How is JV3 different from DTS Section J compliance?

The DTS pathway follows prescriptive Section J requirements for elements such as glazing, building fabric and services. JV3 uses performance-based energy modelling to assess the proposed design against a reference building, which may provide more flexibility for complex commercial projects.

When might a commercial project need a JV3 assessment?

JV3 may be relevant where a commercial project has significant glazing, complex façade design, unusual orientation, design flexibility requirements or difficulty meeting the prescriptive DTS Section J provisions. It can also be useful when the project team is unsure which Section J pathway is appropriate.

What documents are useful for a JV3 project review?

Useful documents may include architectural plans, elevations, sections, project address, building type, approximate floor area, current design or approval stage, and any available glazing, façade, lighting or mechanical information.

Does a JV3 assessment guarantee approval?

No. A JV3 assessment does not guarantee approval. It provides a performance-based compliance pathway using energy modelling and documentation that may support the Section J compliance process, subject to the project details, regulatory requirements and relevant approval authority.

Can JV3 support design flexibility?

Yes. JV3 may support design flexibility where a commercial building design does not easily align with prescriptive DTS requirements. This can be relevant for projects with large areas of glazing, complex façades, orientation constraints or specific architectural design objectives.

How do I start a JV3 assessment with Certified Energy?

You can start by sending your available project documents for review. Certified Energy can assess the information provided and advise whether JV3, DTS or another Section J pathway is likely to be the most suitable next step.

Section J Performance Pathway

JV3 Assessment Support for Commercial Projects

Q: What is a JV3 assessment?

A JV3 assessment is a performance-based pathway used for commercial Section J compliance under the National Construction Code. It uses energy modelling to compare the proposed building design against a reference building to help demonstrate whether the project can meet the required energy performance standard.

Q: Can Certified Energy confirm whether my project needs JV3?

Certified Energy can review available project documents and help clarify whether a JV3 assessment, DTS pathway or broader Section J performance solution is likely to apply. The appropriate pathway depends on the building type, project stage, design details and available documentation.

Q: Is JV3 only for large commercial buildings?

JV3 is commonly used for commercial and complex building projects, but its suitability depends on the project requirements rather than size alone. A document review can help determine whether JV3 is appropriate for the specific building and Section J compliance pathway.

JV3 is a performance-based pathway for commercial Section J compliance, using energy modelling to compare a proposed building against a reference building.

For commercial, mixed-use and complex Section J projects requiring pathway clarity before modelling or reporting.

Certified Energy can review your available project documents and help clarify whether JV3, DTS or another Section J pathway may apply.

JV3 Project Review

Not sure whether JV3 or DTS applies to your project?

You do not need to know whether your project requires JV3 before requesting a review. Certified Energy can assess your project stage, building type and available documentation, then advise whether a JV3 assessment, DTS pathway or broader Section J performance solution is likely to be required.

JV3 may be relevant when a project involves:

Significant glazing

Complex façade design

DTS compliance constraints

Commercial design flexibility

An uncertain Section J pathway

Early design-stage compliance review

For many commercial projects, architectural drawings, elevations, sections and basic project details are enough for our team to understand the scope and identify the next step.

Useful documents to send

Architectural plans
Elevations and sections
Project address and building type
Approximate floor area
Current design or approval stage
Any available glazing, façade, lighting or mechanical information

Send Project Documents for Review

Upload what you have. We’ll review the likely pathway before confirming scope.

You do not need to know whether JV3, DTS or another performance solution applies before sending the project through.

Plans, elevations and sections are usually enough for an initial review. If more information is needed, our team will let you know.

Commercial Compliance Support

Practical Section J pathway support for commercial project teams

Certified Energy supports architects, builders, developers and commercial project teams with early pathway clarification, NCC Section J compliance review, JV3 assessment inputs and coordination of the documentation needed for performance-based energy modelling.

Section J Pathways

Review support where DTS, JV3 or another performance solution pathway may need to be considered.

Project Documents

Available drawings, schedules and project information can be reviewed before confirming the likely assessment scope.

Modelling Coordination

JV3 assessments may require coordination around glazing, façade design, building fabric and proposed services inputs.

Design Team Clarity

Clear pathway advice helps project teams understand whether prescriptive compliance or modelling is likely to be appropriate.

Commercial Performance Pathway

JV3 support for Section J performance solutions

JV3 is commonly used when a commercial project requires a performance-based approach to NCC Section J compliance. Instead of following a purely prescriptive pathway, a JV3 assessment uses energy modelling to compare the proposed design against a reference building.

For architects

JV3 can help support design intent where glazing, façade response, orientation or building fabric require a more flexible Section J pathway.

For builders and developers

A clear JV3 review can help identify compliance requirements, documentation needs and likely project-stage actions before delays arise.

For project teams

Certified Energy can coordinate JV3 assessment requirements across drawings, glazing information, façade design and commercial energy modelling inputs.

Project Review Process

From available documents to a clear JV3 pathway

A JV3 assessment does not always begin with complete documentation. Many projects start with a practical review of the available drawings, schedules and project details so the likely Section J pathway can be confirmed before further modelling or reporting begins.

