Project Lighthouse
Strijp-S - Eindhoven's vibrant and fashionable neighbourhood - gets an eye-catching new building in the 109 metre tall Lighthouse residential tower. SDK Vastgoed is developing the tower on behalf of Spoorzone BV. Stam + de Koning Bouw and Visser & Smit Bouw are the contractors for the work. On the ground floor there will be commercial properties, restaurants and offices; above, a generous 333 apartments spread over 33 floors. Interduct company Rodrie became involved in the project through the installation consultant, and is installing a heat-exchanger ventilation system in each apartment. This way, the residents - who will move in during 2025 - are assured of (pre-heated) fresh air as well as an energy-efficient system.
Building split into two halves
Each apartment will have its own ventilation unit with heat recovery: the Flair 300 from Brink Climate Systems. CO2 sensors in the living room and bedrooms provide residents with demand regulated fresh air. There is a four-position switch in the bathroom, allowing them to manually turn up the ventilation while showering.
The unique aspect of the project, says Rodrie's project manager Berry van Hout, is that the building is split technically into two when it comes to ventilation. In high-rise buildings, the intake and extraction ducts for ventilation normally run to the roof via shafts. Given the size of the residential tower, this would mean huge shafts and air volumes. Therefore, the intake and extraction ducts for the lower half of the residential tower go to the façade via collector ducts above the commercial plinth. They are concealed above a suspended ceiling. "That way, the shaft ducts can remain narrower," Berry explains. "It is the first time we have resolved it this way. The basic principle for this was worked out by the installation consultant, but we added our 'Rodrie touch' to it. That is, we refined and streamlined it."
The power of collaboration
Rodrie was not the only Interduct company involved in the construction of the Lighthouse. In addition, Robé supplied rectangular ducts, prefabricated flat ducts and prefabricated shaft ducts including branches. Materials such as valves and other spiral ducts came from VentTrade. A Rodrie insulation partner insulated the shaft ducts on site. This makes their assembly easier, but it requires greater coordination with the constructor. Compliments for that to the contractor, as far as Berry is concerned. "The schedule was very well planned. Excellent cooperation between all parties was a hallmark of this building."
