    The EXPO 2000, Phase IV Building is a new construction. It is designed as an office building with an underground garage. The building consists of two underground floors occupied by parking lot, technical rooms and storage areas and eight floors above designed for open office spaces. The lifts, restrooms and other service facilities needed for the functionality of the offices are located in the core of the building.

    Heating and Cooling Systems

    Heating – the building supply with hot water for heating is established via two multifunctional air-cooled heat pumps located on the roof. They provide simultaneous both heating and cooling for different building parts. The heating of the building is provided by duct mounted fan coil units and floor heating for the main lobby and by ceiling panels for the office spaces.Air Conditioning -the cold water for the air conditioning of the building is provided by the two air-cooled heat pumps.Via separate heat exchanger the temperature of the cooling agent for the chilled ceiling panels, active chilled beams and fan coil units is raised to 10o/15oC.

    Ventilation systems - the mechanical conditioning ventilation of the building is established via two air handling units with rotary regenerators located on the roof. Part of the air is supplied through active chilled beams located in the suspended ceiling along the perimeter of the building. Secondary treatment of the air from the active chilled beams will be needed if the radiant ceiling cooling fails to meet the cooling load requirements. Exhaust ventilation is partially provided by exhaust grilles located in the upper zone of the premises. The rest of the air is exhausted through toilets and kitchenettes via transfer grilles.

    Separate ventilation systems for fresh air supply for the technical rooms and storages are provided.

    For the garage an exhaust ventilation and smoke extract ventilation via directing jet fans and main ventilator is established.
