Inquiry

The project is a 455,000 square foot hospital with 12 airhandlers. Due to health care code requirements each patient room, recovery room, and observation room will be required to have 2 AC/hour of outside air. Invasive rooms such as operating rooms have higher outside air requirements. To meet this requirement outside air percentages in airhandler are maintained year round at a minimum of 33% or more for ALL patient care areas. This will cover about 80% of the hospital. Would installing CO2 sensors in all of the airhandlers, in spaces with variable occupancies such as dining rooms, nurse stations, conference rooms, and waiting areas meet the intent of the credit. We don\'t see a benefit to installing a CO2 sensor in each patient care area or surgical area due to the high outside air amounts delivered to each room.
