2. ECMs for Display Cases

3. 3 Analysis Approach Direct savings calculated as the difference between the baseline input watts and efficient case input watts, multiplied by the hours of annual operation. Input watts are calculated based on industry standard efficiency levels and manufacturer reported output wattages. Weighting is used to account for motors with a range of available output power. Indirect savings are based on typical annual average EER values.

8. 8 Analysis Approach Direct savings calculated as the difference between the baseline input watts and efficient case input watts, multiplied by the hours of annual operation. Baseline input watts are calculated based on test data from door manufacturer. Efficient-case input watts are based on average of test data for products rebated in 2012. Indirect savings are based on typical annual average EER values.
