Bridging the analog and digital divide for smart ventilation control
AirEx provides extremely low-cost solutions for reducing fabric heat loss, improving thermal comfort and protecting residents’ health by passive airflow control. Tens of millions of homes across Europe were built with low energy standards. Residents struggle with cold, uncomfortable draughts and high energy bills. However, the complete lack of airflow can cause damp or condensation problems. Traditional air bricks have uncontrolled airflow which allows houses to lose significant fabric heat loss - Airex replaces these with a smart alternative. The system measures the environmental conditions (such as temperature, humidity, air quality) and its cloud-based algorithms automatically regulate airflow, leading to 12-16% reduction in heat loss, resulting in 2-3 years payback. Social Landlords can access Airex free of charge (i.e. fully subsidised), thanks to its eligibility under govt schemes (£2bn/yr).
