Energy Efficiency for Buyers: How to Tell if a Home Will Be Warm (or if You’ll Need Upgrades).

September 27, 2025

Canberra winters are chilly — and if you’re buying a home, energy efficiency should be near the top of your checklist. A property that’s poorly insulated or drafty can cost you thousands in heating bills and make your home uncomfortable.


Here’s how to spot whether a home will stay warm in winter (and cool in summer), plus what upgrades you might need after purchase.

Why Energy Efficiency Matters in Canberra

  • Comfort: Canberra’s climate has extreme cold winters and hot summers. Good insulation and glazing make a noticeable difference.
  • Costs: Heating and cooling are among the biggest household energy expenses.
  • Resale value: Buyers are increasingly prioritising energy-efficient homes — making upgrades a smart investment.

Key Features to Look For When House Hunting

1. Insulation Levels

Check whether the ceiling and walls are insulated. Insulation is often hidden, but the seller or agent should be able to confirm.

  • R4.0 or higher for ceilings is recommended in Canberra’s climate zone (per YourHome).
  • Poor or missing insulation = higher bills and colder winters.

2. Windows and Glazing

Single-glazed windows lose up to 40% of a home’s heating energy.

3. Draught Proofing

Check for gaps around windows, doors, and floorboards. Even small draughts add up.

  • Simple upgrades (seals, draft stoppers) can save hundreds annually.

4. Orientation and Sunlight

Homes that face north (with living areas on that side) get better winter sun. Shading or verandas help reduce summer heat.

5. Heating and Cooling Systems

Efficient systems like reverse-cycle air conditioning or hydronic heating are ideal. Old gas heaters may be expensive to run and less efficient.

When Upgrades Are Worth It

If the home you love isn’t energy efficient, don’t panic — upgrades can transform it.

  • Install ceiling and wall insulation → $3,000–$7,000 depending on size.
  • Upgrade to double glazing → A significant upfront investment, but long-term energy and comfort savings.
  • Seal draughts and gaps → Often under $500.
  • Add external shading/awnings → Keeps summer bills lower.

FAQs

Ask the seller or check the building report. Ceiling access points sometimes allow you to see insulation.


Is double glazing worth it in Canberra?

Yes. It reduces heat loss in winter, keeps homes cooler in summer, and adds resale value.


What’s the cheapest upgrade for energy efficiency?

Draught sealing and heavy curtains are low-cost ways to improve comfort quickly.
