Ventilation Rate (VR) is an important indicator for evaluating building energy efficiency and air quality in green buildings. Laser gas sensing technology accurately calculates the building's VR by monitoring the difference between indoor and outdoor CO₂ concentrations, enabling intelligent adjustment of the ventilation system. In addition, the technology can also detect the indoor concentration of formaldehyde, VOCs and other harmful gases, further enhancing the environmental healthiness of green buildings.

1. Air Change Rate Monitoring: Arrange laser gas sensors in the ventilation system to detect CO₂ concentration in real time and calculate the air change rate by combining the airflow speed and volume to dynamically adjust the ventilation intensity.

2. Air Quality Control: Monitor the concentration of indoor VOCs, CO₂ and other pollutant gases, and linkage of air purification and ventilation equipment to achieve intelligent regulation.

3. Building Energy Efficiency Management: Integrate the VR data into the building intelligent management system, dynamically adjust ventilation, cooling and air purification equipment to reduce building energy consumption.

Traditional Methods: Offline sampling or fixed model to calculate the ventilation rate, real-time and low precision

Laser Sensing Advantages:

• Accurate Real-Time Monitoring: Dynamically calculates the VR based on the difference in CO₂ concentration;

• Multi-Gas Simultaneous Detection: Taking into account formaldehyde, VOCs and other harmful gases monitoring, to ensure comprehensive air quality

• Combination of Energy Saving and Intelligence: Reduce energy consumption by optimizing the VR and improve the overall energy efficiency of the building
