The NIRON PPR system was installed for the renovation of the offices of the Tour Paradis, the 118-meter (136-meter including the antenna) skyscraper also called the Tour des Finances built in Liège in Belgium. The Tour Paradis is an administrative center especially designed for the Liège regional Federal Public Finance services, to centralize jobs of more than 1.100 people in an optimal way. The building and its plaza were designed also as a gateway to a new district Paradis Express to be built in the coming years and which will create a pedestrian urban link between the river and the new railway station designed by Calatrava. Technically, the Tour Paradis is exceptionally innovative and very advanced concerning sustainability – it is comprised of glassed façade incorporating photovoltaic cells, LED lighting system as well as thin vertical metal elements adding rhythm to the vertical urban gesture. Rainwater is being collected and used for the sanitary or maintenance of the exterior parking areas. The cooling equipment provides cooling production with a high performing ratio of 7.9 when fully running. As a result, Paradis tower has received BREEAM “Excellent” certification. BREEAM is the world’s leading sustainability assessment method for masterplanning projects, infrastructure and buildings. It recognises and reflects the value in higher performing assets across the built environment lifecycle, from new construction to in-use and refurbishment.
