Question
Do measured Outdoor Air (OA) ventilation rates in tenant-controlled areas meet minimum carbon dioxide (CO2) thresholds?
Applicability
Applicable to Light Industrial and Open-Air Retail buildings
Answer
Select one of the following:
- Yes
- No
- Not applicable – the tenant-controlled areas are not considered occupied spaces
Description
Where tenants manage IAQ, owner or landlords should be aware of operations and maintenance practices withing tenant spaces to check that tenant practices are not negatively impacting adjacent or base building components that are the owner or landlord’s responsibility.
Inadequate ventilation is one of the major sources of IAQ complaints and also an indicator that the HVAC system may not be functioning optimally. Odorous or dusty operations in tenant spaces have the potential to impact adjacent tenants if the contaminants are not properly controlled. The owner or landlord should ensure any high-risk tenants are diligent with their processes so adjacent tenants are not adversely impacted.
Requirements
- Demonstrate CO2 concentrations below 800 ppm:
- Refer to most recent IAQ Assessment Report and highlight section showing CO2 concentrations measured below 800 ppm in tenant-controlled spaces
- The assessment must have been completed within the last year
