The Future of the WA Home
Solar, batteries, zoning and smart control are converging into something bigger than any single appliance. Here’s where the WA home is headed
We’ve asked the question that used to have one simple answer, should the air conditioner be running in an empty house, and found that it’s really made up of half a dozen smaller ones: how hot the house actually gets, what the solar system is doing at the time, whether the system can direct its effort somewhere useful, and how much a cooler arrival is actually worth to the household in question.
The direction all of this is heading is fairly clear, even if the details are still catching up. More homes will end up with systems that have some rough sense of the household’s routine, that respond to which rooms are actually in use rather than treating the whole house the same, that factor in what the solar system is generating at any given moment, and that can start preparing a home before anyone’s back to notice.
Not a gimmick it’s a shift in relationship
None of that is about chasing a colder house for its own sake, and it’s worth resisting the temptation to describe it as revolutionary. The air conditioner is slowly stopping being a separate appliance you switch on and off and starting to behave like part of a household’s broader energy system. Sitting alongside the solar already on the roof and for a growing number of homes, a battery down the side of the house.
The 3pm problem doesn’t disappear because of any of this. Homes will keep heating up through the afternoon, and someone will still have to decide what happens to the air conditioner while nobody’s there to feel it. What’s changed is simply the range of sensible ways to handle that decision; from the old, still-perfectly-valid rule of switching off completely, through to homes where solar, zoning and scheduling genuinely change the calculation.
There’s no new right answer to replace the old questions, but there are now enough different variables at play that the question is worth actually thinking through, rather than defaulting to whatever you’ve always done.
If you’re weighing up a smarter way to manage comfort in your own home, the right system design makes a real difference. Ford & Doonan can help you look at options including ducted air conditioning, zoning and smart controls.
