Technical Analysis
August 4, 2008
LBNL has provided technical support to the DOE 2008 effort to revise the Energy STAR windows requirements. Our work focused on two main areas:
Updating the modeling assumptions for RESFEN in order to generate space heating and cooling energy impacts from windows in typical new and existing houses throughout the United States:
- "RESFEN6 Modeling Assumptions for the 2008 Energy Star Window Analysis [PDF]
- DOE-2 results of Typical New and Existing One and Two Story Homes:
New Construction
Existing Construction
- Regression Expressions for DOE-2 results [XLS]
Taking RESFEN results for individual houses and developing national energy savings estimates for proposed revisions:
- "A National Energy Savings Model of US Window Sales" [PDF]
- Output Data from the LBNL National Energy Savings Model of US Window Sales [XLS]
(Note: This is a Microsoft Excel spreadsheet — when Excel asks if you want to "Update links to other data sources" click on the "No" button — otherwise, you will have to click through several error messages before the spreadsheet will open).
