Step 2: Pre-Qualify

This energy self-assessment calculator is designed to first estimate your current energy costs for different equipment and operations and then estimate the potential energy and cost savings if high efficiency equipment was used. This will help you determine economical energy savings opportunities for your dairy farm. This assessment tool will calculate the potential energy savings for scroll refrigeration compressors, refrigeration heat recovery, well-water cooled precoolers (heat exchangers), variable-speed milk pumps, variable-speed vacuum pumps, and high-efficiency ventilation fans.

Indicate which technologies you currently use so the calculator can pre-screen your situation to see if a more in-depth analysis is warranted.

Click on the pictures of the different technologies below to get a brief description of the technology and some of the important operating parameters and maintenance issues.
