Question
Do measured Outdoor Air (OA) ventilation rates in owner or landlord-controlled areas meet minimum carbon dioxide (CO2), ASHRAE 62.1 or ASHRAE 62.2 thresholds?
Applicability
Applicable to Multi-Unit Residential buildings
Answer
Select all that apply:
- Yes – CO2 concentrations below 800ppm
- Yes – OA rates meet current ASHRAE 62.1 Table 6.2.2.1 minimum Requirements (corridors and common areas)
- Yes – OA rates meet current ASHRAE 62.2 minimum Requirements (residential spaces)
- No
Description
Maintaining adequate ventilation and thermal comfort within the built environment is important for occupant health and safety, comfort, and productivity.
Inadequate ventilation is one of the major sources of IAQ complaints and also an indicator that the HVAC system may not be functioning optimally.
Requirements
a. Demonstrate CO2 concentrations below 800ppm:
- Refer to most recent IAQ Assessment Report and highlight section showing CO2 concentrations measured below 800ppm in owner or landlord-controlled spaces
- The assessment must have been completed within the last year
b. Demonstrate ASHRAE 62.1 Table 6.2.2.1 minimum Requirements are met:
- Determine the average ventilation rate for frequently occupied indoor spaces through on-site measurement of actual outdoor and supply air through the use of a certified air balancing contractor or equivalent
- The assessment must have been completed within the last five years, or as major renovations of the HVAC systems occur
Documentation
- Table showing CO2 concentrations measured below 800ppm
- Table comparing calculated and measured based on ASHRAE 62.1 Table 6.2.2.1 ventilation rates
