BRANZ Guideline August 2011 NZS 4218 2009 Calculation Method Tool on the BRANZ website

Issue 31 – September 2011

The NZS 4218:2009 Calculation Method Tool contained within the Toolbox on the BRANZ website now has a 'Building Elements' page that allows individual window and door sizes to be entered into the program. Once entered, they are automatically shown in the project summary sheet. This allows the user to keep track of windows entered and makes evaluation of changes made to the window and door design easier. Note that the widths and heights will need to be entered in mm, for example, enter '2000' for a 2 metre dimension.
