The KONE Polaris™ Destination Control System (DCS) was chosen for Tour First to fulfil an ambitious refurbishing project.
Tour AXA, originally built in 1974, is located in the heart of La Défense, the business district of Paris. After three decades, the building was stripped down and a new tower, renamed Tour First, was designed and constructed around the old metal framework. All this was achieved in just four years.
The site is in the middle of the busy business district with no easy access and with minimal on-site storage. We used a vertical storage method to reduce the area needed for the equipment and carefully planned the installation tasks.
Because the new building would use the same lift shafts, another solution had to be implemented through means other than adding new lifts. KONE installed the KONE Polaris™ Destination Control System, which uses intelligent assessment of vertical travel needs based on the floor selections of users to minimize the number of stops and optimise the vertical flow in the building.
The KONE solution delivered excellent eco-efficiency while nearly doubling the number of people who move throughout the tower.
