It can be argued that the energy saving needs of an industrial exteriors outweigh that of private exteriors
. When the goal is profit maximisation reducing operations costs whilst maintaining efficiency is key. Solar-powered units with rechargeable batteries allows for such savings and can be especially useful in more remote locations where access to electricity is limited. These types of units can be stand-alone and some can combine solar and wind power to charge the battery units for a very long lifespan. Occupancy and Daylight control are great ways to prevent unnecessary exterior lighting usage and maximise battery reserves.
