The air conditioning of the building is implemented using decentralized FSL under floor units (air supply type) (see photo on left). Using these devices, outside air in the façade gap is sucked in, conditioned and directed to the interior. Air arrives through doors and corridors into the secondary rooms on the inside. The office exhaust air is passed on for heating into the sky gardens and centrally exhausted from there. Apart from air conditioning, the underfloor units also take over the temperature regulation function in the offices. The basic load of heating and cooling is guaranteed by the concrete core activation used, while the variable portion is furnished by the underfloor panel devices.
Cooling is done in both cases with groundwater. The workspaces in the outer offices are individually supplied with fresh air in this way, since the underfloor units are separately adjustable for each office for air conditioning, heating and cooling. In the building phase, only every second axis was equipped with active underfloor unit equipment. The remaining axes are equipped with a dummy panel, so that it would be simple to install equipment at a later date.
