Can I Save Money on Building a High-Performance Home?Key Insights on Energy Efficiency and Cost Savings
Can You Really Save Money with a High-Performance Home? (Yes, You Can)
We get this question all the time: “Aren’t energy-efficient homes more expensive to build?” It’s a fair concern, and we totally understand where it comes from. But let’s clear something up.
Yes, building a high-performance home does involve some upfront planning and smart choices. But when you look at the full picture, the numbers actually swing in your favour, both now and over time.
At Zelena Homes, we’ve helped families across Geelong, Torquay and the Surf Coast create homes that are not only beautifully comfortable but also budget-smart.
Here’s what you need to know.
The Myth: “Energy Efficiency Costs More”
It’s easy to assume energy-efficient homes are only for people with big budgets. But in reality, the things that make a home high-performance, like airtightness, good insulation and smart design, are not luxury extras. They’re the foundations of a better build.
And when you don't build with performance in mind, you could be setting yourself up for higher energy bills, more repairs, and even future renovations.
The Reality: Smart Design = Real Savings
Here’s how a high-performance home helps you save, during the build and for years to come.
1. Lower Energy Bills from Day One
This is the big one. Because your home stays warm in winter and cool in summer, you don’t need to blast the heater or air con.
What helps?
North-facing windows that let in winter sun
Airtight construction that stops draughts
Continuous insulation that keeps temps steady
HRV systems that keep the air fresh without wasting energy
Our clients often tell us their new energy bills are a fraction of what they used to pay.
2. Smaller Heating and Cooling Systems
Less energy loss means you don’t need massive systems. Smaller split systems or fewer units can mean lower upfront costs.
3. Fewer Repairs and Less Maintenance
A drier, well-insulated home doesn’t struggle with mould or condensation. That means fewer headaches and fewer repair bills.
4. Higher Resale Value
Buyers are getting smart. Homes that are cheaper to run and more comfortable year-round tend to sell faster and for more.
5. Possible Rebates and Incentives
From solar panels to all-electric heating, you might be eligible for government rebates. We help you explore those options when they’re available.
More Comfort, Less Cost
One Surf Coast family we worked with was worried about going over budget. But by focusing on smart orientation, solid insulation, and skipping oversized gadgets, they ended up with a home that’s cheaper to run than their old rental.
Their words?
“We didn’t have to choose between comfort and affordability. We got both.”
