BCA Section J Compliance – DTS, JV2 and JV3 Modelling
The Building Code of Australia – Section J is a national set of technical provisions relating to buildings energy efficiency that must be met as the minimum standard for all buildings. There are a number of methods to achieve these standards depending on the type of building, climate zone and process used to obtain compliance.
BEAC offers all three methods of obtaining compliance as follows;
- DTS (Deemed to Satisfy) – The building design is checked for compliance against a number of set requirements. If compliance is not met, notice will be provided to the developer to amend the design.
- JV2 (Verification Method 2) – This method is currently being phased out across Australia. It involves modelling the energy use of the proposed building, with the proposed services and ensuring this is not above a specified value for that location. A second model is then produced of the proposed building, with the minimum standard services. This also must be under a specified value of energy consumption.
- JV3 (Verification Method 3) – This involves modelling the building with proposed fabric and proposed services and comparing this to a reference building. The building fabric is then modelled with the reference building services and again this is compared to the same reference building. In both comparisons the proposed building must use less energy than the reference building.
