Cost of Ownership Modelling
Cost of ownership modelling illustrates the total and true cost of owning and running your lighting, which goes way beyond just the cost of the lamps. The report is compiled using your real, actual data and includes lamp costs, power consumption, your Kw/hr charge, hours of usage and maintenance costs.
We examine lighting in every area of your installation including car parks, reception areas, offices, stairwells and corridors. In any one installation a multitude of different lamp types may be used in different zones, often incorporating old and inefficient technology, from low voltage and mains voltage halogen to T8 fluorescent tubes, SON and metal halide.
Our team will identify a far more energy efficient retrofit solution in each case, offering a lower energy use and a greatly improved lamp life. We call this “uplamping”. Payback periods are often very short when following the recommendations within our Cost of Ownership report. Take the example of a hotel replacing 300 x 50w 2000 hour Halogen lamps with 300 x 35w 4000 hour Infra Red Coated halogen lamps. In this example the hotel can expect to save £1427.79 in one year, based on a daily usage of 10 hours, with a Kw charge of 10p per hour.
In other cases cost savings may be made not just through using a more efficient lamp but one of longer life. Take the real example of the business park in south London which was using 2000 hour lamps in its emergency fittings. These fittings, which had to be operational by law, are situated five stories up on the outside of the office buildings and require qualified rope access technicians with cherry pickers when a lamp needed changing. The client estimated that the cost of changing each lamp was over £300 ...The case for using 15,000 hour lamps was somewhat easy to sell!
