Section J Solution

The performance solution allows to offset the losses in glazing with better performing components. It also allows to trade off between the components of the building fabric. We have plenty of experience in providing performance solutions-JV3.

Call us to find out how we can help you achieve the compliance solutions.

JV3 Assessment

All new builds are required to be energy efficient. This is made mandatory through the ABCB code that specifies certain minimum level of efficiency. For commercial buildings the energy efficiency provisions of Section J can be achieved through ‘Deemed to Satisfy’ method or alternative method known as JV3 method.

The Alternative solution/performance solution allows to offset the losses in glazing with other better performing building components. It also allows to trade-off between the components of the building fabric.

JV3 assessment in Australia is conducted by “Section J consultant in Australia”. The modelling is based on idealized building usage prescribed in ABCB building code.

The intention is to design and build efficient building fabric as it outlives the mechanical and electrical services.

We conduct JV3 modelling on computer software designed to suite to Australian weather data. The modeling software IES <VE>is certified to be used on ‘Commercial energy modelling Australia’.


Why verification Method ?
Verification method (JV3) is to demonstrate that a Performance solution meets the requirements. JV3 provides flexibility where the prescriptive DTS provisions may not work or may not be desirable method of achieving Section J compliance.

How does JV3 achieve Compliance ?
JV3 assesses the annual Greenhouse gas emissions (GHG) of the proposed building and compares it with the annual GHG of reference building (a building which would achieve compliance through DTS provisions). The overall GHG emissions of the Proposed building need to be lower than the reference buildings.

What are the benefits of JV3 Method ?
JV3 method allows for trade-offs’ between various components of the building fabric, such as high level of insulations on ceiling with lower than stipulated insulation on walls. This method allows flexibility in the design of wall-glazing construction (amount, quality, orientation and shading), insulation and sealing of the envelope (walls, floors and roof) and configuration of services (air-conditioning, lighting, lifts and electrical services).
