The 2019 National Construction Code is now in effect; evoking major changes in areas that include fire safety and energy efficiency requirements. Also, quantitative performance requirements are being valued over qualitative performance standards.
The Australian Building Codes Board (ABCB) estimates that nearly half of NCC 2019 performance requirements will be quantified by direct means or via a verification method. To this end, 28 new verification methods have been introduced.
Benefits of these developments will include an increased emphasis on performance requirements in regard to the design and construction of buildings—in terms of safety, resident health and environmental sustainability. On the rise is an increased emphasis on solutions unique to each situation, thus granting leeway to architects and engineers to apply their professional judgment to the cultivation of solutions that will fill performance requirements for each individual situation. This will grant them freedom to innovate; to guarantee the finest feasible methods and materials for specific situations.
Overall, quantified requirements help to guarantee great performance and objective performance levels, with reduced risk for favoritism and misrepresentation. Performance targets could be established in regards to common home components such as air conditioning, minimum required levels of natural lighting, and the required level of sound attenuation of a home in regards to sound transmission.
Innovation and flexibility are the ultimate goals of these numbers-based standards in building construction, which can assign great and literal numerical value to every building design project.
