Energy-efficient green warehousing

1 05 2011

Due to rising energy costs and legal requirements warehouses have to be designed and operated in an energy efficient way in order to meet new requirements and remain competitive.

However, on this subject just a few best practice cases are known. Therefore, it seems likely that the energy-efficient storage, the “Green Warehousing”, isn’t really noticed by all the industry and there are a lot of areas to improve.

Therefore let’s have a look on the following video which presents the methods and tools for increasing energy efficiency in warehouses:

Different types of renewable energies are used in order to realize energy-efficient warehouses as you have seen. For example energy-efficient green warehouses are equipped with solar panels on their vast roofs to generate electricity. Furthermore the facilities could be equipped with underground geothermal energy systems in order to provide a very effective cost saving renewable energy for such large buildings.

Moreover a green warehouse should be equipped with plenty of windows to provide natural lighting in order to save electricity. If there is no daylight available common lightning should be replaced with energy efficient lightning like LED’S for example.

An example for a high efficient lightning in warehouses is WOW Logistics, an Appleton-based warehousing company. The company replaced all of its high-pressure sodium lighting and mercury vapor lighting with 6,000 fluorescent lighting fixtures in all of its public-owned distribution centers.

The lights are also set on five-minute timers and equipped with photo sensors. This ensures that when a part of the warehouse is in use, it’s lit up appropriately for employees. On the flipside, for those areas not in use, energy is not wasted.

The energy savings resulting from the project is significant: In each distribution center, the new fixtures decrease air pollution and environmental damage by 43 pounds of carbon dioxide, 722,779 grams of sulfur dioxide and 1,676,848 grams of nitrogen oxide each year.

As a result the warehouse can save up to 70-80% on energy bills like shown in the video:
