• CUAC Equipment Stock Accounting: Revisions to ensure that 

equipment stock under the base case equals equipment stock 

under the standards cases

- Revision drops National Energy Savings approximately 10%.

• Building Efficiency Trend: Results provided previously did not 

account for a more efficient building stock over time. Efficiency 

trend implemented from Annual Energy Outlook.

- Revision drops National Energy Savings approximately 10%.
