Milk Chilling Energy Efficiency Calculator

To start calculating your energy savings, you’ll need to have your Energy Efficiency Checklist handy.

If you haven’t filled out a checklist yet, start by printing out the Energy Efficiency Checklist.pdf. Once you’ve filled in all the relevant details from your dairy shed, pop back to this site and enter the details into the calculator.

Completed your checklist already? Then you’re ready to transfer your details into the calculator. We’ve entered some default numbers to guide you, so all you need to do is replace these with your own accurate information and the calculator will do the rest for you.

Don’t forget to save! When you’re finished, click ‘save information’ and you’ll be able to review your information at any time.
