Foreword:
 

Good design needs to be based on a sound
understanding of such issues as the current trends
and practices within individual sports, the wider
leisure industry and the lessons to be learnt from
previously built schemes.

Good design needs to be embraced within the
earliest vision statement for a particular project
and enshrined in the initial briefing stage through
to the final detailed specifications and operational arrangements.

Court dimensions:

1 Badminton court dimensions showing the 6.1 x 13.4 m court and the minimum run-off areas.
2 Three dimensional representation of the playing
area, consisting of the Badminton court and the required
clear height zone above it. Also illustrated is the layout
of chairs for match officials.

Table 2 Minimum spaces around courts:

3.0 Space between courts
Table 2 shows the minimum run off requirements
around a court at different levels of play. The
same minimum space should still be maintained
between all courts whatever the size of the hall.
The distances from court lines to division curtains
must be allowed on both sides of the curtain if
there are Badminton courts on both sides.

Where appropriate, additional space should be
allowed for spectators and players to sit, for
circulation, and for match officials’ seats and
judges’ tables, especially where the facility is to be
used for tournaments.

If the hall dimensions are larger than necessary,
then the spaces around courts can be greater.

Spaces larger than the minimum recommended
safety run-off dimensions are generally acceptable.

However, if the hall dimensions are less than
standard, then the spaces between courts and
between courts and walls will be less than the
minimum recommended to provide a safe run-off.
In these circumstances the operator should
undertake a risk assessment and must provide
alternative control measures to ensure safety.

Where this is not practicable, it may be necessary
to reduce the proposed number of courts, or it
indicates that the hall may not be suitable for
playing Badminton. Courts with less than the
recommended minimum space around them are
not approved by BADMINTON England.

Where this is not practicable, it may be necessary
to reduce the proposed number of courts, or it
indicates that the hall may not be suitable for
playing Badminton. Courts with less than the
recommended minimum space around them are
not approved by BADMINTON England.

Layout of Courts:
 
The court must be marked out in easily
distinguishable 40 mm wide lines. They may be
applied by paint or inlaid and should be matt white
in colour. In exceptional circumstances, where it is
not possible for these lines to be white, yellow may
be an acceptable alternative. Where a
multi-purpose hall is accredited / funded by
BADMINTON England, the badminton lines should
be dominant.
Where the courts are laid out “end to end” there
must be a curtain between the ends of the courts
and it is essential that the minimum run-off
dimension is maintained on both sides of the
curtain (see Table 2). In this configuration, to avoid
any distractions caused by movement and lights
from the other courts, the curtain between the
courts should preferably be of solid material to full
height, rather than standard sports hall dividing
nets.
 
Flooring:
 
The preferred flooring for playing badminton is a
sprung floor covered with a vinyl impact absorbent
covering. This creates an area-elastic floor covered
with a point-elastic top layer; and is referred to as
a floor with combined-elastic properties.

The other type of floor commonly used and
accepted by BADMINTON England is a sprung
floor covered with wooden strip flooring to give
area-elastic properties. The top surface should be
laid as parallel strips rather than herringbone or
other patterns which can be distracting to players.

Some facilities for multi-sports use, particularly on
school sites, are fitted with a seamless wet-poured
polyurethane flooring system. This would normally
create a point-elastic floor but, if a synthetic
area-stiffening component is introduced to create
a mixed-elastic floor, this may be acceptable for
Badminton.

The standards and testing methods for sports
floors are covered by British/European Standard
BS EN 14904:2006: Surfaces for Sports Areas -
Indoor Surfaces for Multi-Sport Use. See also
Sport England Design Guidance Note ‘Floors for
Indoor Sports’.
The finish to the flooring should be matt to avoid
any glare. Preferred colours are green, blue or
natural timber with a transparent seal.

Where a facility does not offer the right flooring
specification and layout for Badminton, a portable
court mat may be placed over a sprung surface to
provide the right playing conditions. This is
commonly done for major one-off competitions.
However, the size and weight of these mats can make laying, lifting and storing them a problem. It
is also important to consider the interaction
between the existing and portable floors to ensure
that the combination is stable and meets the same
performance standards as a properly specified
permanent floor would deliver.

In older existing halls solid floors are often used i.e.
concrete, screed or composition flooring. This is
NOT acceptable for the playing of Badminton and
injuries can be caused with this type of floor. This
type of floor can be improved by covering the
existing hard floor with laminated timber planks on
rubber strips, or with a foam-backed cushioned
sheet material.
 
walls:
 
A background against which a fast moving shuttle
can be seen easily is critically important for the
successful playing of the game.
The ideal badminton hall has four plain walls with no
windows or roof lights. There should be no distracting
attachments, particularly brightly coloured items.

There should be no ledges or other projections likely
to trap shuttles. The surface texture, colour and
reflectance value must be consistent and
uninterrupted over the full height of the hall. In the
case of a refurbishment where it is not practical to
remove glazing, it must be covered by blinds or
shutters to exclude natural light completely.

