Food for thought
During this two-part webinar series, take a birds-eye view at energy use in food manufacturing facilities then dive deep into how to manage air infiltration.

Part one: Food processing—energy savings potential

As a result of part one of this webinar series, you will be able to:

  • Identify the primary uses of electricity and natural gas in a typical food manufacturing facility.
  • Discuss the energy efficiency opportunities in 9 different types of food manufacturing facilities.
  • Explain energy efficiency best practices for 15 different categories of food manufacturing equipment and systems.
  • Describe non-energy savings benefits of energy efficiency projects.

Part two: Food processing—energy efficient refrigeration

As a result of part one of this webinar series, you will be able to:

  • Explain why air infiltrates through doorways of industrial refrigeration storage spaces and suggest ways to reduce air infiltration.
  • Discuss factors that contribute to latent and sensible loads in industrial refrigeration storage spaces.
  • Describe ways to improve defrost cycles and reduce energy use.
  • Discuss evaporator defrost cycle options.

Who should watch?
Facility operators and maintenance personnel, contractors, system operators, design engineers and equipment vendors; production staff; industrial refrigeration technicians; and anyone with basic knowledge and interest in industrial food processing energy efficiency best practices.

Part one: Food processing—energy savings potential

We reveal data and share the information you need to evaluate your facility’s energy use in comparison to national energy benchmarks. We share the top energy saving findings from more than 110 food manufacturing facility energy audits and discuss how to incorporate non-energy saving benefits into your sales pitch to upper management in order to get projects implemented.


  • Top 10 average energy users

  • Opportunities and savings potential (example projects)

  • Make the case for project selection

Part two: Food processing—energy efficient refrigeration

We show how minimizing air infiltration through doorways in industrial refrigeration storage spaces reduces sensible and latent loads, cutting costs during the cooling and defrost cycles. Learn the driving forces behind air infiltration, as well as how to reduce it. We examine strip curtains and air curtains, and discuss how to calculate flow rates and energy savings. In addition, we show you how to evaluate defrost frequency and dwell time through careful observation and monitoring—a crucial step not to be missed when evaluating energy efficiency at your facility.
