In the UK, 16 million homes built before 1960 have air-bricks installed to ventilate underfloor and indoor areas to prevent condensation. However, research has shown that vents left continuously open can lead to homes losing a considerable amount of heat. AirEx has developed a smart ventilation control that can be installed in place of the air-brick. Its sensors measure temperature, humidity and air quality while its algorithms enable automatic air flow regulation, while taking into account local weather and air quality data. AirEx opens to reduce underfloor humidity, and closes to reduce heat loss. The resulting flexibility in airflow can amount to a 10% to 15% reduction in energy bills.
Agnes Czako is Co-Founder and Managing Director of AirEx. Agnes joined the SME Leaders programme in 2020. She says: “Gaining new knowledge and tapping into a fantastic network of peers are two of the key elements for me. I think a course focusing on transformational leadership and leadership in a technology-driven world will be invaluable for me and the company.”
AirEx has received Ofgem approval and has market traction. The company is now aiming to rapidly scale up its business, hoping to be deployed in thousands of UK homes and across Europe where it’s estimated there are a further 35 million houses with old-fashioned air-bricks.
