Hotel customers switch on lighting automatically.
.
When a car enters the car park at the Grand Hotel Excelsior in Malta, the lights switch on automatically at the floor level where they park. It wasn’t always so.
The car park is built into the side of a hill and has two levels used by customers. The lighting was permanently switched on and the installed load was costing just under €12,000 per year (at 2010 prices).
A short energy survey carried out by CTC Energy included a proposal to install lighting controls which were fitted early in 2011. The result was startling. The lighting full load is now never on for more than a maximum of two hours per day realising savings of around €10,000 per year - all this for the cost of PIR’s and controllers totalling €360 making a payback of only 12 days! This represents a saving of over 80%.
Pedestrians entering the car park of any one of the two foot entrances per level also switch on the lights automatically for a pre-set period allowing plenty of time to enter cars on leaving the premises.
A hidden benefit of this installation is maintenance. Much lower use of the lighting means that lamp failures are greatly reduced. Additionally, the sensors may be integrated into the security system such that any activity in the car park “out of hours” is detected immediately by the security department.
Similarly a public car park in Southampton installed lighting controls which realised savings of 53%.
The question now is: do your customers automatically control YOUR car park lighting yet?
