The maintenance factor required for determining initial illuminance which describes the installation’s operating behaviour must be agreed upon by designer and operator of the lighting installation according to EN 12464-1. Where this is not possible, the following reference maintenance factors are to be used for planning:
These values assume a higher degree of cleanliness and soiling prevention in healthcare rooms compared to most other work places. This excludes rooms, e.g. for domestic engineering uses, where a higher degree of soiling may be the case.
The numerical requirements for lighting are summarised in table to table.
According to EN 12464-1, the wall surfaces (primary surfaces) in hospitals must be illuminated with at least 75 lx maintained illuminance and the ceiling must feature a maintained value of at least 50 lx (uniformity at least 0,10 for both).
