Sales and Sales Share

The document describes the application of Sales and Sales Share variables in stock-turnover analyses to model how new energy efficiency or emissions standards for new technologies impact the overall average values of a total stock as older devices are replaced. It outlines two analysis types—Transport Analysis for vehicles and standard Stock Analysis for other devices—and explains that data can be entered via bottom-up technology branches or a top-down approach using shares. It further notes that Sales variables operate from a specified First Sales Year and are paired with Survival Profiles to model device retirement.

• Stock-turnover analysis is used to model the gradual improvement of average values across a total stock of devices as new technologies with updated energy efficiency or emissions standards replace older ones.
• Users can input Stocks and Sales data using either a bottom-up method at technology branches or a top-down approach where total values are entered at top-level branches and distributed via Stock Share and Sales Share variables.
• The Sales variable tracks the addition of new devices starting from the First Sales Year, while a Survival Profile is used to define the rate at which these devices are retired over time.
