• Sports Centres

There are a variety of activities that take place in any sports centre, with the air changes per hour variant depending upon the activity.

One of the primary considerations is the need to remove excessive body heat and odours, ensuring a constant supply of fresh air, maintaining a comfortable environment, particularly in summer time conditions, whilst preventing condensation and ensuring where spectators are present, they are kept cool.

Clearly, ventilation designs should be intended to provide controlled ventilation rates so as to vary in relation to the occupants needs at any given time, without bringing in large volumes of colder air into the area, which may cause discomfort and high heating loads.

Badminton for example, requires a draught free playing area, which is necessary to prevent deflection of the shuttlecock.

It is recommended that design temperatures should be between 16 to 19°C, which is established as the comfort zone for playing the game. It is also recommended that no less than 1.5 air changes per hour should take place. Furthermore, any ventilation system that moves the air can deflect the shuttlecock; therefore it is important that ventilation systems are designed to account for this.

The location and protection of all air input and extraction grilles or openings must be carefully considered particularly in relation to the flight path of the shuttlecock.

It is better if ventilation systems are designed to operate around the perimeter of the sports hall to limit air movement over the court. The air velocities within the playing area should not exceed 0.1 metres per second.

Fitness suites and weight training facilities, because of the metabolic heat gains, the need for effective ventilation is the most critical factor since body odours and humidity can rapidly occur in these areas. It is important to note that special considerations may need to be taken into consideration for spas, saunas and solaria.

Squash courts need to be well ventilated, as the walls must be free from the build up of condensation, whilst removing player's body heat generated. The incoming air should not be drawn from bar areas, showers, changing rooms or other parts of the building with high humidity levels. As a general rule, each court would have an extract fan centrally placed at high level, whilst the fresh air can be drawn in through airbricks behind the play board. It is recommended the fan should overrun for 15 minutes after the courts have been vacated to ensure that all stale air has been removed. In addition, the rate of ventilation in the spectator gallery may have to be based on maximum occupancy levels.

Ancillary halls are used for a variety of sporting and social activities, including public entertainment. Consequently, the range of potential activities would need to be confirmed with the client prior to finalising the design of the ventilation system. A wide range of air change rates may be required, for e.g. the removal of odours to ventilate the area for discos and dances.

Changing rooms in larger buildings will require a mechanical supply and extract system. In small facilities, satisfactory conditions may be achieved with conventional radiators and convectors combined with natural ventilation or local extract fans. The high fresh air requirement allows for heat recovery to be cost effective.

Elta Fans provide a wide range of ventilation products for the diverse applications that may exist in a sports hall. Whilst some examples have been provided, there are many more, so for more information, please look at examples of typical products that could be used for sports hall applications, or alternatively, please contact us to discuss your specific application requirement.
