Colour of lighting and surfaces plays a
very important part in the appearance, operation and ambience
of a space. The most commonly used light sources are
classified according to their colour temperature, measured in
Kelvin (K). A tungsten bulb has a low correlated

• Walls (below 3m) should be uniform, medium
tones to contrast with white balls and shuttlecocks.
- Greens and blues have been successful
colours, with warmer colours becoming popular.
- The recommended wall colour for badminton
halls has been cornflower blue, BS 20E51, which gives a
pleasant appearance whilst allowing good distinction between
the shuttlecock and wall colour.
- Mortar joints should be designed so that
the edges do not catch the light and cause distraction.
• Walls (above 3m) should be lighter, to aid
light distribution.
- Pure white is good for lighting but can
cause problems for viewing small white playing objects.
• Floors should
be of a colour which gives contrast to walls. Light coloured
timber floors (beech) with a matt varnish are recommended.
• Ceilings should be of an unbroken
light colour with a reflectance value which ensures minimum
contrast with sources of illumination in order to reduce glare.
White ceilings are least likely to cause complaints.
- Ceilings are often the worst aspects of a
design, often featuring dark purlins, corrugated surfaces and
little or no uplighting.
• All surfaces should be devoid of any specular reflections,
where the image of a window or light source can be discerned.
- White has been found to be the best
background colour and it is recommended that all structural
elements, including purlins, are painted to match the soffit.
Reveals
The glare from a window can be minimised by
the use of light coloured frames and a light coloured adjacent
wall.
Uniformity
The uniformity ratio gives an indication of
the variation in light levels throughout a room. Uniformity is
the minimum illuminance divided by the average illuminance in a
space. It applies equally to daylight and artificial light.
|
Complete uniformity creates a bland
appearance, whereas excessive variation can be distracting and
have a risk of glare. Sports halls require a relatively high
uniformity to allow fast moving players and objects to be
tracked with ease across the whole floor area.