Acoustics:
 
The internal acoustics of a hall can have a
significant impact on its suitability for Badminton,
and particularly for coaching the sport. Badminton
does not require the walls to be as robust as some
other sports necessitate. However, multi-sport
halls need hard surfaces, to withstand impact
damage, and these tend to have poor sound
absorbency properties, which results in sound
reverberating within the hall. This can lead to poor
speech intelligibility and high background noise
levels, making it difficult for coaches to manage
and control their players For Badminton halls, the overall construction
should be designed to provide sound absorption
qualities with a reverberation time of 1.5 - 2.0
seconds at mid-frequency. This can be achieved
by integrating suitably robust sound absorbent
materials into the ceiling and/or upper wall levels
e.g. acoustic blocks or acoustic wall panels.

However, it is important for Badminton that there
are no visual distractions, so any acoustic materials
introduced must blend with the surrounding walls
in terms of texture and colour.

The level of sound insulation in the building should
be sufficient to prevent players being distracted
by external noise. A standard noise rating of 40NR
would normally be specified. Heating and
ventilation equipment should be as quiet as
possible in operation.

Ceilings:
 
The ceilings in sports halls are often the underlining
to the roof, which is usually of a sandwich
construction. The underlining can be of an acoustic
material and, as with the walls, this is very
important to the environment of the hall. In many
cases a self-finished acoustic lining with a light
colour is ideal for the ceiling and complies with the
required reflectance values of 70–90 %.
 
Lighting:
 
Lighting is one of the most important requirements
in the design of a hall where badminton is to be
played. It is essential to consider lighting early in
the design stage so that the lighting layout, lamp
type and background colours can be co-ordinated
with other aspects of the design. (ref. Sport
England’s forthcoming Design Guidance Note
‘Artificial Sports Lighting’).

The lighting design in a badminton hall must take
into consideration the requirements for provision of:
• A safe environment for players
• Effective illumination of the shuttlecock and
court markings to aid players and to assist
match officials in the execution of their duties
• Suitable and sufficient lighting for spectators.
When designing the lighting for badminton halls it
is important to appreciate how the game is played.
The shuttle can move at very fast speeds over the
net, requiring maximum light reflecting from the
white feathers of the shuttle.

The shuttle can best be seen when illuminated in
this way against a dark background, therefore the
rear of the court does not need to be lit to such a
high level as the centre.
 
Heating and ventilation:

Most sports hall heating and ventilation systems
will be designed to deliver a temperature range of
12 - 20oC. The most comfortable temperature for
playing Badminton is around 16oC. Temperatures
as low as 12oC may be acceptable, particularly for
performance play and it is recognised that, without
air cooling, temperatures may exceed 20oC during
periods of hot weather but, wherever possible,
heat loss/solar gain should be minimised through
insulation.

It is recommended that no less than 1.5 air changes
per hour be made. Any heating or ventilating system
that moves the air can deflect the shuttlecock;
therefore it is important that heating and ventilation
systems are designed taking this into account. 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
hall, to limit air movement over the court. The air
velocities within the playing area should not exceed
0.1 m/s (metres per second).

Where air velocity cannot reasonably be limited to
0.1 m/s, the ventilation system should be fitted with
an override switch or ‘Badminton Button’ in an
accessible location, to disable the system when the
hall is used for Badminton.

The heating system most commonly used in halls
where badminton is played is high-level radiant
panels or tubes fitted to the walls or ceiling, in
conjunction with a controlled ventilation system.
Traditional low pressure hot water radiator
systems, or under floor heating, could be used if
appropriate to the type of flooring. Heating by
warm air is not recommended as it is difficult to
control the air movement when the heating is
operating. Radiant heaters should be fitted with
fine mesh guards to prevent shuttlecock damage.
 
Disability badminton:

The design of any new sports facility should take
account of the needs of disabled people. This is
referred to as ‘inclusive design’. Part M of the
Building Regulations and BS 8300 set out basic
access standards for buildings, but they do not
cover all of the issues which are important in the
design of inclusive sports facilities. Aspects of
design which have particular relevance to disabled
people include layout and signage, the use of
colour, light levels and control of glare, changes in
level, gradients and surface finishes 3.

Disability badminton encompasses various forms
of the sports where the rules of the parent game are
modified to suit the particular disabilities of the
people playing 4. For example, the area in front of
the short service line can be regarded as out of
bounds for wheelchair players and some lower limb
amputee singles players might play singles on half
a standard badminton court, using the centre line
and the doubles sideline as their sidelines.
Wheelchair players also play with the net lowered
by 150 mm. Most court surfaces are suitable,
 
Spectator seating:

viewing area for spectators, waiting players and
team officials is essential. Seats may also be
required in the stands for sponsors and other VIPs,
referees and other tournament officials, and radio
and television commentators. Where possible
competition players should have a separately
marked area for seating when watching matches.
Teams and officials should have a different access
point to spectators Very careful thought should be given to the design
of spectator galleries, since they can sometimes
create difficulties and distractions when viewed
from the court. These areas need to be of similar
colour to the court walls and the lighting should be
subdued and carefully hidden when viewed from
the court. Windows and doors at the rear of the
spectator galleries should be curtained or
designed so that no light can be seen from the
court. If the spectator areas are glazed then
specialist advice should be obtained.
