Inquiry

We have a new multi story app 195,000 sq ft College level school building. The building and the air-conditioning system are zoned to match similar functions. We have 7 air-conditioning systems: 1. Office areas: 5-story, two air-handling units combined into one system. 50,000 sq ft. This includes mostly private offices. There are just a couple of small open office/reception areas, two computer type 30 people classrooms, and four 20 people conference rooms. 2. Classroom areas: 4-story, two air-handling units combined into one system. 72,000 sq ft total. This includes 42 classrooms. Classroom size vary from 28-occupants to 60-occupants, and one 120-occupants classroom. 3. Library: 1-floor, one air-handling unit, 23,000 sq ft total, this includes stack areas, various reading areas, and few small meeting rooms 4. Atrium: 5-story, one air-handling unit, 17,000 sq ft total 5. Dinning room: 1-floor, one air-handling unit, 8,000 sq ft total, for 190 people. 6. Kitchen: 1-floor, one air-handling unit, 2,000 sq ft total 7. Retail space: 1-story, one-dedicated air-conditioning unit. 2,000 sq ft total We propose to have one CO2 sensor per each air-handling unit. Is the sufficient to achieve the intent of the IEQ credit 1? If not, what would it be required to achieve this point. Do we need to add more sensors? What would be the criteria/requirements for placing these sensors. Are there any particular locations where these sensors are required? In the case of the kitchen we proposed not to use a sensor since the kitchen is 100% exhaust air during operating hours.
