Sustainable ventilation or eco-friendly ventilation

Green ventilation, also known as sustainable ventilation, refers to the practice of providing fresh air circulation and maintaining indoor air quality in a way that minimizes energy consumption and environmental impact. It involves the use of ventilation systems and strategies that prioritize energy efficiency, resource conservation, and occupant well-being.

Key aspects and features associated with green ventilation

Energy-efficient systems

Green ventilation systems aim to minimize energy consumption by utilizing efficient equipment and controls. This can include the use of VAV's, low-power fans, or heat recovery ventilators (HRVs) to reduce the energy required for conditioning incoming fresh air.

Natural ventilation

Passive or natural ventilation techniques rely on natural airflow and pressure differences to bring fresh air into a building. This approach may involve strategic window placement, vents, or stack effect (the principle that warm air rises) to facilitate air exchange. Natural ventilation can be enhanced by using sensors and automated controls to optimize airflows based on outdoor conditions

Demand-controlled ventilation

Green ventilation systems often incorporate demand-controlled ventilation (DCV) strategies. DCV adjusts the ventilation rate based on real-time occupancy levels, indoor air quality, temperature and humidity measurements via smart controls and sensors. This ensures that ventilation is provided when and where it is needed, optimizing energy efficiency while maintaining a healthy indoor environment.

Heat recovery

Heat recovery systems are designed to extract and utilize the thermal energy from outgoing stale air to pre-condition the incoming fresh air. This reduces the energy needed for heating or cooling the incoming air, resulting in significant energy savings. Heat recovery units incorporate high efficient air filters to remove particulate matter, allergens, and pollutants from the incoming air.
