Challenging Energy Savings in High-Rise Buildings with Limited Space

Designed in 2008 with a full-glass facade, this stylish 42-storey municipal office building lacked floor space for installing air cooled condensers. The initial design called for a chiller system, but learning of Daikin’s space-saving designs and energy efficiency systems the owner approached us for a consultation. We recommended a water cooled VRV system using cooling towers with outdoor units housed inside the building. After many rounds of meetings, proposals, and further improvements, the owner became convinced Daikin offered the optimum solution to his needs.
