"We identified a huge untapped potential in the energy-saving impact of controlling air-bricks. These air bricks (air vents) were originally built in to provide natural ventilation to the building (53 million homes across Europe)".

• Air Bricks which are constantly open can lead to c. 15% of the homes' heat loss.
• Blocked Air Bricks cause damp and poor indoor air quality, which can cause respiratory illnesses (such as asthma). Especially now as a result of covid19.
