Installation Notes:

      Some Anti-Virus software may interfere with Reference Ace installation. Discuss the implications of temporarily disabling the software with your IT representative.

      If you install the Reference Ace locally, it will not run in Chrome or Opera.  It does display in those browsers in the online version (on the Energy Code Ace web site).



Use the Reference Ace carefully. Topics in the Standards and Manuals are hyperlinked, but the links are not comprehensive. There may be additional information in other topics that are not shown in the links. Use caution when searching the documents to ensure you have all relevant information.


The Reference Ace helps you navigate the Standards and related documentation more easily, including the following features:

Ø HYPERLINKS:  Jump to a referenced section with a single click.

Ø POP-UPS:  Click on key terms to display the definition.

Ø SEARCH:  Search for a word or phrase and all topics containing that term appear in a list.  If you select the option, the term is highlighted within each topic.

Ø FAVORITES:  Because the Reference Ace runs in your internet browser, you may use the browser's "Favorites" feature to bookmark your commonly-used topics.


CURRENT RELEASE: Version 3.1 of the Reference Ace includes the 2016 Building Standards reference documents (2016 'Building Energy Efficiency Standards, 'Reference Appendices, Residential and Nonresidential Compliance Manuals, and Residential and Nonresidential Alternative Calculation Method (ACM) Reference 'Manuals).
