Usually Open-Plan-Space are used quite differently and demand a wide range of different lighting solutions. Ideally, artificial light presents itself in perfect harmony to daylight. Even without daylight the relevant light conditions should be similar to a situation with daylight.
Open-plan spaces such as the dealers' room of a large bank or the visual control room of an airport are characterised on the one hand with the intense use of computer screens, on the other hand with an insufficient amount or complete lack of daylight.
Under these circumstances the following lighting concepts have proved to be suitable: generous direct/indirect lighting offering excellent visual conditions, especially when the direct and indirect components can be independently operated and dimmed.
The use of indirect components, preferably with a neutral to daylight white light creates the impression of daylight. The use of direct components, especially with a warm white light creates the sensation of an evening atmosphere.
Because both components are discharged by large surface luminaires, direct glare as well as reflected glare on workstation surfaces is eliminated. A zonal lighting control is advantageous in order to satisfy the varying lighting needs of different work groups during the daytime as well as at night.
A lighting management system fulfills the needs of regulation according to aspects of place and time.
