IEQ Credit 1 for Mixed-Use Commercial-Residential Project

Hi Jean, we have some discussion of this in the Bird's Eye View and Checklists sections above.You'll be required to include a CO2 sensor in each unit, which for many projects won't be cost-effective. I don't know of a cost-effective way to get around this. What are your thoughts on this approach?

A question slightly related to the above.. the residential unit typically get its make-up air from operable windows plus pressurized corridors, plus neagtive pressure created by bathroom fans and kitchen exhaust which may or may not always be used(from CIR 3/15/2007). It also uses a VRF system. Each unit has multiple spaces such as 3 bedrooms, living and dining area (total area is around 1800sf, 6 or less persons per unit). For this case, is one CO2 sensor per residential unit enough to satisfy the credit?

(1)A building with ONLY densely occupied spaces (such as an assembly hall) or with MINIMAL non-densely occupied space: This is where it gets confusing.Yest Infection No More
