Keeping homes warm with smart airflow control. Many homes across Europe are naturally ventilated with air bricks. This air flow is essential in the home, but is responsible for a large proportion of a home’s heat loss. AirEx have created the world’s first smart air brick to reduce the home’s energy bills, helping to end fuel poverty and climate change with a simple building retrofit.

Story and ethos

We are a construction and climate tech company with a mission to tackle fuel poverty and climate change through novel, cost effective smart home solutions. We have designed and manufactured the world’s first smart air brick that helps householders and landlords reduce their energy demand whilst managing air quality in homes.

Heating buildings is responsible for 36% of CO2 emissions across Europe, poorly insulated, leaky, energy inefficient buildings require more energy to heat, resulting in higher carbon emissions. Recent research demonstrated that air bricks (air ventilation holes that provide natural airflow) are responsible for up to 15% of the home’s heat loss - this is equivalent to 34,000 GWh/year energy waste in the UK alone! Our solutions can mitigate this unnecessary waste through intelligently controlling airflow. We are disrupting the building retrofit market by providing a connected homes’ solution with technology that’s simple to install and simple to use.

Our mission is to combat fuel poverty and climate change through pioneering, affordable smart home solutions to create warm & healthy homes.
