Energy Efficiency for Building Alterations (Australia)

EE-04 Solutions – Compliant Energy Upgrades for Existing Homes

Home Energy Rating offers EE-04 solutions for renovations, extensions, and alterations to Class 1 buildings, ensuring every project is fully compliant with the latest energy regulations in Australia. Our EE-04 service helps homeowners, builders, and designers meet National Construction Code (NCC 2022) energy standards efficiently and cost-effectively.

What Is the EE-04 Solution?

EE-04 is the energy efficiency compliance method for alterations and additions to existing houses in Australia. It sets out how renovations and extensions must meet NCC requirements, focusing on practical performance and reasonable upgrades for thermal comfort, insulation, and energy use.

Energy Efficiency Assessment

Key features:

  • Applies to Class 1 buildings: detached houses, townhouses, and similar dwellings.
  • Covers energy efficiency upgrades for insulation, glazing, building sealing, and services.
  • Uses both NatHERS software assessments and Elemental Provisions for practical compliance.
  • Allows flexibility for extensions, relocated/prefab buildings, and partial compliance when full upgrades aren’t practicable due to technical or cost limits.

EE-04 Solutions Process

  • Consultation & Planning: Review your renovation goals, building docs, and site needs.
  • Assessment: ChooseNatHERS rating or Elemental Provisions as best suited to the upgrade.
  • Report & Recommendations: Receive a compliance report outlining mandatory and recommended energy upgrades.
  • Certification: All upgrades documented and certified—ready for council, building surveyors, and easy permit approvals.
Who Needs EE-04 Solutions?
  • Renovators: Anyone altering an existing home structure, adding new rooms, or extending floor area.
  • Builders & Designers: Professionals responsible for meeting NCC energy efficiency rules during upgrades.
  • Owner-builders & Homeowners: Those seeking cost-effective ways to improve comfort and lower bills while staying fully compliant.
What’s Included in an EE-04 Assessment?
  • NatHERS Assessment: If using NatHERS rating software, alterations/extensions can be rated for thermal performance, showing how upgrades improve efficiency.
  • Elemental Provisions Compliance: For parts of the building not suited for NatHERS modelling, compliant upgrades to insulation, windows, sealing, and heating/cooling systems are recommended.
  • Partial Compliance Guidance: The surveyor can grant “partial compliance” for hard-to-upgrade sections (per Regulation 233), ensuring the most practical and reasonable improvements are made.
Typical upgrade options include
  • Floor insulation: Especially in living areas above underfloor heaters/ducts.
  • Double glazing: Low-emissivity glass with argon fill for enhanced thermal resistance.
  • Air sealing and draught proofing: Reduces heat loss and discomfort.
  • Appliance upgrades: More efficient heating/cooling, water heating, and lighting systems.
Why Choose EE-04 Solutions?
  • Compliance: Meet current NCC 2022 rules without unnecessary expense.
  • Customised: Solutions tailored for your home’s age, design, and local climate.
  • Energy Savings: Modern insulation, glazing, and air sealing upgrades can drastically lower bills.
  • Future-proofing: Get ready for stricter energy codes and improve property value.
