Energy savings are now becoming the major quick source of cost savings in these times of austerity and cutbacks. Sometimes the ideas are such that they can inhibit the work levels that need to be attained but savings in electrical usage can at times be made without any loss in commercial or production activity.
Taking a typical office activity the lighting bill is about 39% of the total energy usage and sometimes it is possible to reduce this significantly. If it is also combined with an automatic shading system then the savings can often multiply. Lutron claim that they were able to save the New York Times some $600,000 per annum from the introduction of a total light and shading automated control system.
