Option 3. Verification of Ventilation and Filtration (1 point)
For spaces receiving mechanical ventilation from base building systems, measure the total quantity of outdoor air delivered to the project and verify the results are within 10% of the rates reported in EQp2: Fundamental Air Quality, and outlined in the current facilities requirements and operations and maintenance plan. Measurements shall quantify the amount of outdoor air for each base building air-handling unit serving the project, and account for worst-case conditions.
NOT E: This path is only applicable for tenant improvements to a previously occupied space and is not applicable for initial build-out.
REQUIREMENTS EXPLAINED
The credit incentivizes designing systems that continuously provide enhanced air quality during building occupancy. For measures that provide enhanced air quality only in specific circumstances, refer to EQc4: Resilient Spaces for more guidance .
Both options in this credit utilize measures described in ASHRAE Guideline 42-2023, Enhanced IAQ in Commercial and Institutional Buildings [114], with the goal of providing enhanced IAQ. Projects are encouraged to address additional measures from ASHRAE Guideline 42 beyond those included in this credit.
NOTE: If the VRP is being used for EQp2 Fundamental Air Quality, it is expected Option 1 for this credit will be used. However, it is not required. Review both options and choose the one that most aligns with your project goals for enhanced air quality.
Option 1. Increased Ventilation
Providing additional outdoor airflow, above the minimum requirements for ventilation and building pressurization, can further dilute and reduce indoor air pollutants. Research has shown increased ventilation may improve cognitive performance and associated productivity and income, reduce absenteeism in commercial offices115, and improve sleep quality in residential applications.
