Across the globe, homeowners and designers are grappling with one big question: What’s the smartest way to make my home more energy-efficient — and is it worth it? Now, a team from Australia has launched the Powerhaus App, the world’s first public tool that shows — in real time — how changes to your home design affect energy use, carbon emissions and future power bills.
Fresh off its win for Most Innovative Solution – Environment and Energy Efficiency at the 2025 Australian Proptech Awards, the Powerhaus App is already being recognised as a breakthrough in sustainable housing technology.
Unlike traditional energy ratings, which provide a single score after plans are finalised, the Powerhaus App gives live feedback while you’re designing — helping you avoid expensive mistakes and make confident, low-carbon choices from day one. It’s a game-changer for anyone involved in green building — offering real-time feedback, not just compliance paperwork.
“People are being asked to make high-stakes energy decisions with low-quality information,” says Andrew Pickard, founder of Powerhaus Engineering. “We built the app so anyone — whether you’re a homeowner or a design professional — can see what actually works, and what it will save.”
Built on over 10 years of energy modelling and backed by Australian climate data, the app helps users:
- Compare design choices, in real time
- See how windows, insulation, solar and systems affect energy use
- Understand carbon impact and daily ‘net zero’ performance
- Prioritise upgrades by return on investment — not just intuition
Originally developed for internal consulting use, the app is now available for anyone to purchase directly via powerhaus.app. Whether you’re building a new home or upgrading an older one, it provides the clarity and confidence needed to design for a net zero future.
“Climate goals will be won or lost in how we design and upgrade our homes,” says Pickard. “This tool puts real impact in people’s hands — without needing a degree in building physics.”
