It’s still early to pick the word of the year, but “house burping” is gaining attention for 2026. This term has been trending online, especially among lifestyle influencers on platforms like Instagram and TikTok. But what exactly is “house burping,” and why should Australians care?
In simple terms, “house burping” means opening your windows to let in fresh air without losing energy efficiency. In Australia, most homes aren’t very airtight, which makes this concept less familiar. Tim Forcey, author of My Efficient Electric Home Handbook, likens many Australian homes to “glorified tents,” where outside air easily gets inside.
As we focus on making our homes more energy-efficient, house burping becomes important. In colder regions, the trend emerged during a warm winter, with many homes sealed tight to keep warm. By allowing fresh air in for just a few minutes, homeowners can reduce carbon dioxide and other harmful gases.
In Germany, they call it “lüften”—the practice of airing out space. In France, it’s “aérer,” and this idea has been common in Europe for centuries. Interestingly, some European countries even require it in rental agreements. In contrast, the name “house burping” has made it popular in America, leading to some light-hearted teasing from Europeans about Americans discovering the concept of fresh air.
For Australians, fresh air can play a crucial role in combating urban heat. Experts say keeping windows closed during the day can help keep homes cool. However, once the temperature drops, it’s a good idea to open them up.
House burping fits perfectly with the electrification trend, which involves switching from gas to electric appliances and sealing up any leaks or drafts. Forcey notes that key culprits for air leaks include chimneys and old wall vents, which were originally designed for homes using open fires.
“By sealing drafts, we gain control over ventilation,” says Forcey. For instance, he monitors carbon dioxide levels in his home and opens windows in the morning for just 15 minutes. This method avoids wasting energy by ensuring walls and furniture haven’t had time to heat up or cool down.
In Melbourne, Forcey has adapted house burping to his historic weatherboard cottage, while Susan Chan, a homeowner in Sydney, enjoys a nearly perfect indoor climate thanks to mechanical ventilation in her Passivhaus-certified home. This system provides a constant flow of fresh air without needing to open windows often, even during summer.
In terms of humidity, an airtight home allows for better control, which is critical as high humidity can lead to health issues and mold growth. Humidity levels in many Australian cities can reach 70% or higher, especially in winter.
Forcey relies on a dehumidifier, which he finds effective for managing indoor humidity, especially during winter. For summer, he relies on his air conditioner in dry mode, which uses less energy.
Sarah Aubrey, another advocate for home electrification, emphasizes the importance of controlling weather changes. She monitors humidity levels and has found success in reducing mold by sealing her home properly.
Ultimately, both house burping and effective ventilation are crucial for maintaining a healthy home environment. Whether through traditional ventilation or newer mechanical systems, ensuring fresh and clean air should always be a priority.
