What Is a DTS Section J, JV3 Assessment?

JV3 is the alternative assessment method for non-residential buildings which uses a reference building to compare the overall assumed energy consumption of new buildings with respect to their location and climate. There are a number of reasons why a JV3 alternative assessment should be part of your new design. In our world there are no identical buildings when we assess energy consumption. A building with the exact same design, layout, and building materials, can have a different energy use than its twin that may be xx kilometres away. Due to factors like its location and specific weather conditions the annual energy consumption can be significantly different.

When is a JV3 Assessment required?

JV3 can be used as an alternative solution when a section J report is required. This applies when a building’s complex design does not meet the Deemed to Satisfy (DtS) requirements under the National Construction Code (NCC).  JV3 allows much more flexibility with regards to design choices, as architects and designers can create as they see fit as long as it does not exceed the reference buildings energy usage targets. JV3 is much like a non-residential equivalent of NatHERS modelling, allowing flexibility to choose glazing and building elements as long as it stays within the annual energy consumption of the Deemed-to-Satisfy (DtS) building.

The JV3 Assessment requires a detailed assessment of the building’s design. The feedback that is given from the JV3 model should be a consideration in the detailed design’s development.

DtS Solutions

A DtS Solution requires at least one of the Assessment Methods under the NCC to be used. These include an Evidence of Suitability and Expert Judgement.

Example of the JV3 Verification Assessment Method

Below is a step-by-step outline of conducting an analysis to determine whether the Performance Solution satisfies the Performance Requirement.

Step 1 – DtS provisions are used to establish the base performance

JV3 Building Classes

JV3 applies to all buildings of Class 3, 5, 6, 7, 8, and 9 and is not application to buildings of Class 2 and 4. The energy used by services in a Performance Solution are related to the energy used the services used in a DtS Solution.

What Is a DTS Section J, JV3 Assessment?

JV3 is the alternative assessment method for non-residential buildings which uses a reference building to compare the overall assumed energy consumption of new buildings with respect to their location and climate. There are a number of reasons why a JV3 alternative assessment should be part of your new design. In our world there are no identical buildings when we assess energy consumption. A building with the exact same design, layout, and building materials, can have a different energy use than its twin that may be xx kilometres away. Due to factors like its location and specific weather conditions the annual energy consumption can be significantly different.

JV3 is generally more expensive than Deemed to Satisfy (DtS) Section J compliance as it takes much more time to assess. This process involves the comparison of a proposed design with a DtS reference building whilst also taking into account the specific location and weather data of the proposed building. The proposed building must not exceed the annual energy consumption of the DtS reference building, this allowing much more flexibility when design, with building elements being able to be chosen as long as the sum of the whole building does not exceed the maximum annual consumption. JV3 is much like a non-residential equivalent of NatHERS modelling allowing flexibility to choose glazing and building elements as long as it stays within the annual energy consumption of the DTS building

 

What are the requirements of a JV3 report?

A JV3 assessment requires an accurate 3D model of the proposed building with the correct location, orientation and climate information imputed into the software. Lighting, occupancy and external heat loads are also required to assess the overall operational usage of the building, which is then assessed for every hour throughout the year and compared against a reference building.

The JV3 Verification Method uses a thermal model of the building’s design. There are three main facets involved in the JV3 process, these being the inputs, outputs and calculations:

Inputs

  • The design documentation of the Development Application (DA) that is used to conduct the preliminary assessment.

Outputs

  • The preliminary DtS assessment of Section J
  • The preliminary JV3 Report
  • Feedback with the client and the designers
  • The final JV3 Report

Calculations

  • Reference building model
  • Proposed building model
  • Simulation of the thermal model
  • Revise the model after analysis results

How is JV3 Assessed?

This process involves the comparison of a proposed design with a Deemed-to-Satisfy (DtS) reference building whilst also taking into account the specific location and weather data of the proposed building. The proposed building must not exceed the annual energy consumption of the DtS building, this allowing much more flexibility when designing, with building elements being able to be chosen as long as the sum of the whole building does not exceed the maximum annual consumption. The JV3 alternative assessment can be used to attain certain flexibility when designing, such as glazed elements (e.g. the amount, orientation and quality), the building fabric (e.g. the envelope, facades, floors, walls, and roof) and when planning the services (e.g. air conditioning, lighting and heating) as opposed to just a DtS Section J report.

JV3 Verification Method

The proposed building’s annual energy consumption is not to be greater than the annual energy consumption allowance.

The subject building’s annual energy consumption is assessed in:

  • MJ/m² per annum or
  • kWh/m² per annum

The energy consumption is compared with a reference building’s theoretical annual energy consumption. The reference building assumes that it complies with the Deemed-to-Satisfy (DtS) requirements.

Steps in using the JV3 Verification Method

  1. Determine the consumption of annual energy allowance by using a reference building with DtS provisions to model the criteria in JV3.
  2. Calculate the theoretical amount of annual energy consumption of the proposed Performance Solution through the building criteria of the subject or the criteria in Specification JV.
  3. Calculate the theoretical amount of annual energy consumption of the proposed Performance Solution by modelling the services with that of the reference building.
  4. Compare the output of steps 2 and 3 (theoretical annual energy consumption) to the output of step 1 (annual energy consumption allowance). This ensures that the annual energy consumption is not greater than the allowance

    JV3 Building Classes

    JV3 applies to all buildings of Class 3, 5, 6, 7, 8, and 9 and is not application to buildings of Class 2 and 4. The energy used by services in a Performance Solution are related to the energy used the services used in a DtS Solution.

How much does a JV3 assessment cost?

This is generally more expensive than DTS (deemed to satisfy) section J compliance as it takes much more time to assess, and much like the section J report the price is project based and varies greatly depending on size and complexity, therefore to get a quote on a JV3 report for your project click the button below for an obligation free quote or call us and we can discuss your options.Request A Quote
