Company Overview
AirEx is a British climate-tech company founded in 2016 with a mission to address fuel poverty and climate change. The company has developed and manufactures the world's first smart air brick, a patented IoT-enabled technology designed to make homes more energy-efficient. The system uses sensors to monitor environmental conditions like temperature and humidity, along with local weather data, to intelligently regulate airflow through a home's ventilation bricks. This process reduces unnecessary heat loss, which can account for up to 15% of a home's total, thereby lowering energy bills and carbon emissions without compromising indoor air quality. The technology is aimed at the building retrofit market as a low-cost, easy-to-install solution and is approved by the UK energy regulator, Ofgem.
