The ABCB has developed a suite of glazing calculators to assist NCC users with the calculations required by the energy efficiency Deemed-to-Satisfy Provisions. Once users have entered the necessary data into the spreadsheet, which operates in Microsoft Excel, all table references and calculations are carried out automatically.
The glazing calculators for use with NCC 2014 Volume One and Two have been updated. Minor editorial changes have been made to both calculators. The Volume One calculator has been updated to align with the NCC 2014 changes in glazing energy index options for Class 9c buildings. These calculators are compatible with Excel 2007 or later for Windows or Excel for Mac 2011 and are available for download at the bottom of this page.
Additional glazing calculators for use with previous versions of the NCC are available on the archived documents tab.
The ABCB has also developed an information booklet called Energy Efficiency Glazing Provisions for BCA Volume Two – Changes Introduced in BCA 2010 and Advanced Glazing Calculator Techniques. It is designed to assist users with the Glazing Calculator for NCC Volume Two and is available for download here.
Energy Efficiency Glazing Provisions for BCA Volume Two (2010)

The information is organised in the following sections: glazing basics, changes in calculation methodology for climate zone maps 2 to 8, changes to the glazing calculator layout, advanced glazing calculator techniques, glazing in alterations and additions.
The glazing calculators have been developed by the ABCB to assist in developing a better understanding of glazing efficiency parameters. While the ABCB believes that the glazing calculators, if used correctly, will produce accurate results, they are provided "as is" and without any representation or warranty of any kind, including that they are fit for any purpose or of merchantable quality, or function as intended or at all. Your use of the glazing calculator is entirely at your own risk and the ABCB accepts no liability of any kind.
