Energy Efficiency Glazing Calculator

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.
