Our team was responsible for the implementation in Piasta Towers residential buildings. Starting from design and planning, through implementation and assembly, to final acceptance. The scope of work included: ventilation installation in residential and service premises, common and technical parts, as well as in a multi-storey underground garage. Our task also included the installation of smoke removal for the staircase. In addition, we installed air conditioning systems in some residential and commercial premises.
The magnificent INX Hotel not only offers comfortable rooms, cafes and restaurants, but also a SPA, fitness room and enables the organization of conferences. Our team installed 5 Bartosz ventilation units with complete automation servicing all hotel rooms accordingly. In addition, the installation included the installation of exhaust and supply fans for technical, hygienic and sanitary rooms, as well as communication routes. We were also responsible for the installation of mechanical and gravity ventilation for the boiler room.
Gravitational smoke exhaust systems are most often used in buildings with large cubature, i.e. shopping centers, industrial halls and warehouses as well as staircases in public buildings. Automatic smoke ventilation is used in these facilities. It discharges volatile combustion products, i.e. gases and smoke, outside the building through automatic smoke exhaust devices. Smoke extraction and compensatory air supply are provided by smoke vents and smoke vents and smoke curtains.
Mechanical smoke extraction systems remove smoke using fans. Such smoke exhaust ventilation is located on the roof or in ventilation ducts and is used in multi-storey buildings – where it is not possible to smoke directly from the fire zone through smoke exhaust flaps. Mechanical smoke exhaust systems include smoke extract ducts, fire ventilation flaps and smoke exhaust fans with adequate fire resistance.
Smoke extraction of a building often uses both systems: gravitational and mechanical.
Smoke extraction with exhaust fans requires an aeration system. Aeration is necessary to maintain overpressure relative to adjacent rooms, as it prevents smoke suction in the event of a fire.
Smoke extraction systems protect vertical escape routes, i.e. staircases and fire vestibules. They are also used to remove smoke from extensive fire zones, including garages and escape corridors.
In many facilities, smoke extraction systems are obligatory, e.g. in closed garages with an area of> 1500 m2 (§ 277.4 ), in staircases and fire vestibules in high-rise buildings (§ 246.2 ), in indoor pedestrian routes to which service premises are adjacent (§ 247.2 ).
In some buildings, smoke exhaust systems are necessary because their installation ensures larger areas of fire zones or long escape routes. Smoke ventilation also allows the architect to lower the fire resistance class of an object.
