3 Course Description Did you know that refrigeration and lighting account for more than 50 percent of total energy use in the average supermarket? During this webinar, we ll identify overall energy conservation opportunities in supermarkets, with a primary focus on refrigeration. Our experts will review energy code requirements for refrigeration and reveal energy conservation market barriers and solutions. Roundy s Supermarkets' energy manager will discuss the barriers he encountered when implementing energy conservation measures, as well as the implementation process. Lastly, since energy modeling is essential to the successful design of an energy-efficient supermarket, we ll explain several modeling tools. Learning Objectives At the end of the this course, participants will be able to: Explain how the latest energy code effects refrigeration design. Describe refrigeration and lighting energy conservation measures that exceed code. Use tools and modeling methods for refrigeration energy conservation measures. Explain energy conservation measure implementation barriers and benefits from the owner s perspective. 3
