VURB vs DTS: Residential Compliance Pathways

By Team CE on May 30, 2026 9:33:10 AM

 

Residential Compliance Pathways

Residential energy compliance is not always resolved through one universal pathway. Some dwellings can follow the Deemed to Satisfy provisions directly. Others may justify investigation of a Performance Solution supported by a compliant reference building comparison.

Verification Using a Reference Building, commonly known as VURB, provides a defined comparative method where it is available under the applicable NCC and jurisdictional provisions. The question is not whether VURB is better than DTS. The question is which pathway is legally available, technically appropriate and proportionate for the dwelling being assessed.

Home Energy Rating: Australia’s Next Residential Performance Shift

By Team CE on May 29, 2026 3:22:49 PM

 

Quick answer

 

Home Energy Rating is the emerging consumer-facing pathway for understanding the energy performance of existing Australian homes.

 

It supports the expansion of NatHERS into existing homes and may help homeowners, assessors, property professionals and policymakers make better-informed decisions about comfort, energy use, upgrades and future disclosure at sale or lease.

NatHERS Existing Homes: why practical assessment delivery matters

By Team CE on May 27, 2026 11:51:27 AM

NatHERS Existing Homes is more than a new assessment category. It represents a wider shift in how Australia understands the energy performance of homes that have already been built, occupied, renovated, altered and lived in over time.

Documents Needed for a Section J Report

By Team CE on May 26, 2026 12:17:13 PM

For most commercial building projects, the first step is a practical review of the available drawings, schedules and design information. These documents help the assessor understand the building classification, envelope, glazing, construction systems and relevant building services.

The documentation does not always need to be final before an initial review begins. It does, however, need to be clear enough to identify the building, the proposed work and the likely energy-efficiency compliance pathway.

The more useful question is therefore:

Which documents are needed now, and which details must be confirmed before the Section J Report can be finalised?

Design Optimisation and BASIX in NSW | Certified Energy

By Team CE on May 25, 2026 8:00:15 PM

NSW Residential Compliance Guide

BASIX design optimisation is the process of identifying which project inputs are limiting compliance and refining them without making unnecessary changes to the wider residential design.

 

A project that does not initially achieve its required BASIX outcome does not necessarily need a complete redesign. In many cases, the result can be improved through a targeted review of the assumptions, specifications or design elements affecting the relevant assessment component.

The important first step is diagnosis. Water, energy and thermal comfort respond to different inputs, and a change that improves one part of the assessment may have little effect on another. Repeatedly upgrading unrelated products can increase project cost without resolving the actual constraint.

This guide focuses specifically on how BASIX outcomes can be refined through a structured design process. For the wider assessment, certification and NSW submission pathway, visit the BASIX Knowledge Hub.
