NCC: Meeting the Performance Requirements
This video provides an overview of the Assessment Methods contained in the NCC, which are used to demonstrate compliance with the Performance Requirements.

The National Construction Code also known as the NCC contains mandatory Performance Requirements [Book open at page with Text saying: "Performance Requirements" with check box points and set of scales] that set the minimum level [Ticks placed in check boxes] that buildings, building elements and plumbing systems must achieve.
There are three options to satisfy the Performance Requirements – [Text saying: “Deemed-to-Satisfy and/or Performance”] a Deemed-to-Satisfy Solution, a Performance Solution or a combination of both. [Book open at page with icons of four assessment methods] To achieve compliance, one or more of the four assessment methods described in the NCC must be used.
It can also be used as part of a Performance Solution. [Graphic: Open report with Text saying: "Test Report No. 3795"]
Evidence could be a report from a registered testing authority or in the case of Volume Three, from a recognised expert, a definition specific to that volume. [Graphic: Certificates of conformity] Or, it could be a current certificate of conformity or a certificate issued by a product certification body, [Graphic: Certificate of Accreditation and Professional Engineering Certificate] or a certificate of accreditation or a certificate from a professional engineer, [Graphic: Magnifying glass moving over open report with graphs and tables] or any other form of documentary evidence that is acceptable to the appropriate authority. [Circle with Text saying: "And one other thing…"]
And one other thing, plumbing and drainage is different when it comes to evidence of suitability for products and materials. [Graphic: Tap with water coming out] Plumbing materials and products that are covered by the Watermark Certification Scheme have specific evidence requirements. [Circle with Text saying: Watermark (Logo)] They require a current certification mark through the Watermark Certification Scheme.

The second assessment method described in the NCC is a Verification Method. [Graphic: Magnifying glass moving over model of house, experiment flask and Text saying: "a + b = x"] To determine whether a Performance Solution complies with the Performance Requirements, a test, inspection, calculation or other method may be used. While the NCC contains a number of Verification Methods, [Graphic: Book open at page with model of house and drawing of tap with Text saying: "Verification Methods"] a Verification Method that is not from the NCC may be used if the approval authority deems it acceptable for determining compliance with the Performance Requirements. [Circle with Text saying: "Remember…"]
Remember using a Verification Method is an option to meet the Performance Requirements. [Graphic: Book open at page of four icons with flashing icon of documents]The third assessment method enables a designer to compare the performance of a proposed design to the performance produced by relevant Deemed-to-Satisfy Provisions.
[Graphic: Icon of clipboard with bar graph, Symbol “=”, Text “or”, Symbol “>, Icon of clipboard with text “DTS”] When using the comparison method the Performance Solution needs to demonstrate an equivalent or superior performance to the Deemed-to-Satisfy Provision to meet the Performance Requirement. [Graphic: Book open at page of four icons with flashing icon of person wearing hard hat]The fourth assessment method allows the use of expert judgement. It requires than an expert assesses relevant qualifications and sufficient experience to determine the adequacy of a Performance Solution. [Graphic: 3D technical drawing] It is usually applied where a proposed design relates to Performance Requirements that are difficult to quantify.
[Graphic: Book open at page of four icons with icons flashing on a rotation] Remember when meeting the Performance Requirements one or more of the four assessment method options may be used. [Graphic: Icons of clipboards, certificates, reports, design drawing and mathematical formula move into open folder] All decisions made in the process of developing or approving a solution as well as the evidence used to make those decisions should be documented. [Graphic: Tick appears on front of folder]
Tools provided by the ABCB to assist in the development of solutions include [Graphic: Icon of book, Text saying: " Performance Solution Process, Guidance Document"] a guidance document to assist in developing Performance Solutions.
Further details are available in the Governing Requirements of the NCC. [Graphic: Open book with scales, checkboxes and Text saying: " Governing Requirements"]
