Ventilation components for roofs, façades and lift shafts (SHEV) Lift shaft ventilation Lift shaft ventilation The BlueKit solution Your benefits Chimney effect in the lift shaft A question about safety but also about energy costs An external opening inserted in the shaft head is used to ventilate the lift shaft. This opening is a requirement at European level by virtue of EN 81-20.
However, if this opening is permanently open, this causes considerable energy losses. In winter, heated building air escapes through the non-airtight lift doors and in summer, hot external air which has been drawn in has to be cooled. Without a suitable solution to prevent these losses, energy costs rise significantly.
