Heat Recovery Ventilation (HRV) systems are designed to improve indoor air quality and energy efficiency by exchanging stale indoor air with fresh outdoor air while recovering heat from the outgoing air to warm the incoming air. This process reduces the energy needed for heating or cooling, making HRVs a vital component in modern, energy-efficient buildings.

Heat Recovery Ventilation

Indoor Air Quality (IAQ) refers to the condition of the air inside buildings, influenced by pollutants, ventilation, and humidity, which can significantly impact health, comfort, and productivity. Effective management of IAQ involves identifying sources of pollution, ensuring adequate ventilation, and maintaining optimal humidity levels to minimize health risks and enhance well-being.

Energy efficiency refers to using less energy to perform the same task or produce the same outcome, thereby reducing energy waste and lowering energy costs. It is a crucial component in combating climate change and enhancing energy security by minimizing the environmental impact of energy consumption.
