“Which cooling system is most effective with a suspended metal ceiling?” This was the question posed by the engineering firm commissioned by UBS in 1995 to define the building technology for its headquarters in Fribourg. After a comprehensive analysis, our KIGO panels were awarded the contract. And when we ask ISS, responsible for building maintenance at UBS, the same question today after more than 20 years of operation? “The KIGO chilled ceilings require no maintenance and are still as good as new after 20 years. An excellent system!” We were delighted to take up the challenge and implement an economical, efficient and sustainable solution.
