The Energy Efficient Warehouse Lighting Example

The following example is based on an energy efficient warehouse lighting survey recently undertaken by SolEco. It offers a realistic understanding of potential energy savings that can be made in a typical warehouse when replacing existing lighting with our new range of energy efficient products. As well as warehouse lighting this example can be applied to energy efficient distribution centre lighting installations

This example obviously makes some assumptions based on the feedback taken from the initial onsite warehouse lighting energy survey. They are as follows:

• Cost of electricity: 11p per kWh

• Operational hours of site: 24hours a day, 7 days a week. Total of 8760 hours per annum.

The initial survey also identified other key factors that would assist in reducing lighting energy consumption and achieving a complete energy efficient warehouse lighting installation. These are:

• Although the site is in operation for 24 hours a day, 7 days a week the actual occupancy time within this area is far lower. Therefore, a proposal was put forward to offer presence detection as a trigger to control the lighting system. This allows the warehouse lighting to be switched off during periods of non-occupancy and on when presence is detected.

• Also, the roof was made up of a high proportion of skylights which offer impressive levels of natural daylight. We therefore took light readings in order to ascertain the actual levels of natural daylight. This was then averaged out to balance the differences in daylight hours throughout a year. By integrating daylight linking within the system it is possible to dim the luminaires to a lower level depending on the contribution of natural daylight.

Taking this all into consideration the following warehouse lighting results were found:

The findings show that by replacing with energy efficient warehouse lighting on a one-for-one light fitting basis the savings that can be achieved are very impressive indeed. With a 54% reduction in warehouse lighting energy consumption this equates to a massive £77,316.85 saving per annum offering a short payback period with substantial profit increases thereafter. If you couple this with the added product benefits such as longer lamp life, reduced maintenance costs, better light distribution and improved working conditions the overall package is almost too good to refuse.
