Ventilation is necessary in buildings to remove ‘stale’ air and replace it with ‘fresh’ air:
*Helping to moderate internal temperatures.
*Replenishing oxygen.
*Reducing the accumulation of moisture, odours, bacteria, dust, carbon dioxide, smoke and other contaminants that can build up during occupied periods.
*Creating air movement which improves the comfort of occupants.

Ventilation in buildings can be either natural or mechanical. Mechanical ventilation tends to be driven by fans, whereas natural ventilation is driven by ‘natural’ pressure differences between one part of the building and another.

In modern buildings, which tend to be virtually sealed from the outside, naturally ventilated buildings can suffer problems such as condensation can occur when windows or other ventilators are open, for example in the winter or at night.

As a result, ‘trickle ventilation’ may be provided to ensure there is always an adequate level of background ventilation. Trickle ventilators are typically these are manually controlled slots incorporated into window frames. They generally operated by opening or closing a flap depending on the need for ventilation, however they are intended to be left in the open position.

Trickle ventilators can be self-balancing, with the size of the open area changing automtcially depending on the air pressure difference across it, reducing the risk of draught during windy weather.

It recommended that they are located approximately 1.7 m above the floor

level to avoid creating cold draughts.

‘Crack’ settings (or night latch positions) that allow windows to be slightly open are not generally recommended as a means of providing background ventilation because of the risk of creating draughts and because of security risks.

The requirements for ventilation in the UK are set out in the Buildings Regulations Part F, Ventilation.
