Agriculture and Food Processing

Growers, dairies, packers, and other food and beverage producers all runs operations that can benefit from the latest energy management best practices. To keep their costs down, savvy operators use rate analyses, pump tests and process optimization audits to identify their best options,  Audit recommendations often include re-scheduling operations to take advantage of a demand response program or a time-of-use rate, and making hardware improvements like installing advanced irrigation equipment, high efficacy lighting, or premium efficiency motors and HVAC equipment (e.g., variable speed drives, plate coolers, compressor heat recovery units, scroll compressors, time clocks, ventilation controls) and more.

    Design Brief: Demand Response

    Demand response (DR) is an energy management strategy that allows electricity consumers to receive financial compensation for temporarily reducing or rescheduling power use upon request. DR creates opportunities for building owners and managers to realize financial, operational, and environmental benefits by changing energy use patterns in response to market signals.

    e-News #74: Combined Heat and Power

    A building may contain a vast array of efficiency measures, or it may be old and inefficient. Either way, the electricity used in the building will likely be produced with inherent inefficiencies. The efficiency of fossil fuel based electricity production averages 34% (although new combined cycle plants can exceed 50% efficiency). The ultimate efficiency of any building pulling electricity from the grid is limited by that number.

    e-News #71: Evaporative Cooling: Saving Energy in More Ways Than Ever

    Evaporative coolers provide cool air by forcing hot dry air over a wetted pad. The water in the pad evaporates, removing heat from the air while adding moisture. Although the concept has been used in residential "swamp" coolers in the Southwest for decades, technology advances have made evaporative cooling a viable alternative to conventional cooling in commercial buildings and in other areas of the country.

    The kitchen ventilation system is one of the largest energy-consuming end uses of a commercial food service facility. In a typical restaurant, the HVAC (heating, ventilation and air conditioning) system represents 20 to 30 percent of total energy consumption. The kitchen ventilation system can account for up to 50 percent of that HVAC load.
