I've been reviewing some lighting calculations that have been undertaken for a scheme we're on to which the designer has left the 0.5m boundary on every space. For narrow corridors this practically leaves nothing left to measure on the calculation and seems a bit of a cheat to achieve a higher lighting level. I'll accept it in large open spaces but in areas such as WC's and corridors i'm reluctant too. Hes quotes clause 2.1.3.4 out of the SLL code of lighting 2012 but reading this again i think this relates more to office areas.

Can someone tell me is there a clause somewhere that identifies for these types of spaces you need to calculate the full space? I know on the emergency side you need to but in regards to general lighting.

The corridor in question is 1500mm wide so by adding this 0.5m boundary you are only calculating a 1/3 of the space.
