10 years
VENTILATION DESIGN
One of the following requirements is met for all spaces:
- Ventilation rates comply with all requirements set in ASHRAE 62.1
- Projects comply with all requirements set in any procedure in ASHRAE 62.1-2013 and demonstrate that ambient air quality within 1 mi of the building is compliant with either the U.S. EPA’s NAAQS or passes the Air Quality Standards feature in the WELL Building Standard for at least 95% of all hours in the previous year.
DEMAND CONTROLLED VENTILATION
For all spaces 500 ft² or larger with an actual or expected occupant density greater than 25 people per 1,000 ft², one of the following requirements is met:
- A demand controlled ventilation system regulates the ventilation rate of outdoor air to keep carbon dioxide levels in the space below 800 ppm (measured at 4-6 ft A.F.F.).
- Projects that have met the Operable windows feature demonstrate that natural ventilation is sufficient to keep carbon dioxide levels below 800 ppm at maximum intended occupancies (measured at 4-6 ft A.F.F.).
SYSTEM BALANCING
After the HVAC system is installed, the following requirement is met:
After substantial completion and prior to occupancy, the HVAC system has (within the last 5 years), or is scheduled to, undergo testing and balancing.
