The direct energy savings from efficient lighting can be as high as 90% (although is usually closer to around 50%). However, there are further indirect savings which can be achieved - these are outlined below...

Breakdown of the savings possible...


The DIRECT energy cost savings...				A GREEN BUSINESS LIGHT CASE STUDY The proposal - Green Business Light was approached by the site manager of a large cold store warehouse. On the site were 140 metal halide low bay lights which were switched on 24 hours a day, 7 days a week. What we did - Green Business Light was able to propose a sophisticated LED low bay lighting system. This system was projected to give a 75% DIRECT energy saving (including the control system), and the INDIRECT maintenance costs would be reduced significantly, with maintenance expenses being eliminated. The outcome - After installation, the LED lighting system was shown to be responsible for TOTAL energy savings of around £1600 per month.
In large buildings, a general rule is that older metal halide or HPS lights can be replaced with energy efficient fixtures that will reduce energy consumption by approximately 50% - the precise level of direct energy savings will depend on: How ineffective is the current lighting system? - i.e. is there presently very poor light positioning/directioning - this may allow a very low power, high performance fixture to be installed, giving equivalent lux levels in required areas Can an intelligent lighting control system be used? - Using a daylight or presence linked dimming/switching system will further lower the energy consumption of new efficient lighting fixtures. These are particularly suitable in building locations occupied intermittently (e.g. - the aisles of a warehouse). Do lighting levels (lux) need to be improved? - As part of a building upgrade, lighting levels may have to be increased to the recommended guidelines for the work carried out (e.g. - visual inspection). This may reduce the potential energy savings that could be achieved. ff The INDIRECT cost savings... There are also several indirect savings which will result in a much quicker return on investment for any energy efficient lighting project - these are shown below: Lighting system maintenance - the cost of changing expired lamps at high heights can be expensive. If a business does not readily have access to specialist lifting equipment then external contractors need to be paid to do the job. Some long-life energy saving lighting solutions can eliminate this expense completely, with lamp lifetimes up to 100000 hours. Reduced building heat loads - older lighting contributes significantly to building heat loads, with a lot of thermal energy emitted by lamps. This can be costly in large climatically controlled areas, (such as refrigerated storage). Some new solutions use lamps which operate "cool". The climate change levy - the CCL is a direct tax on the energy use of a business. There will be a reduction in CCL payments which is directly related to the energy saved by any new energy efficient lighting system. Enhanced Capital Allowances - an investment in approved energy efficient lighting equipment allows a write-off of the total investment against tax in the first year.
