Simple, clever solutions for energy efficiency and healthy homes

Smart Air Bricks: Reducing heat loss and improving EPC ratings

At AirEx, we’re making homes more energy efficient with the world’s first smart air brick; a simple, smart solution for homes with suspended floors. 

The AirEx Floorvent replaces traditional air bricks. With built-in sensors and weather information it allows intelligent airflow, closing to reduce heat loss and improve thermal comfort and then opening to reduce humidity and stop damp and mould, depending on environmental conditions. 

It improves SAP scores by around 2–4 points, reduces draughts, and keeps homes warm. It’s easy to install. Plus, by cutting heat loss, it lowers energy bills for residents.

Retrofit upgrades can feel disruptive, leaving many residents hesitant. Floorvent is quick to install and non-intrusive. It requires no major work or access to the main living space. Once in place, it works automatically, keeping homes warm while preventing damp and condensation.

For housing providers and retrofit coordinators, it’s an affordable, high-impact solution suitable for many homes. Eligible within ECO4, Warm Homes: Social Housing Fund, and Warm Homes: Local Grant programmes, it helps projects stay on time and within budget.

Field trials showed an average 12% reduction in heat loss per home. Floorvent has been included in SAP since 2022, typically improving SAP scores by 2–4 points. Installation takes just one hour per property.

It can be installed under PAS2035/2030 standards and has been lodged for funding in previous SHDF waves. It is widely used under the Warmer Homes Scotland scheme and is now an eligible measure in ECO4.
