What is the difference between the National Construction Code facade calculator and Speckel?
The Australian Building Codes Board have made available a downloadable façade spreadsheet at https://www.abcb.gov.au/. Speckel maintains the same calculation methodology as per the National Construction Code 2016 and 2019, where applicable. However, Speckel goes onto provide far more advanced calculations and is not a direct Deemed-to-Satisfy Solution.
Speckel is a Performance Solution (Alternative Solution) that allows building envelope design and construction to directly addresses NCC Performance Requirement. By using calculations and other methods which determine whether a proposed building complies with the relevant Performance Requirements, Speckel may be used if the appropriate authority is satisfied that it establishes compliance with the NCC.
