• Changing Rooms

The difficulties presented for the ventilation of changing rooms centre around the body odours and stale air generated as a result of the occupants activities. Ventilation equipment should be mounted to the opposite end of the entrance door of the changing room, and sited at a high level.

Changing room doors are normally fire rated, therefore shut- so it is advisable to make provision for draught free replacement air.

Effective ventilation is now a primary consideration in the design and construction of all buildings.

Where changing rooms are located adjacent to shower rooms, the levels of condensation created from the shower facilities can be a problem for occupants in the changing area. However, this is alleviated when the precise ventilation is selected for the rooms, by taking into consideration the large volumes of air required to extract the steam generated from hot showers, particularly where there are a number of showers on at any one time.

Equally, when designing the ventilation system, it is important not to create too much airflow, as an excessive amount of air that moves across naked bodies in shower rooms can make showering less comfortable for the individual.
The level of humidity generated in this environment can be quite significant, so it is good practice to extract from these areas, as the humidity levels will eventually damage the decor and soft furnishings. Odour will also be a problem in changing rooms.

The type of fan selected shall depend on whether the application is for domestic (shower rooms) or commercial (changing rooms and shower areas).

Most bathrooms will be fitted with a through-the-wall extractor but a shower enclosure, or a shower in a confined space e.g. basement will require an in-line extractor which can extract the moist air over a longer distance.

Whenever a shower is installed it is always advisable to fit an extractor fan to remove excessive water vapour and condensation. This is especially important in rooms where there are no windows or en-suites where the moisture-laden air may cause discomfort If not removed.

The extractor fan can be turned on via a pull cord, which must be beyond the reach of anyone using the shower, a humidistat which automatically turns on when needed or a switch connected to the lights. The latter is usually used in rooms with no windows and is a building regulation requirement.

They include the assessment of correct extraction rates, the power and correct placement of the extractor, establishing the source of return air, taking into account energy saving issues and the correct choice of dueling through which air must flow efficiently.
