Our TVs, toast makers, front doors, doorbells, and heating systems are smart. Could our brick walls be as well? According to Hungarian innovator Agnes Czako, the answer is yes.
After working in the housing energy assessment sector, Agnes Czako, now 35, focused on tackling energy poverty by using old building components of air bricks. In the United Kingdom, the air brick was initially created to allow air ventilation in affordable housing units. However, most of these air bricks would get blocked by tenants due to higher energy bills caused by increased heat loss. In turn, blocking them would result in dampness and major health risks, including respiratory diseases in children.
Before turning 30, Agnes founded and became the CEO of Airex, an innovative enterprise teaching the ‘old brick’ new tricks and making it smarter. Agnes’ Airex air brick regulates airflow per weather and heating demands, ensuring energy-efficient homes without compromising ventilation. Airex bricks are easy to install, pay for themselves through energy savings within two years, and are currently accessible free of charge for families in lower-income homes in the United Kingdom.
Airex provides 12 per cent savings on an average home's heating energy bills. In three years since its commercial launch, Agnes' team has already deployed over 10,000 units across the United Kingdom. If installed across Europe, it could potentially save up to 370 million tons of carbon emissions. This highly investable solution could be a game changer for homes, schools, health care facilities and all traditional air brick buildings. Reflecting on today’s global challenges, she says, “We need to keep pushing for change, for a better, more sustainable future."
