In New South Wales, Part 3.12 does not apply and is replaced by the New South Wales requirements set out in Annex A.c) Evaluate the results of Step (b) against the acceptance criteria set out in the performance-based design description. The requirements take into account the geological or geographical conditions of the site. In the different climatic conditions in Australia, some areas will be dominated by heat and others by cooling. These requirements are compared to the performance bands that indicate the “number of stars” of this building. (a) develop a performance-based design mandate in consultation with relevant stakeholders. In NT, Part 3.12 is replaced by the requirements of Part 3.12 of BCA 2009. For other states, the local variations contained in Part 3.12 must be taken into account. This method compares the performance of the modeled proposed building with a similar modeled building against the dtS regulations (often referred to as a “reference building”). Performance requirement P2.6.1 sets the standard that a home must achieve in terms of the level of thermal performance of the building envelope (i.e., the fabric of the building). People often refer to the requirements of the Australian Building Code (BCA) as “6 stars”.
However, the 6-star requirement is one of the many ways available to comply with BCA`s energy efficiency requirements. BCA is performance-based code, which means that it allows a number of available paths to meet mandatory performance requirements. These requirements are prescribed in Parts 3.12.1, 3.12.3 and 3.12.4. The PBDB is to be developed in collaboration with key stakeholders as part of the performance-based design and approval process. The objective of the PBDB is to record the core activities and outcomes of the performance-based design process, as agreed upon in negotiations with key stakeholders. In the context of the fire, it is like the Fire Engineering Brief (FEB) process, but with a fundamental change where all relevant stakeholders must understand and accept the content of the FEB before a final report is prepared. This is a significant change from how the FEB was previously agreed and is now a breaking point in the design until an agreement is reached. The overall process is to: (b) conduct an analysis using one or more of the evaluation methods listed in Part A2.2(2), as proposed in the performance-based design document. Note: The above information is only general advice and HIA recommends to builders, planners, etc.
before using a methodology to demonstrate compliance with the CBA`s energy efficiency requirements, discuss this with the energy assessors, building certifiers and relevant regulatory authorities for the project in question to ensure that the requirements of the CBA are met. This method adds the thermal resistance (R-value) of each building element to quantify the performance of the building and compares it to the prescribed minimum values. This means that the floor, wall, roof, windows, etc. of the building must be constructed in such a way that the house naturally maintains a certain level of thermal comfort. Artificial heating and cooling can still be installed, but the design of the building and the materials used must naturally maintain a certain level of thermal comfort, thus reducing the amount of artificial heating and cooling. Ultimately, the BCA`s requirements are aimed at reducing greenhouse gas emissions through the efficient use of construction services. Performance requirement P2.6.2 applies to fixed services installed in the building and refers to their efficiency and power consumption/supply. During this process and to ensure compliance with the NCC, a performance solution must be evaluated using one or more of the evaluation methods described in the NCC. The overall process consists of: Performance solutions have sometimes been controversial because they are perceived as non-transparent in how they meet NCC performance requirements and different documentation standards (if documented). During the analysis process, several studies or design scenarios may have been considered and analyzed.
It is necessary to collect and evaluate the results of the analysis process and draw conclusions to form the final report. .
