Energy use in a brewery extends well beyond generating steam and heating water. The total annual electric bill for a 10,000 barrel-per-year brewery could often vary between $40,000 and $55,000, contributing to a significant portion of a brewery's operating costs. One utility expense that often receives minimal attention but can have a major sustainability impact is lighting. For many breweries, upgrading the lighting system can save 30% to 40% off the current consumption for lighting. The Appleton™ Industrial Mercmaster™ Connect LED Luminaires with Plantweb Insight™ Connected Lighting Application is an excellent solution to reduce lighting costs while allowing a brewery to use lighting more economically by monitoring modes of operation.
