The indoor emergency lighting system (2) comprises at least one emergency luminaire (3, 4, 5), an emergency situation determination unit (7) and a controlling device (6). The controlling device (6) controls operation of the at least one emergency luminaire (3, 4, 5), wherein the controlling device (6) is configured to output an emergency situation information signal in response to a determined emergency situation. The outdoor lighting system (30) comprises at least one outdoor luminaire (8 to 13) which is communicatively coupled to the controlling device (6) of the indoor emergency lighting system (2). The energy storage (22, 25) is configured to selectively supply power via power supply wiring to the at least one luminaire (8 to 13) of the outdoor lighting system (30) in response to the emergency situation information signal output by the controlling device (6).
