BCA Section J Assessment Methods

There are two methods to determine compliance of a building under BCA Section J: Deemed-to-Satisfy (DTS) and Verification using a reference building (JV3). DTS is the most common and straight forward method, and is suitable for most buildings. It involves a desktop review of the building plans to verify compliance with relevant provisions of the BCA Section J. The second method, JV3 requires advanced thermal modelling and is primarily used when compliance via DTS is not possible or where substantial construction cost savings can be made. Generally DTS is the preferred method, as it is usually the most straight forward and less labour intensive to conduct. JV3 is most commonly used for designs where compliance under DTS is not possible, or where there is the potential for construction cost savings.
