EER Rating vs Home Energy Assessment in Canberra
EER rating vs home energy assessment in Canberra: which one do you need?
Short answer: An EER (Energy Efficiency Rating) is a standardised star rating, often required when selling or leasing a home in the ACT — it’s a compliance document. A home energy assessment is a deeper, practical inspection that shows where your home loses energy and how to fix it — it’s for owners who want to lower bills and improve comfort. If you’re listing a property, you need an EER. If you want to actually improve your home, you want an assessment.
What is an EER rating?
An Energy Efficiency Rating (EER) scores a home’s energy performance on a star scale. In the ACT, an EER is commonly needed for mandatory disclosure when a home is sold or rented. It’s a standardised, comparable figure — useful for buyers and tenants, and a legal box to tick for sellers and landlords.
What an EER is good for:
- Meeting ACT sale/lease disclosure requirements
- Giving buyers a quick, comparable performance number
- A fast, baseline snapshot
What it is not: a detailed roadmap for improving your home.
What is a home energy assessment?
A home energy assessment is a hands-on evaluation of how your home actually uses and loses energy. Using blower-door testing, thermal imaging and a whole-of-home review, an assessor finds the air leaks, insulation gaps, glazing weaknesses and heating/cooling inefficiencies that drive up your bills — then gives you a prioritised plan to fix them.
What an assessment is good for:
- Cutting heating and cooling bills
- Improving year-round comfort
- Planning renovations or retrofits
- Deciding which upgrades to fund (e.g. via the ACT Sustainable Household Scheme)
- Building toward Passivhaus-level performance
EER vs assessment: side by side
| EER rating | Home energy assessment | |
|---|---|---|
| Purpose | Compliance / disclosure | Improvement / savings |
| Typical trigger | Selling or leasing a home | Wanting lower bills & more comfort |
| Output | A star rating | A prioritised action plan |
| Depth | Standardised snapshot | Detailed, home-specific |
| Best for | Sellers, landlords, agents | Owner-occupiers, renovators |
Which one do you need?
- Selling or renting out a property in the ACT? You likely need an EER for disclosure.
- Staying in your home and want it warmer and cheaper to run? You want a home energy assessment.
- Planning to use the Sustainable Household Scheme? Start with an assessment so you fund the right upgrades.
- Building or deeply renovating? A Passivhaus-informed assessment guides the whole project.
Some Canberra homeowners get both: an EER for compliance, and an assessment to actually improve the home.
Why a Passivhaus-trained assessor matters
Passivhaus is the international gold standard for low-energy, comfortable buildings. A Passivhaus-trained assessor doesn’t just measure your home — they understand how air-tightness, insulation, glazing and ventilation work together, so the plan you get reflects best-practice building science, not guesswork. In Canberra’s climate of cold winters and hot summers, that difference shows up directly in your comfort and your bills.