Step 01

Send available documents

Upload the drawings, schedules and supporting information currently available for the project.

Step 02

We review the pathway

Our team reviews the project type, design stage, building class, documentation and likely Section J requirements.

Step 03

We identify what is needed

If JV3 appears suitable, we clarify what additional information may be required for modelling and reporting.

Step 04

Assessment proceeds

Once the required inputs are available, the JV3 modelling and assessment process can proceed in line with project needs.

Section J Pathways

How Section J, DTS and JV3 relate

Section J sets out energy efficiency requirements for commercial buildings under the National Construction Code. Many projects follow a Deemed-to-Satisfy pathway, often referred to as DTS.

JV3 is a performance solution pathway within Section J. Instead of relying only on prescriptive requirements, JV3 uses modelling to compare the proposed building with a reference building.

For standard prescriptive compliance support, view our Section J report service.

DTS pathway

A prescriptive compliance method where the design must meet set requirements for building fabric, glazing, insulation and other relevant Section J provisions.

JV3 pathway

A modelling-based performance solution where the proposed building is assessed against a reference building to demonstrate an acceptable energy performance outcome.

Why this matters

Choosing the right pathway early can help reduce redesign, clarify documentation needs and support better coordination between architecture, compliance and building performance.

Design Team Support

JV3 support that understands architectural coordination

JV3 assessments often sit at the intersection of compliance, modelling and architectural intent. The assessment may be influenced by façade design, glazing areas, shading, orientation, material selections, insulation levels and commercial building use.

Supporting design flexibility

For commercial projects, JV3 can become especially relevant when the design needs flexibility. This may include projects with large areas of glazing, complex façades, mixed-use zones, shading considerations, or performance expectations that need to be resolved through modelling rather than a purely prescriptive pathway.

Helping the project move forward

Certified Energy helps project teams understand what information is needed, where the compliance pathway may sit, and how JV3 requirements relate to architectural documentation, façade design and commercial energy modelling inputs.

Façade and glazing review

JV3 may help assess how glazing, orientation and façade design affect the building’s Section J performance pathway.

Building fabric response

The assessment can consider how the proposed envelope contributes to the overall commercial energy performance outcome.

Performance pathway clarity

Where DTS requirements create constraints, JV3 may provide a performance-based route for demonstrating compliance.

Earlier Clarity

Why early JV3 review can help

Early review can help project teams understand whether JV3 is likely to be required before documentation becomes too fixed.

This is particularly useful when the project includes significant glazing, façade complexity, unusual orientation, design flexibility requirements or uncertainty around Section J compliance.

Reduce pathway uncertainty

Understand whether DTS, JV3 or another performance solution pathway may be suitable before the project moves too far ahead.

Support design decisions

Identify performance considerations before façade, glazing or building fabric decisions are fully locked in.

Improve documentation readiness

Clarify which drawings, schedules and project inputs are likely to be needed for JV3 modelling and reporting.

Avoid late-stage redesign pressure

Earlier pathway review can help reduce compliance surprises when documentation, procurement or approvals are already underway.

Pathway Clarification

Not sure whether your project needs JV3?

Not every commercial project requires a JV3 assessment. Some projects can follow a standard DTS pathway, while others may need a performance solution because of glazing, façade design, building fabric, orientation or broader Section J compliance requirements.

If you are unsure, that is a normal starting point. Certified Energy can review your available documents and help clarify the likely compliance pathway before the project moves further into documentation, pricing or approval.

Send your available drawings and we can review whether JV3, DTS or another Section J pathway may apply.

Common Questions

JV3 Assessment FAQs

These questions help explain how JV3 assessments relate to Section J compliance, DTS pathways and commercial building performance requirements.

What is a JV3 assessment?

A JV3 assessment is a performance-based method used to demonstrate compliance with NCC Section J energy efficiency requirements for commercial buildings. It uses energy modelling to compare a proposed building with a reference building.

Is JV3 part of Section J?

Yes. JV3 is a performance solution pathway within the broader Section J compliance framework. It is often used when a commercial project needs modelling-based assessment rather than a strictly prescriptive pathway.

How is JV3 different from DTS?

DTS, or Deemed-to-Satisfy, follows set prescriptive requirements. JV3 uses performance modelling to show that the proposed design performs at least as well as a reference building.

When is JV3 required?

JV3 may be required or recommended when a commercial project cannot easily meet standard DTS requirements, or when a performance solution is needed to support the proposed design.

Can JV3 support façade or glazing flexibility?

Yes. JV3 can sometimes support greater façade or glazing flexibility by assessing the building through a performance modelling pathway rather than relying only on prescriptive requirements.

What documents are needed for a JV3 assessment?

Typical documentation may include architectural drawings, elevations, sections, glazing schedules, façade details, insulation information, mechanical assumptions and relevant NCC or Section J documentation.

Can you review early-stage drawings?

Yes. Early-stage drawings can often be reviewed to help identify whether JV3 may be relevant and what information may be needed before modelling or reporting begins.

Is JV3 only for large commercial buildings?

JV3 is generally associated with commercial and non-residential building projects, but suitability depends on the project type, building classification, design and compliance pathway.
