The BCA Section J Alternative, JV3 Assessment Explained In Detail

The BCA Section J Alternative, JV3 Assessment Explained In Detail

The Inter-Government Agreement(IGA) that focuses mainly on reducing the reliance on regulation, taking into consideration the non-regulatory alternatives like handbooks and protocols that are produced by ABCB.

One such handbook covers all the government concerns related to the building environment.

JV3 is a part of a guide that suggests a ​BCA section J alternative ​assessment method for non-residential buildings. Such buildings use a reference building and compare the overall energy consumption of the prospect building considering the location and the climate. Many builders find it challenging to comply with​ ​JV3 Modeling​.

We have brought down some of the key points required for JV3 assessment. It should include the following:

● It should cover all the details related to the ABCB protocol-compliant software used. ● Ensure the calculation comply with the JV 3 assessment condition and the reference building that is used is also in accordance with the JV3 standards. ● The assessment needs to be carried out only by a qualified and responsible person. The details, including the person’s name, should also be included. ● It is necessary to have quality assurance and an improved system in place.

JV3 Thermal Simulations Condition requirements: ● A 3-D model of the building with an exact location, orientation and the weather. ● The expected and schedules of occupancy, internal heat loads, lighting and the HVAC system should also be included. ● An estimated value of heat transfer and energy consumption. ● Thermostat set at 18 to 26 degrees. ● The AC and the heating Annual ​Energy efficiency ​ration should comply with NCC performance requirement JP3. ● The fresh air rate is 10L/sec/person, and the infiltration rate is 1.0 air changes/hour for the perimeter while the HVAC is operating. ● Your report should specify which components comply and which do not comply with the DTS. The R-value of the compression needs to be calculated. This can turn out to be tricky, and you will need an expert for calculating this.

During the verification method of JV 3 assessment, it is not necessary that all the elements comply with the DTS. If your energy consumption value for the proposed building is less than that of reference building, you can still achieve a compliable building solution.

JV3 modelling ​is more costly and consumes more time than Deemed to Satisfy Section J compliance. With JV3, you have the flexibility of choosing glazing and building elements by complying the annual consumption standard of DTS.

Which building classes are covered under JV3?

All the buildings of classes 3,5,6,7,8, and 9.
