Energy-efficient homes are better for the environment and better for your hip pocket. By including energy efficient features in your new home, you can significantly reduce running costs, improve the quality of your home and ensure it is more comfortable to live in year-round. By choosing to build all-electric with solar PV, you can take control of your energy consumption and protect yourself from the rising cost of energy in the home.
Annual energy and utility bill savings of 2023 Good Friday Appeal Charity House when compared to the same home if it were mixed fuel. This assessment was conducted using Sustainability Victoria’s Whole-of-Home Pilot Tool.

Representatives of Henley, Sustainability Victoria and Efficiency Matrix tour the 2023 Henley Good Friday Appeal Charity Home and discuss its energy efficiency features and the benefits of building all-electric.
Aimee: Welcome to Henley's beautiful Electra 35.
It's actually a 36 square home, and it's got four beautiful, spacious bedrooms, five living areas, and a grand alfresco.
It's also part of Sustainability Victoria's 7 Star Homes program.
So Sustainability Victoria, on behalf of the Victorian Government, has been working with Victorian builders to improve the energy efficiency of these beautiful new homes and this is a great example.
Aimee: Yes, yes it is.
This is actually a 7 star home and it produces more energy than it consumes, which makes it a net
zero house, which is fantastic.
Sarah: So the new energy efficiency standards come in in October 2023, and that will mean we move from a minimum of 6 to a minimum of 7 stars for all new homes. And this is a great example of a 7 star home.
Can you tell me a little bit about what makes that possible?
Aimee: Yes. So we were very fortunate. We have great orientation with this block. So we have northern access into the main living areas. We also focus quite heavily on window sizing and location and obviously the use of double glazed windows really helps us out there. We've got insulation all throughout the home, which is fantastic, and we really tried to focus on some thermal mass with our flooring. So we've got tiled flooring to our main living areas, which obviously helps.
Sarah: Yeah, it does. And it also means the home is going to be cooler in summer and warmer in winter, which I think is going to be great for the climate resilience we need for our homes in the future.
Aimee: Yes, it's fantastic.
Sarah: [New] Energy efficiency standards also include the introduction of a whole of home energy use budget, which looks at the appliances in the home, such as heating, cooling and hot water and lighting.
Aimee: Yes, that's correct.
And with the help of the Seven Star Homes Program and Sustainability, Victoria's whole of home pilot tool Henley has actually been able to demonstrate savings of up to 70% with the use of all electric and solar, which is just fantastic.
Sarah: So Mike, the new all electric homes, they tend to be cheaper to heat, cool, and run than traditional gas and electric homes that we look at. So can you tell us a little bit about what the energy savings would be for at this home?
Mike: Certainly, so the new home owners of this rather large house would expect to pay around about $515 per year on their total energy bills. So that represents a saving of around about $1013 per year over this exact same house in dual fuel configuration. We've achieved a lot of that via the ducted heat pump heating and cooling. We have a heat pump hot water system as well, and also we don't have the gas meter coming in, so around about $338 per year on connection or service fees.
Sarah: Fantastic. And all those savings are going to be passed on to the new homeowner
Mike: Every year. Yep.
Sarah: So, John, can you tell us a little bit more about as built verification?
John: Sure, so when we modelling these homes for its energy efficiency capabilities, we assume that all of the walls and the ceilings are completely airtight, but also very well insulated. In fact, perfectly insulated.
So when we actually do our process of ABV for the Sustainability Victoria 7 Star program, we install a blower door and induce a pressure differential for the building envelope, and when we’re inducing that pressure differential, we can feel leaks coming from all the different holes around the building envelope, which contributes to the level of air tightness of the home. And then we also go through and with the temperature differential between inside and outside we can document where there might be insulation missing on the ceilings or the walls, which goes towards a percentage of uncoverage.
Sarah: And that helps those homeowners get that certainty, in the quality of the product that they're
getting at the end of the day.
John: Correct. Because we document exact locations of where these issues are so that the builder can go ahead and remediate those before handover.
Mike: So Sarah, thanks for coming to take a tour of our Henley Electra 35.
Sarah: It's a wonderful home and 7 stars, all electric, too, so thanks so much.
Aimee: No worries, lovely to have you.
