Keep Occupants Healthy Enhance Ventilation and Ensure IAQ and Energy Effi ciency HVAC systems in densely occupied spaces are designed to accommodate the maximum expected number of occupants. However, this can lead to energy waste when the actual number of occupants is lower. Occupancy counters are eff ective in large spaces where CO2 levels take time to reach a steady state. They can quickly work with airfl ow measurements to adjust ventilation rates based on actual occupancy. Measure supply, return, and exhaust airfl ow rates to dynamically control pressurization fl ow Zone level measurement to determine ACH and adjust with variable occupancy Outdoor airfl ow measurement verifi es ventilation rates and integrates with the DCV for better control and limit under/over ventilation Notifi cation of problems with built-in Hi/Lo airfl ow alarm output or BAS integration monitoring
