addition to the floor construction, with an approx. total height of 390mm, a roof has been erected made of the Finish wooden hollow-core panel.
Results
A sustainable and multi-functional building which can be disassembled and in which the ‘Het Klimbos’ hostel and the nature, environmental and education centre merge seamlessly. The building owes its compactness to a highly implemented double and multiple use of space whereby functions and facilities are shared. Resulting in low building and operating costs on the one hand and a strong synergy between functions and target groups on the other hand.
Imd, together with the architect, made several construction drafts during the design phase regarding sustainability performance in order to attain the lowest ‘overall’ environmental impact. Consequently, the cold-rolled C-profiles were chosen. They are extremely light and use much less material and energy than hot rolled profiles.
Other construction components include wooden laminated beams and wooden, pre-fabricated Kerto® LVL element floors. The wooden rafters from the old, demolished Stayokay will be used to make furniture.
Approx. 20 tonnes of CO2 is stored in the total amount of wood used for the Ripa’s; this is equal to the electricity consumption of 20 households in 1 year (source: NBVT computing module).
