EXECUTIVE SUMMARY
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.
